	The Mexa and Bougous dams were built to control river floods and supply crop-irrigation and drinking water. This study aimed to characterize the hydrogeochemical state in the region containing the dams, which influences the quality of the waters and thus their suitability for agricultural use, given the extent of the river networks that naturally transport sediments and pollutants into the reservoirs via streams. Thus, some physicochemical and organic parameters, including electrical conductivity, calcium, magnesium, sodium, potassium, chloride, bicarbonate, sulfate, biological oxygen demand, nitrite, ammonium, and phosphate, were used as benchmarks to examine the stiffness of the water pollution. Sampling was carried out during May and September of 2011 and 2012. The obtained results showed that, according to the Stiff diagram, the dominant hydrogeochemical facies is calcium bicarbonate in waters that do not have calcium levels in excess of 3 meq/l and bicarbonate levels in excess of 2.4 meq/l. The organic pollution index disclosed that the waters have evolved from a moderate to a high degree of organic pollution due to the accumulation of pollutants and nutrients from waste disposal and fertilizers. The samples fell into the C2-S1 class in the Richards diagram; this implies that the waters are suitable for plants that are salt tolerant, but that the use of these waters can cause problems for clay soils. However, in the long term, irrigation with the dam waters may pose difficulties for agriculture due to the resulting increase in the electrical conductivity of the soil. This study concludes that water salinity and alkalinity affect crop suitability, meaning that the temporal monitoring of water quality is needed to avoid adverse consequences for crop production.

	abstract = {
	The region of Tadjenanet is in eastern Algeria in the high plains, characterized by a varied age detritus Mio-Plio-Quaternary. Some geological formations can be an important source of groundwater (alluvial sand, shell limestone, gravel). Its location in semi-arid area involves evaporation pronounced even tilt the balance in a chronic deficit, excluding periods characterized by rainfall events. Agriculture in the study area is the first socio-economic activity and the largest consumer of water resources. It is therefore necessary to consider for effective water management. Indeed, the combination of hydrogeological and hydro chemical geological mapping, geophysics, harvested from field data and their interpretations can be an excellent tool for deciding the suitability of water for irrigation. The analysis of the physicochemical data shows an increase in the concentration of nitrates reaching 200 mg {\textperiodcentered} l{\textendash}1, as well as the analysis by the Richards SAR parameter shows that most groundwater samples are generally suitable for agricultural purposes with 33\%, belong characterizing poor quality. Indeed, the groundwater in the region generally requires prior treatment before consumption and use depending on the type of crop. The assessment of the quality of the water in the region and its consequences on the soil and the types of crops has enabled the authorities concerned to manage the water supply adequately to preserve and protect this vital source for the future from any risk of contamination.

	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{\textdegree}), 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 Gada{\"\i}ne-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.

	The landslide studied is located on RN 77 at PK 23+100 in the municipality of Texenna, 25 km southeast of the wilaya of Jijel. The faults observed in the study area are the result of the combination of several factors: the slope of the slope, the lithology of the soil and the strong pluviometry. The project studied consists in the design and analysis of the stability and reinforcement by backfill reinforced with geotextiles. A visual survey was carried out to clarify the probable causes of the impairments, followed by a geological and geotechnical reconnaissance campaign to determine the lithological nature and the physical and mechanical properties of the different formations that make up the soil. The study continued with a backfill reinforced with geotextiles. The analysis of stability and reinforcement was carried out using the finite element method and Plaxis 2D software. According to the results obtained, which give satisfactory values for the coefficient of safety for different combinations of loads, the choice of installing the geotextile wall at the foot of the road is a technical and economic solution aimed at ensuring stability and restoring the collapsed part of the roadway Keywords: Stability; Reinforced embankment; Coefficient of safety.

	abstract = {
	In this study, a new approach integrating a groundwater vulnerability method and a numerical model for predicting groundwater resource sustainability under actual and future conditions of exploitation (2010{\textendash}2030) is proposed in the semi-arid region of the Tebessa-Morsott alluvial aquifer (northeastern Algeria). The groundwater vulnerability method-based DRASTIC model was used to evaluate and delineate the vulnerable areas using a GIS technique. The MODFLOW code, on the other hand, was used to calculate the dynamics of groundwater level under actual and future conditions of exploitation considering two scenarios. The results of the application of the DRASTIC method to the reference year conditions (year 2010) showed that the high and average vulnerability classes covered a wide zone of the study area, about 97\%. These results were validated based on the nitrate concentration values (R2\&nbsp;= 0.955). However, the results for predicting future groundwater vulnerability showed that groundwater vulnerability variation over time (period 2010{\textendash}2030) was closely related to groundwater depth variation caused by the pumping rate, since the decreases in the piezometric level produce a worsening of groundwater vulnerability. To achieve better groundwater management, an experimental site for artificial recharge supplemented by hydro-chemical monitoring of the groundwater could be an effective remediation strategy.

