Les premières recherches scientifiques menées sur les eaux thermales restent toujours d’actualité et présentent un intérêt indéniable à plus d’un titre. En effet ces études basées sur des apports scientifiques spécialisés, ont permis de comprendre le phénomène du thermalisme (qui a été jusqu’a un passé récent considéré par la population comme phénomène surnaturel) et de définir l’origine des eaux dites thermales ainsi que leurs zones d’alimentation et leurs processus d’acquisition de la température et de la minéralité. A signaler que la région d’étude a fait l’objet d’études géologiques par J.M Vila (1980) dans sa thèse de doctorat d’état “La chaine alpine d’Algérie orientale et les confins algéro-tunisiens”, où il a attribué le caractère d’allochtonie. Nous avons pensé alors qu’une étude des sources thermales de la région de Sétif pourra étayer les résultats de la géophysique et infirmer ou confirmer le caractère d’allochtonie attribué à cet ensemble. A partir de cela, nous allons essayer de mieux comprendre l’origine des eaux dites thermominérales (Froides et chaudes) ainsi que leurs zones d’alimentation et leurs processus d’acquisition de la température et de la minéralité et d’optimiser l'interprétation des analyses physico-chimiques en utilisant des moyens d’investigation appropriés. Le programme d’action pour la réalisation de ce travail doit répondre aux préoccupations suivantes : -Quel est l’état actuel de la qualité chimique des eaux souterraines de la région étudiée -Quels sont les mécanismes physico-chimiques régissant l’évolution des éléments chimiques dans le temps et dans l’espace (processus d’acquisition de la température et de la minéralité)? -Quels sont les processus d’acquisition des températures en profondeur des différents points d’eau chaude en utilisant des géothermomètres chimiques, comme indicateurs de la thermalité des gisements d’eaux. Afin de répondre à ces préoccupations, nous allons adopter la méthodologie suivante : -Etude du cadre naturel et hydrodynamique en relation avec le chimisme du milieu -Etude des paramètres physiques et chimiques de l'eau. -Etude des dépendances et relations entre les divers paramètres physico-chimiques de l'eau. -Etude des mécanismes d'acquisition de la température et de la minéralisation des eaux thermales et leurs origines. Pour concrétiser ce programme de travail, un suivi saisonnier des mesures physicochimiques sera effectué sur le terrain ainsi que des prélèvements d’échantillons d’eaux destinés aux analyses chimiques en éléments majeurs, mineurs. L’analyse des résultats ainsi obtenus sera développée à travers les deux parties constituant cette thèse. Première partie CHAPITRE I : Synthèse géologique de l’aire d’étude Elle reste d’une grande importance, dans le domaine du thermalisme nous décrirons les limites géographiques de la région de Sétif et nous examinerons ensuite la géologie et l’hydrogéologie qui portera sur l’étude des principales phases tectoniques, et plus particulièrement le système de la fracturation permettant l’émergence des eaux chaudes ; ainsi que la définition des différents aquifères dans le contexte lithostratigraphique, structural, géophysique et hydrogéologique. CHAPITRE II : hydroclimatologie Elle a pour objet d’étudier les facteurs importants comme la température de l’air pour définir les limites de la thermalité de la région et les précipitations qui conditionnent le bilan hydrologique et la recharge des aquifères. Elle permettra également la classification de la zone concernée sur la base d’indices climatiques et d’établir les principaux éléments du bilan hydrique qui est d’une importance capitale Deuxième partie CHAPITRE I : hydrochimie Cette partie essentielle dans notre travail de recherches, reposera sur le traitement des données des différentes analyses chimiques aussi bien les éléments majeurs que mineurs (fer, manganèse fluor, iode etc...) et la relation existante entre eux. En particulier la teneur en fer dans les eaux de Hammam Guergour. L’interprétation et l’exploitation de ces analyses permettront d’aboutir aux origines géologiques des eaux thermominérales (froides et chaudes), mais aussi d'avoir une idée sur la nature des formations lithologiques traversées par ces eaux et leur dynamique. CHAPITRE II : Géothermométrie Dans ce chapitre nous tenterons d’estimer les températures des eaux en profondeur des différentes sources thermales en utilisant divers géothermomètres chimiques, comme indicateurs des températures minimales et maximales au droit de l’aquifère. Sachant que la plupart des méthodes utilisées reposent sur les teneurs des eaux de certains éléments caractéristiques tels que : silice, calcium, sodium, potassium et carbonates</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">ATHAMENA Ali</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Flux azoté : origine et devenir dans les eaux souterraines, cas de la région de Zana-est Algérien</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://docplayer.fr/66130950-Flux-azote-dans-les-eaux-souterraines-origine-et-devenir-cas-de-la-plaine-de-zana-est-algerien.html</style></url></web-urls></urls><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;span style=&quot;left:153.44px;top:886.724px;16.6px;sans-serif;transform:scaleX(0.930848);&quot;&gt;Nous avons essayé, par ce travail, d’apporter &lt;/span&gt;&lt;span style=&quot;left:461.683px;top:886.724px;16.6px;sans-serif;transform:scaleX(0.925995);&quot;&gt;une contribution à l’étudier les aquifères de la plaine de Zana, et &lt;/span&gt;&lt;span style=&quot;left:94.4px;top:905.724px;16.6px;sans-serif;transform:scaleX(0.930534);&quot;&gt;d’évaluer les risques de la pollution liée au flux azoté.&lt;/span&gt;&lt;span style=&quot;left:461.283px;top:905.726px;16.6px;sans-serif;transform:scaleX(0.916208);&quot;&gt;La plaine de Zana fait partie du bassin versant des hauts plateaux &lt;/span&gt;&lt;span style=&quot;left:94.4px;top:924.926px;16.6px;sans-serif;transform:scaleX(0.881629);&quot;&gt;constantinois et plus précisément du sous bassin versant Merdj&lt;/span&gt;&lt;span style=&quot;left:534.483px;top:924.924px;16.6px;sans-serif;transform:scaleX(0.993349);&quot;&gt;a Zana, qui s’étend sur une superficie de 369 Km² &lt;/span&gt;&lt;span style=&quot;left:94.4px;top:944.126px;16.6px;sans-serif;transform:scaleX(0.937879);&quot;&gt;environ.&lt;/span&gt;&lt;span style=&quot;left:154.24px;top:944.124px;16.6px;sans-serif;transform:scaleX(0.916627);&quot;&gt;L’étude de la géologie en association avec les données de la géophysique &lt;/span&gt;&lt;span style=&quot;left:653.917px;top:944.124px;16.6px;sans-serif;transform:scaleX(0.924105);&quot;&gt;met en évidence l’existence de deux &lt;/span&gt;&lt;span style=&quot;left:94.4px;top:963.324px;16.6px;sans-serif;transform:scaleX(0.930902);&quot;&gt;formations.

