| Abstract: | Based on the measured data of the north-trough and south-trough in the Yangtze River Estuary, the vertical distribution of the suspended sediment concentration in the Yangtze River Estuary is simulated by using a one dimensional numerical model of the suspended sediment, and the friction velocity and close-to-bed suspended sediment concentration are briefly analyzed. Comparison results show that the calculated data have a pretty good coherence to the measured data. |
