摘要
本文通过原型、模型实测资料分析,论述了黄河下游高含沙洪水河床演变规律及高含沙洪水在窄深河槽形成前后输水输沙特性的变化、现行河床条件下高含沙洪水造成洪水传播特性异常的原因和高含沙洪水对河道的破坏作用,意在指出小浪底水库正常运用期内要尽可能地避免出现高含沙洪水或少出现高含沙洪水。
With the data measured in the field and the movable bed model of byperconcentrated flood, the law governing the fluvial processes of the Lower Yellow River , the variations of transportation characteristics of the floods before and after the formation of the narrow and deep main channel, and the reasons for some abnormal propagation phenomena of the floods through the channel are studied The results indicate that the occurrence of the hyperconcentrated floods should be avoided or be as less as possible in the normal operation period of the Xiaolangdi Reservoir
