海州湾海域三维潮流数值模拟

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

基于三维河口、陆架、海洋模型（ECOM3D），引入干湿网格法变动边界处理技术，建立三维动边界潮流数值模型．将该模型用于海州湾近岸海域三维潮流场模拟，结果表明，模型计算结果与实测值吻合良好，较好地模拟出此海域M2分潮的潮流场时空分布特点：大部分海域流速在40—65cm／s之间。垂直流速量级为10^-4m／s，最大垂直流速为5．2×10^-4m／s．

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.
