Abstract
진주시는 과거 발생한 태풍 및 집중호우 등으로 피해를 입은 지역을 대상으로 홍수침수위험지구를 8곳 선정하고 이 지역에 대한 대피소를 지정하여 운영하고 있다. 본 연구에서는 침수위험지구 중 시가지에 위치하고 인구밀도가 높은 나불지구와 상평지구를 연구 대상지역으로 선정하였다. 침수재해가 발생할 경우 대피조건을 고려하여 아동, 일반성인, 노약자로 구분하고 이동속도와 도달시간을 계산하여 대피소의 위치에 대한 적합성 평가를 GIS의 네트워크분석을 적용하였다. 그 결과 아동과 노약자의 경우 대피시간이 많이 소요되어 대피소로 대피하는데 적정대피 계획시간을 초과하고 있으며 일부지역은 일반성인도 규정된 대피시간을 초과하는 것으로 나타났다. 따라서 나불, 상평지구에 현재 지정된 대피소의 문제점을 보완할 수 있는 대피소를 1-2개 추가 지정하여 대피시간에 따른 문제점을 개선하였으며, 향후 대피경보발령과 연령별 대피계획을 보다 구체적으로 구축하여 재해발생 시 인적 물적 피해를 줄일 수 있는 대책 마련이 요구된다. Jinju city is operating by selecting 8 places as the flood inundation risk area and by designating shelters on this area targeting districts damaged by typhoon and heavy rain, in the past. This study selected the research area as Nabul district and Sangpyeong district where are located in the town and that has high population density out of districts with inundation risk. The network analysis of GIS was applied to the suitability assessment on location of shelter by calculating the moving speed and the arriving time after dividing it into children, general adults, and aged people in consideration of the evacuation condition in inundation disaster. As a result, it was indicated that optimal evacuation plan time for children and aged people exceeded in getting to the shelter because of evacuation time excess and that even general adults outrun the prescribed evacuation time in some districts. Accordingly, a problem for evacuation time was improved by additionally designating 1-2 shelters to existing shelters in Nabul and Sangpyeong districts. A countermeasure is needed to reduce life and property damage in disaster occurrence by implementing the evacuation warning and the age-based evacuation plan more specifically in the future.
