Abstract:
ABSTRACT Land–use modification is one of the key drivers of variation in watershed hydrology. The effect of forestry related land– use variations (e.g. agroforestry, afforestation, deforestation) on water fluctuations depends on weather, watershed characteristics. The Soil and Water Assessment Tool (SWAT) model was calibrated, validated and used to simulate the influence of agroforestry on the runoff from Talikote sub watershed on Doni catchment of Upper Bheema water basin. Model performance was assessed by Nash-Sutcliffe Efficiency (NSE) and R2 Efficiency. The NSE and R2 values for calibration and validation were R2 =0.74 and NSE =0.6 and R2 =0.82 and NSE =0.65 respectively. Using the land-use refinement tab from HRU in SWAT (ArcGIS interface), various land use scenarios were generated to investigate the change in runoff due to increase in the extent of agroforestry. In the present study an attempt is made to increase the agroforestry area by converting the certain of percentage of cultivable land. Here the percentage increase in agroforestry is done in step of 20 percent i.e. each time an increase of 20 percent is done and a change in runoff from the catchment is evaluated. It has been found that the increase in agroforest results in decrease of runoff. Therefore, this aspect of reducing the magnitude of flood can be implemented to reduce the impact of flood on the region and it can also improve ground water recharge due to percolation at the same time it decreases sediment erosion from the land surface.
