黄河小浪底水库拦沙后期运用方式探讨

Discussion on the operation mode of Xiaolangdi Reservoir in the late sediment-trapping phase

简要分析了小浪底水库拦沙后期"多年调节泥沙,相机排沙出库"运用的必要性,初步拟定了水库调节指令,结合水库及下游河道淤积发展过程预测,探讨了拟定运用方式的合理性。

In the late sediment-trapping phase, the operation mode of Xiaolangdi Reservoir is supposed to be such way that the sediment process should be regulated on multi-year basis and the sediment should be flushed to the downstream as much as possible on some favorable occasions In the paper, the necessity of such operation mode is firstly analyzed. Based on simulated reservoir sedimentation and downstream erosion/deposition processes, the rationality of the operation mode is then investigated.
