Study on the Operation Mechanism and Effect of the Yellow River Water and Sediment Regulation System

In order to scientifically deal with the problems of less water and more sediment in the Yellow River and the uncoordinated relationship between water and sediment, it is necessary to establish a perfect water and sediment regulation system. Through the calculation of the sediment transport capacity of the Yellow River and the application of the water and sediment regulation system, it is found that the sediment transport efficiency of the Yellow River will increase with the increase of water flow, and there will be an obvious inflection point near the flat discharge. The joint regulation of the backbone reservoir group can discharge the large discharge close to the minimum flat discharge of the downstream river, which improves the sediment transport capacity of the river and alleviates the problem of sediment deposition. In this paper, through the introduction of the Yellow River water and sediment regulation project system, regulation indicators and mechanisms, the author discusses in detail the Yellow River water and sediment regulation scheme and its operation effect, hoping to provide help promote the improvement of the Yellow River governance effect.
