| 摘 要： | 基于有限元方法，采用三角形网格，建立了一个高分辨率的潮汐风暴潮数学模型，该模型对复杂岸线和建筑物布置有较好的描述．通过实测资料对该模型进行了验证，验证结果表明该模型能很好地应用于潮汐风暴潮数值模拟．利用该模型对渤海湾西南海域几次潮汐风暴潮过程进行了研究，研究结果表明，持久的偏东大风是该海域风暴潮发展、演变的重要因素，大风引起的增水和风吹流是该海域泥沙输运的主要动力因素．

| Abstract: | In order to fit the boundary and structures better,based on the FEM method and unstructured triangular mesh,a high resolution numerical model is established to study the tide and storm surge. The model is verified by measured data from the southwest coast of the Bohai Bay. The model is used to simulate several storm surge processes in the southwest coast of the Bohai Bay. It is shown that the strong easterly wind is the main cause of the storm surge of Bohai Bay. The sediment transport and siltation is influenced by storm surge. |
