ABSTRACT

The primary cause of 2012 floods is the torrential rains fell in a short period of time, but urban development which did not take into account the risk of disaster damage weighted the flood damage. Especially, in the small and medium-sized cities which are in the status of the lack of disaster prevention budget and infrastructure, the damage was relatively bigger. Therefore, in this study, we examine the developmental and spatial characteristics of Korean small and medium-sized cities, conduct the spatial analysis and on-site investigations for Kunsan, Mokpo, Yeosu City which are damaged by flood in 2012, and analyze the flood damage charateristics. Based on flooded area spatial analysis, two types of flooded area characteristics are derived. One type is the funnel-shaped type which has the steep catchment area in a small area. And, the other type is the bowl-shaped type which has the gentle slope catchment area in a large area. For derived two types, urban planning adaptation methods which are the way for delaying and dispersion of runoff(funnel-shaped type) and the way for reducing runoff(bowl-shaped type) are proposed.
