中文摘要：
随着工程要求的不断提高，感潮河段三维水动力的正确模拟有着十分重要的意义。同时，美国普林斯顿大学开发的海洋模型POM已经逐渐应用于我国海湾潮汐流的数值模拟中，并得到了进一步的修正和完善。本文基于POM模式，利用明渠垂向流速分布的经验公式分析了三种紊动黏性系数计算方法对流速的影响；结合前人对POM模式的修正工作，建立了感潮河段的三维水动力模型；将该模型应用到长江下游太仓段的计算中，结果表明，基于POM模式建立的感潮河段三维水动力模型的计算值与实测值拟合较好，能够充分反映感潮河段水位以及水流流速随时间的变化情况。
英文摘要：
With the new requirements of modeling techniques, 3-D numerical simulation of tidal flow is significant. Princeton Ocean Model （POM） has been widely applied to ocean tides modeling in China with continuous improvements. In this paper, the effects on velocity modeling with different eddy viscosity coefficients are discussed, the 3-D tidal flow model is developed based on POM. The simulation of flow field in Taicang reach of Yangzi river is performed with the model and the calculated values are found to be in good agreement with the observed data. The model has showed the good performances in modeling of water level and 3-D flow field in tidal river.
