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 presumed as the main reason of the increasing severe flood frequency, resulting a significant damages on the human life and property. This increasing trend on the occurrence of severe flood is very remarkable in the Korean Peninsula as well. Therefore, the appropriate flood prevention and mitigation methods are required. In this study, to assess the climate change effects on flooding risk areas in the Nakdong river basin, the flood and river acts from Korea and other countries were investigated and the current situation and problems were analyzed. The flood risk considering climate change were also assessed for the flood risk areas among the 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 change adaptation strategy.
