Abstract

The flooding and deterioration of water quality caused by urbanization and climate change are becoming more serious. In order to respond to this, studies on low impact development (LID) technology, which is designed to restore the hydrological system of the urban basin to its natural state, have been actively pursued all over the world, The announcement of the low carbon green growth law, hydrophilic area special law, etc., highlights the importance of technology such as the LID method. However, whereas various developments have been made in relation to the current LID element technology, there has been little research designed to verify its effectiveness. In this study, we analyzed the optimum spatial distribution of pitcher fire pitcher packing in parking lots using the K - LIDM model to verify the effectiveness of the low impact development (LID) method in the early stages. Using the eight package scenario and the three rain intensity scenarios, it was found that the lower 40% pitcher packaging results in an approximately 90% spill reduction effect, as in the case of the whole pitcher's package. The confirmation of these analyses and experimental verification is expected to ensure that the actual pitcher packaging will be used as a basis for arranging LID facilities such as urban planning and housing development in the future.

도시화와 기후변화로 인해 홍수피해의 증가, 수질의 악화 등의 피해가 커지고 있다. 이에 대응하기 위해 전세계적으로 도시유역의 수문학적 체계를 가능한 자연 상태로 복원하고자 하는 기술인 저영향개발(Low Impact Development, LID) 기법에 대한 연구가 활발히 진행되고 있다. 최근 정부에서 발표한 저탄소녹색성장기본법, 친수구역 특별법 등에서는 LID 기법과 같은 기술의 중요성을 명시하고 있다. 현재 저영향개발 요소기술은 다양하게 개발되고 있으나 요소기술의 효율성 검증에 대한 연구는 거의 전무한 실정이다. 본 연구에서는 초보 단계에 있는 저영향개발(LID)기법의 효율성 검증을 위해 K-LIDM 모형을 사용하여 주차장의 투수 불투수 포장 최적 공간 분포를 분석하였다. 8가지의 포장 시나리오와 3가지 강우강도 시나리오를 활용하였으며, 하부 40%의 투수포장이 전체 투수포장과 유사한 약 90%의 유출 저감 효과를 나타내는 것으로 나타났다. 이러한 분석과 실제 투수포장에 대한 실험의 연계를 통하여 향후 도시 계획, 단지 조성 등에 LID 시설을 배치하기 위한 근거 자료로 활용 될 것이다.
