    THE ORIGINALITY OF OASIS OF SAOURA IN SOUTH-WEST OF ALGERIA
    (university of el oued/جامعة الوادي, 2019-01-01) Rezzoug, C; Remini, B
    For centuries the oases of the Saoura continue to manage critical situations of drought and the hostility of the Algerian Sahara through the rational exploitation of water, a rare and precious source of traditional irrigation techniques have proved their efficiency. The use of new groundwater drainage systems of drilling, and the lack of effective management of the Foggaras, has made this system lose its value, deteriorate and let the palm groves disappear. More than 80% of these systems have been abandoned in recent years. With increasing urbanization, population growth, climate change and the uncontrolled proliferation of motor pumps, the level of the water table is lowered and the quality of the water is degraded. The foggaras have gradually been abandoned, which leads to the degradation of the gardens and the old oasis.

    SEAWATER PROBLEM IN THE ALLUVIAL COASTAL AQUIFER OF NADOR, TIPAZA, ALGERIA
    (university of el oued/جامعة الوادي, 2021-09-01) Bouderbala, A; Remini, B; Saaed, H. A; Younsi, A
    This work focuses to the study of the coastal aquifer of of Tipaza in the north of Algeria, for highlights mechanisms of potential seawater intrusion into groundwater. Tipaza aquifer has been overexploited for irrigation and water supply, which caused a negatively impacts on its water quality. To investigate these impacts, many tools have been carried out as: monitoring of piezometric level and physico-chemical analysis of 24 wells from 2008 to 2012 and pumping tests. The piezometric map shows the existence of zero meter level inside the plain; which making this area vulnerable to seawater intrusion, where isovalue curves of some chemical parameters are in increasing towards the sea. Results show also a high concentration gradient of some parameters in the first two kilometers, at 1 mS.cm-1.km-1 for EC and 600 to 900 mg.L-1.km-1 for sodium and chlorides respectively. The hydrochemical study confirme the hypothesis of seawater intrusion in the coastal aquifer of Nador.
