Three-dimensional numerical simulation of tidal current in offshore area of Haizhou Bay

Based on 3D estuary,coastal and ocean model(ECOM3D),a 3D tidal current model for moving boundaries was established by introduction of dry-wet network method for moving boundary treatment.The application of the model to 3D numerical simulation of tidal field for offshore area of Haizhou Bay shows that the calculated result of the model agrees well with the measured data, and that the model is successful in simulation of the temporal and spatial distribution of tidal field of tidal constituent M2 of this area: the flow velocity in this area is 40-65 cm/s,the velocity in vertical direction is 10-4m/s in the order of magnitude,and the maximum flow velocity in vertical direction is 5.2×10-4m/s.
