Soil Erosion Modelling and Contribution of Conservation Practices in Reducing Soil Loss and Transport at Watershed Scale

Soil erosion is a serious problem of land fertility degradation and has become an important environmental issue. Many a complex factors are involved like climate, topography, landuse and these all are responsible for soil erosion hence its estimation is quite tough a task. This study addresses the challenge to predict the soil loss due to soil erosion and simulate BMPs performances in reduction of soil erosion at watershed scale using SWAT. The BMPs were simulated by modifying certain parameters to reflect the impact of the practices on the processes modelled in SWAT. The BMPs were simulated over the SWAT modelled processes, individually and as well as in combination. This study showed that when BMPs are considered an increase in water infiltration and reduction in the sediment yield at the Mohgaon outlet is the result.
