The invention discloses a riverway flood inundation simulation method based on water level monitoring data. According to the method based on the scattered water level monitoring data collected along a riverway, firstly, piecewise linear interpolation is carried out on a center line of the riverway, and water level values of all places along the center line of the riverway are obtained; secondly, on a riverway DEM, the flood water level of each DEM box is worked out according to the nearest neighbor interpolation; lastly, the actual inundation range and the actual inundation water depth distribution of riverway flood are calculated according to the seed region growing method in the riverway. According to the riverway flood inundation simulation method, the natural form change of riverway winding up and down is fully taken into consideration, interpolation is carried out on the value of the riverway water level between water level monitoring stations according to distance parameters, and the interpolation water level distortion problem can be effectively avoided. Meanwhile, the riverway flood inundation simulation method can effectively solve the problem that due to the fact that the number of the flood water level monitoring stations distributed on the riverway is too small, and water level monitoring data sample points are insufficient, a conventional flood water level space interpolation method based on overall areas is hard to apply.

A levee apparatus and system for impeding and controlling the flow of fluids, primarily the flow of water as experienced in a flood or storm surge consisting of a light weight concrete structure with reinforcing steel rebar depending on the application. It is constructed from prefabricated sections with the tongue and groove ends designed to fit together which, when used in conjunction with a rubber gasket, will produce a water tight seal. The structure would be hollow with an opening along the unprotected face to provide a location for the surge water to enter. The structure would have flap-gates on the protected side and on the unprotected side. This would allow flood waters from the protected side to push open the flap-gate and exit the protected side based on the pressure equalization of the flood waters. Once inside the structure any water would then drain from the structure through the flap-gate on the unprotected side when the surge water diminishes. The structure could be placed simply on top of the existing soils or anchored in place to prevent potential changes in alignment. Two main modifications to this design include utilization of a rubberized base which would allow the top portion of the structure to rise into position, and the adjustment of the flap-gate position to change the use of the structure from solely a flood protection system to a retention control system.

The invention relates to a surrounding rock crack growth dynamic monitoring method and a monitoring apparatus thereof. The monitoring method comprises the following steps: punching the inside of a surrounding rock along a direction vertical to the sidewall of the surrounding rock to form a borehole; fixedly arranging airbags in the borehole at certain intervals, and connecting the airbags to an air inflation tube; sending a tester to the borehole, and fixing the tester to a position to be tested; introducing air to the air inflation tube to make all the airbags connected with the air inflation tube be in full contact with the inner wall of the borehole and a cavity be formed between two adjacent airbags, and connecting cavities to water flooding tubes; and sequentially flooding water into cavities from the deep part to the shallow part of the borehole through the corresponding water flooding tubes, recording to the water flooding amount of every cavity, and determining the surrounding rock crack growth condition according to the size of the water flooding amount. A surrounding rock loose range can be measured multiple times only through once punching, so the operation is simple, and the construction cost is reduced; and tests can be simultaneously carried out in different positions of a same tunnel at different times to obtain the time and space evolution rules of the tunnel surrounding rock loose range, and bases are provided for tunnel support design.

A temporary flood relief system for use in the presence of water and impending flooding includes a first container for a prepolymer, a second container for a catalyst, a third container for mixing the prepolymer and catalyst, and a water source connected to the third container. The water source applies the prepolymer and catalyst of the third container to a wall and slab of a building or similar surface that is porous to flood water in absence of restrictive barrier. The system also includes an applicator connected to the third container, and a pressure source connected to the applicator for dispersing the prepolymer and catalyst, as mixed, together with water, using the applicator. The prepolymer and catalyst, on application to the surface in presence of water, foams, expands, and hardens to a pliable solid polymer impermeable to water. The polymer adheres to the surface of application. The flood relief system is unitized as a consumer useable article, containing the prepolymer and catalyst, and application to the surface is possible without human contact of the prepolymer and catalyst. The polymer is easily removed from adherence to the surface after flooding subsides, such as by pressure wash with water.

A flood modeling system defines virtual cells of a geographic region. Some of the cells, referred to as “channel cells,” represent areas within a channel for a moving body of water, such as a stream or river. Other cells, referred to as “land cells,” represent areas external to the channels within the geographic region. The flow of water through the geographic region is modeled as a virtual flow of water through the channel cells and the land cells. The virtual flow of water through the channel cells is modeled via a channel flow algorithm, and the virtual flow of water through the land cells is modeled via a land flow algorithm. For each time step, the system calculates the amount of water that virtually flows out of one cell into adjacent cells. Thus, for any given time step, each cell has an estimated amount of water virtually contained within the cell. The water estimated to virtually flow above ground represents flood water and can be quantified for each cell. Thus, data indicative of the amount of water estimated to be above ground for the land cells can be used to generate an inundation map or for other purposes, such as initiating flood warnings for areas that are modeled to experience a significant amount of flooding.
