Evaluation of Morphometric Parameters for Identifying groundwater recharge potential zone by GIS application in Kufrah basin SE Libya

Abstract

A number of studies have been done by using various approaches of remote sensing techniques and GIS applications to discover and identify a great aquifer in SE Libya. One of the main goals of these studies was to find out the source water of this aquifer in the Kufrah basin and how it could be recharged. Modern GIS applications were used in the current study for morphometric analysis of the network streams and delineation of Kufrah basin to identifying groundwater recharge zone. The obtained results show a positive linear relation. The results show that the study area is a flat area with low relief topography, low moisture content and high evaporation rate. The drainage pattern of the Kufrah basin is a dendritic pattern with the 7th order of streams. The network streams over a permeable subsurface material, high infiltration capacity with very coarse texture, and low runoff. The Kufrah river can be described as an “Old age” river and drained inland at Al-Jaghbub area.