	volume = {851},
	year = {2022},
	abstract = {
	This study focuses on\&nbsp;coastal aquifers\&nbsp;subject to uncontrolled land use development by investigating the combined effects of seawater intrusion and nitrate contamination. The research is undertaken in a Mediterranean coastal agricultural area (Plain of the El-Nil River, Algeria), where water resources are heavily impacted by anthropogenic activities. A multi-tracer approach, integrating hydrogeochemical and isotopic tracers (δ2HH2O, δ18OH2O, δ15NNO3\&nbsp;and δ18ONO3), is combined with a hydrochemical facies evolution diagram, and a Bayesian isotope mixing model (MixSIAR) to assess seawater contamination with its inland intrusion, and distinguish the nitrate sources and their apportionment. Results show that seawater intrusion is circumscribed to the sector neighboring the Mediterranean Sea, with two influencing functions including classic inland intrusion through the aquifer, and upstream seawater impact through the river mouth connected to the Mediterranean Sea. Groundwater and surface water samples reveal nitrate concentrations above the natural baseline threshold, suggesting anthropogenic influence. Results from nitrate\&nbsp;isotopic composition, NO3\&nbsp;and Cl concentrations, and the MixSIAR model show that nitrate concentrations chiefly originate from sewage and manure sources. Nitrate derived from the sewage is related to wastewater discharge, whereas nitrate derived from the manure is attributed to an excessive use of animal manure to fertilise agricultural areas. The dual negative impact of seawater intrusion and nitrate contamination degrades water quality over a large proportion of the study area. The outcomes of this study are expected to contribute to effective and sustainable\&nbsp;water resources management\&nbsp;in the Mediterranean coastal area. Furthermore, this study may improve scientists{\textquoteright} ability to predict the combined effect of various anthropogenic stressors on coastal environments and help decision-makers elsewhere to prepare suitable environmental strategies for other regions currently undergoing an early stage of water resources deterioration.

	The\&nbsp;Cenomanian\&nbsp;{\textquoteleft}Marnes de Smail{\textquoteright} Formation in Djebel Sabaoune (Batna, Algeria) contains many\&nbsp;fossil\&nbsp;ostracods\&nbsp;with 73 species taxa that are identified for the first time from this area. The ostracod assemblages are consistent with the\&nbsp;Cenomanian\&nbsp;age formerly assigned by means of invertebrate macrofossils:\&nbsp;ammonites, corals, bivalves, echinoids and gastropods. The diverse ostracofaunal assemblages allowed us to reconstruct the palaeoenvironmental parameters that prevailed during the Cenomanian. Both qualitative and quantitative analyses of ostracod assemblages, along with foraminiferal associations and\&nbsp;lithofacies, documented progressive environmental change from a relatively deep marine or outer distal platform (at the base of this series) to a middle, inner platform and, finally, to a reefal environment (at the top). The ostracod taxa are mostly\&nbsp;endemic species. However, the occurrences of species already known from North and\&nbsp;West Africa, the Middle East and the Atlantic clearly demonstrate that migrations still occurred during the Cenomanian.

	The Algero-Tunisian confines (Tebessa region) belong to the southern Tethyan domain and the Monts Mellegue. This region is partly composed of Cenomano-Turonian carbonate outcrops; therefore, the investigated sections\&nbsp;highlight the black shale levels reported over a short period, around the Cenomanian-Turonian boundary. The lithostratigraphic study designated a depositional environment that emphasized a relatively deep, calm, and often confined ocean environment significantly shallower on the northern part of the study area. The facies lithology and distribution leads\&nbsp; to underline the pelagic influences during the upper Cretaceous and neritic throughout\&nbsp;the lower Cretaceous period. The\&nbsp;maximum thickness of the Cenomano-Turonian (1000\&nbsp;m) was recorded\&nbsp;in the southern zones and the\&nbsp;minimum (100\&nbsp;m) occurred\&nbsp; further north. This palaeogeographic organization persists\&nbsp;laterally in Tunisia as\&nbsp;the extension of the Constantine mole. The geochemical analyses reveal\&nbsp;that the maturity of the Cenomanian source rock is variable.

