원단위법과 SWAT모형을 이용한 농업유역의 영양물질 부하량 추정

Nutrient Loads from Agricultural Watersheds using Unit Loading Factor and SWAT Model

To estimate the nutrient loads from an agricultural watershed, SWAT model and Unit Loading Factor method which was proposed by Ministry of Environment were applied for study watershed. The observed hydrologic and water quality data were compared with estimated methods for the Balhan HP#6 study watershed having an area of $3.86km^2$. The estimated nutrient loads were found to be similar values with the observed.
