Read Full License Page 1/20 Abstract Dams are critical to agriculture, industry, and the needs of humans and wildlife. This study evaluates the water quality of the Ghrib dam in north west of Algeria, using Irrigation Water Quality Index (IWQI), sodium absorption rates (SAR) and multivariate statistical methods (Clustering and principal component − analysis). The study concerns the analysis of physical and chemical parameters (pH, EC, O2, TUR, Ca, Mg, HCO3, Na, K, BOD, DCO, Cl , PO4, SO3. NH4 et NO3) which were measured at twelve selected points along the dam over 8 periods (dry and wet periods) using standard methods. Irrigation Water Quality Index values in the dam were found to be between 41 and 59, according to classications for different water uses, values below 60 indicate that water is of poor quality for irrigation and treatment is recommended to make dam water more suitable for irrigation.

  • L'acceptabilite Sociale Des Projets Miniers En Algerie
    European Scientific Journal January 2015 edition vol.11, No.3 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 L’ACCEPTABILITE SOCIALE DES PROJETS MINIERS EN ALGERIE: CAS DE AIN DEFLA ET BEJAIA Dr. Madani Azzeddine Maitre de conférences en géographie et Aménagement du territoire Faculté des sciences sociales et humaines Université Djilali Bounaama Khemis Miliana - Algérie Abstract The social acceptability of mining projects in Algeria cases: Ain Defla and Bejaia The acceptability of some mining projects causes environmental problems, to the populations, despite the existence of laws to supervise the investment. In this article we try to explore all the required steps to obtain the mining permit. And we will see the content of the necessary studies for such authorization and the measures to be taken in such projects to have the opinion of the population in terms of the acceptability activity. Examples of mining projects having implementation and operational difficulties in Ain Defla, west of Alger, and Bejaia, east of Alger will be also presented in order to see the extent of the impact and measures taken to highlight the acceptability or rejection by the population. Finally solutions will be presented for each step in order to get the mining authorization, and to obtain acceptability and avoid refusal, which in some cases causes huge financial losses. Keywords: Social acceptability, mining, refusal, Algeria, Bejaia, Ain Defla Résumé : L’activité minière cause parfois des problèmes d’ordre environnemental aux populations et influe également sur leurs comportements vis-à-vis de l’acceptabilité de l’activité, laquelle risque d’être interrompue , suite aux mouvements de protestation des riverains et aux différentes autres actions visant l’annulation du projet minier ; et ce en dépit de la présence d’une batterie de lois permettant de bien encadrer l’investissement dans ce secteur.

  • Contribution of Hydrogeochemical and Isotopic Tools to the Management of Upper and Middle Cheliff Aquifers
    Journal of Earth Science, Vol. 31, No. 5, p. 993–1006, October 2020 ISSN 1674-487X Printed in China https://doi.org/10.1007/s12583-020-1293-y Contribution of Hydrogeochemical and Isotopic Tools to the Management of Upper and Middle Cheliff Aquifers Madene Elaid , Meddi Hind *, Boufekane Abdelmadjid, Meddi Mohamed National Higher School for Hydraulics, LGEE-ENSH Blida, Algeria Madene Elaid: https://orcid.org/0000-0002-7860-9188; Meddi Hind: https://orcid.org/0000-0001-6592-304X ABSTRACT: In the alluvial aquifers of Upper and Middle Cheliff (North-West Algeria), the groundwater quality is deteriorating. The objective of this study was to characterize the physical and chemical prop- erties of these aquifers; and to evaluate the groundwater quality and its appropriateness for drinking and agricultural use. An investigation was carried out by estimating of the physiochemical parameters (Ca2+, 2+ + + - 2- - - - Mg , Na , K , Cl , SO4 , HCO3, NO3, Br and TDS) to identify the chemical characteristics of groundwater. Morever, the isotopic composition was examined to identify the sources of recharge of these aquifers. The groundwater geochemistry for the high water level (May, 2012 and June, 2017) and low water level (No- vember, 2012 and October, 2017) was studied. Accordingly, water samples from 39 water sampling points were collected (October, 2017 and June, 2018), for the purpose of analyzing stable isotopes (18O, 2H). The results show that the groundwater is mainly characterized by Ca-Cl and Na-Cl type. The chemical quality of the water is from fair to poor with the presence of nitrates used in agricultural and urban discharge.

