Abstract

LID planning and application has been actively developed to reduce the runoff volume at increased impervious areas due to rapid urbanization. In this study, a performance and applicability evaluation was performed in an infiltration trench using the SWMM model, based on the experimental conditions for infiltration trenches. The infiltration trench application area was applied to 5~15% of the drainage area. The SWMM results of discharge and the BOD reduction efficiency were analyzed at a peak discharge of 45.7~61.9%, total discharge of 47.2~62.3%, and BOD load of 52.3~55.3. The discharge and BOD was estimated to be 12~24% higher and 37~38% smaller than the experimental results. This study can help in the application and performance evaluation of infiltration trenches.

도시화로 인한 도시유역의 불투수면적 증가에 따른 우수유출수 증가를 저감하기 위해 저영향개발의 계획 및 적용이 활발하게 진행되고 있다. 본 연구에서는 LID 요소기술 중 침투트렌치의 국내 적용성 및 성능검증을 위해 침투트렌치 실험조건을 바탕으로 SWMM을 구축하여 유출량 및 비점오염원 저감효과를 분석하였다. SWMM의 침투트렌치 적용면적은 전체 유역면적의 5~15%의 면적에 적용하며 모의를 수행하였다. SWMM 모의결과 첨두유출량은 45.7~61.9%, 총유출량은 47.2~62.3%, BOD 부하량은 52.3~55.3%의 저감효율로 분석되었다. 실험결과와 비교하면 유출량의 경우 12~24% 크며, BOD 부하량의 경우 37~38% 작게 산정되었다. 추후 침투트렌치의 적용성 및 성능검증에 도움을 줄 수 있을 것으로 판단된다.
