Hydrogeological study of the lower Devonian aquifer in The Illizi region

Abstract

Groundwater is the main source of water in the Algerian desert, the hyper arid climate in Illizi area with low precipitations and very high temperatures is the origin of the scarcity of surface water, hence the need to exploit groundwater. Our work consists in the hydrogeological study of the lower Devonian groundwater in the Illizi region, a land company was carried out to determine the water levels and the flow directions of the lower Devonian aquifer. The realization and study of the piezometric map shows two flow directions N-SE and SE-NW. The hydrochemistry study shows good characteristics and groundwater is composed of two chemical facies that are: Chlorinated calcium facies and Bicarbonate calcium facies...
