【Abstract】 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.更多还原
