Abstract: The Potwar plateau was developed in subduction zone of lower Himalayan fold and thrust in the North West region. This study identifies topographic deformation and neotectonics activity using Digital Evaluation Model (DEM). The SRTM DEM having resolution of 90 m analyzes active tectonics in local drainage network. Standard algorithms and geomorphic indices are used to extract isobase maps, concavity, steepness and relative rates of uplift. The steepness index indicates the elevation of Potwar region. The variable rates of uplift, indicates surface deformation in different regions of Potwar plateau. Isobase maps indicate lithological distinctions and structures under the influence of neotectonics using geological maps. Landsat satellite imagery was used to indicate neotectonics activity over the spatial drainage network and streams corresponding to the longitudinal river profile analysis.
