摘　　要：A coupled 2-D numerical model for hydrody-namic-sediment transport wasestablished and applied to simulate the tides, tidal currents and sediment movement in the submarineRadial Sandbank area of the southern Yellow Sea. With a high-resolution topography dataset used inthe model, the simulation reproduced a fine-structured current field and e-rosion-siltationdistribution. The modeled results show that, in the area of Radial Sandbanks, reversing tidalcurrent and seabed erosion occurs within troughs while tidal current with more rotary feature anddeposition occurs above sandbanks, which indicates the tidal-induced formation of the RadialSandbanks. During a tidal period, associating with the variation of current speed, erosionalternates with siltation. The seabed deformation depends on the relative strength of erosion andsiltation in a tidal period.A coupled 2-D numerical model for hydrody-namic-sediment transport wasestablished and applied to simulate the tides, tidal currents and sediment movement in the submarineRadial Sandbank area of the southern Yellow Sea.
