Recently, occurrences of localized heavy rainfall and the risk of the urban flooding are increase in urban area. Urban flood is occured rapidly after rainfall occurred. For these reasons, we developed the flow nomograph, which can be used quickly. The flow nomograph based on rainfall information is assembled and comprised by the relationship with flood discharge and level from rainfall scenarios. The application watershed is Cheonggye stream, Korea. As a result of assessment, more than 88% among 10 rainfall events were suitable. Furthermore, we will develop flow nomograph at Toga river and use the MP-X radar for leadtime of rainfall.
