Description

BACKGROUND

[0001] Water attractions have provided enjoyment for generations of people from diverse geographical locations. They allow people from different regions to access simulated experiences from other areas. For example, a wave pool can approximate the experience of being at a beach.

[0002] Various water attractions can be used to approximate natural environments, allowing users to experience sports and activities from those other settings. For example, sheet wave rides simulate a surfing or boogie-boarding experience, allowing a rider to ride a sheet flow of water contoured by an underlying riding surface using their body or a thin board. Sheet wave rides do not offer a true surfing experience, as the sheet flow does not allow for wave breaking or the use of an actual surfboard.

[0003] Deep wave surfing systems are provided that attempt to create a more accurate approximation of the surfing experience in its natural environment. US patents 8,434,966; 9,103,133; 9,279,263; 10,145,135; 10,280,640 and 10,526,806 disclose deep wave surfing simulators, each of which is incorporated herein by reference in its entirety. SUMMARY

[0004] A pool wave generator is disclosed, comprising a pool area and a multitude of chambers for generating a wave within the pool area. The multiple chambers can be used to retain or release water into the pool to create a desired wave.

[0005] The multiple chambers can be separated by an edge of the pool to create a gap between them. A passageway can be positioned below the gap to fluidically couple the chamber to the pool. The passageway can be used to reduce turbidity or limit eddy currents in the fluid when the water moves between the chamber and the pool. The gap can accommodate spectators or the housing of controls, blowers, pumps, or other components and / or equipment of the pool wave generator. In one exemplary embodiment, the gap can include a floor to support a spectator. The gap can also include an edge corresponding to an extension of an edge of the pool. The edge of the gap can include a transparent wall to allow observation of the pool activity from a point within the gap.

[0006] The pool wave generator can also include a pool floor and / or a pool edge to influence a wave profile or wave characteristics and / or to generate different wave zones. The pool floor can include different combinations of tapered sections and / or horizontal sections or other contours to generate different breaking waves with varying properties.

[0007] The pool wave generator can also include outward-flaring walls extending away from the multiple chambers. These wall positions can be used to reduce and / or control eddy currents generated by the interaction of the water with the wall and / or the floor.

[0008] The following detailed description illustrates the principles of the invention by way of example and without limitation. This description will enable a person skilled in the art to reproduce and use the invention unambiguously and describes several embodiments, adaptations, variations, alternatives, and uses of the invention, including what is currently considered the best way of carrying out the invention. It is understood that the drawings are diagrammatic and schematic representations of exemplary embodiments of the invention and do not limit the present invention, nor are they necessarily drawn to scale.

[0009] Exemplary embodiments described herein include a pool configured to generate waves. The pool may include one or more chambers at one end configured to receive water and release it into the pool to create the waves. Exemplary chambers are provided to reduce turbulence and create better waves for riding. The pool may be configured to create zones that define or generate waves of different profiles and / or for riding by riders of varying experience levels.

[0010] Although embodiments of the invention relating to a pool wave generator with unique and novel features may be described and illustrated herein, it is understood that embodiments of this invention do not require or necessitate the inclusion of every single feature. The present disclosure does not require any specific component, configuration, or feature, and any combination of features may be included or combined and remain within the complete description of the invention. For example, the inclusion of the elongated chamber between the chamber and the pool for reducing eddy currents can be used in all conventional features of a pool wave generator. Likewise, the inclusion of the spectator area and / or the base contour for generating different wave zones can be used equally well alone or in combination with other features described herein.

[0011] Fig. Figure 1A illustrates an exemplary wave pool according to embodiments of the invention. The exemplary pool wave generator 10 can include a pool area 12 and one or more chambers 14 for generating a wave within the pool area. The wave 16 can propagate away from the chamber(s) 14 and towards a terminal end 18 of the pool.

[0012] In one exemplary embodiment, the pool area 12 can be a sunken pool configured to retain water. The end 18 can be a wall for retaining the water. The wall can be vertical or inclined. In one exemplary embodiment, the end 18 is created by an inclined bottom of the pool to approximate or resemble a beach area. When water is pushed over the pool area 12 by the release of water from the chambers 14, the water can move toward the end 18 and travel over the inclined bottom and upward until it stops and eventually flows back down the inclined bottom to the pool area under the influence of gravity.

