摘要：The flood of the urban in a basin might be more serious than the urban district in the plain. In this paper, we take the south urban district in the Taiyuan Basin as a case, and set up a 1D-2D model to analyse the runoff and drainage during different designed storm scenarios. The hydrological model calibrated by the designed storm and flood is taken as an inflow boundary of the plain, instead of observed data series. The 1D-2D model is used to model the drainage, surface flow, and flooding. The model shows that the flooding might occur in the urban district during the three designed 24-hour rainfalls, 20 years, 50 years and 100 years, and the roads between building blocks and the low-lying farmland might experience heavy flooding.