  • Le Diktat Des Gourdins
    L’Algérie profonde / Actualités STATIONNEMENT À AÏN DEFLA Le diktat des gourdins Cette nouvelle activité s’exerce au vu et au su des autorités et s’assimile beaucoup plus à une arnaque qui tend à se généraliser. On les reconnaît à leurs bâtons appelés localement “kalbouza”, à leurs gourdins ou à des cartes façonnées bizarrement accolées à leurs poitrines. “Ils” sont ces dizaines de jeunes qui ont squatté les artères des principales villes de Aïn Defla, telles que Khemis Miliana, Djendel, Miliana, El Attaf… Les abords des marchés et des administrations, lieux très prisés par ces jeunes, sont devenus des no man’s land, c’est-à-dire la propriété de ces jeunes autoproclamés en gardiens de trottoirs, ordonnant à tout automobiliste qui ose se garer dans leur espace de débourser entre 20 et 30 DA. Les autorités concernées se disent satisfaites de cette opération qui a généré des postes d’emploi. De nos jours, garer pour acheter un journal, prendre un café, acheter du pain ou des gâteaux chez le pâtissier du coin… est suivi d’une obligation de payer cette stupide “taxe” sous l’œil inquisiteur d’un jeune brandissant son “redoutable arme” en guise de dissuasion. Dans le cas où un usager refuse de payer, il est comme pris en défaut, insulté… Dans d’autres cas, la voiture est soumise à des rayures. Nous avons été témoins d’une situation où un automobiliste, qui a refusé de payer au motif qu’il avait laissé son fils âgé de 15 ans dans le véhicule et qu’il avait juste pris le temps d’acheter du pain, a reçu des crachats et des injures, d’où une bagarre qui a presque dégénéré.

    ÉTUDE DE LA QUALITÉ DES EAUX AU NORD-OUEST DE L’ALGÉRIE (Cas du bassin de Haut Cheliff) * TOUHARI FADHILA ** École Nationale Supérieure d’Hydraulique Blida - ALGÉRIE Résumé Les eaux superficielles et souterraines sont des ressources importantes et essentielles dans de nombreux pays, et jouent souvent un rôle essentiel dans l'approvisionnement en eau à la fois pour la consommation et l'irrigation. Durant les dernières décennies, la demande en eau a considérablement augmenté, en particulier dans les pays en développement, sous l’effet de la croissance de la population, l'amélioration du niveau de vie, le développement de l'industrie et de l'agriculture et à l'urbanisation. Cela a conduit à des pressions croissantes sur les ressources en eaux. Les prélèvements excessifs de l'eau souterraine au cours des dernières décennies pour satisfaire ces demandes ont donné lieu à des problèmes graves: diminution du niveau hydrostatique, dégradation de la qualité des eaux souterraines et détérioration des écosystèmes. Il est donc essentiel de quantifier et d’analyser la quantité et la qualité des réserves en eau et de trouver le moyen de gérer cette ressource pour en assurer la durabilité. L’objectif principal recherché dans ce contexte est d’arriver à étudier la qualité des eaux souterraines et superficielles dans la région du Haut Cheliff. Les objectifs de notre étude sont comme suit : . Donner un aperçu sur les paramètres de la qualité et sur la méthodologie d’étude d’une eau souterraine et de surface. Localisation et présentation de la région d’étude et de ses caractéristiques ainsi que l'analyse des conditions climatiques et hydrologiques essentielles.
