Analysis of the Disaster Environmental Change Considering Climate Change : 2. Flood Risk Area Assessment

Abstract The climate change has clearly affected most parts and systems in the globe. Particularly, the recent global warming is pre-sumed as the main reason of the increasing severe flood frequency, resulting a significant damages on the human life and prop-erty. This increasing trend on the occurrence of severe flood is very remarkable in the Korean Peninsula as well. Therefore, theappropriate flood prevention and mitigation methods are required. In this study, to assess the climate change effects on floodingrisk areas in the Nakdong river basin, the flood and river acts from Korea and other countries were investigated and the current sit-uation and problems were analyzed. The flood risk considering climate change were also assessed for the flood risk areas amongthe natural disaster risk areas proposed in 2010 to suggest the future management strategy against the future severe flood damage.The proposed flood risk assessment results for the flood risk areas might be used as a basic information to develop climate changeadaptation strategy.Key words : Climate change, Flood risk assessment, Flood management, Natural disaster risk area
