Abstract
In worldwide, soil erosion effect on the water storage structures is significant for proper management of water resource and its use. The effect of soil erosion, improper management system and lack of suitable soil conservation measures have played important role for food production, and global warming problem. For modeling of soil erosion in Nashe watershed a geographical information system (GIS) version-based SWAT has been used to evaluate sensitivities and prone soil erosion area. To predict spatial & temporal soil erosion distribution stream flow calibration and validation of the soil and water assessment tool were applied using the compatible version of SWATCUP against stream flow for Nashe watershed were taken to estimate model performance on monthly basis. Soil erosion involves all parameters are important for feasible conservation of natural, agricultural and built-up environments. To model the soil erosion the analysis was done on over land runoff, soil loss and sediment yield. The model performance(SWAT) has been evaluated by using statistical parameters of (R2) and (ENS) 0.79&0.75 respectively for calibration and validation results 0.71 and 0.65 for R2 and ENS respectively, the results indicate that the best model to forecast hydrological process of the basin or catchment.
