Urban inundation problem in the coastal city adjacent to rivers or the sea causes more damage than the problem on inland city. Because the sea level is applied to the external water level conditions, the precipitation of the prevention capacity target against disasters below the average rainfall increases possibility of the inundation. Study area was constructed by the Storm Water Management Model(SWMM). Construction Model was to create a graph of sea level rise and probable precipitation estimated for various return period. As a result, there are differences of probable precipitation by each duration. For example, if overflow rate is decrease by 30 percent, the precipitation of the prevention capacity target against disasters has to be reduced between 9.0 percent and 16.4 percent. In addition, if overflow rate is decrease by 50 percent, the precipitation has to be reduced between 15.7 percent and 26.9 percent. The results of this study can be utilized to determined sea level rise is taken into account prevention Capacity target against disasters estimate data due to climate change.
