Abstract

In order to respond to the increase in water disasters due to climate change and urbanization, research on low impact development (LID) techniques and application to cities are expanding. The LID technique is a technology that reduces rainwater runoff in the city, controls various water disasters such as flash floods, etc. in an eco-friendly way, and restores the urban water circulation system to a natural water circulation system. However, quantitative analysis of stormwater runoff reduction through the LID technique is insufficient. Therefore, this study analyzed the ratio of the permeable area required to reduce the surface runoff of rainfall (25 mm/hr, 50 mm/hr, 100 mm/hr) with respect to the impervious watershed area of the old city using the permeable pavement. As a result of the analysis, it was found that a permeable area ratio of 7.14 to 12.63% of the total area was required for 25 mm/hr, 15.79 to 26.97% for 50 mm/hr, and 30 to 55.81% for 100 mm/hr.

기후변화와 도시화로 인한 수재해의 증가에 대응하기 위해 저영향개발(Low Impact Development, LID) 기법에 관한 연구와 도시 적용이 확대되고 있다. LID 기법은 도시 내 우수유출수를 저감시키며 돌발 홍수등 다양한 수재해 문제를 친환경적으로 제어하고, 도시 물순환 체계를 자연 물순환 체계로 회복시키는 기술이다. 하지만 LID 기법을 통한 우수유출수 저감의 정량적 분석이 부족한 실정이다. 따라서 본 연구에서는 투수성 포장을 활용하여 구도심의 불투수 유역면적에 대하여 강우(25 mm/hr, 50 mm/hr, 100 mm/hr)의 지표유출 저감시 필요한 투수면적의 비율을 분석하였다. 분석 결과 25 mm/hr에 대하여 전체면적대비 7.14~12.63%의 투수면적이 필요하며, 50 mm/hr에 대하여 15.79~26.97%, 100 mm/hr에 대해 30~55.81%의 투수면적비가 필요한 것으로 나타났다.
