Wave generator for swimming pool

Abstract

A pool wave generator having a pool area and a plurality of chambers for generating waves in the pool area is disclosed. The example embodiments described herein can be used to control fluid flow within the pool area. For example, the example embodiments can include beveled lateral walls on opposite sides of a wall comprising the plurality of chambers. The example embodiments can also include one or more additional water structures for receiving, controlling, and / or directing water from wave generation. The water structures can be configured to reduce the amount of water that is directly backflowed into the water at the same location where the water exits, thereby minimizing the flow of water back into the water toward the plurality of chambers.

Description

BACKGROUND

[0001] Water parks have brought joy to different people in different geographical locations for generations. Water parks allow different geographical areas to obtain simulated experiences from other geographical areas. For example, wave pools can approximate a beach experience.

[0002] Different water parks can be used to approximate natural environments to allow users to experience the motions and activities from those other environments. For example, sheet wave riding simulates a surfing or bodyboarding experience that allows riders to ride a sheet of water contoured by an underlying riding surface with their bodies or a thin board. Since sheet wave riding does not allow for wave breaking or the use of a true surfboard, sheet wave riding cannot provide a true surfing experience.

[0003] Deep wave surfing systems are provided that attempt to more accurately approximate a surfing experience in a natural environment. U.S. Patent Nos. (USPN) 8,434,966; USPN 9,103,133; USPN 9,279,263; USPN 10,145,135; USPN 10,280,640; and USPN 10,526,806 disclose deep wave surfing simulators, each of which is incorporated by reference in its entirety.

[0004] Deep wave riding presents unique challenges to managing the large amounts of water used in the ride. For example, water flows and eddies can form that disrupt wave formation. SUMMARY

[0005] A pool wave generator is disclosed having a pool area and a plurality of chambers for generating waves in the pool area. The plurality of chambers can be used to retain or release water into the pool to generate desired wave formations.

[0006] Exemplary embodiments described herein can include unique pool configurations for managing water flow to affect the water flow. Such exemplary configurations can be used to generate and maintain desired wave formations and / or allow for continuous or timely formation of repeating waves along the length of the pool to minimize the elapsed time between wave formations. Accordingly, exemplary embodiments can include a catch pool and / or trough located at the shallow end of the pool to direct water at the end of a wave. The catch pool and / or trough can be used to absorb and / or dissipate water flow within the pool. In exemplary embodiments, the pool can be configured to have a pool floor that slopes upward to create a beach area. The catch pool and / or trough can be configured relative to the shallow area of the beach area such that wave energy washes over the high tide line of the beach area and into the catch pool and / or trough to dissipate the wave energy and resulting water flow. The catch pool and / or trough can be configured to redirect the captured water back into the pool and / or chambers. The trough can be covered and / or uncovered. BRIEF DESCRIPTION OF DRAWINGS

[0018] ​​​The following detailed description illustrates by way of example, not by way of limitation, the principles of the application. This description will clearly enable one skilled in the art to make and use the application, and will describe several embodiments, adaptations, variations, alternatives and uses of the application, including what is presently believed to be the best mode of carrying out the application. It should be understood that the drawings are diagrammatic and schematic representations of exemplary embodiments of the present application, and are not limiting of the present application, nor are they necessarily drawn to scale.

[0019] Exemplary embodiments described herein include a pool configured to generate waves. The pool can include one or more chambers at one end that are configured to receive water and release the water into the pool to generate waves. Exemplary chambers are provided to reduce turbulence and generate better waves for riding. The pool can be configured to generate waves that define or create different profiles and / or areas for riding by different experience levels of riders. The pool can also be configured with a bottom profile and / or include additional water features, such as a catch pool and / or channels for controlling water flow to dissipate wave energy and control water flow.

[0020] While embodiments of the present application can be described and illustrated herein in terms of a pool wave generator with unique and novel features, it should be understood that embodiments of the present application need not or necessarily include every feature. The present disclosure need not include any particular component, configuration, or feature, and any combination of features can be incorporated or combined and remain within the full description of the present application. For example, including an elongated chamber between the chamber and the pool to reduce turbulence can be used in any conventional feature of a pool wave generator. Similarly, including a spectator area, and / or a bottom profile to create different wave areas can similarly be used alone or in combination with other features described herein.

[0021] Figure 1A An exemplary wave pool according to embodiments of the present application is shown. An exemplary pool wave generator 10 can include a pool area 12 and one or more chambers 14 for generating waves within the pool area. Waves 16 can propagate away from the chamber(s) 14 and toward an end 18 of the pool.

[0022] In exemplary embodiments, the pool area 12 can be a recessed pool configured to hold water. The end 18 can be a wall for retaining the water. The wall can be vertical or can be sloped. In exemplary embodiments, the end is formed by a sloped bottom of the pool to approximate or resemble a beach area. As water is pushed across the pool area 12 by releasing water from the chamber 14, the water can travel toward the end and across and up the sloped bottom until the water stops and eventually returns down the sloped bottom under the influence of gravity back to the pool area.

[0023] Figure 1AAn example pool wave generator is shown that includes two sides in which waves can travel from the chambers to opposite ends of the pool. This can be used to create different zones that can have similar or different wave profiles for use by different riders. Different zones can be used to create waves for riders with varying levels of experience. An example embodiment includes a pool wave generator in which waves travel in a single direction, such as Figure 1B is shown in FIG. 1 1.

[0024] The chambers 14 can sequentially release water into the pool zone 14 as shown by the arrows adjacent to the chambers 14. The chambers can be linearly aligned along one side of the pool 12. The chambers can also include different orientations, configurations, and orientations. The release of water from the chambers can be used to control wave properties such as wave height, direction, shape, etc. As shown, the chambers toward the middle of the plurality of chambers are released together and then the chambers can be released in sequence moving outwardly toward the opposite ends of the plurality of chambers. The chambers can also be configured to release in different directions or sequences such as from one end to the other or from opposite ends toward the middle of the plurality of chambers.

[0025] Figure 1A An example embodiment is shown in which a linear arrangement of chambers is provided along one edge of the pool zone 12. The chambers can traverse the entire length of the pool edge. As shown, the lateral side of the pool wall 19 can extend at a non-zero angle from the end of the last chamber on the pool edge, the angle being measured from the linear extension of the pool edge defined by the chambers. In other words, the lateral wall can extend directly forward from the end of the chamber. The lateral wall can also have a component that extends outwardly on a continuous extension of the linear direction of the chambers at a non-zero, non-perpendicular angle to the linear extension of the pool edge that includes the chambers. Angling the pool wall can reduce the amount of water needed to fill the pool and reduce the pool area that can create less desirable wave effects.

[0026] Figure 1C An example vector modeling of the speed of water and corresponding waves during wave generation for an example pool wave generator according to embodiments described herein is shown. As shown, a defined wave zone can be seen as the wave traverses the length of the pool. As shown by the dashed box in the middle of the pool zone, the pool can include a dead zone that can be used as a paddling passageway into the wave zone and / or a waiting area.

[0027] According to embodiments described herein, angling the opposing lateral sides can also be used to control water flow in the pool. Figure 1D An example wave water speed diagram is shown in which the pool has extended walls at the opposite ends of the pool wall that includes the chambers. As shown, the pool experiences a significant backflow of water toward the flat wall. This creates a vortex at the end of the chambers that can interfere with wave propagation. Figure 1EAn exemplary wave velocity diagram with a pool having sloping walls is shown according to an embodiment described herein. Unexpectedly, removing the water flow path back into the chamber reduces the eddies generated at the ends of the chamber. It is believed that the sloping walls concentrate the remaining wave energy, which can then be used to generate the intermediate wave riding region according to the embodiment described herein. The wave velocity diagram shows the water velocity during wave generation, where arrows indicate direction and quantity (larger areas represent larger speeds or faster waves).

