“…Many challenges can hinder MAR implementation and maintenance and, hence, lead to failure. This section discusses several MAR failures that occurred in 10 MENA countries: Palestine (Adbul-Hamid, 2008;Ajjur & Mogheir, 2020b;Al-Khatib et al, 2019;Anabtawi, 2018), Yemen (Al-Qubatee, 2009), Jordan (Salameh et al, 2019;Xanke et al, 2017), Egypt (Dillon et al, 2018;Ghodeif et al, 2016), Iraq (Stevanović, 2015), Israel (Guttman et al, 2017;Idelovitch & Michail, 1985), Lebanon (Daher et al, 2011), Syria and the UAE (Dawoud, 2008), and Tunisia (Comte & Bachtouli, 2019). MAR challenges in the MENA region can be categorized into three primary concerns: technical issues, health-risk issues and socioeconomic aspects.…”

“…ESCWA and BGR, 2013). Heterogeneity in karst aquifer characteristics causes significant clogging and influence dispersion, and, hence, reduces the recovery rate (Daher et al, 2011;Van Ginkel et al, 2009). Our analysis shows failures in most MAR systems in karst aquifers.…”

“…All these attempts failed due to low rates of recharge and uptake (Dawoud, 2008). Another study from Lebanon concluded the non-feasibility of MAR, via infiltration ponds or injection wells, to the main Damour aquifer (Daher et al, 2011). Further, an aquifer storage and recovery project was implemented in the 2000s in the Hadith karst aquifer in Lebanon.…”

“…The source water comes from the Beirut River. Daher et al (2011) reported the non-feasibility of such an injection in the area due to technical and economic factors. Also, Idelovitch and Michail (1985) documented low infiltration rates in spreading basins in the Dan project in Israel due to high heterogenicity in geological layers.…”

The study critically reviews the application, management and challenges of managed aquifer recharge (MAR) in the Middle East and North Africa (MENA) region through a survey of 142 studies. The survey reveals the objectives and methods of MAR in the region. It also shows the technical and socioeconomic challenges that significantly cause MAR failure in MENA countries. The article concludes by presenting a framework to evaluate MAR feasibility and it provides recommendations and guidance for future studies and MAR designs in the MENA region, which is facing the impact of climate change.

“…Indeed, the main agent of the dissolution of carbonates is the biogenic CO 2 , supplied by the organic matter mineralization and stored in the soil, a few meters above the epikarst [30]. However, the CO 2 -H 2 O-Ca (1−x) Mg (x) CO 3 system is sensitive to environmental changes due to karstic characteristics such as high transmissivity (lower residence time), high dissolution kinetics, and low filtering role of the infiltration zone [31].…”

The long-term trends and seasonal patterns of stream water chemical composition in a small remote forested karst catchment, were investigated from 1978 to 2018. Calcium, magnesium, and bicarbonates, the dominant ions, increased over the period together with temperature, while sulfates decreased. Carbonate and sulfate mineral dissolution was the main source of these elements. These trends and the seasonal opposite patterns of discharge vs. temperature, calcite saturation index vs. pCO2 and bicarbonate vs. sulfates, suggested the influence of discharge, of reduced long-range atmospheric pollution, and of increasing air temperature on biological activity and carbonate dissolution. Furthermore, the hydrological regime controlled the seasonal stream water chemical composition and fluxes by: (i) a dilution during the high discharge period, (ii) a change in the contribution rate of the waters draining different lithological areas in the catchment, e.g., the increased sulfates to bicarbonates ratio during summer low flows, with a maximum alkalinity decrease of 24%, and (iii) a “piston” and a “flushing” effects of dissolved elements stored in soils and epikarst with the first autumn heavy rains. Long-term stream water hydrochemical surveys of karst system have proved to be powerful indicators of biogeochemical processes, water sources and pathways under variable natural and anthropogenic environmental pressure conditions.

Modelling regional effects of artificial groundwater recharge in a multilayer aquifer characterized by perched water tables

This paper presents an approach to estimate the effects of a managed recharge experiment in a multilayer aquifer characterized by the presence of perched water tables in the Medina del Campo groundwater body, Douro basin, central Spain. A numerical model was developed to evaluate the effect of artificial recharge on the shallow sector of a regional‐scale aquifer and on formerly active wetlands. The model was developed in the Visual MODFLOW Pro v.2011.1 environment in order to represent and analyse the regional impact of this artificial recharge event. Results suggest that the assumption of a single perched system may prove useful in regional contexts where data is limited. From a study site perspective, managed recharge is observed to increase shallow storage along the riverbanks, which is considered valuable for environmental purposes. However, downstream wetlands are unlikely to experience a significant recovery. Furthermore, only a small percentage of artificial recharge is expected to reach the deep regional aquifer. This method can be exported to settings characterized by the presence of perched aquifers and associated groundwater dependent ecosystems.
