A method and apparatus for generating a wave in a body of water may include altering a flow of water as it is urged through an inlet, contoured passage, and outlet. For example, a primary flow of water may be altered so that one or more secondary flows are created at angles to the direction of primary flow.

A system of solar panels over a water reservoir may include a plurality of piers secured to a floor of the water reservoir and extending from the floor to a fixed elevation above a maximum water elevation of the water reservoir. The system of solar panels may also include at least one support structure on the plurality of piers. The system of solar panels may also include a plurality of solar panels supported by the support structure over at least a portion of the water reservoir. The plurality of solar panels both reduce evaporation from the water reservoir and generate solar electricity.

Disclosed is a composite hydrological monitoring system, in which a counterweight component and a test component are respectively connected to both opposite ends of a strip and a plurality of sensors are disposed at different vertical positions. Accordingly, the scour depth can be measured by sensing the location of the counterweight component, whereas the water level and/or flow velocity can be determined by signals from the sensors. When the counterweight component moves downward with sinking of the riverbed, the strip would be pulled down and thus causes the test component to present a change in mechanical energy. Accordingly, the sinking depth can be measured by sensing the change of the mechanical energy. Additionally, since the water level variation would cause signal changes of the sensors arranged in a row along a vertical direction, the change of water level can be determined accordingly.

The present invention discloses a method for constructing inner dump type strip mine pit bottom reservoirs section by section, specifically including the following steps: S1: processing end slopes: discarding clay at a lowest step of an inner waste dump of a strip mine; S2: discharging concrete to slope faces of lowest steps of the end slopes on two sides of a pit bottom; S3: sealing the bottom; S4: discarding gravel into a pit of the strip mine; S5: laying geotextile; S6: re-adopting clay on the lowest steps of the end slopes of the inner waste dump, so as to form a reservoir sealing isolation layer; S7: constructing a plurality of reservoirs step by step in an advancing direction of the strip mine; S8: storing water resources: completing installation of water storage wells; S9: completing installation of water fetching wells; S10: storing water resources.

Provided is a pier scour protection method by combinating a downward bivariate normal distribution surface and a granular mixture, wherein the method is used for protecting a pier foundation of a sea-crossing or river-crossing bridge from scouring, and when a depth of a local scour hole around the bottom of a pier or a bridge pile reaches a set depth, a downward bivariate normal distribution surface protection structure is laid, and the granular mixture with a specific thickness is laid in the downward bivariate normal distribution surface protection structure. A downward bivariate normal distribution surface structure for defending and a granular mixture layer for weakening horseshoe-shaped vortexes in a scour hole are organically combined, the bivariate normal distribution surface structure is mainly used for defending the downflow in front of the pier, and the granular mixture layer can weaken the horseshoe-shaped vortexes around the piers.

A system and method for floodwater redistribution is disclosed. The system being comprised of onshore and offshore pump stations and pipelines deployed along the Gulf Coast to redistribute floodwaters to reservoirs located in the western United States. The pump stations include a network of controllers which monitor input/output head pressures and pump speeds and submit the data to the system server to determine the pump settings needed to optimize water flow along the line.

This invention is a device for creating tidal action in a terminal lake. A first aspect involves staggering of input and output from the terminal lake, such that the level of the lake rises and falls on a daily basis to simulate tidal action. A second aspect involves the creation of a berm and islands, with a system of pumps and drains filling and emptying a series of holding ponds, creating an even greater “reach” of the tidal action. This tidal action allows for the growth of mangrove forests, which prevent land-based predators such as coyotes from accessing bird nests on the islands, as well as keeping the “playa” wet enough so that local wind does not pick up playa sediment and create toxic dust storms. The toxic upper 3″ of the “playa” is bulldozed to create the berm, islands, and access roads which bisect the newly-created intertidal zone.
