Journal ArticleDOI
TL;DR: In this paper, a comprehensive review of various recharges studies in the North Gafsa basin (South Tunisia) is given, which is characterized by a natural groundwater recharge that is deeply affected by the lack of precipitations, and the aim of this study is to determine the recharge potential zones and to quantify (or estimate) the rainfall recharge of the shallow aquifers.

Journal ArticleDOI
TL;DR: In this paper, an integrated application of geochemical modeling and statistical approaches (Principal component analysis and hierarchical cluster analysis) based on a major and trace ions from the Jerba unconfined aquifer was used.

Journal ArticleDOI
TL;DR: In this article, a study was conducted to investigate and document the factors controlling such salinization and their interrelationships in the Dakhla Oasis (Egypt) to accomplish this, 60 groundwater samples and 31 soil samples were collected in February 2014.

Journal ArticleDOI
TL;DR: In this paper, the authors used compromise programming for water quality index in arid/semi-arid regions such as Karaj, Iran, where TOPSIS, Compromise Programing (CP) and Ordered Weighted Averaging (OWA) operators were adopted to alleviate contradictions involving WQI index.

Journal ArticleDOI
TL;DR: In this article, rare earth element (REE) analyses were performed on glauconite-bearing phosphorites from northeastern Algeria, where two localities were investigated: the Djebel El Kouif in the north and the Kef Essenoun in the south.

Journal ArticleDOI
TL;DR: In this paper, an approach based on geostatistic linear ordinary kriging (OK) and Geographical Information System (GIS) techniques to investigate the spatial distribution of alluvial gold content, mineralized and gangue layers thicknesses from 73 pits at the Ngoura-Colomines area with the aim to determine controlling factors for the spatial distributions of mineralization and delineate the most prospective area for primary gold mineralization.

Journal ArticleDOI