[0013] Fig. Figure 1A illustrates an exemplary pool wave generator comprising two sides in which a wave can propagate from the chambers to opposite ends of the pool. This can be used to create distinct areas that may exhibit similar or different wave profiles for use by different riders. The distinct areas can be used to generate waves for riders of varying experience levels. Exemplary embodiments include a pool wave generator in which a wave propagates in a single direction, as shown in Figure 1A. Fig. 1B illustrates.

[0014] As indicated by the arrows adjacent to chambers 14, the chambers 14 can release water sequentially into pool area 14. The chambers can be linearly aligned along one side of pool 12. The chambers can also have different directions, configurations, and orientations. The release of water from the chambers can be used to control wave attributes, such as wave height, direction, shape, etc. As shown in Fig. As illustrated in Figure 1A, chambers are released together in the direction of the center of the plurality of chambers, and then the chambers can release sequentially by moving outward toward 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 (as in Figure 1A). Fig. (1B illustrated) or from opposite ends towards the center of the multitude of chambers.

[0015] Fig. Figure 1A illustrates an exemplary embodiment in which a linear arrangement of chambers is provided along an edge of the pool area 12. The chambers can traverse the entire length of the pool edge. As illustrated, a lateral side of the pool wall 19, projecting immediately from the end of the last chamber at the pool edge, can extend at a non-zero angle measured from the linear extension of the pool edge defined by the chambers. In other words, the lateral wall can extend forward immediately from the end of the chamber. The lateral wall can also have a component extending outward in a continued extension of the linear direction of the chamber, forming a non-zero angle, not perpendicular to the linear extension of the pool edge encompassing the chambers.Angled pool walls on one lateral side of the pool can reduce the amount of water required to fill a pool and reduce areas of the pool that may produce less desirable wave effects.

[0016] Fig. Figure 1C illustrates an exemplary vector model of the velocity of the water and corresponding waves during wave generation of an exemplary wave pool generator according to the embodiments described herein. As illustrated, defined wave regions can be seen as the wave traverses the length of the pool. As illustrated by the dotted box in the center of the pool area, the pool may include a dead spot that can be used as a paddle channel and / or waiting area to enter the wave regions.

[0017] Angled lateral sides can also be used to control pool flows according to the embodiments described herein. Fig. Figure 1D illustrates an example wave velocity map of a pool configured with an extension wall at opposite ends, such that the side of the pool containing the chambers has a linear continuation of the wall beyond the chambers. As illustrated, the pool experiences significant backflows toward the flat wall. This creates a vortex at the end of the chambers, which can disrupt wave propagation. Fig. Figure 1E illustrates an exemplary wave velocity map with a pool having angled walls according to embodiments described herein. Unexpectedly, the distance of the water flow path back to the chambers reduces the resulting whirlpool at the end of the chambers. It is assumed that the angled wall focuses the remaining wave energy, which can then be used to generate an intermediate wave-riding area according to embodiments described herein. The wave velocity map illustrates the speed of water during wave generation, with the arrow representing the direction and quantity (a larger arrow represents a greater speed or faster wave).

[0018] Exemplary embodiments described herein may include a pool with a first linear edge in which a plurality of chambers are configured to fluidically couple water along the first linear edge and discharge it into the pool. One or more chambers may be configured along an entirety of the first linear edge. The pool may include two opposite lateral sides extending from the endpoints of the first linear edge. The opposite lateral sides may extend at an angle forward of the first linear edge. The angle of each lateral side may be the same or different, depending on the pool configuration. The opposite lateral sides may extend outward and forward at an oblique angle from the first linear edge. Exemplary embodiments of the angled opposite lateral sides may contribute to flow attenuation.Exemplary embodiments of the angled opposite lateral sides can also focus the energy of a wave, allowing a wave to be regenerated for different experience levels. Exemplary embodiments include an oblique angle measured from the front of the linear position of chambers outward around the pool area and to the linear side wall. The oblique angle is preferably greater than 90 degrees and less than 180 degrees. The oblique angle can also be greater than 110 degrees, greater than 120 degrees, greater than or approximately 135 degrees, greater than or approximately 150 degrees, or greater than or approximately 160 degrees. The oblique angle can also or additionally be less than 180 degrees, less than 170 degrees, less than or equal to 160 degrees, less than or equal to 150 degrees, or less than or equal to 135 degrees.

