Rainfall-runoff process in watershed is caused by drainage structures, which are certainly to determine. As rainfall-runoff processes was developing from lumped hydrological models to distributed one in accordance with the development and distribution of on-line digital geographic data, it is surely more important to establish a drainage structure.
In order to simulate the exact rainfall-runoff process, The stream network of area-threshold based on the DEM was configured and analyzed by applying the stream network of slope-area threshold method. Yongdam Dam basin was selected for analysis, which was divided into 31 sub-basins by the SWAT model. SWAT model has created a HRU using soil map and cover degree of divided sub-basins. Input data required for the model (rainfall, maximum and minimum temperature, solar radiation, relative humidity, and wind speed data) are obtained through the WAMIS. SWAT model was set up to analyze the coefficient of roughness and process-specific analytical methods. The results were obtained by the SWAT model in Yongdam dam basin.
From results between area-threshold and slope-area threshold method stream network in Yongdam dam basin, there was no significant differences. To analyze the results of specific period or to expend the water shed networks, it is necessary to conduct analysis of the SWAT model as a stream network of slope-area threshold method.