[0028] The exemplary embodiments described herein may include a pool having a first linear edge, wherein a plurality of chambers are configured to fluidly connect and distribute water into the pool along the first linear edge. One or more chambers may be configured along the entire first linear edge. The pool may include two opposing lateral sides extending from the end of the first linear edge. The opposing lateral sides may extend at an angle to the front of the first linear edge. The angle of each lateral side may be the same or different, depending on the configuration of the pool. The opposing lateral sides may extend outward and forward at an oblique angle from the first linear edge. Exemplary embodiments of angled opposing lateral sides may contribute to flow mitigation. Exemplary embodiments of angled opposing lateral sides may also concentrate wave energy, allowing waves to be reformed for different experience levels.

[0029] Figures 2A-2C An exemplary wave-generating chamber and its associated controls are illustrated for generating waves in a wave pool as described herein. Chamber 20 can be configured to maintain water at a chamber level 28, and when released into the pool, the pool level 26 increases, generating waves 26' that propagate away from chamber 20 and across the pool. The chamber may include one or more valves 22, 24 for controlling the holding and releasing of water in the chamber. In one exemplary embodiment, a first valve 22 controls the flow of water into and out of chamber 20. In one exemplary embodiment, a second valve 24 controls the flow of air or fluid into and out of chamber 20. The second valve 24 can be used to introduce pressurized gas into and / or expel gas from the chamber to assist the movement of water into and out of the chamber.

[0030] like Figure 2A As shown, the system may have been released, resulting in no water in chamber 20 or a low water level 28 in the chamber (such as...). Figure 2C (As shown). The second valve 24 can be opened to purge air from the chamber. The chamber can be configured to vent air from chamber 20, thereby pressurizing the chamber negatively. The vent 24 can also be opened to bring chamber 20 to a neutral pressure and allow air to escape from the chamber when it is filled with water. The first valve 22 opens, and water rushes into the chamber, raising the water level in the chamber.

[0031] like Figure 2BAs shown, the first vent 22 is closed to maintain the chamber water level 28 at a height above the pool water level 26. The chamber can then be filled with pressurized gas to exert additional pressure on the water within the chamber. The second valve 24 is then closed, and the first valve is opened.

[0032] As Figure 2C shown, the pressurized air in the chamber pushes the water level 28 in the chamber, which in turn causes the water to rush out of the chamber to create a wave 26' that propagates across the pool. The first valve 22 can be closed, and the air in the chamber is vented, such as through the second valve 24. The first valve 22 can be closed to limit the amount of water that is allowed to back up in the chamber, thereby minimizing interference with the wave 26' that is created. The first valve 22 can also remain open to allow water to back up into the chamber, and be closed as discussed with reference to Figure 2B .

[0033] In exemplary embodiments, the system is configured to cycle through the process of releasing water from the chamber and allowing water to surge back into the chamber. The system can also include a delay after any number of cycles to allow the water in the pool to settle and reduce turbulence that can affect wave generation.

[0034] In the exemplary embodiments provided, two valves are shown - a first valve 22 for water control and a second valve 24 for gas control. Any combination of valves can be used, and these combinations are within the scope of the present disclosure. For example, multiple gas valves can be used to vent the chamber, inject pressurized gas, etc., and multiple fluid valves can be used to release or retain water within the chamber. The sequence and / or cycling of valves described herein are merely exemplary. Any number of different ways can be used to release waves using valves, gates, or other methods. Valves can be opened, closed in different ways. For example, the system can use a purge system to remove gas from the chamber before water is regenerated, thereby raising the water level that is allowed to back up into the chamber. For example, the system can not use a pressurized gas system to expel water into the pool. For example, one-way valves can be used so that the valves do not need to be individually actuated to open and close. The valves for each chamber can be controlled individually or as a sequence within the larger operation of the entire pool system.

[0035] Figure 3 An exemplary wave pool 30 is shown that is configured to generate different regions of waves having different wave characteristics in accordance with embodiments of the present disclosure. In one exemplary embodiment, the pool contour 32 and pool floor 34 can be shaped to define a desired wave contour and / or to generate multiple wave regions 36, 37, and 38.

[0036] In example embodiments, multiple wave zones 36, 37, 38 can be created. The creation of multiple wave zones can be created from a single wave creation cycle of the chamber. For example, the chamber can release in sequence to create a first wave. This first wave can change profile, height, direction, etc. The wave can also deteriorate and / or reorganize based on the underlying topography of the pool bottom. As shown, on one side of the pool, three wave zones are created for a single wave creation cycle. The pool can have a mirrored configuration such that the entire pool has six wave zones. However, three of the wave zones are independent of the other three because the wave or portion of the wave that creates the first three wave zones is different than the wave or another portion of the wave that creates the last three wave zones. Any combination of wave zones can be created and for two sides, three zones per side, a combination of six zones total is merely illustrative. In example embodiments, a wave pool can have only one, two, three, or more wave zones. The pool can have a mirrored configuration such as the configuration in Figure 1A , thereby doubling the wave zones, or the pool can be single sided as in Figure 1B . Opposite sides of the pool can also be configured differently such that different wave zones can be created across the entire pool.

[0037] As shown, the first wave zone 36 is adjacent to the wave creation chamber. The wave in this section is the highest. This zone can be for the most experienced riders. It can also be used for shortboard riders.

[0038] As shown, the second wave zone 37 can be in the area of the pool after the wave exits the chamber that extends along the sidewall or edge of the pool. After the wave propagates out from the chamber, the wave will dissipate energy and lower in height. Thus, this zone is created for intermediate riders and longboard riders.

[0039] As shown, the third wave zone 38 can be adjacent to the side of the pool away from the chamber. This edge can correspond to the beach area 46’ of the pool. This zone can be shallow in depth and can have a sloped bottom. The first wave zone 38 can be for beginner wave riders. This zone can also be for bodyboarding or boogie boarding. This zone can also be for body surfing or wave jumping.

[0040] The bottom of the pool can have areas that correspond to or affect the wave zones. For example, a first area 42’ of the pool bottom generally corresponds to the first wave zone 36, a second area 44’ of the pool bottom generally corresponds to the second wave zone 37, and a third area 46’ of the pool bottom generally corresponds to the third wave zone 38. A fourth area 44’ and / or other areas can be used to create and separate different wave zones and / or to reform the wave as it propagates from the chamber. The different areas of the pool bottom will be discussed more fully with respect to Figure 4 .

[0041] Different bottom regions can be used to influence the wave profile. For example, the depth of the bottom can influence the wave size, while the slope of the bottom can influence the wave shape. Thus, a first region 42' adjacent to the chamber can produce a wave area 36 for the most experienced riders. This region can be approximately 2-6 meters deep. Thus, the bottom of this region can have a greater slope or grade toward the shore or opposite side of the pool, and / or can have the greatest depth. A third region 46' can be adjacent to the short side or edge of the pool away from the chamber, and can produce a wave area 38 for the least experienced riders. Thus, this region can have a bottom with a minimal slope or grade toward the edge and / or can have the shallowest depth. A more gradual slope can make the wave breaking more gentle.

