胶南近岸海域三维潮流数值模拟

Numerical Simulation of 3D Tidal Current in the Offshore Area of Jiaonan

为胶南海域沿岸污水排海选址,海洋环境管理提供动力条件,基于变边界河口、陆架、海洋(ECOM)模式,模拟了胶南近岸海域三维潮流场。研究海域水平最大流速在斋堂岛水道,量值为1.0m/s。垂直流速表现为底层大,表层小的特点,其最大值分别为25.38×10-4m/s和9.9×10-4m/s。计算结果与实测结果符合良好,较好地刻画了胶南近岸海域M2分潮潮流场的时空分布特点。

In order to provide a dynamical condition for the offshore area in the selection of sewage discharged location and environment management. Based on a 3-d estuary coastal and ocean model (ECOM model) with a variable boundary, the 3-D tidal current field in the offshore area of Jiaonam is simulated. The maximal horzontal velocity of current, 1m/s, is located at the Zhaitang island channel. The vertical current velocity in the surface layer is less than that in the bottom layer. The vertical maximal velocity is 25.38×10 -4 m/s and 9.9×10 -4 m/s in the surface layer and bottom layer, respectively. The computed result agress with the observation well. It gives temporal and spatial distributions of M_2 tidal current in the offshore area of Jiaonan.
