Full textManaged Aquifer Recharge MAR is an emerging sustainable technique used to solve water management problems. MAR presents great interest for karst aquifers, however known to present a high heterogeneity. MAR remains till date marginal in karst aquifers. Accordingly, the present work presents a methodology for Aquifer Rechargeability Assessment in Karst ARAK. The aim of ARAK is to determine the ability of a karst aquifer to be artificially recharged from its surface; and the best sites for implementing the recharge. Based on multi-criteria indexation analysis, ARAK considers 4 criteria: Epikarst, Rock, Infiltration, Karst. The criteria are indexed at each mesh of the 2 D grid domain, from geological and topographic data. ARAK computes the intrinsic rechargeability index, describing the rechargeability of a karst aquifer, on the regional scale, then on the identification of rechargeable sites. Subsequently, a feasibility factor, weighting the techn ical and economic difficulties of a recharge operation, is applied to the selected sites. The methodology, developed to reconcile the problems encountered to identify sites for MAR in karst, provides a useful tool to help water authorities to determine the potential of MAR in karst aquifers. ARAK was applied to Damour site (Lebanon). This coastal aquifer, source of water supply for Beirut, was salinated by its uncontrolled exploitation. A MAR system in Damour region should remediate to it. The four ARAK criteria were indexed and mapped. The final map showed that the aquifer is favorable to a recharge operation, and identified several potential rechargeable sites. However, the feasibility factor indicated that major difficulties hinder the use of infiltration ponds. The solution proposed consists of drilling a horizontal gallery for injecting river water. Water authorities consider that an aquifer recharge project could offer solutions for the shortage in water supply and the sea water intrusion

Full textThe Chaouia coastal aquifer in Morocco is under severe hydrological stress due to over-exploitation. Excessive pumping during the past decades in the Chaouia region has caused a significant lowering of groundwater level. A numerical assessement of seawater intrusion has been achieved applying a 3D variable density groundwater. SEAWAT 2000 computer code was used for simulating the spatial and temporal evolution of hydraulic heads and solute concentrations of groundwater. Sensitivity tests were led to judge the reactivity of the model in relation to the various parameters and constraints. The set of the results allows to have currently at disposal a representative numerical tool of the Chaouia coastal aquifer, usable in view of the qualitative and quantitative preservation of resources in water of this system

Full textCette étude a été réalisée sur l'aquifère profond captif de Camargue dans le cadre de l'ORE RESYST. Cet aquifère présente des salinités élevées atteignant celle de la Méditerranée à proximité de la côte. Deux approches ont été menées conjointement : (i) une étude hydrodynamique en régime permanent et transitoire pour préciser le fonctionnement hydrogéologique de l'aquifère (flux, conditions aux limites, propriétés hydrodynamiques) et (ii) un suivi des traceurs naturels hydrochimiques et isotopiques (18O, 2H, 13C CMTD, 3H et 14C CMTD) permettant de déterminer l'origine de la salinité de l'aquifère.
Ce travail a mis en évidence le rôle de la partie libre de l'aquifère (aquifère de Crau) dans l'alimentation de l'aquifère captif. La forte augmentation de la salinité de l'aquifère captif depuis 1969 est ainsi principalement reliée à des baisses de charge naturelles ou anthropiques de l'aquifère de Crau. L'aquifère captif est soumis à des transferts de pression rapide depuis la mer mais également le Rhône qui s'accompagnent de transferts de masse très lents. En s'appuyant sur les rapports ioniques et isotopiques, ce travail a permis de démontrer que les fortes salinités de l'aquifère captif s'expliquent par un mélange eau douce/eau de mer fortement modifié par des interactions géochimiques : échanges de bases, processus de dégradation de la matière organique sédimentaire (sulfato-réduction, méthanogénèse), phénomènes de précipitations. Le temps moyen de séjour des eaux, supérieur à une cinquantaine d'année, témoigne de l'influence d'une intrusion marine ancienne en relation avec la dernière transgression marine (Holocène supérieur).