Les structures sédimentaires observées sont principalement des zones d'érosion, des zones inondables, des figures en biseau et des variations d'épaisseur associées à des joints de stratification. Du point de vue sédimentologique, les sédiments sont dominés par des fractions argilo-limono-sableuses, suivies par des fractions de gravier et de cailloux. Les teneurs modérées en CaCO3 résultent de la dissolution des reliefs calcaires à proximité (calcaire crétacé) associée à l'augmentation de la température et l'humidité du milieu. L'observation morphoscopique de grains de quartz avec une loupe binoculaire permet d'offrir une évolution plus ou moins importante, car ils sont souvent émoussés ou sous-arrondis. L'étude sédimentologique a été réalisée sur 16 échantillons prélevés systématiquement du haut vers le bas de la coupe stratigraphique. L'examen de la taille brute de la fraction inférieure à 2 mm a permis d'individualiser 03 niveaux dans des couches sédimentaires, certaines fractions grossières riches (gravier, cailloux et blocs) alternant avec des couches riches en sable et en limon. Le pourcentage de fraction d'argile est dominant et reste pratiquement constant presque tout au long de la section stratigraphique.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">DJAIZ Fouad</style></author><author><style face="normal" font="default" size="100%">Defaflia Nabil</style></author><author><style face="normal" font="default" size="100%">Lamouri Bachir</style></author><author><style face="normal" font="default" size="100%">Boushaba Abdellah</style></author><author><style face="normal" font="default" size="100%">Chairat.

