The SWAT model can simulate daily surface runoff, evapotranspiration, soil storage and recharge within the basin. The model was applied to the Gaeun basin. Hydrological components were determined during the period from 2006 to 2007, and the validity of the results was tested by comparing the estimated runoff with the observed runoff on the outlet of the catchment. In most cases, the SWAT model is first calibrated with adjustments in model parameters, and then the validation is performed. And, runoff, T-P and T-N estimation of subwatershed partition was performed. The SWAT model was applied to Gaeun basin with various threshold values in subwatershed partition in this study to examine the effects of number of subwatershed partition on SWAT estimation. However there were big variations in SWAT estimated T-N, and T-P values with the use of various threshold value in watershed partition. The subwatershed characteristics are assumed to be the same for all Hydrologic Response Unit(HRU) within that subwatershed. Estimation Efficiency Analysis(CDE) values for the daily stream was ranged from 0.86 to 0.88. R2 values for daily stream flow ranged from 0.87 to 0.88.
