초록

본 연구에서는 위험도를 나타내는 침수예상도와 취약도를 나타내는 재해취약지수를 동시에 고려한 통합 리스크 지도 작성 방법을 제안하였다. 이 방법은 한 장의 지도에 다양하고 구체적인 정보를 제공함으로서, 대피계획을 동반한 실제 상황에서 활용 가능한 새로운 재해지도를 작성하였다. 재해지도에 인문·사회·경제적인 요소를 고려하기 위해, 연구유역을 노출성, 취약성, 대응성, 복구성 인자로 구분하였다. 그리고 각각의 인자들에 대한 7가지 지표를 GIS 도구를 이용하여 추출하였다. 각 지표별로 추출된 자료를 1~5등급으로 등급화 하였으며, 각 등급화된 자료를 재해취약지수로 선정하여 통합 리스크 분석 및 인자별 리스크 지도 작성에 활용하였다. 침수예상도와 재해취약지수 인자를 중첩한 인자별 리스크 지도는 인구, 자산, 건물 등을 포함한 지역별 상황을 반영하여 대피계획 수립에 활용하였다. 또한, 서로 다른 단위와 성질을 가진 재해취약지수 인자들의 표준화를 통해 하나의 취약도로 환산하고, 위험도를 동시에 고려한 통합 리스크 분석 방안도 제안하였다. 이는 재해지도 작성시 침수 위험도와 사회·인문·경제적인 요인을 동시에 고려한 구체적이고 다양한 정보를 제공할 수 있어 재해에 대한 대비·대응·복구 계획 수립에 기여할 수 있을 것으로 기대된다.

In this study, a method for an integrated flood risk mapping was proposed that simultaneously considers the flood inundation map indicating the degree of risk and the disaster vulnerability index. This method creates a new disaster map that can be used in actual situations by providing various and specific information on a single map. In order to consider the human, social and economic factors in the disaster map, the study area was divided into exposure, vulnerability, responsiveness, and recovery factors. Then, 7 indicators for each factor were extracted using the GIS tool. The data extracted by each indicator was classified into grades 1 to 5, and the data was selected as a disaster vulnerability index and used for integrated risk mapping by factor. The risk map for each factor, which overlaps the flood inundatoin map and the disaster vulnerability index factor, was used to establish an evacuation plan by considering regional conditions including population, assets, and buildings. In addition, an integrated risk analysis method that considers risks while converting to a single vulnerability through standardization of the disaster vulnerability index was proposed. This is expected to contribute to the establishment of preparedness, response and recovery plans for providing detailed and diverse information that simultaneously considers the flood risk including social, humanistic, and economic factors.
