Based on multi-station tidal current and multi-day continuous observation data, two-dimensional tidal current mathematical model is used to simulate the long, medium and small tide long-term series of the tidal current movement in the radial sandbar of the southern Huanghai Sea. From the dynamic conditions of tidal current ridge development , The multi-objective analysis and research on tidal wave propagation process, tidal wave energy flow rate distribution, tidal wave plane distribution, multi-day average tidal flow velocity, tidal current ellipse and water quality point trace in radiation sandbar sea area are carried out. Numerical simulation results show that tidal current Is the main driving force for the formation of the radiation sand bank in the southern Yellow Sea. The differences in tidal energy and tidal velocity distribution determine the spatial distribution and morphology of the sand ridges and troughs in the northern and southern radiation fields
