Research on main indexes for water and sediment regulation based on sediment - carrying capacity of flow and evolution law of river channel 以水流挾沙力和河床演變規(guī)律研究調(diào)水調(diào)沙的主要水沙指標
The problems from sediment discharge for de - siltation and the relative stability of fiver 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 在分析水流挾沙力和河槽水力形態(tài)規(guī)律的基礎(chǔ)上,研究調(diào)水調(diào)沙的流量、含沙量等主要水沙指標,可以解決河道輸沙減淤和河槽相對穩(wěn)定問題。
So far as the alluvial fiver is concerned , the sediment - carrying 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 摘要沖積性河流的河床在輸水輸沙過程中,調(diào)節(jié)流量及含沙量和泥沙組成(調(diào)水調(diào)沙)可以調(diào)節(jié)河床水力幾何形態(tài)和水流挾沙力,追求水沙輸運和河床演變的相對平衡。
