ABSTRACT
The Revised Universal Soil Loss Equation (RUSLE) parameters were assessed using Satellite Remote Sensing (RS) and GIS with a view to model soil erosion in Kastina area, Kastina State of Nigeria. Data on parameters such as slope factors, crop cover and management practice support (P) were obtained from Digital Elevation Model (DEM) and Landsat ETM +, 2002 of the area.The estimated potential mean annual soil loss of 17.35 ton/ac/yr based on the refined RUSLE was obtained for the study area. Also, the potential erosion rates from the erosion classes identified ranged from 0.0 to 4185.12 ton/ac/yr. About 65.47% of the study area was under the first class with erosion rates lies between 0.0 and 10 ton/ac/yr.The most severe eroded area with erosion rates between 104.80 and 4,185.12 ton/ac/yr accounted for about 1.86% of the study area.On the whole, this study has demonstrated the significance of Satellite (RS) and GIS technologies in modeling erosion.