For such a project, the feasibility study for a given area is fundamental before the establishment of any related applied research works. This paper is of a socio-economic relevance for the Timgad region (NE Algeria) as the presented results consist of a contribution of both socio-economic operators and policy makers. In the study area, water resources are closely related to the regional geology and the main objectives of the establishment of the Foum-Toub hill reservoir is to promote the irrigation of its plain, regulate the flow of the Foum-Toub creek and minimize the silting of the Koudiet Lemdaour dam. The selected sites for the construction of this work are characterized by an impermeable bedrock. Loose material, favorable to serve as borrow areas, can be supplied from the surrounding depressions where sandstone can also be used for the dike construction.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fouad Djaiz</style></author><author><style face="normal" font="default" size="100%">Defaflia Nabil</style></author><author><style face="normal" font="default" size="100%">Bachir Lamouri</style></author><author><style face="normal" font="default" size="100%">Boushaba Abdellah</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Quaternary fluviatile terraces of the Oued El Gourzi (Batna, NE Algeria): sedimentology and characteristics of the depositional</style></title><secondary-title><style face="normal" font="default" size="100%">Advances in Science, Technology &amp; Innovation </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://link.springer.com/chapter/10.1007/978-3-030-01452-0_79</style></url></web-urls></urls><pages><style face="normal" font="default" size="100%">pp 331-334 </style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">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&lt;sub&gt;3&lt;/sub&gt; 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 depositional environment. Quartz grain nature and morphoscopy refer to Miocene sandstones as a potential origin. The ferruginous coating is due to the initiating pedogenesis.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Slami Rafika</style></author><author><style face="normal" font="default" size="100%">Salmi Laouar Sihem</style></author><author><style face="normal" font="default" size="100%">Bruno Ferré</style></author><author><style face="normal" font="default" size="100%">Riadh Aouissi</style></author><author><style face="normal" font="default" size="100%">Fatiha Kechid-Benkherouf</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Biostratigraphie, Géochimie et réponse des composantes microfauniques aux variations nvironnementales au passage Cénomanien-Turonien à Thniet El Manchar (Monts de Belezma, Batna, NE Algérie)</style></title><secondary-title><style face="normal" font="default" size="100%">Estudios Geológicos intitulé </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/326130603_Biostratigraphie_geochimie_et_reponse_des_composantes_microfauniques_aux_variations_environnementales_au_passage_Cenomanien-Turonien_a_Theniet_El_Manchar_Monts_de_Bellezma_Batna_NE_Algerie</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">74</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">[fr] La présente étude livre une analyse biostratigraphique et géochimique des dépôts cénomano-turoniens de la région Thénièt El Manchar, située dans les Monts de Bellezma-Batna, et leur évolution verticale. Une coupe (TM), épaisse de 180 m, est décrite dans ce secteur. Elle correspond à la Formation des Marnes de Smail, subdivisée en quatre unités litho-stratigraphiques (IA, IB, IC, ID), datée du Cénomanien grâce à la présence d’ammonites et de corail, et à la base de la Formation des Dolomies de l’Oued Skhoun (unité, IIA), datée de la base du Turonien au moyen de foraminifères planctoniques. L’analyse qualitative et quantitative des foraminifères (planctoniques et/ou benthiques), des ostracodes et des marqueurs géochimiques, permet de reconstituer l’évolution du paléo-environnement et les variations paléo-bathymétriques au cours de l’intervalle stratigraphique concerné. Ainsi, les unités IA-IB-IC et la partie inférieure de l’unité ID (Cénomanien) sont dominées par des associations de foraminifères benthiques agglutinés et des carapaces entières d’ostracodes, témoignant d’un milieu de plate-forme et d’un faible hydrodynamisme. Dans ces dépôts, les associations montrent une diversité spécifique faible à moyenne et une abondance plus ou moins élevée, témoignant de conditions trophiques et d’oxygénation considérées comme normales. Les derniers termes de l’unité ID (sommet du Cénomanien) et l’unité IIA (base du Turonien) marquent, quant à eux, une évolution vers des conditions plus profondes, comme le montre la succession standard des événements déjà reconnus en Afrique du nord, à savoir: l’abondance de foraminifères planctoniques, la présence de ‘filaments’ et une réduction drastique de la faune d’ostracodes. En outre, les courbes isotopiques du carbone (δ13C) et de l’oxygène (δ18O) des carbonates mettent en évidence des anomalies isotopiques relatives aux modifications paléo-environnementales. Les données du δ13C et celles du COT indiquent une productivité primaire faible. Les données du δ18O, quant à elles, indiquent une augmentation des paléo-températures, cause principale du déclenchement de l’EAO 2. Ces interprétations paléo-environnementales s’accordent avec les données connues du contexte paléogéographique régional et mettent en exergue les spécificités téthysiennes.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio"

