三门峡水库未建成前黄河下游防洪工作仍须紧张进行,就是三门峡水库建成之后,虽根本上消灭了黄河的特大洪水,但从三门峡放下的流量年平均依然可以达到1,000秒公方以上,加上三门以下支流洪水的汇合,最大流量可能达到6,000秒公方以上,且延续时间长,含沙量小。预计这—情况,下游河道必将引起相应的新变化,亦势必危及堤防
Sanmenxia reservoir before the completion of the flood control work in the lower reaches of the Yellow River still need to be tense, that is, after the completion of the Sanmenxia Reservoir, although the drastic destruction of the Yellow River, but the flow down from Sanmenxia can still be achieved an average of 1,000 seconds above the public square, plus three The convergence of branch tributary flood below the gate, the maximum flow rate may reach 6,000 seconds above the public square, and the long duration, small amount of sediment. It is estimated that this situation will inevitably lead to new changes in the lower reaches of the river and will certainly endanger the embankment
