A Study on Runoff Characteristics of Non-Point Source Pollution with Rainfall in Mandae-cheon Watershed
만대천 유역의 강우량에 의한 비점오염물질 유출특성에 관한 연구

Abstract
Non-point source pollution, which is found in soil, urban area, and agricultural area, is difficult to have its amount to be estimated. Moreover, it is hard to come up with a counterplan to cope with this pollutant. Hence, the watershed of Mandae-cheon located at the upstream of Soyang Lake was chosen as our site of study. We analyzed the relationship between precipitation level of each month and pollution load in the watershed by using statistical methods: measuring BOD, T-N and T-P - which are the causes of eutrophication - in the water; and analyzing the changes in water quality caused by precipitation level of nth.