[0042] In example embodiments, the edges of the pool away from the chamber can also be contoured to influence wave characteristics. For example, in the region of the third wave area, or in the beginner's area, on the side of the pool opposite the middle chamber in the sequence of chambers, the edge can be raised toward the middle of the pool. This raised area can form a shore or dry indentation in the side of the pool. As the wave travels across the pool from the chamber toward the shore, the wave can wrap around the raised area extending into the pool area. Other or additional raised areas can be provided along the short sides to form additional wave areas. In example embodiments, the raised areas can be used to separate and / or redirect waves.

[0043] As shown, the chambers can release water sequentially into the pool, creating waves. If the middle chamber in the sequence of chambers is opened first, and then the chambers are sequentially opened in the opposite direction toward each end, the left and right waves will travel from the chambers and break at approximately the same time. The chamber sequencing can also be delayed or offset so that the left and right breaking waves can be staggered. A professional wave area can be defined as the area adjacent or proximate to the chambers. Waves within the professional wave area can break along the wave generating wall. The waves can remain approximately constant in height as the sequential release of water from the chambers can be used to maintain wave formation. In example embodiments, the wave height in the professional wave area can be approximately 1.5 to 3.5 meters. After the waves exit the area proximate to the chambers, the waves will dissipate energy and the wave height will decrease. Waves extending along the side edges of the pool away from the chambers can form an intermediate wave area with a decreased wave height relative to the professional wave area. In example embodiments, the wave height in the intermediate wave area can be approximately 1-2 meters. The wave height can continue to decrease as the waves exit the chambers. The waves can then break along the opposite sides of the pool in the shallow water area to create a greater wave area. In example embodiments, the wave height in the beginner wave area can be approximately 0-1.5 meters.

[0044] Figure 4 A schematic representation of a pool wave system 40 is shown in FIG. 1. The pool wave system 40 can include a pool 42, a sequence of chambers 44, and a wave generating wall 46. The pool 42 can be a body of water, such as a swimming pool, a lake, a river, or an ocean. The pool 42 can be a body of water that is suitable for wave generation. The pool 42 can be a body of water that is suitable for wave generation.Figure 3 The exemplary bottom contours of the different wave regions described in the text. Figure 5A It has a reference line of 50. Figure 4 An illustration of an exemplary bottom outline. Figure 5B It shows along Figure 5A A cross-sectional perspective view of reference line 50 is provided to show the bottom of the pool. As shown, the bottom outline may include at least three areas.

[0045] In an exemplary embodiment, the first region 42 may correspond to the region adjacent to the chamber 14. For example... Figure 5B As shown, the pool bottom 52 of this region may include a gentler upward slope, such that the pool adjacent to this chamber is deeper than the pool on the opposite side of this region 42. This slope may extend from deeper to shallower at an angle α across the region away from the chamber. The first region 42 may be generally rectangular and extend directly in front of the chamber, as... Figure 4 As shown. The first region 42 may also open outward at its ends, such that the region spans the front of the chamber, and as the region tilts away from the chamber, it extends outward beyond the ends of the chamber, as shown. Figure 3 As shown. Other shapes for this area can also be considered.

[0046] In one exemplary embodiment, the third region 46 may correspond to a region on the opposite end of the pool forming chamber 14. The third region 46 may be on one side of the pool corresponding to the end of wave propagation opposite the origin of the wave. The pool bottom 56 of this region may have a gentler slope than the region adjacent to the chamber. The pool bottom 56 may include a gentler upward slope, such that the pool is deeper toward the first region 42 than the region on its opposite side. The end of this region may have zero depth, such that water washes to one side of the surface. This region may approximate a beach area. The slope may cross the region at an angle β from deeper to shallower in a direction away from the chamber. This region may correspond to a band or width at the end of a wave on the side of the pool opposite the chamber. Since the chamber can generate waves that propagate away from the chamber at an angle and not directly perpendicular to the chamber, the opposite end of the pool may be offset and include a portion of the pool terminating beyond the lateral end of the chamber. Therefore, opposite can include direct or geometrical opposite as well as opposite based on the propagation of waves generated from the chamber.

[0047] As shown, the third region 46 can be shaped in a curve such that some portions of the region are further from the chamber than other portions of the region. For example, the shore region 46' can be curved such that the portions of the shore region adjacent to the lateral sides of the pool corresponding to the ends of the chamber and toward the middle of the shore (for a mirrored pool) or the opposite lateral side of the pool (for a one-sided pool) are positioned closer to the chamber than the region between them. As shown, the shore region or the side of the pool opposite the chamber can thus include three curved regions, two outer regions on opposite ends of the shore region, where the regions are concave regions inward toward the chamber, and an inner curved region between the two outer regions in the middle of the shore region is a convex region outward toward the chamber.

[0048] As shown, the second region 44 can extend from the first region 42 to the third region 46. The region can similarly be sloped. The slope of the region can be linear, curvilinear, or curved. The region can include a gradual slope that transitions the bottom surface from the first region 42 to the third region 44. The region can also contour to provide a transition to any other regions that can be included in the bottom contour. The second region 44 can thus provide a transition surface between two or more other bottom surfaces or regions.

[0049] The pool can include one or more other pool bottom regions that define one or more other regions. For example, the first wave region can be separated from the third wave region. The separation can be to create a pool bottom contour to recreate a desired wave formation. The separation can allow space between the various wave regions for rider safety and / or rider enjoyment. As Figure 3 、 4 As shown in FIGS. 5 and 5', a transition region 48, 48' can be used. The transition region 48, 48' can correspond to a generally flat pool bottom 88. The transition region can be between the first region 42 and the third region 46 and / or the shore region. As shown in FIG. 5, the first region 42' can be in contact with the third region 46' in the middle of the pool, while the transition portion 48' separates the first region 42' from the third region 46' toward the lateral sides of the pool adjacent to the second region 44'. In one example embodiment, such as shown in FIG. 5, the transition region 48 can separate the first region 42 from the third region 46 along the length of the pool such that the first region 42 does not contact the third region 46. Figure 3 Figure 4

[0050] ​​In one example embodiment, the slope of the pool floor 52 corresponding to the first region 42, 42' is greater than the slope of the pool floor 56 corresponding to the third region 46, 46' (a > b). In one example embodiment, the slope of the pool floor of the second region 46, 46' is generally equal to either one of or between the slopes of the first and second regions (a > 0 > b). The pool floor 52 can have a pitch between 3 and 10 degrees. The pool floor 56 can have a pitch greater than 0 degrees to 5 degrees. The pool floor corresponding to the second region 46, 46' can have a pitch of 2 to 10 degrees.

[0051] The configurations, shapes, elevations, pitches, and other features of the pool floors described herein are exemplary only. Other or additional features can be added and are within the scope of this specification. For example, additional pitched pool floors and / or one or more other horizontal pool floor regions can also be included to create additional wave regions and / or separate wave regions. Other elements can also be included, such as pool floor configurations, walls, partitions, elevations, beach features, etc., to further enhance the surfing experience or provide additional benefits to the pool wave generators described herein. These can include features for splitting, redirecting, reforming, or otherwise affecting the generated waves.

[0052] Figure 6 An example wave generating chamber according to an embodiment of the present application is shown.

[0053] In conventional chamber configurations, the chamber and pool share a wall, or where the chamber and pool are in close proximity, creating a vortex through the area between the chamber and pool. The vortex can interfere with the shape and stability of the generated wave. USPN 10,526,806 discloses a vane positioned between or near the interface of the chamber and pool to control and direct the movement of the water and reduce the formation of a vortex. This system creates configuration and maintenance costs due to the vane having to be internally supported and maintained. The example embodiments described herein allow for the formation of a wave pool that can manage or reduce the formation of a vortex without the need for a vane or internal structure within or near the water flow path between the chamber and pool.

