The role of geospatial technologies in measuring morphometric characteristics and their geomor-phological implications for the Al-Kuf Valley watershed, northeastern Libya.

Abstract

This study emphasized the importance of using geospatial techniques, (Geographic Information Systems GIS, and Remote Sensing RS), in measuring the morphometric characteristics and their geomorphological indications for the Kuff Valley Basin and its sub-basins. Our primary objective was to provide a comprehensive database on the morphological, topographic, and river drainage network properties of the basin. A descriptive-analytical approach was used to describe the drainage basin and its river network and to calculate morphometric parameters using Digital Elevation Model (DEM). Additionally, the basin's dimensions and its morphometric characteristics were determined quantitatively. The study concluded that the Al-Kuff Valley basin tends to elongate in its shape, due to the geological structure of the Green Mountain. Furthermore, the homogeneity of geological formations throughout the basin was evident from the similarity of morphological characteristics and drainage networks within the sub-basins; moreover, the hypsometric integration indicated that the basin had reached an advanced stage of its erosion cycle.
