Abstract：Aiming at the new challenges brought by frequent sudden drought-flood transition events to the operation of water conservancy facilities,this paper takes the bidirectional flow channel irrigation and drainage pumping station as the research object,and summarizes its application characteristics and design optimization methods under working conditions such as low head,large flow,and large water level fluctuation.Taking an X-type bidirectional flow channel irrigation and drainage pumping station built in Gaochun District,Nanjing in 2022 as an example,the design and operation scheme of the bidirectional flow channel and CFD simulation optimization results are described.The pumping station achieves irrigation and drainage function switching through double-layer flow channels,and operational practice shows that the design scheme is scientific and reasonable.Meanwhile,the room for improvement in high sediment-laden watershed application,standardization development,and simulation technology is analyzed,and the direction of promotion and application is prospected.
