什么是调水调沙 所谓调水调沙,就是在充分考虑黄河下游河道输沙能力的前提下,利用水库的调节库容,对水沙进行有效的控制和调节,适时蓄存或泄放,调整天然水沙过程,使不适应的水沙过程尽可能协调,以便于输送泥沙,从而减轻下游河道淤积,甚至达到冲刷或不淤的效果,实现下游河床不抬高的目标。
The so-called water and sediment regulation The so-called water and sediment regulation, that is, taking full account of the Yellow River downstream sediment transport capacity of the premise, the use of reservoir regulation capacity, water and sediment for effective control and regulation, timely storage or discharge, adjust The process of natural water and sediment can make the unaccompanied water and sediment process coordinate as much as possible so as to transport sediment so as to reduce the siltation of the downstream river and even achieve the effect of erosion or non-siltation, so as to achieve the goal of not lowering the downstream river bed.
