An overview on the development of the irrigation system in the province of Adrar (Algeria) (original) (raw)

Arabian Journal of Geosciences

Abstract

The area of Adrar is characterized by a traditional collecting system which one calls “Foggara it” which is considered the most effective alternative which the man found, in the desert, to solve the water shortage problem. This study aims to present principal geologic, hydrogeological, and hydrochemistry characteristics of the tablecloth of the Continental Guide in the area of Touat. This tablecloth is also called the tablecloth of the Gault. It is contained in the sandy-argillaceous formation of the Lower Cretaceous. From the chemical point of view, this water is very mineral-bearing and excessively hard, with strong contents of chlorides, sulfates, and sodium. The results showed that groundwater of the Adrar region is poor from the point of view of portability and they generally present risks on salinization for the soils. The Foggara is threatened of extinction (degradation, drying up, deterioration of water quality, etc.) because of problems local and regional related mainly on the exploitation and management of water, which requires a better vision for rational management of this resource to ensure sustainable development. For that, several recommendations are proposed.
