Soil Erosion/Loss of Koshi Basin

Accelerated soil erosion is a common and environmentally destructive consequence of development in the populated trans-boundary Koshi river basin. The objective of this study was to assess assessment of soil erosion pattern and dynamic change trend of spatial distribution in erosion status between 1990 and 2010 and obtained the conservation priority map in the Koshi basin area using GIS and remote sensing. To develop soil erosion pattern revised universal soil loss equation (RUSLE) were adopted in ArcGIS environment where is the rainfall erosivity, soil erodibility, slope length factor, crop management factor and support practice factors were used a primary parameters. This study result the annual total erosion 4,35,996 ton/ha/yr in 2010.

Description: The GeoEye-1 Satellite sensor features the most sophisticated technology ever used in a commercial remote sensing system. This newly developed sensor is optimized for large projects, as it can collect over 350,000 square kilometers of pan-sharpened multispectral satellite imagery every day.
