对黄河2007年调水调沙生产运行情况进行了分析,结果表明:本次调水调沙取得了下游河槽全线冲刷、主河槽最小平滩流量由调水调沙前的3 500 m3/s增大到3 630 m3/s和人工塑造异重流成功等良好效果。取得的主要收获有:①进一步积累了人工塑造异重流的经验;②加深了对下游河道水沙演进规律的认识;③为河道整治工程设计提供了原型观测数据;④再次证明调水调沙作为扩大下游河道排洪能力、处理黄河泥沙、维持黄河健康生命的措施之一是行之有效的。
The operation of water and sediment production in Yellow River in 2007 was analyzed. The results showed that: the water and sediment adjustment made the entire downstream river channel erosion, and the minimum flat beach discharge in the main channel increased from 3 500 m3 / s before water and sediment adjustment Large to 3 630 m3 / s and artificially shaped heavy flow success and other good results. The main gains are: ① further accumulated experience of artificially shaping the gravity flow; ② deepened the understanding of the law of water and sediment evolution in the lower reaches of the river; ③ provided prototype observation data for the design of river regulation works; ④ once again proved that water and sediment regulation As one of the measures to expand the discharge capacity of downstream rivers, deal with the Yellow River sediment and maintain the healthy life of the Yellow River, it is effective.
