Abstract

The Area Nonpoint Sources Watershed Environment Response Simulation (ANSWERS) model as the distributed hydrologic model for the simulation of 10 scenarios of land uses is presented. The model is based on the assumption that at any point of watershed spatial, runoff volume is closely related to the hydrologic and physiographic processes such as, rainfall intensity, infiltration rate, soil moisture content, soil behaviour, land slope and vegetative cover. The discharge hydrograph of the model gave a good result and was statistically significant to the observed hydrograph.. Among the ten scenarios of land uses, the lowest peak discharge of 7.7. m3/second was obtained at the simulation of 80% of forest land, meanwhile the highest peak discharge of 33.36 m3/second was obtained when there was no forest land at the study area.

Abstract

The amount of sediment which will leave to or deposit in the elements of watershed was able to be calculated by ANSWERS model at different land uses, soil types and land slopes. The simulation model resulted the soil erosion of 2,228 WOK' or equal to 51,99 ton/ha/year at the existing rainfall (21,95 mm). Considering the tolerable soil erosion of the study area of 30 ton/ha/year, the optimal forest land area needed in this watershed is 70% of the total land area, where the soil erosion is still less than the tolerable soil erosion, that is 21, 98 ton/ha/year. This value is less than 58,77% of the existing soil erosion
