中文摘要：

一个新三维的半含蓄的有限卷的海洋模型为模仿沿海的海洋发行量被开发了，它在垂直方向在水平方向和 z 水平格子基于蹒跚的 C 未组织的非直角的格子。三维的模型是由半含蓄的 finite-volumemethod 的 discretized，因为免费表面并且垂直散开半含蓄的、从而搬迁的稳定性限制与表面严肃波浪和垂直散开条款被联系。在动量方程的留下的条款由一个不可分的方法明确地是 discretized。部分房间方法被用于解决地形学，它使模型能更好代表不规则的地形学。模型为风和潮汐的摆动循环靠着分析盒子被测试了，并且被用于在 Bohai 海模仿潮汐的流动。结果与分析答案 andmeasurement 结果两个都在好同意。

英文摘要：

A new three-dimensional semi-implicit finite-volume ocean model has been developed for simulating the coastal ocean circulation, which is based on the staggered C-unstructured non-orthogonal grid in the hor- izontal direction and z-level grid in the vertical direction. The three-dimensional model is discretized by the semi-implicit finite-volume method, in that the free-surface and the vertical diffusion are semi-implicit, thereby removing stability limitations associated with the surface gravity wave and vertical diffusion terms. The remaining terms in the momentum equations are discretized explicitly by an integral method. The partial cell method is used for resolving topography, which enables the model to better represent irregular topography. The model has been tested against analytical cases for wind and tidal oscillation circulation, and is applied to simulating the tidal flow in the Bohal Sea. The results are in good agreement both with the analytical solutions and measurement results.
