In recent, the rainfall is showing different properties in space and time but the ground rain gauge only can observe rainfall
at a point. This means the ground rain gauge has the limitations in spatial and temporal resolutions to measure rainfall and
so there is a need to utilize radar rainfall which can consider spatial distribution of rainfall This study tried to apply radar
rainfall for runoff simulation on an urban drainage system. The study area is Guro-gu, Seoul and we divided study area
into subbasins based on rain gauge network of AWS(Automatic Weather station). Then the radar rainfalls were adjusted
using rainfall data of rain gauge stations the areal rainfalls were obtained. The runoffs were simulated by using XP-SWMM
model in subbasins of an urban drainage system. As the results, the adjusted radar rainfalls were underestimated in the
range of 60 to 95% of rain gauge rainfalls and so the simulated runoffs from the adjusted radar and gauge rainfalls also
showed the differences. The runoff peak time from radar rainfall was occurred more fast than that from gauge rainfall.