[0019] Fig. Figures 2A-2C illustrate an exemplary wave-generating chamber and associated control system for generating a wave in the wave pool described herein. The chamber 20 can be configured to retain water at a chamber water level 28, which, when released into the pool, raises the pool water level 26, thereby generating a wave 26' that propagates from the chamber 20 across the pool. The chamber can include one or more valves 22, 24 for controlling the retention and release of water in the chamber. In one exemplary embodiment, a first valve 22 can control the flow of water into and out of the chamber 20. In another exemplary embodiment, a second valve 24 can control the flow of air or fluid into and out of the chamber 20.The second valve 24 can be used to introduce pressurized gas into the chamber and / or to release gas from the chamber to assist the movement of water into and out of the chamber. The second valve 24 can include one or more valves to control the inflow and outflow of gas from the chamber 20.

[0020] As in Fig. If 2A is visible, the system may have been released, so that there is no water in chamber 20 or the water level 28 in chamber is at a low level (as in Fig. (2C illustrated). The second valve 24 can be opened to purge air from the chamber. The chamber can be configured to evacuate air from chamber 20, so that the chamber is under negative pressure. The vent 24 can also be open, so that chamber 20 is at neutral pressure and the air in the chamber can be released when the chamber is filled with water. The first valve 22 is opened and the surge of water into the chamber increases the water level in the chamber.

[0021] As in Fig. As shown in Figure 2B, the first valve 22 is closed to maintain the chamber water level 28 at a height higher than the pool water level 26. The chamber can then be filled with pressurized gas to exert additional pressure on the water in the chamber. The second valve 24 is then closed, and the first valve is then opened.

[0022] As in Fig. As can be seen in Figure 2C, the compressed air in the chamber pushes the water level 28 in the chamber, which in turn pumps water out of the chamber to create a wave 26' that propagates across the pool. The first valve 22 can be closed while the air in the chamber is being released, as for example by the second valve 24. The first valve 22 can be closed to limit the amount of water returning to the chamber to minimize disturbance of the formed wave 26'. The first valve 22 can also remain open to allow the water to return to the chamber and be closed, as shown in Figure 2C. Fig. 2B discussed.

[0023] In one exemplary embodiment, the system is configured to perform the process of releasing water from the chamber and allowing water to rise 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 could affect wave generation.

[0024] In the exemplary embodiment provided herein, two valves are illustrated—a first valve 22 for water control and a second valve 24 for gas control. Any combination of valves can be used and is within the scope of this disclosure. For example, multiple gas valves can be used to drain the chamber, inject pressurized gas, etc., and multiple fluid valves can be used to release or retain water in the chamber. The sequence and / or cycle of the valves as described herein is only exemplary. Any number of different ways can be used to release the shaft using valves, gates, or other methods. The valves can be opened and closed in various ways.For example, the system can use a purge system to remove gas from the chamber before water re-enters, thus increasing the water level returning to the chamber. For example, the system cannot use a pressurized gas system to expel water into the pool. For example, one-way valves can be used, so that valves do not require individual actuation to open and close each one. The valves in each chamber can be controlled individually or as a sequence within a larger operation of the entire pool system.

[0025] Fig. Figure 3 illustrates an exemplary wave pool 30 for generating different zones with different wave characteristics according to embodiments of the invention. In one exemplary embodiment, the pool profile 32 and the pool bottom 34 can be contoured to define a desired wave profile and / or to generate multiple wave zones 36, 37 and 38.

[0026] In an exemplary embodiment, multiple wave zones 36, 37, 38 can be generated. The generation of multiple wave zones can be achieved from a single wave generation cycle of the chambers. For example, the chambers can release sequentially to form an initial wave. This initial wave can change its profile, height, direction, etc., as it propagates across the pool floor. The wave can also deteriorate and / or reform based on the underlying topography of the pool floor. As, for example, in Fig. As illustrated in Figure 3, three wave zones are generated on one side of the pool for a single wave generation cycle. The pool can have a mirrored configuration, resulting in a total of six wave zones. However, three of the wave zones are independent of the other three, as a different wave or section of the wave generates the first three wave zones than the wave or section of the wave that generates the second three. Any combination of wave zones can be generated, and the combination of two sides of three for a total of six zones is only illustrative. In an exemplary embodiment, the wave pool can have only one, two, three, or more wave zones. The pool can have a mirrored configuration, as shown in Figure 3. Fig. 1A, which doubles the wave zones, or the pool can be a single side, as in Fig. 1B. The opposite sides of the pool can also be configured differently, so that different wave zones can be created across the entire pool.

