Application of SWAT in Non-Point Source Pollution of Upper Xiliaohe Basin, China

Non-point source pollution is one of the major problems caused by agricultural activities especially from planting cultivation. This paper describes the application of the Soil and Water Assessment Tool (SWAT) model in agricultural non-point source pollution of the Laohahe River watershed, located in northeast China. This initial hydrologic modeling analysis will facilitate future applications of SWAT to this area for various watershed analyses, including water quality.
