NUMERICAL SIMULATION OF THE TIDAL MOTION AND SUSPENDED SEDIMENT TRANSPORT IN THE RADIAL SANDBANK AREA OF THE SOUTHERN YE
A coupled 2-D numerical model for hydrodynamic-sediment transport was established and applied to simulate the tides,tidal currents and sediment movement in the submarine Radial Sandbank area of the southern Yellow Sea.With a high-resolution topography dataset used in the model,the simulation reproduced a fine-structured current field and erosion-siltation distribution.The modeled results show that,in the area of Radial Sandbanks,reversing tidal current and seabed erosion occurs within troughs while tidal current with more rotary feature and deposition occurs above sandbanks,which indicates the tidal-induced formation of the Radial Sandbanks.During a tidal period,associating with the variation of current speed,erosion alternates with siltation.The seabed deformation depends on the relative strength of erosion and siltation in a tidal period.
