摘　　要：应用圣维南方程组、普赖斯曼隐格式及双扫描解法等提出了感潮河段洪潮遭遇的非恒定流数值计算模型,并对感潮河网中所常见的边界条件进行了分析研究。计算与实测结果比较表明,所采用的方法有效可行。In this paper, the unsteady flow in a tidal waterway is simulated by using Saint-Venant equations and Preissmann implicit scheme method. Various interior boundary conditions which occurred frequently are fully analyzed. The comparison of simulation results of the tidal flow in the Yong River with measurements proves that the method presented is valid.