The basin is an asymmetrical syncline oriented East-West covering an area of 1000 Km2. The climate is semi-arid (cold winter and hot summer) with average annual rainfall not exceeding 400 mm. Recently, the increasing agricultural activities led to an excessive exploitation of groundwater resources. In order to meet this rising water supply demands, implementing a water resources management policy is a priority which should be based on a basin hydrogeological study. Effectively, the geological and geophysical studies have confirmed the presence of permeable Miocene and Cretaceous formations (sandstone and carbonate); relatively resistant affected by fractures network, which are probably forming a confined aquifers. Indeed, recent wells drilled in the basin center and their boundaries; show that the aquifers are artesian. The sandstone aquifer of the Miocene is the most important, it is characterized by significant thickness which can exceed 200m, its extension as well as its particular corrugated geometry, characterized by a wavy shape, which forming a series of shale-marl&amp;nbsp;filling depressions, influences the groundwater flow, actually, the piezometric surface illustrates groundwater convergent flow oriented to the east, towards Bou el freis, likewise the sandstone aquifer is marked by the presence of a West-East drainage axis which separates the basin northern part characterized by a low reservoirs hydraulic capacity from the southern part distinguished by the groundwater relative abundance. Groundwater is generally easily extracted, except the northern part of the basin where the top shale-marl layer is thickens to over 1000m.</style></abstract><issue><style face="normal" font="default" size="100%">No. 5</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Athamenani Ali</style></author><author><style face="normal" font="default" size="100%">MENANI Mohamed redha</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nitrogen flux and hydrochemical characteristics of the calcareous aquifer of the Zana plain, north east of Algeria, July, ISSN /e- ISSN: 1866-7511 / 1866-7538</style></title><secondary-title><style face="normal" font="default" size="100%">Arabian Journal of Geosciences</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://doi.org/10.1007/s12517-018-3681-5</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Vol 11</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The hydrochemical and multivariate statistical techniques such as the principal component analysis (PCA) and the cluster analysis (CA) were used to identify the hydrochemical processes and their relation with groundwater quality and also to get an insight into the hydrochemical Zana aquifer groundwater chemistry evaluation. Twenty-four samples during the wet season and even during the dry season are analyzed. The Piper diagram showed that water facies are magnesium bicarbonate on the sides of the western reliefs and magnesium chloride-sulfated at the north and the center of the plain. The PCA carried out on three factors revealed that on the factorial design F1-F3, nitrates negatively determine factor 3, indicating the presence of an agriculture pollution. On the factorial design F1-F2, HCO3− positively determine the factor 2, indicating the carbonated origin. However, the CA, based on variables, showed that the waters in the region can be classified into three groups according to flow direction while the CA, based on major ion contents, defined three groups, reflecting the same hydrochemical facies. The first group with dry residue varying between 360 and 1700 mg/l and characterized by Mg2+ and Cl−, HCO3−. Samples of this group are mostly located in the north and northeastern part of the region. The second group with highest dry residue (2080 to 3820 mg/l) characterized by Mg2+ and SO4−, Cl− is located near the Northwestern and western outcrops. The third group coincides with the central part, the lowest of the plain, with heightened dry residue (4140 to 13,950 mg/l), characterized by Mg2+ and SO4−. The hydrochemical study made it possible to allot the evaporitic origin to the elements Na+, Mg2+, K+, Cl−, and SO4−, while for element HCO3−, it results from the carbonated formations. These results showed that the presence of nitrates in the studied area is closely linked to the agricultural activity.</style></abstract><issue><style face="normal" font="default" size="100%">Issue 13</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kechha</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Étude géologique de la plaine Sud Sétifienne par une approche géophysique</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Douaflia Abdelkader</style></author><author><style face="normal" font="default" size="100%">Benour yahia</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Étude géologique de la plaine de Gadaine par une approche géophysique</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Drias Tarek</style></author><author><style face="normal" font="default" size="100%">Fehdi Chemseddine</style></author><author><style face="normal" font="default" size="100%">Belloula Moufida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Hydrochemical Analysis and Evaluation of Groundwater Quality of an Alluvial Aquifer.

