长江中游戴家洲河段河床演变分析及趋势预测
Alluvial process analysis and trend prediction of Daijiazhou reach in middle Yangtze River
摘要
Abstract
The characters of runoff and sediment of Daijiazhou reach in middle Yangtze River is analyzed.It shows that the plain river characteristics of Daijiazhou reach is obvious.The runoff and sediment verify greatly for each year.The suspended load plays an important role in alluvial process.The characters of river evolution are as follows:the flood river regime is stable whereas the low-water riverbed is unstable;the Chihugang shoal is basically stable;the deposition and erosion of Bahe point bar is alternating;the head of Daijiazhou sandbar is constantly changing ;Zhigang channel alternate between slightly curved channel characteristics and straight channel characteristics; Bahe point bar and the head of Daijiazhou sandbar are closely related to Zhigang channel condition;the position of Zhigang shoal is frequent changing; Combined with impoundment of the Three Gorges Dam,the fluvial trendency of Daijiazhou reach is predicted.关键词