Full textThis study deals with the salinization of confined coastal aquifers in relation with sea level variations (past, future) and human pressures. The deep confined aquifer of Camargue has been studied in the framework of the ORE RESYST. This aquifer shows high salinities reaching that of the Mediterranean Sea near the shoreline. Two approaches have been jointly carried out: (i) an hydrodynamic study in steady and transient flow to understand the hydrogeological behaviour of the aquifer (flows, boundary conditions, hydrodynamic properties) and (ii) a monitoring of hydrochemical and isotopic natural tracers (18O, 2H, 13CCMTD, 3H and 14CCMTD) to determine the origin of the salinity of the aquifer. This work highlights the influence of the unconfined part of the aquifer (Crau aquifer) on the recharge of the confined aquifer. Thus, the high increase of salinity in the aquifer since 1969 is mainly due to natural or anthropogenic head depletion within the Crau aquifer. The confined aquifer shows rapid pressure transfers both from the Sea and the Rhone River whereas mass transfers are very low. Ionic and isotopic ratios highlight that strong salinities of the aquifer are due to a freshwater/seawater mixing, which is highly modified by geochemical interactions: cationic exchange, sedimentary organic matter degradation (sulphate reduction, methanogenesis), precipitation phenomena. The mean residence time of water is higher than fifty years and reflects the influence of a former marine intrusion related to the last marine transgression (upper Holocene)

Full textSubterranean waters of the complex volcano-sedimentary aquifer system, exploited for drinking water supply of the Djibouti capital, undergo a degradation of their quality faced with high population growth, rural exodus, desertification which is accentuated in a context to severe arid climate. This degradation expresses itself by the salinization and the contamination of waters in direct relation with the overexploitation. The hydrogeochemical data were analyzed by using a combination of classic and statistical geochemical methods to estimate the quality in order to recognize the geochemical processes governing the chemistry of subterranean waters. The study indicated a variety of origins and processes of waters salinization. Our study has demonstrated that the anomaly of strong salinity is certainly due to the phenomenon of marine intrusion. The mixture of the groundwater sheet with some sea water is justified by the strong contents in chlorides. However, salinity is acquired by the contribution of another source of salt water resulting from the remobilization of old salt water, probably trapped in scorias. This second source of chlorinated water, is different from some current sea water by its cationic procession, and would correspond to sea water modified by the interaction with the basalt. Our study allowed highlighting that the reactions of inverse cationic exchange bounded to the marine intrusion and the geochemical dissolution processes are the geochemical characteristics of waters contaminated by marine waters. The study of the chemical water quality of various aquifers shows excessive contents in major elements exceeding widely the authorized thresholds. The contents in trace elements (Se, As) show an important contamination of groundwater of the coastal plain. The increase of the toxic elements is probably due to the influence of the volcanic formations and is stressed by the salt intrusion, related to an intensive exploitation

Full textThe region of Annaba, situated in the North East of Algeria, contains in its underground water resources that represent a significant enough interest to feed people, water for agriculture and industry. This site is currently undergoing a gradual anthropogenic pressure becomes worrisome. Indeed, the continuous operation of the water has caused deterioration of water quality and negatively influenced the hydrodynamic equilibrium of the aquifer. It has also ensured the emergence of salt wedges even threatening in the short term and exploitation of the water and the proper functioning of wetlands.Based on the analytical results obtained for series of samples of more or less regular intervals, performed on the main measurement networks, we tried to identify key factors influencing the evolution of the physico-chemical water and delineate the advancing salt wedge. In this research, simulation models have proved to be very powerful tools to understand the hydrodynamic functioning of aquifers in the region of Annaba, situated north east of Algeria, taking into account the heterogeneity of environments. They have also highlighted a vulnerability of aquifers in coastal areas where there is inflow of the sea and stream chloride concentration large enough. The negative impacts on groundwater and ecosystems can become catastrophic if nothing is done to curb the problem.Models based on artificial neural networks have emerged as a powerful way to develop predictive relations between the different indicators of the management of water resources in the region. In this context of strong demand for water, only an integrated approach offers the possibility to manage these resources while respecting the natural environment, citizens' interests and those of economic actors. The research meets this need for integration, since the location and evaluation of groundwater resources, to protect their quality, but while evaluating the potential adverse effects. In this research, a new model of integrated management of water has been developed based on the relation of cause and effect addressing the entire cycle of water. Hydrological variables were developed and classified into five categories which are socio-economic constraints of pollution, water quality, impact of human activity and management of urban space and agriculture. The relevant variables were characterized using artificial neural networks, risk assessment on human health and the expert opinion. It has been demonstrated that a combination of practical measures necessary to ensure the sustainable management of water