	abstract = {
	This study aims at the mineralogical and physicochemical characterization of the clay formations of the Miocene age from the Timgad Basin (Massif of Aur{\`e}s, NE Algeria), in order to evaluate their possible valorization, notably for their potential use in the manufacturing of bricks and ceramic industry. For this purpose, four samples were taken from a clay-dominated formation that outcrops 5\&nbsp;km east of the Timgad city. Each sample was collected, prepared, and analyzed by the appropriate analytical methods of characterization such as X-ray diffraction, X-ray fluorescence, and scanning electron microscopy. Moreover, other complementary analyses are performed in this study such as laser granulometry and geotechnical tests. The results of the different tests revealed that the clay formations of the Timgad Basin are non-refractory clays and characterized by medium plasticity. These clays are constituted of more than 50\% of fine fraction, mainly represented by kaolinite in association with non-negligible proportions of illite, chlorite, mixed-layer clay minerals, and traces of smectite. Besides, this clayey assemblage is accompanied by some proportion of quartz and calcite, as well as traces of hematite, feldspar, and gypsum. In the light of these results and in combination with the particle size distribution, as well as the results of geotechnical tests, it is concluded that the Neogene clays of the Timgad Basin present high limits of Atterberg. Consequently, their use in the field of manufacturing of bricks and terra cotta {\textquoteleft}Terre Cuite{\textquoteright} products is subordinated to a preliminary treatment with addition of a degreasing agent, in the form of coarse sand, in order to improve their plasticity.

	Trace fossils provide detailed palaeoenvironmental and palaeoecological information of both ancient and modern sedimentary systems. During middle Miocene times the Aures Massif located in the northeastern part of Algeria, was affected by, at least, one marine transgression. The latter led to the installation of a carbonate platform, which is placed, for the first time, in a Mediterranean context. In the Rhassira basin, the Middle Miocene marine succession is characterised by carbonate platform deposits dominated by rhodolith beds, typical of those known throughout the Mediterranean area. This succession can be divided into many units separated by discontinuities interpreted here as omission surfaces. The Djebel Arhane section shows two omission surfaces characterised by a pre-omission suite (firmground) represented by Balanoglossites burrows for the first surface and Gastrochaenolites ornatus burrows/borings for the second one, and an omission suite (hardground) as evidenced by the bioerosive structures Trypanites and Caulostrepsis, in both surfaces, respectively. Gastrochaenolites ornatus traces were formed and preserved in firm, compact, semi-lithified and fine-grained substrates (firm- to hardground), indicating the Glossifungites ichnofacies. They show bioglyphs which have been formed during contraction of the posterior adductor muscles. These suggest that their tracemakers were represented by suspension-feeding bivalves, most probably Pholadidae or Mytilidae, which rotated during penetration. The fill of these traces is composed of marine deposits related to a transgressive lag. The omission suite is divided into two ichnocoenoses: (i) pre-lithification burrows/borings, and (ii) post-lithification borings. This is the first report of the ichnotaxon G. ornatus from Algeria.

In the Jebel Kasserou and J. Bou Merzoug study sections, most of the standard Upper Tithonian{\textendash}lowermost Valanginian calpionellid zones and subzones are first identified here. Their limits correspond to main calpionellid bioevents allowing to recognize a new Alpelliptica Subzone of the Calpionella Zone in the Lower{\textendash}Middle Berriasian; subsidiary bioevents being useful to delimit six horizons in the Upper Tithonian Crassicollaria Zone and two others in the Middle Berriasian Elliptica Subzone. All these biostratigraphic units are correlated with their lateral equivalents in other Tethyan sections, mainly from Morocco, Tunisia, SE France, Spain, the Carpathian Ranges and the Balkanides. Chitinoidellid and most of the calpionellid species from Eastern Algeria are first illustrated here. In addition to their easy access and good outcrops, the continuous, complete and thick marine study successions are devoid of strong diagenetic alteration, synsedimentary features and tectonic effects. The {\textquotedblleft}Ravin Bleu{\textquotedblright} site is proposed herein as a potential reference section for the JKB interval in the North Africa Maghrebian Ranges of the SW Tethys Margin.