[0054] The configuration of the chamber 62 and the chamber 62 to the pool 64 can be used to create waves with desired characteristics. Exemplary embodiments use a chamber width CW and a width (wall width) WW between the pool and the chamber. In exemplary embodiments, the width WW between the pool and the chamber is greater than 2 meters. However, a greater distance in this transition area between the chamber and the pool can affect and reduce the height of the waves created. Thus, traditionally, it is desirable to keep this area as short as possible. However, this distance can be used to reduce turbulence and create a better wave profile. In exemplary embodiments, the distance between the edge of the pool and the edge of the chamber is between 2 meters and 7 meters. The chamber width CW can affect the final height of the waves created. Similar to the wall width WW, this dimension is typically reduced because additional width requires additional power to control and release the waves. For example, additional gas is required to create the same pressure on the water surface. The chamber width CW is preferably 1.3 to 5 meters.

[0055] In one exemplary embodiment, the chamber 62 can be connected to the pool 64 by a channel 66. The channel can be at a lower depth than the pool 64 so that water exits the chamber and enters the pool at or near the bottom of the pool. The channel can be shaped so that the direction of the water exiting the channel can have a vertical component. The channel can include an inner wall 68B and an outer wall 68A. The inner wall 68B and the outer wall 68A can be curved in order to reduce turbulence imparted on the water as it passes from the chamber through the channel into the pool.

[0056] Figure 7 An exemplary cross-sectional profile of a wave pool according to embodiments of the present application is shown. The exemplary wave pool 70 can include any combination of features as described herein. For example, the system can include a pool 64 having a pool floor. The pool floor can have one or more distinct areas, such as a first sloped area 52 adjacent to a chamber 62, which transitions through a generally flat transition area 54 to a third sloped area 56. The chamber 62 can control water in and out of the chamber through one or more valves 22, 24, as described herein.

[0057] As described herein, the end of the pool 64 facing the chamber can be separated from the chamber by a width WW. In exemplary embodiments, the separation between the chamber and the pool can allow for viewing by spectators. As shown, the space between the pool 64 and the chamber 62 includes a floor 78 on which a viewer can stand. The floor can be located around the water level of the pool 64, or at a higher location in order to provide better viewing for the riders in the area adjacent to the chamber or the rest of the pool. The area can include a bleacher 76 or other seated area or walkway to allow for foot traffic and / or viewing of the activity within the pool.

[0058] In example embodiments, separation between the chamber and the pool can allow for storage of system components in addition to or instead of spectator viewing. For example, the area between the pool 64 and the chamber 62 above the passageway 66 can include space for an air chamber, pump equipment, a blower, electronics, a controller, equipment room, or other system components. As shown, the grandstand or seating area can include an equipment room 86. The space below the floor 78 or between the chamber and the pool can include other components, such as space for an air chamber, electronics, a controller, or other equipment. As shown, the area between the pool and the chamber includes space for an air chamber 84, and an electrical room is positioned behind the chamber 86.

[0059] In example embodiments, the space between the pool 64 and the area 72 between the pool and the chamber 62 can be open and / or unobstructed. In this case, riders, swimmers, and / or lifeguards are able to enter the pool area from the floor 78 on the wave-generating side of the pool. In example embodiments, the wall 74 can extend above the height of the water to separate the space between the pool and the chamber from the pool itself. The wall 74 can be an extension of the pool side above the passageway entrance. The wall 74 can be acrylic, plastic, or other translucent or transparent material to allow viewing of activity in the pool from locations outside the pool. The wall 74 can protect observers from getting wet or accidentally falling into the pool.

[0060] Example embodiments described herein can include unique pool configurations for managing water flow to affect the water flow. Such example configurations can be used to create and maintain desired wave formations and / or allow for repeated wave formations to be created continuously or in time along the length of the pool to minimize the time between wave formations. Thus, example embodiments can include a catch pool and / or trough located at the shallow end of the pool to direct water at the end of a wave. The catch pool and / or trough can be used to absorb and / or dissipate water flow within the pool.

[0061] As previously described with respect to Figure 1A Example wave pool generators can include a pool area and one or more chambers for creating waves within the pool area. The waves 16 can travel away from the chamber(s) and toward the end of the pool. The end of the pool can be formed by a sloped bottom of the pool to approximate a beach area. When water is pushed across the pool area by releasing water from the chamber, the water can travel toward the end and through the sloped bottom and up the sloped bottom until the water stops and eventually returns to the pool area along the sloped bottom under the influence of gravity. However, the water returning to the pool can create a flow that disrupts the repeated wave generation. Thus, example embodiments can include additional water features to handle the movement of the water.

[0062] Figure 8An exemplary embodiment of a wave pool is shown having a pool area 181 and one or more chambers 14 to generate waves 182 that move from the chamber to a beach area 185. The beach area can be formed by a pool floor that tapers upwardly so that the water level of the pool area 181 and the pool floor meet. An incoming wave 182 can push water up onto the beach area 185 so that the location where the water meets the beach changes as the wave progresses. Thus, the beach area 185 can include a high water line 184, which can be the highest level (or further away from the chamber) that water can reach on the beach area 185 at a given wave progression. The high water line 184 can depend on factors of the wave generating apparatus, including chamber release time, pressure within the chamber, etc. A low water line can be the location along the beach area 185 where the water naturally rests on the pool floor without waves, or the lowest location (closest to the chamber) where the water rests when waves are generated.

[0063] Exemplary embodiments described herein can include a puddle pool and / or channel where the pool floor reaches the highest location in the beach area 185. The pool floor can then stop rising or fall so that water can be trapped in a second pool area 183. The second pool area 183 can be shallow to form a wading pool or puddle pool, or can be deeper to form a channel or trench to direct water. The second pool area 183 can be used to trap water from the pool area 181 based on the wave 182 passing through the beach area 185 and into the second pool area 183. This water trapping can reduce the water that is recirculated to the pool area 181 and reduce the adverse effects of the water flow created by the receding water.

[0064] The highest point of the beach area before transitioning to the second pool area 183 can occur between the low water line and the high water line of the pool area 181, adjacent to the low water line, at the low water line, or a combination thereof along the beach area. For example, as shown, the highest point of the beach area on the lateral outer edge of the beach area 185 can be adjacent to or within the low water line so that the pool area 181 and the second pool area 183 can be in fluid communication regardless of the generation of waves. The highest point of the beach area toward the center of the pool can be either outside or at the high water line 184 so that the pool area 181 and the second pool area 183 are separated by the gap 186 of the raised pool floor so that these pools are not in fluid communication through this gap (but can be through other areas along the beach area). The highest point of the beach area can also be between the low water line and the high water line so that the pool area 181 and the second pool area 183 are in fluid communication along this portion of the beach area only when waves are generated and propagate through the beach area. In this case, water is trapped as it is pushed up onto the beach and does not recirculate directly to the pool area 181 from the exit location.

[0065] As Figure 8As shown, a combination of relative positions and separations between the first pool area 181 and the second pool area 183 can be used. As illustrated, the first and second pool areas can be fluidly connected along the length of the beach area from the outer edge towards the center during wave generation. The highest elevation of the pool bottom between the first pool area 181 and the second pool area 183 can be approximately equal to or between the low waterline and the high waterline. The first pool area 181 can be separated from the second pool area 183 by a gap 186 towards the center of the pool area, such that the highest elevation of the pool bottom between the first pool area 181 and the second pool area 183 along this gap is approximately equal to or higher than the high waterline.

