Abstract
Recent urbanization and abnormal weather have induced enormous changes in the characteristics of both runoff and pollutant occurrence. Thus, sophisticated watershed modeling of water quality is required. In order to manage non point sources in a watershed, quantitative analysis should be preliminarily performed. However, it is difficult to conduct quantitative analysis since complex natural phenomenon need to be reflected in the modeling. Also, travel time analysis for pollutants and separation of point and non point sources are not easy to carry out. The objective of this study is to quantify non point sources in watershed using soil and land use map and to make the full use of the results in managing non point sources. To do this, non point sources are quantified using a watershed model, SWAT (Soil and Water Assessment Tools). The result of study conform with result of National Institute of Environmental Research.
