Abstract

Himalayan mountain belt was created by the Indo–Eurasian collision. The length of this seismically active mountain belt is almost 2500 km. Southern partition of this zone is marked by the main frontal thrust. We computed the isobase, relative relief, incision, vertical dissection and drainage density maps of the study site. Drainage density is inversely proportional to the rest of computed parameters. Drainage density is less where the incision/deep cutting is high. Pezu and north western parts of the study site are observed vulnerable to tectonic activity and high risks. These sites are the adjoining parts of active faults. The rates of morphological changes and the combination of stripping processes are determined through Surface dynamics maps (SDM). Although it is a handy tool used to evaluate erosion conditions of sags or sub basins. Remote sensing and GIS techniques proved efficient for appraisal of thrust in Marwat Kishore and Bhittani ranges.
