摘　　要：根据分步杂交方法，构造出一个关于河口及浅海环境的三维分步杂交模型。在垂直结构上，本文引入了σ坐标，并在垂直方向上利用交错网格，在水平方向上利用三角形网格离散。本模型在时间上采用分步方法，在不同分步里。A numerical estuarine and coastal seas circulation model is developed with a hybrid method. The governing equations consist of the equation of continuity, the three components of momentum and conservation equations for thermal energy and salt. This model uses the triangle mass concentration finite element grids in the horizontal direction and the σ coordinate in the vertical direction. The circulation model employs the split operators and finite element method. This newly developed three dimensional model follows the method developed by Professor Wu Jianghang and it has the advantages of the original method.
