WQF 기준 LID 비점오염저감시설의 설계 유량 산정

Estimation of Design Flow Rate for LID Non-Point Pollutants Control Facilities based on Water Quality Flow

본 연구에서는 LID 시설 중 WQF 시설에 대한 다양한 설계기준을 검토하고, 이를 바탕으로 개선된 설계유량이 제안된다. 도시지역을 대상으로 2.5 mm/hr 의 설계유량이 제안되었으며, 이러한 결과는 비점오염저감시설의 합리적인 설계기준을 제공한다는 관점에서 비점오염원 관리에 매우 긍정적인 기여를 할 것으로 기대된다.

In this study several design criteria for LID non-point pollutants control facilities based on water quality flow are investigated. Based on this review, an improved design flow rate is proposed. The desing flow rate of 2.5 mm/hr for LID facilities based on water quality flow is recommended in urban drainage catchment, and this result is expected to be able to make a very positive contribution to non-point pollutant sources management in the sense of providing reasonable design criteria of non-point pollutant control facilities.
