摘要：Accurately simulate rainfall-runoff process of the lower plain areas is highly complex because of the multi-level drainage system, which is operated by the different authorities in different decision level. The multi-level drainage system is characterized with the high density drainage canals and the large number of sluices and pump stations. A combination of the hydrodynamic model, the hydrologic model, the sluice and pump model was adopted to simulate the rainfall-runoff process in the lower plain area. The outflow of second-level sluice or pump station in sub-district was simulated by the sluice and pump model, and it was coupled to hydrodynamic model in the form of point inflow or distributed inflow. This model combination was verified with the rainfall-runoff process of the Diaocha lake area, which is located in the middle reach of the Yangtze River. Simulation results show that the proposed model combination is effective in modeling historical floods which occurred in the Diaocha lake area.
