摘　　要：长江是城市供水重要水源地,取水口附近水下地形容易发生冲刷和淤积。为了解取水口附近的地形变化情况,采用多波束测深系统和无人机系统对取水口进行监测,对采集的数据进行了处理和分析。结果表明:取水口附近水下地形具有上游冲刷、下游淤积的变化规律。研究成果对取水口冲淤变化预测和水资源管理具有重要意义。The Yangtze River is an important source of urban water supply,and the underwater terrain near the water intake is prone to erosion and siltation.In order to understand the terrain changes near the water intake,a multibeam sounding system and an unmanned aerial vehicle system were used to monitor the water intake,and the collected data were processed and analyzed.The analysis results showed that the underwater terrain near the water intake has change law of upstream erosion and downstream sedimentation,The analysis results are of great significance to the prediction of the erosion and sedimentation changes of the water intake and the management of water resources.
