Abstract

The increase in impervious surfaces due to urban development has caused a groundwater drawdown through the reduction of underground infiltration, flood disaster due to increased rainfall runoff and environmental pollution in higher pollutant concentrations of first flush rainwater. As an alternative to these problems, the needs of low impact development (LID) techniques is increasing in urban areas. In this study, the restoration efficiency of water cycle was assessed at a residential site development applied with the LID rainwater management system. The results of monitoring the water cycling showed that the efficiency of water cycle of LID rainwater management system was improved 41% more than that of conventional methods.

도시개발로 인한 불투수면의 증가는 우수의 지중 침투량 감소에 의한 지하수위 하강, 강우 유출량 증가에 의한 침수해, 고농도 초기 우수에 의한 환경오염 등의 문제를 야기시킨다. 따라서 이러한 문제에 대한 대책방안으로서 저영향개발 기법 도입의 필요성이 증가하고 있다. 본 연구에서는 저영향개발 (LID) 기법이 적용된 단지 내 빗물관리시스템 모니터링에 의한 물 순환 복원효율을 분석하였다. 본 연구에서 빗물관리시스템을 적용한 단지 개발에서 기존 방식에 비교하여 물 순환 효율이 41%가 증가하였다.
