    Etude comparative entre deux sources d’eau Naturelle de la wilaya de Khenchela : Ain Al Karma & Ain Sfa
    (Université Abbes Laghrour -Khenchela-, 2012) LALAOUNA Mehieddine; MERDACI Ilies
    The Wilaya of Khenchela, East Algeria, is one of Wilayate which suffers from a high demand on the water resources in their various localities, because of the importance of this living matter. The choice of this subject consists in determining the physicochemical characteristics of the two sources strongly attended by the population of the wilaya. The first is the source of Ain Al Karma, located at the commune of Khenchela and the second source of Ain Sfa, located at the commune of Tamza. After some visits of the study area, we carried out samplings to analyze. A climatic data gathering (temperatures, precipitations, ETR, ETP, agricultural deficit, Surplus, Infiltration, and Rainout) are carried out to determine the hydrous balance. A specific research is carried out to determine the various geological formations of the zone comprising the two sources. The hydrochimy allowed a classification of water by using diagrams for the classification of waters (Diagramms of Piper, Stabler, Schoeller-Berkaloff Wilcox and Riverside). The interpretation of the various results and diagrams used was done by comparing these results with WHO standards. Climatic configuration and geological formations affect on the quality of the two sources which have a good quality for the human use (potability) and for the irrigation of the arable lands.
