Abstract
In order to improve the accuracy of flood forecasting in basins with dramatic changes in the base course,this paper proposes a coupled hydrological-hydrodynamic flood forecasting model which couples the traditional hydrological model with the one-dimensional hydrodynamic model.First,the flow process of a section was obtained by the hydrological model and was used as the boundary condition of the one-dimensional hydrodynamic model.Then the one-dimensional hydrodynamic model was applied to simulate the flood routing in the river channel.The proposed method was tested on the Waijia River basin in Yantai City,China.The results indicate that the coupled model can simulate runoff yield with a high qualification rate,and generate flow processes that tally with the measured values.It can be concluded that this coupled hydrological-hydrodynamic model may make a significant contribution to flood forecasting in basins with complex hydrologic and hydraulic conditions thanks to its ability to model water movement in the basin.关键词
