嘉陵江合川枢纽调蓄及泥沙淤积计算

Calculation of store floodwater & sediment deposition on the Hechuan Reservoir in the Jiangling River

修建合川枢纽主要是防洪和拦截长江上游泥沙的需要 .笔者计算了不同冲沙流量时坝前各典型年的水位调度方案 ,运用一维水沙数学模型计算了合川枢纽建成后泥沙的淤积过程、淤积部位 。

The construction of the Hechuan reservoir can store floodwater and reduce sediment deposition of the Yangtze river.This paper gives the dispatch plan of the water level in varies flow on draining off sediment.Moreover,based on the 1-D suspend sediment calculation for the sediment deposition course and position of sediment deposition,analysis on the ratio of draining off sediment & sediment deposition had been done.
