Abstract

Purpose: This study proposes measures to enhance Korea’s flood protection standards for underground spaces in response to the increasing urban flood risk driven by climate change. Methods: The Natural Disaster Countermeasures Act and related ministerial notices were reviewed to assess Korea’s current framework and limitations. These were compared with Japan’s large-scale engineering measures and the Netherlands’ risk-based policies, focusing on legal, technical, and operational aspects. Results: Korea’s approach remains reactive and compliance-oriented, whereas Japan and the Netherlands adopt proactive, goal-driven strategies. Japan prioritizes large-scale drainage infrastructure, while the Netherlands sets differentiated risk-based targets within an integrated management system. Conclusion: Recommended improvements include (1) adopting risk-based performance targets, (2) shifting to integrated detection–warning–barrier systems, and (3) strengthening enforcement for facility installation and maintenance.

연구목적: 기후변화로 심화되는 도시 홍수 위험에 대응하기 위해, 국내 수방기준을 고도화하는 방안을 제시한다. 연구방법: 자연재해대책법과 관련 고시를 중심으로 국내 제도의 현황과 한계를 분석하고, 일본(대규모 공학적 해결책)과 네덜란드(정교한 위험기반 정책)의 제도·기술·운영 사례를 심층 비교분석하였다. 연구결과: 국내 제도는 재난 발생 후 대응하는 반응적·규격중심적 특성이 강한 반면, 일본과 네덜란드는 각각 선제적·목표지향적 접근을 채택하고 있다. 일본은 대규모 방수 인프라를 통한 물리적 대응에 강점을 가지며, 네덜란드는 위험도를 반영한 차등적 목표 설정과 통합 관리체계를 운영한다. 결론: 국내 수방기준 개선을 위해 (1) 침수 결과의 심각성을 고려한 위험기반 차등 목표기준 도입, (2) 개별 시설물 중심에서 감지-경보-차단이 연계된 통합 시스템으로의 전환, (3) 시설물 설치·유지관리의 실효성 확보를 위한 이행력 강화가 필요하다.
