“…The NS tectonic events (normal fault) are identified on the sandstone layer (Fig. 3) [19]. Several formations accumulate at the study site, namely a fractured and diaclase massive sandstone formation of Aquitanian age, overlaying a clay formation; these latter are distinguished by Sub-Numidian clay of the Upper Oligocene age.…”

Purpose. The research purpose is to apply an original combined approach to the study of landslide occurrence in the Tarzoust region, based on geophysical approaches. This is extremely important because landslides damage roads and buildings in many parts of North Africa, especially in the city of Tarzoust, NE Algeria. Significant slope failures have resulted in serious disasters in the region. Methods. In this study we use Vertical Electric Soundings (VES) and Seismic Refraction Method (SRM) for underground exploration, as well as Electrical Resistivity Tomography (ERT) to support the latter two methods. Findings. The clayey nature of the terrain is confirmed, very often covered by a mantle of superficial colluvium formations. The depth of the bedrock and shear surface has been precisely determined. The ERT reveals that the terrain has already experienced instability in the past. Originality. The originality of this study is in the combination of data from various sources and different approaches for the purpose of planning the deployment and use of land. Practical implications. Our approach has proven that the combination of geological and geotechnical data with geophysical deterministic methods can help engineers and decision-makers in land management. Our recommendations consist of topographic, inclinometric and piezometric monitoring for slip development and the effectiveness of reinforcement measures for new housing, and equipment programs for regional planning.

“…The Gadaïne-Ain Yaghout region is characterized by a semiarid climate with an average annual rainfall of 338 mm and an average temperature of 15°C. The runoff, estimated by the empirical formula of Tixeront and Berkaloff, benefits from only 5.3% of precipitation, while infiltration is only 1.06% [33]. There are two levels of aquifers; one shallowly is characterized by heterogeneous MPQ formations of lacustrine limestone, alluvium and clays facies.…”

Purpose. Several natural and anthropogenic factors control the hydro-geochemical behavior of groundwater. These factors influence on the quality, even the suitability of this resource for drinking. The main purpose of our study is the application of multivariate statistical methods to compile the mechanisms of mineralization acquisition in confined aquifers. Methods. The adopted method measures the chemical evolution of Ca+2, Mg+2, Na+, K+, HCO-3, Cl-, SO4-2, NO-3, NO-2, NH+4, and PO4-3 using an atomic-absorption spectrometer. The content of nitrogen and dissolved oxygen is measured using a spectrophotometer. Temperature (T°), electrical conductivity (EC), pH and dissolved oxygen are determined using a multi-parameter system. Findings. The main results show that 28 water samples from the Mio-Plio-Quaternary aquifer of the Gadaïne-Ain Yaghout plain have chemical facies of chloride, sulfate-calcium and chloride-magnesium types. Originality. The originality of the study is in the demonstration that water acquires its carbonate mineralization at the supply limits. Whereas it acquires its chloride, sodium and sulfate mineralization in contact with terrigenous saliferous formations, as well as in its interaction with the salt chotts formations. The results show a significant variation in the concentrations of chemical elements, in some cases exceeding drinkability standards. Mineralization is mainly caused by the dissolution of evaporitic minerals such as gypsum, halite and epsomite. Practical implications. The practical implications of this study could be resumed in terms of the convenience of multiva-riate statistical evaluation of complex physical-chemical databases in identifying pollution sources and understanding temporal variations for effective groundwater quality management in semiarid regions.
