摘要
分析了自2002年起小浪底水库每年实施调水调沙在黄河下游河道冲刷中的作用,指出小浪底水库调水调沙有利于下游河道冲刷,但通过资料分析,冲刷的幅度有逐年变小的趋势,为此,恰当地评价当前调水调沙的作用十分必要。
The function of water and sediment transfer of Xiaolangdi Reservoir to the river erosion of the lower reaches of the yellow river has been analysed since 2002 and pointed out that the water and sediment transfer is benefit to the river erosion.However,according to recent data,river erosion amplitude is becoming smaller year after year.Therefore,proper evaluation of the function for current water and sediment transfer is quite necessary.
