[0002] Sedimentation is a common problem in water conservancy facilities. Due to sedimentation, the effective storage capacity of the reservoir decreases year by year, the regulation performance of the power station is reduced, and the use and safety of the upstream projects of the dam are affected. At the same time, it poses a great hidden danger to industrial and agricultural production on both sides of the river. There are a large number of power stations in China that have not solved the problem of sediment flushing and discharge.
