Abstract

This study redefines the concept of socio-ecological resilience within the context of post-flood urban conditions, explores its implications, and proposes a method for assessing it that defines and quantitatively measures urban flood resilience. Drawing on previous research, we identify the key elements used in the socio-ecological resilience framework and establish their conceptual connections. Building on this foundation, we define urban flood resilience and introduce a corresponding quantitative approach. Applying a scenario-based method shows that areas with strong social foundations and preparedness maintain high resilience even as post-flood conditions worsen. Conversely, regions with weak hydraulic capacity and limited social response capabilities experience continuous declines in resilience as flooding increases. These findings suggest that the resulting index can improve disaster-response investment efficiency by aiding in prioritizing investments and maintenance, identifying threshold-risk zones, and developing policy alternatives.

본 연구는 도시 침수 발생 이후 사회생태학적 회복탄력성의 개념을 새로이 제시하여 그 영향을 분석하고 이를 기반으로 최종적으로 도시 침수 회복력을 정의·정량화하는 평가방법을 제안한다. 따라서 본 제안 방법은 선행연구를 통해 사회생태학적 회복탄력성 개념 내에서 활용되는 요소를 분석하고 개념적 관계를 성립하였다. 이를 통해 도시침수 회복탄력성을 정의하고, 그 기반으로 정량화 방법을 제시하였다. 본 연구에서 시나리오에 기반한 도시침수 회복력 정량화 방법을 적용한 결과, 사회적 기반과 대비 역량이 높은 지역은 도시 침수 발생으로 인해 악화되는 조건에서도 높은 회복탄력성을 유지한 반면, 물리적 치수 성능과 사회적 대응역량이 취약한 지역은 침수 심화에 따라 회복력이 지속적으로 저하되었다. 이러한 결과는 도출된 지수가 투자·관리의 우선순위 설정, 임계 위험구간 식별, 정책 대안 설계 등 재난 대응 투자 효율성을 증대 시킬 수 있을 것으로 기대된다.