[0027] As illustrated, a first wave zone 36 borders the wave-generating chambers. The wave is highest in this section. This area can be suitable for the most experienced riders. It can also be suitable for shortboard riders.

[0028] As illustrated, a second wave zone 37 can be located in an area of ​​the pool after the wave leaves the chambers, running along a side wall or edge of the pool. The wave will dissipate energy and reduce its height as it propagates away from the chambers. This area is therefore created for intermediate and longboard riders.

[0029] As illustrated, a third wave zone 38 can be located adjacent to the side of the pool, away from the chambers. The edge can correspond to a shoreline area 46' of the pool. This area can have a shallow depth and a sloping bottom. The third wave zone 38 can be for beginning wave riders. This area can also be used for boogie boards, foam boards, kayaks, or skimming boards. This area can also be used for bodyriding or wave jumping.

[0030] The pool floor may have areas that correspond to or influence wave zones. For example, a first area of ​​42' on the pool floor may generally correspond to the first wave zone 36, while a second area of ​​44' on the pool floor may generally correspond to the second wave zone 37, and a third area of ​​46' on the pool floor may generally correspond to the third wave zone 38. A fourth area of ​​44' and / or other areas may be used to create and separate the different wave zones and / or be used to regenerate waves as the wave propagates from the chambers. The different areas of the pool floor are described in terms of Fig. 4 discussed in more detail.

[0031] The different bottom zones can be used to influence the wave profile. For example, the depth of the bottom can affect wave size, while the slope of the bottom can affect wave shape. The first zone, 42 feet away from the chambers, can therefore create a wave zone 36 for the most experienced riders. This zone can be approximately 2-6 meters deep. This zone may have a bottom with a steeper slope or incline towards the land or the opposite side of the pool and / or may have the greatest depth. The third zone, 46 feet away from the land or the edge of the pool, can be adjacent to the land or the edge of the pool and can create a wave zone 38 for the most inexperienced riders. This zone may therefore have a bottom with the smallest slope or incline towards the edge and / or may have the shallowest depth. The gentler slope can make the wave breaking softer.

[0032] In one exemplary embodiment, the edge of the pool, away from the chambers, can also be contoured to influence wave characteristics. For example, in the third wave zone or beginner area, the edge toward the center of the pool, on a side of the pool opposite the middle chambers in the sequence of chambers, can be raised. This raised edge can form a land or a dry depression in the side of the pool. As the wave propagates across the pool from the chambers toward the land, it can wrap around the raised edge that extends into the pool area. Other or additional raised edges can be provided along the short section to create additional wave zones. In one exemplary embodiment, a raised edge can be used to split and / or redirect a wave.

[0033] With reference to Fig. 3. The land with two wave-generating sides can have a land configuration with two outer side lobes. The lobes can generally correspond to the third wave zone 38. The lobes can be shaped as a concave (with respect to an interior of the pool) edge section of the side of the pool opposite the chamber side of the pool. The lobes can be separated by an inner depression of the pool. The inner depression can be created by raising the pool bottom so that the width of the water contained in the pool is reduced between the land and the chambers at the inner depression and increased between the chambers and the land at the lobes. The inner depression can be configured as a convex (with respect to an interior of the pool) edge section of the side of the pool opposite the chamber side of the pool.Since the bottom of the pool may taper upwards on the land or side of the pool opposite the chambers, the "edge" of this side of the pool can be more difficult to determine. Therefore, in one embodiment, the edge can be considered the waterline of the pool when the water level is at rest without wave propagation. As in . Fig. As illustrated in Figure 3, the edge opposite the chambers, following the waterline, would therefore extend outwards away from the chambers, while the edge is traversed from the lateral side wall of the pool towards the center of the pool. Upon reaching a maximum width distance (perpendicular distance across the pool from the side containing the chambers to the point on the land edge), the land edge, or the edge opposite the chambers, then curves back towards the chambers, while the edge is traversed from its maximum width towards the center of the land edge. The interior of the land edge can include various contours, such as being generally linear, concave, and / or convex. This area may include a wading or small pool area. This area may also include an entry area for riders to access and exit the various wave zones.

