Assessment of land use impact on hydrological response using Soil and Water Analysis Tool (SWAT) in Babak watershed, Lombok Island, Indonesia

Changes in land utilization may affect the hydrological function of a watershed. The land use impact on the hydrological response was assessed in the Babak watershed, one of the strategic watersheds on Lombok Island, West Nusa Tenggara, Indonesia. The hydrological response obtained from the analysis using the Soil and Water Analysis Tool considered discharge, runoff, water yield, erosion and sediment transported. Land use change impact was estimated in 2010 and 2013. The results showed that the hydrological response in the Babak watershed was not only influenced by land use change but also by other factors such as climate, soil, geology and topography.