	In the northeastern Algerian Sahara, the Oued Righ region is one of the most prominent geothermal areas and it is defined by a hot arid climate. Water resources in Oued Righ valley are heterogeneous in terms of geological and environmental conditions; this is marked by multi-layer groundwater system through the formations of the Continental Intercalary aquifer, the Terminal Complex, and the Phreatic water. The Phreatic water is an important aquifer system used for public water supply and irrigation purposes. The main objective of this paper is to study the quality of Phreatic water through, the hydrogeochemistry characteristics in order to investigate how it mineralizes. Thirty water samples were collected in July 2019 and September 2020 and were analyzed for major dissolved chemical components. The water samples are characterized by conductivities ranged from 6360 to 193900 μS/cm (July 2019) and 6890 to 226400 μS/cm (September 2020). The water is mostly of sodium chlorinated, sodium, and magnesium sulfated types. Results of mineral equilibrium modeling showed that the Phreatic waters of Oued Righ are undersaturated with respect to evaporite minerals. Gibbs plot revealed that, the evaporations and crystallization dominance activities and oceanic tides are the primary causes of increased salinity in the Phreatic water of the studied area. The Phreatic water of Oued Righ perceived a change in its chemical characteristics during the tow sampling periods, caused by water-rock interactions and mixing processes.

	Polluted water poses significant health risks when it is part of the water sources used for irrigation, leading to the contamination of soil and plants by various pollutants. This work aims, firstly, to assess the degree of pollution of Wadi El Gourzi water (Batna, Algeria), and then to verify the consequences on their use for the irrigation of market garden plants for everyday consumption (lettuce, cilantro, parsley and spinach), both in the aerial part (stems and leaves) and in the soil where they are grown. This study focuses on trace metals (Cr, Pb, Zn and Cd). Soil pollution was assessed by calculating the soil pollution index (PI), while the uptake of these elements by plants was monitored by the transfer factor (TF). The analyses of the Wadi El Gourzi water with the flame atomic absorption spectrophotometer (FAAS) show a maximum abnormal concentration of Cr (17.37 mg.dm{\textendash}3), Pb (0.71 mg.dm{\textendash}3) and Cd (0.45 mg.dm{\textendash}3). For the analysis of the soils irrigated by these waters, the results of the PI show that the soils used for the cultivation of parsley and lettuce are polluted by several metals (PI \&gt; 1). The concentrations of trace metals elements (TMEs) in the sampled plants show a significant accumulation of Zn, Cd, Pb and Cr by the vegetables (coriander, parsley, spinach and lettuce). These concentrations are above the permitted standards.

	The Teleghma plain is located in northeastern Algeria, in the upper valley of Oued Rhumel. It is characterised by a semi-arid climate with average annual precipitation of 300 mm/ year. The shallow aquifer of Mio-Plio-Quaternary is powered mainly by carbonate formations of the Eocene surrounding the r{\'e}gion. The uncontrolled use of groundwater for irrigation has caused water stress in the area which has threatened the degradation of water quality. On the other hand, the intense use of chemical fertilisers for agriculture aims has caused groundwater pollution by nitrates where concentrations exceeded the standard limit recommended by the world health organisation.

	abstract = {
	Tolga groundwater is one of Biskra{\textquoteright}s most important water supplies for both drinking and agriculture. The purpose of this study is to assess the hydrochemical and isotope (2H and 18O) signature of water in the Tolga area. To evaluate the hydrogeology of groundwater in the Tolga region, a chemical, piezometric, and isotopic research was employed. The results of the Piper diagram revealed that there is just one major hydrochemical facies in the research region, which corresponds to Ca{\textendash}Mg{\textendash}Cl{\textendash}SO4. The piezometry of limestone sheets shows that as one goes westward, the turns become less substantial, with turns about 20 meters and a piezometric level of 140 m. For the rst time, the local meteoric water line (LMWL) was drawn for Complexe Teminal (CT) and Continental Intercalaire (CI) on Tolga groundwater. The Tolga area LMWL refers to the equation δ2H= 7,18 δ18O + 4.17 with R2 about 0.85. CI and CT measurement locations indicate deuterium excess values ranging from 8.35 to 12.57. Indeed, the majority of values were more than 10{\textperthousand} (mean of 10.36 {\textpm} 2.01{\textperthousand}). Furthermore, waters from Eocene have an isotopic composition of-7.57 {\textpm} 0.68{\textperthousand} in δ18O and - 49.04 {\textpm} 4.69{\textperthousand} In δ2H. The results of the sample characterisation analysis show that the majority of the groundwater samples analysed are of the Ca-Mg-SO4 water type. In addition, the intense exploitation aquifer water and the region{\textquoteright}s arid climatic conditions resulted in a large decrease in the piezometric limestone level. Finely, the signature of 2H and 18O data indicate that water comes from local precipitation and recent water, and groundwater recharge is in uenced by quick in ltration.