[0066] like Figure 8 As shown, additional pooling features may also be included. For example, pool 187 may be in fluid communication with the second pool area 183 and the first pool area 181. Pool 187 may be a shallow area to allow water to flow from the second pool area 183 back to the first pool area 181. As indicated by the arrows, water can be controlled through the second pool area 183 to capture water from the first pool area when waves are generated. The water then travels along the second pool area 183 to recirculate back into the first pool area at a desired location. Figure 8 As shown, the desired location is in the central area of ​​the beach area. (See figure.) Figure 10 In this system, water can be removed from the second pool area and reintroduced anywhere within the system. For example... Figure 11 As shown, water can move along the second pool area to be reintroduced into other areas of the pool, such as the transverse side of the first pool area.

[0067] Exemplary embodiments of the wave generating device may include a beach area 188 adjacent to a second pool area and / or a pool and / or other water features, where water may be inaccessible and spectators may gather. Other observation areas 189 may be provided along other sides of the wave generating device, such as on the lateral side of the pool area 181.

[0068] Therefore, exemplary embodiments may include a pool configuration in which wave energy flows into a second pool area at a height corresponding to a desired water level (such as a low water level). The second pool area may be a deeper accumulator or tank. One or more second pool areas may be configured to absorb and dissipate water flow from the main pool or the pool used to generate waves. In exemplary embodiments, the main pool and the secondary pool may be fluidly connected via deep water channels, thereby maintaining the water levels in the main pool and the secondary pool at equal heights without the need for buffer tanks or pumps.

[0069] Figure 9An optional pool configuration is shown having a first pool area 191 and a second pool area 193 to dissipate energy created by the waves 192. The main or first pool area 191 can include a low water line and a high water line as the waves are created and dissipate along the beach area 195. A desired water line 194 can be selected where the first pool area 191 and the second pool area 193 can be in fluid communication. The desired water line 194 can be located at the low water line, below the low water line, or between the low water line and the high water line, or a combination thereof along the length of the beach area. The desired water line 194 can correspond to the highest elevation of the pool floor at a point between the first pool area and the second pool area. Similar to the description of Figure 8 the gap 196 can be formed between a portion of the first pool area 191 and the second pool area 193 along the length of the beach area.

[0070] Figure 9 Embodiments of the present disclosure can create a larger pool area of accumulation at the opposite ends of the beach area adjacent to the lateral sides of the main pool 191. Thus, the second pool area can include a slope that extends into the main pool area 191. The second pool area 193 can then create a passageway toward the center of the wave generating device to re-enter the main pool area at a location in the middle of the beach area.

[0071] In exemplary embodiments, the wave generating device can include a deep water return channel 197. The deep water return channel 197 can fluidly connect one or more second pools 193 with the main pool 191 of the beach area 195 away from the main pool. As shown, the deep water return channel 197 extends under the beach area 195 of the first pool 191 to fluidly connect to the pool floor adjacent to or closer to the chamber than the beach area of the first pool 191.

[0072] Thus, exemplary embodiments can include a wave generating device having a first pool and one or more second pools. The first pool and the one or more second pools can be configured such that wave energy from the first pool washes over a desired water line or level and into the one or more second pools. As shown, two second pools can be used on opposite ends of the beach area of the first pool. The second pool areas can then be deepened and provide a water level and return channel that can absorb and dissipate the water flow from the main pool. In exemplary embodiments, water can return thereto.

[0073] Figure 10An optional pool configuration is shown having a first pool area 111 and a second pool area 113 to dissipate energy created by the wave 112. The main or first pool area 111 can include a low water line (L) and a high water line (H) as the wave is created and dissipates along the beach area 115. A desired water line 114 can be selected where the first pool area 111 and the second pool area 113 can be in fluid communication. The desired water line 114 can be located at the low water line, below the low water line, or between the low water line and the high water line, or a combination thereof along the length of the beach area. The desired water line 114 can correspond to the highest elevation of the pool floor at a point between the first pool area and the second pool area. Similar to the description of Figure 8 the gap 116 can be formed between a portion of the first pool area 111 and the second pool area 113 along the length of the beach area.

[0074] In Figure 10 exemplary embodiments, water from the one or more second pools can be removed from the wave generating device and / or the main pool 111. In this case, the water can be directed to a catch basin or other water feature such as a lazy river or wading pool. In exemplary embodiments, the other body of water can have a lower static water level to allow water to drain from the one or more second pools and / or the channel created thereby and into the other body of water. In one exemplary embodiment, water from the other body of water can be pumped back into the main pool 111 and / or the chamber 14. The flow rate and pump inlet location can vary depending on the pool configuration and / or other water feature.

[0075] In exemplary embodiments, the second pool area(s) 113 can be covered. The second pool area includes a deeper channel that can capture water as it spills from the main pool 111 during a wave. The second pool area(s) can be covered by a porous ground surface such that water can pass therethrough, but patrons can walk on top of the second pool area. Thus, all or a portion of the second pool area can not be used as part of the activity area of the water park attraction. Instead, the second pool area(s) can be located underneath the beach area.

[0076] Exemplary embodiments provided herein include a wave generating device where wave energy can be channeled over a static water level divider and into one or more second pool areas. Thus, the water flow can be drained to a catch basin or other water feature at a lower static water level than the main pool. Thereafter, the water can be pumped from the pool or feature back into the pool to maintain an operational water level.

[0077] Figure 11An alternative pool configuration is shown with a first pool area 1111 and a second pool area 1113 to dissipate energy created by waves 1112. The main or first pool area 1111 can include a low water line (L) and a high water line (H) as waves are created and dissipate along a beach area 1115. A desired water line 1114 can be selected where the first pool area 1111 and the second pool area 1113 can be in fluid communication. The desired water line 1114 can be located at the low water line, below the low water line, or between the low water line and the high water line, or a combination thereof along the length of the beach area. The desired water line 1114 can correspond to the highest elevation of the pool floor at a point between the first pool area and the second pool area. In the example embodiment, the desired water line 1114 is located at or below the low water line for a portion of the length of the beach area and approximately equal to the high water line for another portion of the length of the beach area. In example embodiments, the desired water line can be located at the low water line and / or between the low water line and the high water line along the entire length of the beach area such that no gap is created between the first and second pools or only a temporary gap is created between the first and second pools during wave generation.

[0078] As shown by the arrows, water flow in the one or more second pools can be directed toward the opposite lateral end of the beach area of the lateral side of the main pool 1111. The second pool 1113 can extend along the lateral side of the pool 1111 and can be in fluid communication with the first pool 1111. In example embodiments, the bottom of the main pool 1111, or along the lower edge of the lateral side wall and / or through the pool floor of the pool 1111, can include a grate or holes to fluidly connect to the second pool(s) 1113. Water can flow back to the first pool 1111 through the lower portion or bottom of the first pool 1111. Figure 11

[0079] Example embodiments described herein can include a wave generating device where wave energy can be channeled over a partition at a desired water level and into a secondary pool. The secondary pool can include a passageway with a covering. The covering can allow water to pass through the covering but not a person or body part. In example embodiments, the covering can conceal the passageway within the beach area of the first pool. In example embodiments, the water flow in the passageway can be reduced. The passageway and the first pool can be fluidly connected through an opening in the pool floor allowing the two bodies of water to maintain the same water level without pumping. Users and patrons can also cross over the covering of the passageway.

