Abstract

Water issues in Uttar Pradesh are stressed due to rising population and climate change. The studies showed that in future the changing climate and intense human activities would complicate the situation endangering the water and soil resources. To support sustainable uses of these resources an appropriate model is required in this area, and to develop such model runoff, evapotranspiration and soil erosion modeling is essential. In this paper Soil and Water Assessment Tool (SWAT) is used to model hydrological processes of a watershed in ganga basin. Ten years of daily meteorological data, soil data procured from National Bureau of Soil Survey(NBSS), Digital Elevation Model of ninety-meter resolution and Landsat 8 satellite imagery are used as inputs. The watershed was divided into 39 subbasin for analysis and modeling. The Sufi-2 algorithm was used for validation and calibration. The data was divided into two halves of five years each. First half was used for calibration and second half foe validation of model.The results revealed that more than half of the annual precipitation Water is lost in evapotranspiration and runoff. Sediment yield of various soil erosion-prone areas was estimated. The results from modeling were further used to propose and model multiple water conservation and Sediment filtration basin structures in the flood and soil erosion impacted areas This study also revealed that how SWAT model is valid to be used in Hydrological and soil erosion Modeling. These results can be further implemented for water conservation structure, drainage management of Varanasi
