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 morhometricanalysis was transformed for a better mitigation option. Analysis of streams order No. 2 displayedsignatures 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 undergonetectonic pressures, being tilted northeast to southwest and suffered severe compression so the drainageshowed 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 activityof KR was a point of unique significance because its future behavior might take a different patterndepending on the changing morphology of the area. The present study was to analyzed morphometricstatus for predicted future behavior of KR drainage system. The data so provided was of immensepractical value to develop a comprehensive strategy for implementation of water resources and sustainable development projects.
