    Hydrochemistry and isotopic geochemistry contribution to the characterization of the aquifers of the upper Plains of Algeria, case of the basin of Chemora, oriental Algeria
    (Journal of Materials and Environmental Sciences, 2017-05-30) N. Belkoum; B. Houha
    The upper plains of eastern Algeria are bordered to the south by Aures mountains culminating at 2328 m on Chelia moutain. The water springs of Chelia, initially is weakly mineralized, can become salty by interaction with rocks of Chemora basin and successive evaporation. The salt concentrations can increase until the precipitation of evaporates. The main places of the formation of the solid salts are the irrigated agricultural soils, where evaporation reaches or exceeds the inflow of continental water. Chemical water facies evolved from bicarbonate calcium and magnesium to sulphate calcium. The use of chemical and isotopic tools have shown that the origin of waters mineralization is linked to the interactions water-rock that occur along the flow in the reservoir, by dissolution and mineral precipitations , to the cations exchange and the pollution. The isotopic tool has demonstrated that the aquifer recharge is ensured by meteoric little evaporated waters, with altitudinal influence.