Algeria, located southwest of the Souk-ahras Wilaya in eastern Algeria. It is a plain with agricultural vocation which requires for its development more water. Knowing that the rainfall is low (465mm/year) and not enough to meet the needs of farmers, the use of groundwater then becomes the only alternative to fill this lack of resources. Among the aquifers identified in this region is that contained in fissured limestones of lower Maestrichian age. In order to satisfy farmers and citizens in water it is necessary to have a good characterization of this aquifer. The objective of this paper is to improve the knowledge on the morphology and the extension of this aquifer and to locate its roof in space to help operators choose areas favorable to exploitation, so direct them to the nearest areas of the surface thus minimizing the cost of the drilling operation. To achieve this goal, we have exploited by exploiting several tools (geological map, logs of boreholes and geophysics survey), whose combination gave an idea on the geometry of the aquifer as well as the depth of its roof in different regions of the plain and shows by the occasion, the affectation of these limestones by several tectonic accidents generating thus a structure in collapsed blocks from where the very variable depth of the roof of these limestones of a place of the plain to other.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">ATHAMENA Ali</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Contribution of statistical technique in the Characterization hydro-chimical of groundwater, case of the region Zana-Roknia, Eastern Algeria</style></title><secondary-title><style face="normal" font="default" size="100%">13th International Conference on Water Resources organized by Al-Hussein Bin Talal University and the European Organization for Environmental, Water and Desert Research in Antalya, Turkey 25-27 novembre</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><pub-location><style face="normal" font="default" size="100%">Antalya, Turkey </style></pub-location><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">ATHAMENA Ali</style></author><author><style face="normal" font="default" size="100%">MENANI Mohamed redha</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nitrogen flux and hydrochemical characteristics of the calcareous aquifer of the Zana plain, north east of Algeria, July, ISSN /e- ISSN: 1866-7511 / 1866-7538</style></title><secondary-title><style face="normal" font="default" size="100%">Arabian Journal of Geosciences</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://doi.org/10.1007/s12517-018-3681-5</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%"> Vol 11</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The hydrochemical and multivariate statistical techniques such as the principal component analysis (PCA) and the cluster analysis (CA) were used to identify the hydrochemical processes and their relation with groundwater quality and also to get an insight into the hydrochemical Zana aquifer groundwater chemistry evaluation.

