As a relatively static water body, reservoir water is stratified vertically due to sunshine and climate. The water quality of each stratum varies with temperature. The superficial water is beneficial to crops, while the sub-superficial water is suitable for urban water supply. Accurate intake of water required has always been a challenging for water conservancy projects, especially for large-scale projects requiring huge quantities of water. In the past, the plane steel stoplogs and multi-sided towers were usually used for large-flow water intake. However, there are many problems in these two schemes, including cumbersome operation, too large volume of water intake building, poor effect of water intake and unsatisfactory economy,We need a better water intake system to solve the above problems.
