三峡水库运行后朝天门河段水流特性变化分析

在三峡工程建成蓄水背景下,本文选择长江变动回水区中段朝天门河段作为代表,根据所搜集的实测水文、泥沙资料,详细研究分析了三峡蓄水后研究河段的水流条件及泥沙输移的变化规律,旨在为该河段河势演变规律研究提供理论支持,同时也为同类河流的研究提供参考。

Analysis on change of flow characteristics of Chaotianmen Reach of Yangtze River after operation of Three Gorges Reservoir

Under the background of the complete and impoundment of the Three Gorges Project， Chaotianmen Reach of the mid-section of the fluctuating backwater region of the Yangtze River is selected as a representative herein， and then both the flow condition and the changing law of sediment transport of the studying rive reach are studied and analyzed in detail in accordance with the collected and measured hydrological and sediment data therein， so as to provide a theoretical support for the study made on the river regime evolution law of the river reach， meanwhile， give a reference for those researches on the similar rivers as well.
