ESTIMATION OF FLOOD DAMAGE UNDER CLIMATE CHANGE WITH CONSIDERING DEPOPULATION AND ASSET DISTRIBUTION CHANGE

Abstract

 The change of flood damage due to climate change and depopulation was estimated in this study by combining flood simulation and multiple asset distribution change scenarios. It was found that each effect varies depending on basins and thus flood controls should be determined for each basin. Moreover, it was confirmed that asset concentration in urban areas can increase flood damage and the efficiency of flood measurement can be different according to the planned precipitation. These results indicate that it is necessary to consider flood control on city planning.
