AB - The purpose of this study was to simulate the reduction effect of soil loss in the Yongdam
reservoir watershed using SWAT model. To evaluate accuracy for flow and sediment yield of
SWAT model, calibration was performed for the period from Jan. 2002 to Dec. 2003, and the
verification for Jan. 2005 to Dec. 2005. The calibration and the verification were carried out using
data observed at the Cheoncheon gaging station. The R2 and EI values in terms of a flow were
0.8 and 0.78 respectively for calibration, whereas they for verification were 0.88 and 0.86
respectively. In terms of a sediment yield, they were 0.7 and 0.48 respectively for calibration,
whereas for verification were 0.64 and 0.54 respectively. As a results from model simulation,
annual mean soil loss rates in terms of forest, paddy and upland were 0.02 ton/ha/yr, 0.15
ton/ha/yr and 7.58 ton/ha/yr, respectively. The results show that the land use type of a
upland has more significant impact on a total soil loss as well as a sediment yield than other
types of land use. The sediment delivery ratio was determined to be about 0.35. In this study 2
land cover change scenarios for upland area were considered. These scenarios were used an
input to SWAT model in order to evaluate their impact on soil loss and sediment delivery. The
results show that a reduction of the upland area would reduce the soil loss and sediment yield.
