도암호 유역의 융설에 의한 수질 변화 모니터링

초록

The Doam Lake Watershed is one of Gangwon-do’s non-point source management areas. This area has a lot of snowfall in winter, and it is expectedthat there will be a lot of soil erosion in early spring due to snow melting. In this study, snow melting was monitored in the Doam Lake watershedfrom February to 3, 2020. It was conducted to analyze the water quality changes by calculating the concentration of non-point source pollution causedby snowmelt, and to compare the concentration of water quality during snowmelt event with rainfall and non-rainfall event. As a result of water qualityanalysis, Event Mean Concentration (EMC) at the first monitoring was SS 33.9 mg/L, TP 0.13 mg/L, TN 4.33 mg/L, BOD 1.35 mg/L, TOC 1.84 mg/L. At the second monitoring, EMC were SS 81.3 mg/L, TP 0.15 mg/L, TN 3.12 mg/L, BOD 1.32 mg/L, TOC 3.46 mg/L. In parameter except SS, itshowed good water quality. It is necessary to establish management measures through continuous monitoring.
