Abstract

Land use land cover change have an impact on hydrology of the watershedon theDedissa sun basin. The study mainly focused on estimating land use change and stream flow under different land use land cover changes of the sub basin. Land use land cove maps of 1986and 2010were developed using satellite image throughmaximum likelihood algorithm of supervised classification using ERDAS Imagine 2014. Aphysical-based, semi-distributed hydrological model, SWAT was used to simulate LULCeffects on the hydrological response of Didessa sub-basin.During the studyperiodthe land use land cover has changed due to population growth. The cultivatedland increasedby 12% andwhileforestlanddecreased by 3.61%. The simulatedStream flow results were utilized to analyze seasonal variability stream flow due to land use and land cover changes