[0034] As illustrated, the chambers can release water into the pool sequentially to generate a wave. If the chambers open first in the middle of the sequence and then sequentially in opposite directions toward each end, both left and right waves will propagate from the chambers and break at approximately the same time (assuming a mirror configuration of the pool). The chamber sequence can also be delayed or staggered, so the left and right breaking waves can be staggered. The expert wave zone can be defined as an area adjacent to or near the chambers. The wave within the expert wave zone can break along the wave-generating wall. The wave can maintain an approximately constant height because the sequential release of water from the chambers can be used to sustain the wave formation.In one exemplary embodiment, the wave height in the expert wave zone can be approximately 1.5 to 3.5 meters (approximately 4 to 11 feet). After the wave leaves the area near the chambers, it will dissipate energy, and the wave height will decrease. The wave, extending along the side edge of the pool away from the chambers, can form the intermediate wave zone, with a wave height reduced from that of the expert wave zone. In one exemplary embodiment, the wave height in the intermediate wave zone can be approximately 1 to 2 meters (approximately 3 to 6 feet). The wave height can continue to decrease as it moves away from the chambers. The wave can then break along the opposite side of the pool in the shallow area to create a beginner wave zone. In one exemplary embodiment, the wave height in the beginner wave zone can be approximately 0 to 1.5 meters (0 to 4.5 feet).

[0035] Fig. Figure 4 illustrates an exemplary basic profile that reflects the in Fig. 3 different wave zones of a pool wave system described corresponds to 40. Fig. 5A is an illustration of the exemplary basic profile of Fig. 4 with a reference line of 50. Fig. Figure 5B illustrates the cross-sectional perspective along reference line 50. Fig. 5A, to illustrate an example pool floor. As illustrated, the basic profile can include at least three areas.

[0036] In an exemplary embodiment, a first region 42 can correspond to the region near the chambers 14. As in Fig. As can be seen in Figure 5B, the pool bottom 52 of this area may have a gradual upward slope, such that the pool adjacent to the chamber is deeper than the pool on the opposite side of the area 42 from the chamber. The slope may traverse from deeper to shallower, moving across the area away from the chambers at an angle α. The first area 42 may generally be rectangular and extend directly in front of the chambers, as shown in Figure 5B. Fig. Figure 4 illustrates this. The first region 42 can also be widened at the ends, so that the region passes in front of the chambers and, while the region slopes away from the chambers, extends outwards beyond the ends of the chambers, as shown in Fig. Figure 3 illustrates this. Other forms of this area are also being considered.

[0037] In an exemplary embodiment, a third region 46 can correspond to the region at an opposite end of the pool that forms the chambers 14. The third region 46 can be located on a side of the pool corresponding to an end of the wave motion opposite the origin of the wave. The pool floor 56 of this region can have a more stepped slope than the slope of the region adjacent to the chambers. The pool floor 56 can include a stepped upward slope such that the pool is deeper towards the first region 42 than the region on an opposite side of it. The end of this region can have a depth of zero, so that the water washes up the side towards the surface of the wall. This region can approximate a beach area. The slope can traverse from deeper to shallower, moving across the region in a direction away from the chambers at an angle β.This area can correspond to a band or width at the termination end of the wave on a side of the pool opposite the chambers. Because the chambers can generate a wave that propagates away from the chambers at an oblique angle rather than directly perpendicular to a front face, the opposite end of the pool can be offset and include a section of the pool that terminates past the lateral side end of the chambers. "Opposite" can therefore refer to being directly or geometrically opposite, as well as opposite based on the propagation of the wave generated by the chambers.

[0038] As illustrated, the third area 46 can be shaped in a curve, such that sections of this area are farther from the chambers than other sections of this area. For example, the land area 46' can be curved so that sections adjacent to the lateral side of the pool, corresponding to the ends of the chambers, and toward the center of the land (for a mirrored pool) or the opposite lateral side of the pool (for a one-sided pool), are positioned closer to the chambers than areas in between.As illustrated, the land area or side of the pool opposite the chambers can therefore contain three curved regions: two outer regions at opposite ends of the land area, where the inward-facing concavity is concave towards the chambers, and an inner curved region between the two outer regions in the middle of the land area, where the outward-facing concavity is convex towards the chambers. The concave and / or convex land areas may include curved-linear sections. For example, the inner section of the concave or convex curved land area may extend to approximate a linear inner section, so that the curvature of the concave or convex section is not constant due to the curvature.

