This paper map gully potential in the Federal Capital Territory using using topographic attributes computed from a 30 m Digital Elevation Model(DEM) in a Geographic Information System(GIS). The topographic attributes include slope, aspect, plan form curvature, profile curvature and Up-slope contributing area\citet{RN5771}. From those Compound Topographic Index, stream power index and surface ponding index. The result show that \cite{RN4657}
