摘　　要：本文建立了海河口一、二维连接水沙数学模型 ,一、二维模型离散格式分别采用Preissmann四点隐式格式和控制体积法。二维模型计算网格采用正交曲线网格 ,具有网格布置灵活和贴合边界等优点。利用海河口系统的水文、泥沙及地形资料对模型进行了全面的检验 ,并进行了河口治理清淤方案优化研究。该模型可推广到其它河口进行挖槽、建闸。A numerical model of sand transport in water flow combined in one and two dimesions was established and used to analyze the sediments at the estuary of the Haihe River. The Preissmann implicit four node scheme and control volume method were respectively employed for the one and two dimentional analysis. The body fitted orthogonal curvilinear grid was applied in the 2D model, when has the advantages of flexible location and fitting to the irregular boundaries. Using the measured data of hydrology, sedimentation and topography in the estuary of the Haihe River, the model was extensively validated. And the examination and optimization for the project of dredging, lock and training wall of the Estuary of Haihe River were conducted.
