Sumpur Watershed is ha5,478 hectares in West Sumatra Province which is one of Watershed priority. Located of the slope of Mount. Merapi is a complex area with various type of landuse and flows to Techtronic Lake Singkarak. The purpose of the study are predict of surface runoff and erosion by hydrology model SWAT to find impact of land use change on hydrology response. Land use change in watershed in dominated by decreasing of paddy field area area in 10 years the forest is reduced by about 2672 Ha, while the agricultural field cover for 10 years increased by 2334 Ha. The decreasing of forest area is about 128 hectares. Impact of land use change the impact of this land change increases surface flow by 18.2 mm/year while the base flow becomes reduced by 17.6 mm/year. The land use change also increased loading sediment about 6.2 Ton/ha/years. Whereas the mudflow watershed flows to the lake Singkarak whose water is used for electricity generation
