DYNAMIC CHARACTERISTICS AND MORPHOME???? ANALYSIS OF AN ACTIVE KUNHAR RIVER BASIN, NW HIMALAYAS, PAKISTAN

摘要

Kunhar River basin constitutes 154 km northeast to southwest Kaghan Valley (KV) as a part of western terrain of the Nanga Parbat is the most tectonically active orogen.;Due to tectonic activity of the Nan?a Parbat, KV remains under its persistent influence; its eastern side continuous tilted to make a high ridge, the snowy peaks and, lakes, while western.side gets depressed relatively. Due to tectonics, the compressional forces produced serve folding and active thrusts in NEE to SSW direction. Kunhar River is a point of unique significance as its future behavior may take a different pattern depending on changing morphology of the area. Identification of streams order 2 signatures the testimony of lithologic and structural control, knick. points, non symmetrical longitudinal profile, high value of sinuosity ratio, and orientation of lineament pattern describes an implication of Cymatog?ńi? uplift for drainage basin configuration. An uncertain event of tectonic movement during Neogene's, a sign of vertical hosting by regional compression is discussed. Kunhar River drains into the Ma?gla Dam, the second energy producing facility in Pakistan. A detailed morphometric analysis have been undertaken to predict future behavior of Kunhar River so that sustainable evaluation, monitoring and development measures can be taken.
