The Yangtze River estuary is a large heavily sediment-laden estuary where the bar shoal with dozens of kilometers in length is formed due to its unique feature of water-sediment movement.

长江口是巨型多沙河口，其特有的水沙运动特点，形成了长达数十公里的拦门沙区段。

如你所知，沉积物是通过风、水流或冰川运动等自然过程输送的物质，如沙子、砾石、化石碎片等。

Based on measured data of water flow obtained from ADCP and of suspended sediment, suspended sediment movement in the Yangtze River Estuary is studied.

采用ADCP实测水流资料与悬沙含量实测资料相结合的方法，对长江口悬沙运动进行分析。
