This study aim at performing geomorphological and GIS Analysis to map gully erosion susceptibility in Taraba State. GIS and Remote sensing integrated with Erodibility Variables Soil, Landuse and Erosivity Variables Elevation Aspect, plan Curvature, Stream Power index SPI , Topographic Wetness Index TWI , Length Slope Factor LSF were used in mapping gully erosion susceptibility. All Erosive Variables were automatically derived from SRTM DEM http earthexplorer.usgs.gov and were analyzed using 3D Analyst and Spatial Analyst Extensions of ArcGIS 10.1. The result shows that 2 are of very High Susceptibility, 33 High Susceptibility, 37 Moderate Susceptibility and 28 Low no Susceptibility.
