Abstract :
Digital Elevation Model (DEM) acquired by Shutter Radar Topographic Mission
(SRTM) is useful to compute Surface Dynamics (SDs) including, Drainage Density
(DD), Topographic Relative Relief (TRR), Iso Base-Levels (IBL) and Topographic
Vertical Dissection (TVD). It provides detailed information about the lithology based on
erosional boundaries as well as delineation of active tectonic scarps. It confers a well-built
connection among diverse stream Strahler ordering and the localized erosive or neotectonics
conditions in an actively deforming topography. These techniques are rapid, proficient, and
consistent to demarcate tectonic control even along or over the similar lithologies. This
investigation appraises the eroding and uplifting landforms along upstream of Mangla
reservoir in lower Jhelum valley. The aim is to delineate margins for lithological demarcation
and to distinguish whether these are affected by neotectonics or not. We noticed unusual localbase-level inconsistency that may be related to the well-known active tectonic expressions.
