Exploration of the Technique Detaining the Coarse and Discharging the Fine for Warping Dam

摘要：

An important approach to Sustaining the Healthy Life of the Yellow River is to reduce sediment, especially reduce coarse sediment. The warping dams built in the middle reaches of the Yellow River have retained a great quantity of sediment over the years. However, they were all designed on the ideology, Intercepting and Retaining All Sediment, without allowance for the size-grade distribution of the sediment retained, so trapping a mass of fine sediment. Therefore, when calculating the sediment- retaining benefit of warping dam, only 1/4 of total sediment retention was taken into account, greatly reducing the sediment retaining effect of warping dam on sediment reduction in Yellow River.
