	Located in northeast Algeria, the coastal aquifer of the Plain of the El-Nil River constitutes a significant source of groundwater. It contains many municipal and private wells used for several purposes, including agriculture irrigation and drinking water. This paper describes a review of potential anthropogenic sources of groundwater contamination over the Plain of the El-Nil River territory. Different potential sources are identified, including 1) cultivated fields, 2) old private sanitation systems, 3) seawater intrusion, 4) dumpsite, and 5) the contaminated rivers crossing the study area. The multi-sources of contamination in the coastal aquifer of the Plain of the El-Nil River could affect large sectors of the aquifer. However, the existing documentation of groundwater contamination of the Plain of the El-Nil River is still limited. Hence, a hydrogeochemical study, including the analyses of major chemical elements and certain stable isotopes, is proposed as the principal outcome of this site-review paper. If undertaken, this proposed study is expected to provide more accurate information on groundwater contamination and, subsequently, could help decision-makers to prepare a practical plan for protecting the local water resources.

	year = {2021},
	abstract = {
	Located in north-east Algerian, the coastal aquifer of Taleza constitutes a significant source of groundwater. It contains hundreds of private wells installed by the population for several purposes including drinking water. Recently, the groundwater has become quite saline; in order to investigate this issue, hydrochemical and isotopic groundwater characterization is carried out, including the analyses of major elements and water stable isotopes d2H-H2O and d18O-H2O. Results confirmed a saltwater intrusion, and interestingly, the intrusion mechanism appears to be more complex than a direct intrusion from the Mediterranean Sea. During the high-water period, saltwater intrusion may also originate from the two rivers bordering the aquifer, via upstream migration of seawater through the river mouths. The heavier ratios in d2H-H2O and d18O-H2O of surface water collected from the rivers suggest that the Mediterranean Sea water is mixing with rivers water. The present study shows that seawater may exert deleterious impacts on groundwater quality and greatly limit conditions for the sustainable groundwater management.

	Considering three sites under different climate conditions (arid, semi-arid, and subhumid), this study aims to use the vadose-zone water stable isotope profiles to estimate the groundwater recharge rate. High-resolution vertical subsurface soil sampling along the vadose zone of the investigated sites was conducted. The collected samples were analysed to determine their stable isotope ratios (δ2H and δ18O) that were used along with the piston displacement method to estimate recharge. Annual recharge rates of 0.2\% ({\textpm} 0.1\%), 2.5\%, and 18\% of the total annual precipitation were obtained for the arid, semi-arid, and subhumid sites, respectively. Recharge rates at the semi-arid and subhumid sites are comparable to those previously estimated using water balance-based methods. The recharge rate at the arid site is lower than that previously estimated for that site using the water budget-based method, revealing difficulties in applying the piston displacement method under an arid regime.

	Sedimentologic and palaeontological investigation of the Upper Pliocene Slama Formation in the Lower Chelif Basin (NW Algeria) led us to collect important bivalve assemblages for taxonomic and taphonomic purposes. A rather comprehensive inventory list of Upper Pliocene bivalves from northwestern Algeria is now available and consists of 30 species, 17 of which are extinct ones. Four principal taphonomic attributes were analysed: bioerosion, encrustation, fragmentation, and abrasion. Physical and biogenic sedimentary structures are used for palaeoenvironmental interpretations. The taphonomic, sedimentologic and ichnological characteristics of most of the deposits suggests they originated from discontinuous processes of winnowing and bypassing of sediments, probably due to the action of storms in shallow waters, mainly in the shoreface depositional environment. The bivalve assemblage is dominated by disarticulated valves and displays significant taphonomic alteration in the shells. Sclerobionts traces in shells particulary affect the oyster shells. Bioerosion traces are predominately those of clionid sponges (Entobia\&nbsp;isp.), polychaetes (Maeandropolydora\&nbsp;isp. and\&nbsp;Caulostrepsis\&nbsp;isp.), bivalves (Gastrochaenolites\&nbsp;isp.), and of predatory gastropods (Oichnus\&nbsp;isp.). Among the sclerobionts, the identified encrusters were juvenile oyster recruits, barnacles, polychaetes (serpulid tubeworms), bryozoans (Microporella\&nbsp;sp. and\&nbsp;Acanthodesia\&nbsp;sp.), and vermetid gastropods (Petaloconchus intortus).