[0039] As illustrated, a second area 44 can extend from the first area 42 to the third area 46. This area can be similarly inclined. The slope of the area can be linear, curved-linear, or curved. This area can include a step-like slope that transitions the ground surface from the first area 42 to the third area 44. This area can also be contoured to provide a transition to any other area that may be included in the ground profile. The second area 44 can therefore provide a transition surface between two or more other ground surfaces or areas.

[0040] The pool may include one or more other bottom areas that define one or more other zones. For example, the first wave zone may be separated from the third wave zone. The separation may be to create a bottom profile to recreate a desired wave shape. The separation may be to provide space between the different wave zones for the safety and / or enjoyment of the riders. As in Fig. 3, Fig. 4 and Fig. As can be seen in Figure 5, a transition area 48, 48' can be used. The transition area 48, 48' can correspond to the ground surface 88, which is generally flat. The transition area can be positioned between the first area 42 and the third area 46 and / or the land area. As shown in Figure 5. Fig. As illustrated in Figure 3, the first region 42' can touch the third region 46' in a central section of the pool, while the transition section 48' separates the first region 42' from the third region 46' towards the outer lateral sides of the pool adjacent to the second region 44'. In an exemplary embodiment, as shown in Figure 3, the first region 42' can touch the third region 46' in a central section of the pool, while the transition section 48' separates the first region 42' from the third region 46' towards the outer lateral sides of the pool adjacent to the second region 44'. Fig. As illustrated in Figure 4, the transition area 48 can separate the first area 42 from the third area 46 along a length of the pool, such that the first area 42 does not touch the third area 46.

[0041] In one exemplary embodiment, the slope of the pool base 52, corresponding to a first region 42, 42', is greater than the slope of the pool base 56, corresponding to the third region 46, 46' (α > β). In another exemplary embodiment, the slope of the pool base of the second region 46, 46' is generally either equal to or between the slopes of the first region and the second region (α ≥ θ ≥ β). The pool base 52 can have a slope between 3 and 10 degrees. The pool base 56 can have a slope greater than 0 degrees up to 5 degrees. The pool base corresponding to the second region 46, 46' can have a slope between 2 and 10 degrees.

[0042] The configuration, shape, elevation, slopes, and other features of the pool floor described here are only examples. Other or additional features can be added and are within the scope of this description. For example, an additional sloping floor and / or one or more other flat floor areas may be included to create additional wave areas and / or separate wave zones. Other elements, such as floor configurations, walls, partitions, elevations, land features, etc., may also be included to further enhance the surfing experience or provide additional benefits to the pool wave generator described here. These may include features for splitting, redirecting, reforming, or otherwise manipulating the generated wave.

[0043] Fig. Figure 6 illustrates an exemplary wave generation chamber according to embodiments of the invention.

[0044] Conventional chamber configurations, in which the chamber and pool share a common wall or are in close proximity, generate eddy currents through the area between the chamber and the pool. These eddy currents can disrupt the shape and stability of the generated wave. USPN 10,526,806 discloses a blade positioned between or near the chamber-pool interface to control and direct water movement and reduce eddy current formation. Such systems incur design and maintenance costs because the blades must be internally supported and maintained. Exemplary embodiments described herein enable the formation of a wave pool that can manage or reduce eddy current formation without the use of a blade or internal structure within or adjacent to the water flow path between the chamber and the pool.

[0045] Chamber 62 and its configuration relative to pool 64 can be used to generate waves with desired characteristics. Exemplary embodiments utilize the chamber width CW and the width between the pool and the chamber (wall width) WW to control or influence the currents and waves generated by the chambers. In one exemplary embodiment, the width between the pool and the chamber, WW, is greater than 2 meters. However, the greater distance in this transition area between the chamber and the pool can affect and reduce the height of a generated wave. Therefore, it has traditionally been desirable to keep this area as short as possible. This distance, however, can be used to reduce turbulence and generate a better wave profile. In one exemplary embodiment, the distance between an edge of the pool and an edge of the chamber is between 2 and 7 meters (6 and 21 feet).The chamber width, CW, can influence the resulting height of the generated wave. Similar to the wall width, WW, this dimension has traditionally been reduced because the additional width required additional power to control and release the wave. For example, additional gas would be needed to generate the same pressure on the water surface. The chamber width, CW, is preferably 1.3 to 5 meters (approximately 4 to 15 feet).

[0046] In an exemplary embodiment, the chamber 62 can be coupled to the pool 64 by a passage 66.
