Recently there has been an increasing occurrence of flooded area in Korea. Most of these flooded area occurred roadside in the city or residential areas. For predictive flooded area susceptibility mapping, this study applied and verified probability model, the frequency ratio at Busan, Korea, using a Geographic Information System (GIS) and Statistical methods. Flooded areas were identified in the study area of field surveys, and maps of the topography, geology, landcover and green infrastructure were constructed to spatial database. Using this analysis results, part of urban planning can find ideal locations for GIS which are needed. This result expects that this planning framework can bring flood mitigation of city.
