초록
The primary objective of this study was to analyze the delivery ratio using Hydrological Simulation Program – Fortran (HSPF) in Okdong-cheonwatershed. Model parameters related to hydrology and water quality were calibrated and validated by comparing model predictions with the 8-dayinterval filed data collected for ten years from the Korea Ministry of Environment. The results indicated that hydrology and water quality parametersappeared to be reasonably comparable to the field data. The pollutant delivery loads of the watershed in 2015 were simulated using the HSPF model. The delivery ratios of each subwatershed were also estimated by the simple ratio calculation of pollutant discharge load and pollutant delivery load. Coefficients of the regression equation between the delivery ratio and specific discharge were also computed using the delivery ratio. Based on theresults, multiple regression analysis was performed using the discharge and the physical characteristics of the subwatershed such as the area. Theequation of delivery ratio derived in this study is only for the Okdong-cheon watershed, so the larger studies are needed to apply the findings to otherwatersheds.

Theequation of delivery ratio derived in this study is only for the Okdong-cheon watershed, so the larger studies are needed to apply the findings to otherwatersheds.