	abstract = {
	Field observations and sedimentological analyses of alluvial terraces of the O. Gourzi (Batna, NE Algeria) lead us to consider sediments as dominated by clayey and silty-sandy fractions overlain by gravel and calcareous coarser fractions. Moderate CaO 3 contents would have resulted from the dissolution of the nearby carbonate relieves. They are mainly composed of Maastrichtian limestones. The distribution of the mineral fraction led us to identify 07 levels including horizons of coarse fractions alternating with layers rich in sand and silt with a roughly constant clay fraction through the stratigraphic column. Kurtosis values, frequency histograms of a prokurtic type, rarily mesokurtic, mark a constant power mode for the transport agent. Classification indices indicate poorly-to moderately sorted material, indicating a turbiditic depo-sitional environment. Quartz grain nature and mor-phoscopy refer to Miocene sandstones as a potential origin. The ferruginous coating is due to the initiating pedogenesis.

	abstract = {
	On the southwestern Tethyan Margin of Tunisia, the well-known anoxic black shale facies of the Cenomanian-Turonian transition contrasts with oxic fossiliferous carbonates, first characterized here as lateral equivalents. In terms of sequence stratigraphy, the analysis of four wisely sampled sections in Central and Southern Tunisia led to interpret these deposits as a transgressive interval (TST). This interval spans the\&nbsp;Whiteinella archaeocretacea\&nbsp;Zone of foraminifera and is capped with a glauconite-rich highly bioturbated maximum flooding surface (MFS). In the reference section of Oued Bahloul and the Kalaat Senan area of North-Central Tunisia, these deposits overlay a Shelf Margin Wedge made of conglomeratic and bioclastic limestones. In South-Central and Southern Tunisia, the TST is characterized by the onset of oxic facies relaying laminated carbonates with local emergence surfaces. The analysis of both oxic and anoxic facies from the Cenomanian-Turonian transition allows identifying five successive bioevent markers, known elsewhere within the Tethyan domain: the extinction of the foraminifera genus\&nbsp;Rotalipora\&nbsp;(or\&nbsp;Thomasinella), the\&nbsp;Heterohelix\&nbsp;shift, the\&nbsp;Whiteinella\&nbsp;proliferation, the filament event, and the appearance of\&nbsp;Helvetotruncana helvetica. Among these bioevents, the\&nbsp;Heterohelix\&nbsp;shift coincides with the transgressive surface, while the filament event announces the maximal flooding surface. These Cenomanian-Turonian transition bioevents are of a particular relevance for regional and long-distance high-resolution correlations.

	The authorities of Constantine city have been working on the redevelopment and calibration of the Rhumel and Boumerzoug wadis since 2015. The latter calebrage works caused great damage to the banks, thus affecting the Quaternary geological formations in place (alluvial terraces, flood plains). A multidisciplinary research project based on a geomorphological and sedimentological approach was quickly set up to create a scientific data base before their total destruction and loss of physical traces all along the wadis. The present study focuses on the sedimentological and geochemical analysis of the alluvial deposits of Boumerzoug wadi in order to describe the sediments, to reconstitute their nature, and to interpret both the climatic evolution and the paleo-environments of the region. Sedimentological and geochemical results confirm the succession of deposition cycles linked to progressive climate change.

	There are several springs in the {\textquotedblleft}Aures{\textquotedblright}. They represent an opportunity for mountain populations where connection to the drinking water is difficult. They are used for human consumption, but mostly for agriculture. In this paper we try to classify about twenty perennial springs and identify the origin of the mineralisation by linking each class to a lithological context. These sources belong to several chemical groups whose apparent type do not necessarily reflect the lithological composition of the corresponding aquifers. Thus, a carbonated water passing through evaporitic formations can acquire a new facies, which further complicates the interpretations. The combination of thermodynamic simulation, statistics and hydrochemistry has given satisfactory results on the chemical identity of these waters. There are, in fact, two groups : one of the carbonated waters ; dominant with 63\% of samples. The other gypsum with 37\% of the samples checked. The rHCO3/rSO4 ratio often gives values superior than 1 which can reach the threshold of 5. The results indicate that : Ca, SO4, HCO3 and Mg control the mineralisation of the water. The phenomena that generated these two groups are multiple and mainly concern the lithological composition of aquifers as well as the mechanisms of mineralisation acquisition during the underground journey before reaching the surface.

	abstract = {
	This article focuses on a type of habitat that existed in the Roman territories in North Africa and assumes that the domestic architecture of the domus is a reflection of the collective identity of culture buried for millennia and considers that house can be a carrier of cultural information in its spatial configuration. Space syntax, through its configurational analysis techniques, allows establishing a qualitative and quantitative analysis by reconstructing the ancestral way of life and the interactions between inhabitants and strangers. We here present and discusse the results of the syntactic analyzes applied to a set of large Roman-African residences or domus in the Roman site of Djemila (cuicul) in Algeria. Topics covered include the spatial organization of the domus and the potential for integration and control of shared activity areas within the residence, with an assessment of its relationship with human use of space and functioning of the domus with the public space through its permeability. It appears that the spatial and formal models created through buildings and the way they are connected and sequenced correspond to codes that govern the activities that take place there, those that need to be separated, and which categories of people have access to them. The domus is structured by the introduction of a multitude of transitional spaces which had two major effects: creating a hierarchy from the outside world to the interior of the building and inducing movement by creating circulation alternatives and help separate areas of unrelated function and areas dedicated to a specific function.

