| 摘 要： | 应用“河网正交贴体坐标”技术拟合闽江河口多汊道河网，将网格控制在河道有效区域内，使网格空间步长大大缩小，提高了计算的可信度，应用“矩阵追赶法”和“非线性二维潮流模型”等求解方法，很好地模拟了闽江河口复杂的潮流场，计算时间步长可长达10min。该数学模型已在闽江口等多个工程中得到应用，效果良好。

| Abstract: | The reliability of computation results is greatly raised by using boundary fitted ortho- gonal coordinate system on Minjiang Estuary multi-branch river network to control the computation network space step under a smaller size. Matrix chase after method and nonlinear 2-D tidal current model are applied to determine complex tidal flow patterns of Minjiang Estuary, computation time step can be reached to 10 minutes and the result is coincidental. This method is applied on several projects in Minjiang Estuary and the results show very effective. |
