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.