[0080] ​Exemplary configurations of systems and methods for dissipating wave energy and controlling water flow in a main pool are provided herein. Illustrative combinations are provided by way of example only. Any exemplary feature can be used with any combination of other exemplary features. For example, any representative example can include a shallow open pool that can act as a wading or puddling pool for the second pool(s). Any representative example can include a passageway with a covering such that the second pool does not create an active portion. Any representative example can include a deep water return passageway for connecting the second pool to the floor of the first pool. Any representative example can include one or more pumps to help fluid flow and move water in a desired direction. Any representative example can have the first pool(s) and the second pool(s) in fluid communication throughout wave generation. Any representative example can have a desired water line of any configuration that separates the top of the first pool from the top of the second pool to allow water from the first pool to overflow the desired water line and into the second pool(s). For example, any representative example can position the desired water line below the low water line, approximately equal to the low water line, between the low water line and the high water line, or above the high water line along the length between the first pool and the one or more second pools, or any combination thereof.

[0081] Exemplary embodiments described herein can include a pool wave generator having a pool area and a plurality of chambers on a side of the pool area for releasing water into the pool area to create waves in the pool area. The pool area can include a first linear wall and the plurality of chambers are configured to release water into the pool area along an entire length of the first linear wall. The pool area can also include two lateral side walls that extend from ends of the first linear wall at an oblique angle.

[0082] Exemplary embodiments can also include a pool wave generator having a pool area and any method of generating waves to propagate across the pool area. The pool wave generator can also include one or more second pool areas. The first pool area and the second pool area can be separated by a partition having a height at a desired water level. The height of the partition can vary between the first pool area and the second pool area along a length of the partition. The height of the partition can be at a low water height of the pool area during wave generation, at a still water height of the pool area when waves are not being generated, at or above a low water height of the pool area during wave generation, below a high water height of the pool area during wave generation, and combinations thereof.

[0083] The second pool can be positioned to cross the pool area from the chambers. The second pool can be configured to form a passageway for water to travel laterally across a length of the pool area and minimize an amount of water that is backflowed into the pool after a wave at an exit location of the water from the pool area. The second pool can be positioned to receive water exiting the pool area during a wave to minimize direct backflow of water into the pool area.

[0084] The second pool can be in fluid communication with the first pool area through a deep channel located underneath the pool floor of the first pool area.

[0085] Water received in the second pool can be transferred to another water structure. For example, the other water structure can be a separate water play area, such as a wading pool, a pool, a lazy river, or a combination thereof.

[0086] The second pool can include a channel. The channel can be configured to extend around a lateral side of the pool area. The channel can be configured to reintroduce water from the channel into the pool area at a bottom of the pool area.

[0087] The second pool can be covered, wherein the covering includes perforations to allow fluid to flow therethrough, but prevent body parts from passing through the covering.

[0088] Figure 12 A portion of an example pool floor bottom is shown similar to Figure 4 As shown, the pool floor can include a backflow channel 1201 located in the center of the pool. As described herein, the backflow channel can be a pool floor contour to facilitate water flow movement from a first pool and / or a second pool. For example, the example pool floor can include a continuous tapered region to allow the backflow to transition back into the pool horizontally. The backflow channel 1201 can facilitate a phenomenon similar to a vortex. All or a portion of the backflow channel 1201 can be at a lower elevation of the pool floor relative to the opposing lateral sides of the backflow channel at one or more locations and / or lengths.

[0089] Figures 13-19 Example features for managing water flow using different configurations of backflow channels as described herein are shown according to example embodiments. These example embodiments are illustrative only. Different components and configurations can be used in different combinations, and any feature, such as shape, location, and / or creation of a channel using one or more walls, notches, or as otherwise described herein, can be used in any combination. The example embodiments of combinations selected are illustrative only. The example embodiments of backflow channels described herein can be used with any wave generating pool. As shown, the wave generating pool can have a pool area 1304 with a plurality of chambers 1302 disposed at one end thereof. The chambers 1302 can release water at the pool floor of the pool 1304 through openings 1306. The pool area 1304 can have a deep end proximate the chambers 1302, and can have a shallow end at an end of the pool distal from the chambers. The pool floor can slope upward from the deep end toward the shallow end and / or can have portions of constant depth as described herein. As shown, the openings 1306 are located forward and spaced apart from the front wall of the chambers 1302 by a gap, thereby creating a channel from the chambers to the openings.

[0090] Figure 13 An exemplary embodiment is shown using a shore-side channel and a side channel with a reverse circulation channel. This configuration can include a reverse circulation channel behind a side sloped wall. This configuration can also achieve full circulation by including a reverse circulation channel in the gap between the front wall of the chamber and the back wall of the pool. This configuration combines multiple exemplary configurations including multiple recirculation channels with specific designs.

[0091] As shown, the pool 1304 includes a shore-side recirculation channel 1308. The shore-side recirculation channel 1308 can be a portion of the shallow end of the pool floor that includes a deeper channel that captures water as it is pushed up the shore by the waves to reduce the amount of water that subsequently recirculates into the pool that can create eddies. The shore-side recirculation channel 1308 can be located, proximate to, and / or adjacent to (on the water side or dry shore side of the pool) the calm water level of the pool. Thus, the shore-side recirculation channel can be configured to capture a majority of the water before it recirculates into the pool in the direction from the shallow end of the pool to the deep end of the pool.

[0092] As shown, the shore-side recirculation channel 1308 can be fluidly connected with a side recirculation channel 1310. As shown, the shore-side recirculation channel 1308 can extend outward from the shallow end of the pool toward the side edge and directly connect and extend into the side recirculation channel 1310. The side recirculation channel can be positioned between the sloped side wall 1314 of the pool and the outer side wall 1312. The channel can have a variable pool floor depth (such as becoming deeper toward the chamber) or can have a constant depth.

[0093] As shown, the side recirculation channel 1310 can extend into and be in fluid communication with a reverse circulation channel 1318. The reverse circulation channel 1318 can be a passageway between the back wall of the pool 1322 and the front wall 1322 of the chamber 1302 proximate to the opening 1306 that allows water to enter the pool 1304 from the chamber 1302. As described herein, the chamber and pool can include a gap in order to allow the passageway between the chamber 1302 and the opening 1306 to extend for fluid flow management. The reverse circulation channel can utilize the space created by the gap and located above the channel. As shown, the reverse circulation channel can be isolated from the passageway, opening, chamber, and / or pool. The reverse circulation channel can be in fluid communication with the side recirculation channel.

[0094] As shown, the return flow channel can be in fluid communication with the pool 1304. As shown, the return flow channel can include an opening(s) 1316 between the one or more return flow channels and the pool. As shown, the opening 1316 is on the inner wall of the side channel 1310 in the sloped side wall of the pool 1314. The opening can be at the end of the sloped side wall 1314 at the deep end of the pool, proximate to the chamber 1302. The opening can be in the side wall proximate to the pool floor such that water returns to the pool below the water level of the pool. The opening can extend up the wall to a height that is less than the static water level, less than or equal to three-fourths of the static water level, less than or equal to half of the static water level, or to another predetermined height in the wall.

[0095] Figure 14 The configuration is an example embodiment that uses a side channel. This configuration uses a larger buffer tank type design behind the sloped wall. This configuration does not include a reverse circulation channel, so a full circulation channel is not formed in this configuration. This configuration also provides a walkway along the side of the pool that is above or proximate to the one or more channels and / or a portion of the pool.

