초록

현재 수질오염총량제(이하 총량제)에서는 단위유역 말단의 목표수질만 만족할 수 있는 조건에서의 유역 관리를 진행해 왔으며 이로 인해 우선관리가 필요한 지류에 대한 집중적 관리와 오염원 공간분포 특성을 고려한 삭감대책을 마련하는데 제한점이 있다. 본 연구에서는 이러한 문제를 해결하기 위하여 장기적으로 조사된 유량 및 수질자료를 이용한 오염부하지속곡선 기법과 오염원 및 오염부하량 공간분포 특성 분석 방법을 현행 총량제 이행평가 방법으로 적용하였다. 적용유역은 기존 총량제가 시행되고 있는 진위천 수계를 대상으로 하였다. 본 연구방법 적용 결과, 진위천 수계에서는 황구지천 지류가 집중 관리 되어야 하며 진위천 지류는 우선관리에서 제외되는 것으로 나타났다. 또한 황구지천 중류 구간에서 추가적으로 비점삭감계획이 필요하며, 하류 구간에서는 축산에 대한 저감대책이 필요할 것으로 분석됐다. 본 연구에서 제안한 새로운 방법은 향후 총량제에서 유역 전체의 건강성을 높이는데 매우 효과적으로 사용될 수 있을 것으로 판단된다.

It is difficult to manage hotspot area and to establish the reduction plan considering with spatial-distribution on Korea TMDLs (Total Maximun Daily Loads) system. To solve this problems, methods of Load Duration Curve (LDC) using long-term flow and water quality data, and spatial-analysis were applied on present TMDLs. Jinwi A watershed which is enforced TMDLs plan were selected to study area. Results of application of suggested methods in this study to Jinwi watershed, Hwangguji tributary was selected to hotspot area and Jinwi tributary was exclued. Also, middle area of Hwangguji tributary was needed a reduction plan for the protection of non-point source pollution. In downstream area, livestock manure should be managed additionally. The new methods suggested in this study were useful to increase healthiness for total watershed.
