Summary, Conclusions, and Suggestions for Further Work

Abstract

This chapter summarizes the importance of the spatially distributed soil erosion modeling carried out in this study. Sustainable use of land depends upon the conservation and potential use of soil and water resources. The assessment of the risk of erosion can be helpful for land evaluation. The present study was undertaken to assess the annual rates of soil erosion from a watershed using distributed information for topography, land use, and soil with RS and GIS techniques and to compare the simulated sediment loss with observed sediment loss. The study was conducted in the Shakkar River watershed. The methodology adopted in this study involves the preparation of thematic maps of USLE factors (R, K, LS, C, and P) which are combined in a GIS environment to assess the annual rates of soil erosion. Finally, the simulated sediment loss values were compared with the observed values. This study also demonstrates the scope for future research in distributed soil erosion modeling.
