Impacts of landuse changes on runoff generation in Simly watershed. The spatial and temporal distribution of land use controls the water balance and sediment production in the MRB.Ībbas, T. Changes have led to increased processes such as surface runoff and sediment yield and in the decrease of evapotranspiration. Changes in land use, over the years, resulted in an increase of about 37% in the water yield of MRB. The grazing land increased in 2017 at a few more than double the area that existed in 1987. Overall, during the last three decades, 76.4% of forest was lost in the MRB. Land use maps for 19 were acquired from satellite images. Two scenarios of land use were analyzed over 30 years, which were: a regeneration scenario (referring to use in the year 1987) and another scene of degradation (relating to use in the year 2017). Input data like land use, topography, weather, and soil data features are required to undertake watershed simulation. The study aims to assess the issue of land-use change and its effect on evapotranspiration, surface runoff, and sediment yield. The study was conducted for Mundaú River Basin (MRB) using the Soil and Water Assessment Tool (SWAT) model. Land-use change has a significant influence on runoff process of any watershed, and the deepening of this theme is essential to assist decision making, within the scope of water resources management.
