The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.

本文介绍了ELCIRC的理论及使用；基于其在Linux平台下的软件XMGREDIT5生成全三角形网格并评价其特性，认为XMGREDIT5较适合大范围海域而不适用于河道；应用ELCIRC模型计算了长江口的潮流场并进行验证，结果与实测资料吻合良好，且能较好地模拟出地形变化对水流结构的影响；文中对于风场的影响作了定性分析，同时根据实际需要对模型作了改进，如将仅支持长期资料调和常数的开边界条件改为可选择的短期调和常数边界和潮位边界，使二进制格式结果文件数据输出可以处理多点数据及流场等等。
