| 摘 要： | 冲积性河流的河床在输水输沙过程中,调节流量及含沙量和泥沙组成(调水调沙)可以调节河床水力几何形态和水流挟沙力,追求水沙输运和河床演变的相对平衡。在分析水流挟沙力和河槽水力形态规律的基础上,研究调水调沙的流量、含沙量等主要水沙指标,可以解决河道输沙减淤和河槽相对稳定问题。

| Abstract: | So far as the alluvial river is concerned,the sedimentcarrying capacity of flow and hydraulic geometry of river channel can be regulated by regulating the composition of flow rate,silt concentration and sediment(water and sediment regulation)during water and sediment discharge;with which the relative balance for water and sediment discharge and the river channel evolution can be obtained.The problems from sediment discharge for de-siltation and the relative stability of river channel can be solved through the study on the main indexes such as flow rate,silt concentration and etc.based on the analysis of sediment-carrying capacity of flow and the law of river channel evolution. |
