How to solve the problems of sediment deposition and river bed elevation in Wuhai Yellow River water conservancy drifting?

The Yellow River water rafting in Wuhai can solve the problems of sediment deposition and river bed elevation by the following methods: 1. Movable raft: set up movable raft in the area prone to siltation, dredge regularly, and transport sediment from downstream to upstream to reduce coastal siltation. 2. Water and sediment regulation: A diversion dike is set in the river channel, and water and sediment are separated by controlling the flow, so as to reduce river bed siltation and river erosion and make the water and sediment reach a dynamic balance. 3. Economic incentives: Through economic incentives, farmers are encouraged to reduce topdressing and pesticide application, do a good job in shelterbelts, reduce source pollution and protect the Yellow River. 4. River ecological restoration: introduce river ecological restoration technology, moderately carry out pollution interception and vegetation restoration, improve river ecological environment and reduce sediment deposition. 5. Scientific and technological means: modern scientific and technological means such as underwater sediment positioning and underwater topography laser scanning are adopted to realize real-time monitoring and fine management of sediment deposition and riverbed change. Comprehensive application of these methods can effectively solve the problems of sediment deposition and river bed elevation in Wuhai Yellow River Water Control Project.
