[0002] When designing a water supply project, on the premise of considering that the reservoir water quality meets the requirements, more attention is paid to the requirements of the user's water supply guarantee rate. In a water supply project with a reservoir as the water source, especially in the regulating reservoir of a water diversion project, it is required to meet the water supply volume requirements even at a lower water level of the reservoir. According to the regulations and specifications, when designing the water intake, it is necessary to meet the water supply according to the design capacity at the dead water level of the reservoir. Therefore, the lowest water intake level of the reservoir is the dead water level of the reservoir.

Moreover, the content of impurities such as silt and sediment in the bottom water is high. When supplying water, it is preferred to take the surface water with better quality as much as possible. When the water level is different, the existing miter gate and trash rack designs of the reservoir do not have the function of taking water from different depth water layers to provide water that meets specific requirements.
