사회경제적 환경을 고려한 한국형 도시 풍해 위험지표 모형

In 2012, more than 90% of the damages caused by natural disasters in Korea came from wind disasters such as typhoon and strong wind. Continuously changed climate and expanded urban area increase damages from the wind disasters. To cope with the wind disasters, we need to assess the wind disasters exactly and plan and perform the mitigation projects to the wind disasters using the assessment results. To satisfy these political requirements, in this paper, we proposed a Wind Disaster Risk Index (WDRI) by considering the Korean urban environments through meticulous case studies for the natural disaster risk indexes of Korea and other countries. The proposed index consists of 15 quantitative sub-indexes; 3 sub-indexes in the area of structural vulnerability, 5 sub-indexes in the area of social vulnerability, 7 sub-indexes in the area of response and recovery capability. These sub-indexes can be calculated rapidly and easily by using the data to be managed by the national statistical portal and regional governments and can be integrated to the overall assessment value, i.e. WDRI, by using the nondimensionalization procedure based on the maximum and minimum values of the sub-indexes. Using the proposed WDRI, we can expect that the policy decision makers can define the high risk cities previously and can minimize the damages from the wind disasters by performing the mitigation projects through the efficient and effective resource allocation.
