ASSESSMENT OF DIVERSE GEO-ENVIRONMENTAL PARAMETERS FOR MITIGATION OF AN UPPER CATCHMENT OF JHELUM RIVER BASIN, NORTH WESTERN HIMALAYAS, PAKISTAN

Abstract

For instituting a useful research cum database, a critical description of morhometric
analysis was transformed for a better mitigation option. Analysis of streams order No. 2 displayed
signatures of lithologic and structural control, knick points, non-symmetrical longitudinal profile, and
high value of sinuosity index (1.75) besides orientation of lineament pattern that had depicted an
interface of Cymatogenic uplift for drainage basin configuration. Notably, Kaghan Valley of the
Kunhar River (KR) originated from shoulder of the Nanga Parbat. Resultantly, valley had undergone
tectonic pressures, being tilted northeast to southwest and suffered severe compression so the drainage
showed zig zag pattern with prominent knick points. The impact of KR was added silted flow into the
Jhelum River that was custodian of Mangla, the country’s hydal power producing facility. The activity
of KR was a point of unique significance because its future behavior might take a different pattern
depending on the changing morphology of the area. The present study was to analyzed morphometric
status for predicted future behavior of KR drainage system. The data so provided was of immense
practical value to develop a comprehensive strategy for implementation of water resources and
sustainable development projects.
