Abstract: To study the channel conditions and trends in the Yangtze River from Fuling to Changshou since the impoundment of Three Gorges Reservoir,a large of hydrological data of water level along the reservoir area and flow data of representative hydrologic station were collected. One-dimensional flow mathematical model was used to calculate the navigation flow conditions including water depth,flow speed,slope from Fuling to Changshou under third-level characteristic flow at initial period of Three Gorges Reservoir impoundment. Flow condition changes were analyzed comparatively,and channel condition improvement was briefly introduced.

Key words: Three Gorges Reservoir, initial period, one-dimensional flow mathematical model, channel changes

摘要: 为研究三峡蓄水以来涪陵至长寿河段水流条件的变化情况,收集了三峡工程各蓄水期库区沿程各水位站水位 资料,以及库区代表水文站流量资料。利用一维水流数学模型计算了成库初期3 级特征流量下涪陵至长寿河段通 航水流条件( 水深、流速、比降) ,进行了水流条件变化对比分析,简述了航道条件改善情况
