Abstract
The flood damage shows different types in natural river watershed and in urban drainage watershed. In recent, increasing of the impervious area gives rise to short concentration time and high peak discharge comparing with natural watershed and it is a cause of urban flood damage. In this paper, we use a XP-SWMM model developed based on EPA-SWMM version for analyzing the inundation area, inundation depth and inundation area considering building effect. The two events(2005.06, 2005.07) has been used for the validation of model. HEC-RAS model has been applied for simulation of changing water level, and the results has been used for calculating area of the inundation. The observed inundation area(21.41 ha) in August, 1998 was in good agreement with the simulated value(23.45 ha) of XPSWMM model. An influence of inundation area considering building effects has been analized by the DTM of XP-SWMM model.
