摘要： 通过历年实测资料结合数学模型，对乌江白涛河段近期河床演变状况进行细致分析，中洪水期，郭母子滩挟 沙能力急剧减弱，泥沙沉积形成江心洲及暗礁; 枯水期，该滩产生自左向右横流及扫弯水等不利流态。狮子口滩群 横向边滩变化，纵向航道变深、变窄、变弯; 洪期流速减小，泥沙落淤; 受扫弯水冲刷，左岸向河心位移，形成弯、窄、 浅滩; 大量的人工掘沙也使该滩逐渐变弯变窄。通过本次研究，为该滩群整治工程的方案确立提供了一定的依据。

Abstract: Based on analysis of the near future fluvial process of the Baitao Section of Wujiang River，measured data and mathematical model，the fluvial process of the Baitao Section of Wujiang River was studied in detail; the sediment transport capacity of Guomuzi Bar declined sharply; sediment deposit formed central bar and submerged reef in high-water period; during low-flow period it generated crossflow from left to right flow pattern and sweeping send water etc． Shizikou transitory bar changed laterally; the channel became deeper，narrower and curved; in flood，current declined and sediment deposited; left bank moved to centre river，forming curved bank and narrow bank and flat by sweeping send water; a lot of artificial sand excavations also made the bank narrower and curved． The study provided certain basis to establish plan of the bank group improvement project．

Key words: Baitao Section of Wujiang River, hydrologic sediment, rapids evolution analysis
