Abstract

In this study, rainfall runoff characteristics according to peak concentration were analyzed using the water quality and flow data in the Geumho river, and the direction of nonpoint source management such as monitoring and management period by pollution source was derived. Peak Water Quality Concentration is the concept that utilizes the extreme value as the concentration of non-point pollution control standard with the highest water quality in the rainwater runoff. Using this method, the evaluation factors such as cumulative precipitation(total precipitation), peak water quality concentration, cumulative precipitation up to peak water quality concentration, time to peak water quality concentration, and EMC to peak water quality concentration were examined and long- Rainfall runoff characteristics of nonpoint sources were analyzed. The results of the analysis suggested proper monitoring and management method to manage nonpoint source.

본 연구에서는 금호강의 수질 및 유량 자료를 이용하여 첨두수질에 따른 강우유출 특성을 분석하고 모니터링 및 오염원별 관리 시기 등의 비점오염 관리 방향을 도출하였다. 첨두수질농도(Peak Water Quality Concentration)는 강우유출수내 수질이 가장 높은 농도로 비점오염 관리 기준농도로 극값(Extremal value)을 활용하는 개념이다. 이 방법을 이용하여 누적강수량(총강수량), 첨두수질농도, 첨두수질농도까지의 누적강수량, 첨두수질농도까지의 시간, 첨두수질농도까지의 EMC 등의 평가인자를 검토하였고 장기간에 걸친 실측자료를 이용하여 비점오염원 강우유출특성을 분석하였다. 분석 결과를 통해 비점오염원을 관리하기 위한 적정 모니터링 및 관리방안을 제시하였다.
