Abstract: Soil is considered as one of the world’s limited, non-renewable resource. Under cropland conditions, it takes between 200 to 1000 years for 2.5cm of top soil to form. Soil is one of the most important natural resources of each country. One of the main and effective parameters in soil erosion is the natural characteristics of the soil which is erodibility. Erodibility is the part and parcel of soil erosion. The objective of this study was to estimate the soil erodibility (K) factor of thirty four soil sample of Sukhna Lake catchment using Geographic Information. The study was carried out through particle size distribution with pipette method and GIS approach using SOI topographical sheets No. H43K13, H43K14 of 2009 scale of 1:50,000 and by using ArcGIS 9.3 software. Soil erodibility (K) factor varies from <0.35 to > 0.65. The area under severe erosion zone were 2023.35 ha, only 54.07 ha and 214.54 ha falls under very low and low erosion zones. Maximum area of erodibility falls under high erosion zone in which 2023.35 ha were estimated. Similarly 1139.81 ha fall under moderate erosion. The analysis shows that catchment is very prone to the soil erosion with an appropriate soil conservation measures, soil erosion may reduce and also provide positive result to the Sukhna Lake. Remote sensing and GIS data is very useful for estimating the soil erosion more easily and accurately within short time duration.
