The purpose of study is to investigate the relationship between the surface runoff rate defined as a proportion of annual surface runoff to annual average precipitation and stream water quality. For this, the surface runoff rate was first estimated in the Han River basin located in South Korea using the calibrated and validated HSPF model, and the statistical analysis was then performed to investigate correlation between computed surface runoff rate and observed water quality. In addition, the applicability of surface runoff rate as indicators to measure the impacts of land development on stream water quality was evaluated by using the receiver operating characteristics (ROC) analysis. The results of the statistical analysis and ROC analysis indicated that there were the significant relationships between surface runoff rate and higher proportions of surface runoff could lead to higher concentrations of BOD, COD, and T-P in streams. In addition, the results from this study suggest that it is needed to manage and control the surface runoff rate within about 15% for prevent the degradation of stream water quality.
