    HYDROGEOCHEMICAL MODELING OF GROUNDWATER OF THE QUATERNARY AQUIFER IN MELLAGOU VALLEY -BOUHMAMA- (NORTHEASTERN ALGERIA)

    The use of groundwater in Bouhmama area for drinking and irrigation purposes has increased progressively over the past decade. The water quality of the aquifer has been significantly altered by anthropogenic activity, such as the extensive use of chemical fertilizers. This research intends to enhance our understanding of the hydrogeochemical function of the Mellagou aquifer in the Bouhmama area in northeastern Algeria. It contributes to the identification of the phenomena affecting the mineralization and the mechanisms of salinization of groundwater. A total of 15 groundwater samples were collected during the rainy seasons in 2022 distributed in the study area. In order to performed the results obtained this study used hydrochemical diagram (Piper, Schoeller, Stiff, Stabler, and Wilcox diagrams), thermodynamic models (saturation indexes), and statistical method (PCA). Three chemical facies with a predominance of the calcic bicarbonate facies reflect the influence of intercalations within the bicarbonate sedimentary formations. Groundwater mineralization is mainly governed by the dissolution and the precipitation of minerals (gypsum and halite, calcite and dolomite), Base Exchange, and anthropogenic activities. The results acquired by PCA show that the variables controlling water mineralization are Cl .

    Remote sensing, and (GIS) approach, for morphometric assessment and sub‑watershed prioritization according to soil erosion and groundwater potential in an endorheic semi‑arid area of Algeria
    (Arabian Journal of Geosciences, 2023-06-14) Dali, Naouel; Ziouch,Omar Ramzi; Tarek,Daifallah; Berkani,Cherifa; Hassad,Sara
    The application of remote sensing (RS), and geographical information system (GIS), has emerged as one of the most useful methods for the assessment of drainage assessment and sub-watershed prioritization for soil erosion and groundwater potential of watersheds. The present study is focused on morphometric characterization and prioritization of Constantine’s highland catchment, an endorheic semi-arid basin situated in the east of Algeria. It is subdivided into seven sub-catchments. Using digital elevation model (DEM) and Arc GIS tools showed that all of the sub-catchments except the Gareat El Tarf sub-watershed (07–07) had a good permeability, high iniltration, and high groundwater potential, as the geological structure controls the drainage. Yet, drainage density varies from 0.28 km/km 2 for sub-watershed of Chott Beida (07–01) to 0.41 km/ km 2 for the Gareat El Tarf (07–07) sub-watershed. After prioritization of the sub-watershed for soils and groundwater potential, we conclude that a large part of the sub-catchments in the Constantine’s highlands showed high erosive levels of soil and a low groundwater potential.
