摘　　要：本文立足于潮流模拟和预测的相关研究,通过推导POM水动力模型的控制方程建立三维模型,利用差分方程和偏微分方程的数理方法对模型进行求解,并选取长江口作为仿真水域,利用POM模型对长江口水域进行潮流数值模拟,设置程序的相关参数,并对水深数据进行网格化,选取对长江口潮流影响最大M2分潮作为边界条件进行调和分析,得到仿真水域的边界条件,计算得到潮流、潮速、潮位以及流场图的数据,并进行可视化处理。Based on the current modeling and prediction research, the establishment of three-dimensional model by deriving equations POM hydrodynamic model, using differential equations of mathematical methods and partial differential equations to solve the model, and select the Yangtze River estuary waters as a simulation, he use of the Yangtze Estuary POM model to simulate the trend, set program parameters, and the depth of the data grid, select the greatest impact on the trend of the Yangtze Estuary tidal boundary conditions as harmonic analysis, simulation the waters of the boundary conditions, the calculated flow, tidal speed, tide and data flow field pattern, and visualization.