It is a plain with agricultural vocation which requires for its development more water. Knowing that the rainfall is low (465mm/year) and not enough to meet the needs of farmers, the use of groundwater then becomes the only alternative to fill this lack of resources. Among the aquifers identified in this region is that contained in fissured limestones of lower Maestrichian age. In order to satisfy farmers and citizens in water it is necessary to have a good characterization of this aquifer. The objective of this paper is to improve the knowledge on the morphology and the extension of this aquifer and to locate its roof in space to help operators choose areas favorable to exploitation, so direct them to the nearest areas of the surface thus minimizing the cost of the drilling operation. To achieve this goal, we have exploited by exploiting several tools (geological map, logs of boreholes and geophysics survey), whose combination gave an idea on the geometry of the aquifer as well as the depth of its roof in different regions of the plain and shows by the occasion, the affectation of these limestones by several tectonic accidents generating thus a structure in collapsed blocks from where the very variable depth of the roof of these limestones of a place of the plain to other.</style></abstract><issue><style face="normal" font="default" size="100%">01</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>5</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">MENANI Mohamed redha</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">La pollution des rejets liquides de la ville de Batna (Algérie).

		Le SASS couvre une superficie d’environ 1&amp;nbsp;000&amp;nbsp;000 km², il est partagé par l’Algérie, la Libye et la Tunisie. Il est situé dans une zone hyper aride avec une recharge actuelle minime mais un grand volume stocké, évalué entre 20&amp;nbsp;000 et 31&amp;nbsp;000 km&lt;sup&gt;3&lt;/sup&gt;.
	&lt;/p&gt;

	&lt;p&gt;
		Depuis 1970 à nos jours, l’exploitation du SASS est passée de 0,6 à plus de 2,5 milliards m3/an., d’où des risques majeurs &amp;nbsp;de salinisation des eaux, de réduction de l’artésianisme, de tarissement des exutoires naturels, de baisse de la piézométrie, d’augmentation des rabattements ou d’interférences des périmètres de captage entre pays…Ce qui menace à terme la durabilité du développement socio-économique engagé dans l’ensemble de la zone.
	&lt;/p&gt;

	&lt;p&gt;
		Pour parer au mieux à ces risques et surtout pour mieux s’en prémunir, un processus de coopération a été initié depuis 1998 sous l’égide de l’observatoire du Sahara septentrional (OSS) en partenariat avec les institutions en charge des ressources en eau dans les 3 pays.
	&lt;/p&gt;

	&lt;p&gt;
		L’importance de cet immense réservoir pour le développement de la zone SASS et la nécessité de sa gestion durable et concertée a amené à une entente pour son étude en plusieurs phases&amp;nbsp;: la caractérisation hydrogéologique du système aquifère et sa modélisation, l’identification des risques environnementaux et l’inclusion de l’aspect socio-économique dans des scénarios de développement.
	&lt;/p&gt;

	&lt;p&gt;
		Les ressources en eau du SASS sont très faiblement renouvelables, environ 1 milliard de m3/an, vis-à-vis des prélèvements actuels estimés à 2,5 milliards de m3/an. La prise en compte de cette donnée a été déterminante pour pousser les scientifiques à établir la meilleure modélisation conceptuelle possible du système qui soit à même de permettre d’envisager différents scénarios d’exploitation de la ressource tout en tenant compte des perspectives de développement socio-économique de chacun des 3 pays.
	&lt;/p&gt;

	&lt;p&gt;
		Les données actuelles, quoique rassurantes, ne signifient pas l’inexistence, à court ou moyen terme, d’un risque de conflit autour de ces eaux transfrontalières. En effet, le problème mérite d’être analysé à travers plusieurs indicateurs qui ont un impact sur ce risque.
	&lt;/p&gt;

	&lt;p&gt;
		L’objectif de cette note est d’évaluer le risque de conflit autour des eaux du SASS à travers un indice global exprimé numériquement sur la base de la combinaison de poids et de cotes de plusieurs indicateurs qui ont, directement ou indirectement, un impact sur le risque de conflit.
	&lt;/p&gt;

	&lt;p&gt;
		L’indice global de risque de conflit obtenu pour le cas du SASS semble refléter correctement la situation qui y prévaut actuellement. La comparaison de ce résultat avec ceux obtenus pour les eaux transfrontalières du bassin du Jourdain (risque élevé) et ceux du système aquifère du Guarani (risque faible), conforte l’échelle des valeurs adoptée dans cette méthode d’indexation numérique.
