摘要
三峡库尾重庆河段位于嘉陵江与长江交汇的河道区域,两江洪水相互顶托,水沙变化十分复杂。三峡工程建成后,重庆主城区河段处于三峡库尾变动回水区,水流条件和泥沙运动规律将发生变化。因此,主要根据2008年度及蓄水前的河道观测资料,对重庆主城区河段的泥沙冲淤变化规律进行初步分析。
Chongqing city is in the interchange of Jialing jiang and Yangtze river.The water and sediment change is very complex.After the three gorges project was built,Chongqing city reached the end of the changes in the three gorges reservoir,the water conditions and sediment movement law will change.Therefore,based on the 2008 data and before data,this article preliminary analysised the sediment bruised and changes regular.