	The Mio-Plio-Quaternary groundwater of Mchira-Teleghma suffers from an increasing rate of salinity especially in the northwestern part. To identify the reason for the water{\textquoteright}s salinity and its aptitude for irrigation, physico-chemical analyses of 20 water samples, which were based on the different physical and chemical parameters (electric conductivity EC, pH, Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42-, NO3-\&nbsp;and Sr2+), were carried out during the period of October 2015. This study showed disquieting anomalies of electric conductivity that reached the value of 4376.14 {\textmu}S cm-1. The statistical analyses, the multivariate statistics: the principal component analysis, Q-mode cluster analyses, Sr2+/Ca2+\&nbsp;ratio and water type showed that the hydrochemistry of Mchira-Teleghma groundwater is controlled by the dissolution of carbonate rocks and the leaching of evaporite processes, which proved that these anomalies of the MPQ groundwater{\textquoteright}s salinity of Mchira-Teleghma are mainly determined by the leaching of Triassic gypsum formations process. This hydrogeochemical process generates an unsuitable quality of water based on Wilcox{\textquoteright}s and Water Quality Index{\textquoteright}s methods, whereas Richard{\textquoteright}s method classifies all water samples to C3S1 and C4S1 classes as they are recommended to be used with salt-tolerant species in well-drained and leached soils.

	Stratigraphic, sedimentological and magnetic study was performed on alluvial terraces, rich in archaeological tools, the region of OUM ALI, in north-eastern Algeria. The sedimentological points of view, the sediments are dominated by the sand fraction followed by the silt fraction; moderate concentrations of CaCO3 are the result of the dissolution of the surrounding limestone reliefs (Maastrichtian limestone). The morphoscopic observation of quartz grains with a dissecting microscope allows us to offer more or less significant changes, since they are often dull or sub-blunted. The results of the magnetic survey are consistent with those of the sedimentological study. The values of magnetic susceptibility are strong in the middle part of the stratigraphic section (just above the archaeological level) and decrease slightly at the top. Lower values are stored in the lower part. The dependence of frequency values of magnetic susceptibility (fd) are strong throughout the stratigraphic section and show the presence of a mixture of single-domain grain size (R), pseudo-single domain (PMD) and superparamagnetic (SP) (with a predominance of SP grains). The high concentration of SP grain size reveals the presence of significant soil formation during the implementation of the sediment

	abstract = {
	The Bouteldja coastal aquifer is one of the most important groundwater resources in North eastern of Algeria. The region is under a sub-humid climate with an average rainfall of 600-880 mm/y. The unconfined aquifer is constituted of Quaternary sands formations. The hydrogeological characteristics were determined based on previous reports. A very important inflow recharges the sandy aquifer in the Southeastern boundary, in relation to a fault network system linking the aquifer and the Obeira Lake area. Another inflow is observed at the Southern boundary in relation to the exchanges with the alluvial aquifer of Bouteldja. The purpose of the present study is to provide an initial assessment of the groundwater flow and water budget of this aquifer. To achieve this goal, a one-layer groundwater flow numerical model was developed using the MODFLOW-2005 code and the FREEWAT software, using the available data. The model was run in steady state conditions. Calibration was achieved using the piezometric measurements of May 2018 as calibration target. After several trials of manual calibrations, the model successfully simulated the groundwater flows directions and heads. Calibration efforts lead to an acceptable concordance (for the purpose of this study) between the estimated and calculated hydraulic conductivity and piezometric heads, except at the Eastern border. The analyses of the simulated inflow budget shows that aside the rainfall infiltration, exchanges with surface water bodies, the adjoining alluvial aquifer and the fault system provide a relevant amount of water. This significant recharge needs additional investigations. This numerical modeling exercise using MODFLOW, the FREEWAT software and GIS reached the objective of a preliminary description of the groundwater flow and it represents an acceptable starting point for more thorough hydrodynamic characterization of the Bouteldja coastal aquifer.