[0096] As shown, the pool 1304 includes a shore return flow channel 1408. The shore return flow channel 1408 can be a portion of the shallow end of the pool floor that includes a deeper channel that captures water as it is pushed up the shore by waves to reduce the amount of water that subsequently returns to the pool that can create eddies. The shore return flow channel 1408 can be located, proximate to, and / or adjacent to (on either the water side or the dry shore side of the pool) the static water level of the pool. Thus, the shore return flow channel can be configured to capture a majority of the water before it returns to the pool in a direction from the shallow end of the pool toward the deep end of the pool. The shore return flow channel 1408 can have a variable depth such that the shore return flow channel 1408 is deeper proximate to the side of the pool. Thus, the shore return flow channel can be shaped or configured to move water from the front of the pool to the side of the pool to the side return flow channel 1410.

[0097] As shown, the shore return flow channel 1408 can be fluidly connected to the side return flow channel 1410. As shown, the shore return flow channel 1408 can extend outward from the shallow end of the pool toward the side edge and directly connect and extend into the side return flow channel 1410. The side return flow channel can be between the sloped side wall 1414 and the outer side wall 1412 of the pool. The channel can have a variable floor depth (such as becoming deeper toward the chamber) or can have a constant depth. In contrast to the shore return flow channel 1408, the side return flow channel 1410 can have a greater width by creating a greater separation between the sloped side wall 1414 and the outer side wall 1412. The side return flow channel 1410 can extend behind the pool 1304, overlapping all or a portion of the chamber side. Figure 13 In contrast to the shore return flow channel 1408, the side return flow channel 1410 can have a greater width by creating a greater separation between the sloped side wall 1414 and the outer side wall 1412. The side return flow channel 1410 can extend behind the pool 1304, overlapping all or a portion of the chamber side.

[0098] The illustrated return flow channels can be in fluid communication with the pool 1304. As illustrated, the return flow channels can include a plurality of openings 1416 between one or more of the return flow channels and the pool. As illustrated, the openings 1416 are located on the interior wall of the side channel 1410 in the sloped side wall of the pool 1414. The openings can include a covering, such as a door, such that one, more, or any combination of the openings 1416 can be closed, or their opening size can be changed or manipulated.

[0099] As illustrated, the side return flow channels 1310 can terminate at the end of the chamber. Thus, this configuration can not include a reverse circulation channel 1318. The chamber 1420 can be fully enclosed as illustrated. The pool can also include a walkway 1418 along one side of the pool 1304 from the shore. The walkway can extend in the gap between the front wall of the chamber and the back wall of the pool. As illustrated, the walkway 1418 can extend over a portion of one or more of the return flow channels, such as the shore return flow channel, the side return flow channel, the reverse circulation channel, or a combination thereof. As illustrated, the walkway 1418 extends over the location of the shore return flow channel 1408 and between the pool and the side return flow channel. The openings between the side return flow channel 1410 and the pool 1304 extend under the walkway 1418.

[0100] Figure 15 The configuration of FIG. 15 is an example embodiment that uses side channels. This configuration provides another example embodiment of a larger buffer tank that can be located behind the sloped side wall. This configuration uses a full circulation channel in the gap between the chamber(s) and the pool.

[0101] Similar to the other configurations, this embodiment uses a side return flow channel 1510. The side return flow channel 1510 can be formed between the pool side wall 1514 and the exterior side wall 1512. As illustrated, the exterior side wall 1512 is sloped at a different angle than the pool side wall, thereby forming a wedge-shaped side return flow channel 1510. This configuration results in a larger buffer tank. The side return flow channel 1510 can have a variable depth and / or can have a constant depth. Similar to the configuration of FIG. 14, Figure 13 Similar to the configuration of FIG. 14, the side return flow channel 1510 is in fluid communication with a reverse circulation channel 1518. This reverse circulation channel can be located between the chamber(s) 1302 and the back wall of the pool and the opening(s) 1306 into the chamber of the pool. As illustrated, this reverse circulation channel can be covered.

[0102] Figure 15Exemplary embodiments shown in FIGS. 15A and 15B show different shapes and configurations of the side return channel 1508. The side return channel 1508 can extend from only one side of the pool and can extend toward the deeper portion of the pool. The side return channel does not have to extend or traverse the entire length of the side of the pool. As shown, the side return channel is positioned in an area of the pool that is on the lateral side of the pool, but not directly in front of the chamber. As shown, the portion of the pool in front of the chamber can be the portion of the pool that is in contact with the wall that forms the front of the chamber and the portion of the pool that extends perpendicular to that wall. The area of the pool on the side of the pool that is not in front of the chamber and toward the sloped side wall can include the side return channel. The side return channel 1508 can extend from the pool side wall 1514 or traverse the side of the pool for a length. The side return channel 1508 can turn inward and extend along a length that is toward the chamber(s), toward the deeper end of the pool, and / or generally parallel to a portion of the pool side wall 1514, the outer side wall 1512, or other measure of the side return channel 1510.

[0103] Figure 16 An exemplary embodiment is shown where the side channel is formed as a continuation of the pool depth gauge behind the sloped wall, with a circulation channel in the gap between the chamber and the pool. The exemplary embodiment utilizes a medium size sloped wall.

[0104] In this configuration, a side return channel 1610 is formed between the outer side wall 1612 and the pool side wall 1614. The pool side wall 1614 can extend along a portion of the pool side, such that the entire pool side traverses the pool side wall 1614 and a portion of the outer side wall 1612. The length of the pool side wall 1614 can be less than or equal to the length of the outer side wall 1612. As shown, the length of the pool side wall 1614 can be about half the length of the pool side wall. The pool side wall 1614 can be between 25% and 75% of the outer side wall 1612. The pool side wall can extend to a height above the static water height and / or the moving water height of the pool to form a barrier along the length of the pool side wall 1614 between the pool and the outer side wall 1612. The pool can be in fluid communication with the side return channel 1610 in the area where the pool side wall terminates and the pool is in direct contact with the outer side wall 1612. The end of the side return channel can open to a portion of the pool.

[0105] Figure 17 An exemplary embodiment is shown that uses a side channel in combination with a side return channel and a pool return channel. In this configuration, the pool return channel is fluidly coupled to the side return channel. This exemplary configuration also includes a side return channel that is a continuation of the pool depth gauge behind the sloped wall. This configuration also includes a circulation channel in the gap between the chamber and the pool. This configuration includes a medium size sloped wall.

[0106] Exemplary embodiments can include a shore return channel 1708. The shore return channel 1708 can traverse or extend across the entire length of the shore. The shore return channel 1708 can be covered (not shown), such as with a grate system or other covering to allow water flow through. The shore return channel 1708 can be formed as a channel in the pool floor that extends deeper in the pool floor to form a discontinuous notch in the pool floor. The channel can also be a gradual depth change, creating a continuous depth change. Thus, the channel can be defined as a deeper portion of the pool in a shallow area of the pool, or have a shallow pool floor on opposite sides of the channel.

[0107] Exemplary embodiments can include a pool return channel 1728. The pool return channel can be a channel in the pool floor, similar to the shore return channel. The return channel can be defined by a portion of the pool floor that is deeper than portions of the pool floor located on one or both sides of the channel. The pool return channel 1728 can extend from the shore and / or from a portion of the shore return channel 1708 toward the chamber(s) and / or toward the deeper end of the pool. As shown, the pool return channel extends perpendicularly from the front wall of the chamber(s) and is located approximately in the middle of the pool, around the axis of symmetry of the pool. If the pool does not include two lobes, the pool return channel can be on or toward one side of the pool, or if the pool includes more than two lobes, the pool return channel can be offset from the center of symmetry. The pool return channel can extend from a shallower portion of the pool and have a depth approximately equal to the deepest portion of the pool. The pool return channel can extend from a shallower portion of the pool to the opening 1306 in the pool floor of the chamber. The pool return channel can extend from a shallower portion of the pool toward the deeper end of the pool, but can terminate before the opening 1306 in the pool floor that is in fluid communication with the chamber.

