嘎海山水库水文泥沙特性分析

Analysis of hydrological and sediment characteristics of GaHaishan reservoir

根据三家子水文站1957年-2007年的资料,采用水文比拟法,通过面积比推算出嘎海山水库坝址处多年平均径流量及洪峰洪量。运用该站1973年-2007年、1973年-1987年共50年泥沙资料,通过面积比法推求出水库坝址处多年平均输沙量。点绘三家子站历年径流量与年输沙量年际变化过程线,发现径流量和沙量的相应关系较好。通过对养畜牧河上嘎海山水库水文泥沙特性分析计算,为确定多泥沙河流水库特征值提供了解决途径。

According to the data of 1957-2007 of Sanjiazi hydrological station,calculated using hydrologic assimilation method,by the area ratio deducing mean annual runoff and the peak flood discharge of the dam site engineering.using sediment data of 50 years in 1973-2007 and 1973-1987 of Sanjiazi hydrological station,by the area ratio deducing mean average sediment discharge of dam site of ga hai shan reservoir.By plotting the interannual change process line of annual runoff and annual sediment discharge of Sanjiazi hydrological station,water and sand of the whole series has a certain corresponding,showing the corresponding relationship between runoff and sediment discharge is better.Through analyzing and calculating hydrological and sediment characteristics of raising livestock river,in order to provide an effective mean to solve the problem of determining reservoir characteristic parameter of sediment-laden river.
