Abstract

This study analyzed the construction and maintenance cost efficiency of Runoff reduction at LID element techniques to analyze the applicability of LID. Using the improved SWMM 5.1 ver analyzed the runoff reduction efficiency of LID element technology. Construction and maintenance costs, the analysis was carried out using the values presented in Washington State University. Permeable pavement is analyzed the highest total runoff reduction efficiency and vegetation swale is analyzed the cheapest construction and maintenance costs. Bio-retention cell is analyzed the highest construction and maintenance cost efficiency of runoff reduction. As a result, Bio-retention cell to be applied in target area can be most effectively reduced runoff.

본 연구에서는 도시유역에서의 LID의 적용성을 분석하기 위하여 LID 요소기술의 시공 및 유지관리 비용 대비 유출저감 효율을 분석하였다. LID 요소기술의 유출저감 효율분석은 새롭게 개선된 SWMM 5.1 ver.을 이용하여 분석을 수행하였으며, 시공 및 유지관리 비용은 Washington State Univ.에서 제시한 값을 이용하여 분석을 수행하였다. 분석결과 총 유출량 저감효율은 투수성포장이 가장 높았으며, 시공 및 유지관리 비용은 식생수로가 가장 저렴한 것으로 분석되었다. 시공 및 유지관리 비용대비 총유출량 저감효율이 가장 높은 LID 요소기술은 생태저류장치로 분석되었다. 결과적으로 대상유역은 생태저류장치를 시공하는 것이 가장 효과적으로 우수유출수를 저감할 수 있다.