[0108] Exemplary embodiments can also include a combination of the shore return channel and a partial side wall configuration defining the side return channel. In this configuration, the side return channel 1710 can be defined between the pool side wall 1714 and the outer side wall 1712, similar to the side return channel described in U.S. Patent No. 6, 1 12, 476. The shore return channel 1708 can be in fluid communication with the side return channel 1710 through the pool itself. Thus, the shore return channel 1708 can be discontinuous with the side return channel 1710. Thus, the flow of water can be controlled through the respective return channels. For example, water captured in the shore return channel 1708 can pass over the shore and be returned to the pool through the pool return channel 1728. Overflow water or other returned water can be captured in the side return channel 1710, rather than in the shore return channel. The side return channel 1710 can circulate water through the reverse circulation channel 1718. Figure 16

[0109] Figure 18 ​is a configuration in which the side channels are a continuation of the back wall of the pool depth finder. This configuration does not include a pool return channel, but has a circulation channel underneath the mechanical chamber, and also utilizes a shortened back wall.

[0110] As shown, the pool can include side return channels 1810. The side return channels can be formed between the pool side walls 1814 and the outer side walls 1812. Similar to Figure 14 the side channels of Figure 15 , the separation distance between the pool side walls 1814 and the outer side walls 1512 can be widened so as to overlap a portion or all of the sides of the chamber. Other shapes and configurations of the respective side walls are also contemplated herein. For example, Figures 16-18 wedge shapes can also be incorporated into embodiments similar to

[0111] Exemplary embodiments of the side return channels 1810 can be in direct fluid communication with a reverse circulation channel 1818. The reverse circulation channel 1818 can allow fluid to circulate between the back walls of the pool. The reverse circulation channel can be configured to allow fluid to flow under a portion of the chamber, under a portion of a structure associated with the chamber (such as an air chamber, a mechanical chamber, etc.), within a gap between the back of the pool and the chamber, behind the chamber, behind a passageway between the chamber and the pool, and / or behind the chamber. As shown, the reverse circulation channel 1818 can be located underneath a mechanical chamber associated with the chamber, as described in more detail with respect to Figure 7 .

[0112] Any of the return and / or circulation channels described herein can be covered. For example, the space defining the channel can include a grate including openings that allow water to flow therethrough and / or can include a solid material. Exemplary embodiments can include channel portions having solid coverings, while other portions have grate coverings. Thus, access to the channel can be controlled and / or limited to select locations within the pool. Exemplary embodiments can include coverings to reduce the chance of debris and / or a user's body parts and / or clothing from entering the channel. Exemplary embodiments can include other configurations of the channels described herein. For example, the channel can be formed through a pipe within or underneath the pool floor structure. Access to the channel can be through one or more holes between the channel and the pool floor (including the shore) and / or the pool walls.

[0113] Figure 19 is a configuration in which the shore channel 1908 is in communication with a covered pool return channel 1928. This configuration does not include a side return channel, but can in fact include any of the side return channels described herein. Figure 19Also included are undulating inlets into the shore return channel for controlling / selecting water into the shore return channel 1908. The shore return channel can include grates along the entire shore return channel. The shore return channel can include grates only at portions of the shore return channel, such as those corresponding to the pool floor profile on the laterally outer edges of the pool, the shore area on the opposite end of the area of the pool from the area opposite the chamber extending beyond the end of the chamber in the lateral direction (parallel to the front wall of the chamber).

[0114] Exemplary embodiments can include a pool 1304 with a shaped pool floor. The shaped pool floor can be similar to the pool floor described with respect to Figure 15 The shore return channel 1908 can also extend toward the middle of the shore and across the entire shore of the pool in this configuration. The shaped pool floor can include a portion with an inclined pool floor 1911 that extends upward from the deeper end of the pool (toward the chamber) to the shallow or shore end of the pool (toward the shore). The portion of the inclined pool floor 1911 can include areas of lesser inclination or no inclination, creating notches 1909 in the raised inclined pool floor. The notches 1909 can assist or control the water bottom in the pool. As described with respect to Figure 15 The notches 1909 can be located on the outward lateral end areas of the pool. The notches 1909 can be in the area of the shore beyond the area directly in front of the chamber. The notches 1909 can be in the shore area in the portion of the pool beyond the chamber end. The notches 1909 can have upwardly inclined pool floor 1911 areas on both sides of the notches, and / or the notches 1909 can go directly upward against the pool wall or edge.

[0115] Exemplary embodiments can include a pool return channel 1928 in fluid communication with the shore return channel 1908. As shown, the pool return channel is covered and includes a first opening 1930 to allow water to flow from the shore return channel into the pool return channel. The pool return channel 1928 can also include a second opening 1932 in the pool floor (or pool wall, if the return channel extends to or is part of the pool wall). The return channel can include a pipe or other structure that can be embedded or located under the pool floor. As shown, a portion of the return channel can be completely enclosed with a solid covering, while other portions of the channel can include openings to allow water to pass therethrough and be in fluid communication with the pool.

[0116] When examining the water flow pattern within the pool, the example embodiments show water backflowing into the pool (and feeding more water flow) before reaching the shore return channel. Water backflow can occur because water naturally travels along the easiest path (the path of least resistance). Due to the nature of wave generation, the order of the chambers is to create small water flow along the walls, such that the path along the walls is the easiest path to follow. Thus, the example embodiments can use side backflow channels as described herein. Thus, the example embodiments can terminate the pool sidewall at the area where water backflows into the pool.

[0117] The example embodiments can also include pumps, turbines, baffles, or other water control devices to force water to move into one or more backflow channels. The use of water control devices can affect the water flow path and redefine the easiest path for water to follow (backflow channels instead of the path along the walls).

[0118] Thus, the example embodiments can include any combination of pumps, turbines, baffles, or other water control devices in one or more backflow channels or in the space adjacent to one or more backflow channels in fluid communication with the pool. Thus, water from the pool can be directed by the backflow channels instead of along the walls. The example embodiments can include fluid flow speed control so that the user can control the speed in the channels. Thus, the example embodiments can provide additional control over the water flow in the pool.

[0119] As described herein, the example embodiments can include any combination of:

[0120] Using the openings of the side backflow channels located on each side of the pool to capture the maximum amount of energy,

[0121] Returning to the backflow channels behind the pool's sloped sidewalls,

[0122] Backflow side channels connected between the chambers and the pool or behind the mechanical chamber or at other locations to form backflow circulation channels,

[0123] Turbines and / or pumps added to the backflow channels to form new paths of least resistance to the fluid flow,

[0124] The turbines and / or pumps can be controlled so that they do not need to be on all the time, but can be selectively turned on in order to initiate the flow circulation,

[0125] A controller to allow variable speed in the backflow channels to adjust the water flow according to wave size, wave frequency, number of waves in a set, wave type,

[0126] Using filtration devices to force water in the channels,

[0127] using existing lazy river, standing wave, or waterslide equipment, or any attraction with a pump to power the return flow channel,

[0128] and any combination thereof.
