Analysis of Sediment Movement in the Yangtze River Estuary

YU Dong-sheng

Abstract

According to ADCP data and suspended sediment concentration,suspended sediment movement in the Yangtze River Estuary is studied.The result shows that sediment re-suspended is arisen by tide,the change of suspended sediment concentration lags the change of flow velocity,and the peak value of suspended sediment concentration lags the peak value of flow velocity.Suspended sediment has three transport modes,and the relationship between tidal discharge and sediment discharge is also studied.
