摘要
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。
It analyzes the operation of a regulated discharge regime of the river conducted in 2007.The outcomes show that the regulated discharge regime has achieved good results of the whole lower channel scoured,the minimum bankfull discharge of the main channel increased from 3,500 m3/s before the regulation to 3,630 m3/s and successful artificial density current.The main achievements are a) to further accumulate experience in creating artificial density current;b) deepen the understanding on silt-discharge routing law of the lower channel;c) provide prototype observation data for river training works design and;d) prove again that the regulated discharge regime is one of effective measures for increasing discharge capacity of the lower channel,handling the river sediment and keeping the healthy life of the river.
