“…The volume of discharge is several times less than eastern recharge because of the flat coastal groundwater head and less conductive formation. Compared to the model developed by Eggleston et al (2020), the coastal discharge and evapotranspiration were increased due to the bigger size of model domain in this case. Additionally, the 2% to 5% of rainfall used as recharge was calculated by the method of groundwater fluctuation and it is higher than the percentage of rainfall used by [38].…”

“…As a result, the salinity (a concentration of total dissolved solids) of groundwater in the Sabkha region is reported up to 150 gL −1 which is more than three times higher than the salinity of seawater in the Persian Gulf (42 gL −1 ) and several times higher than the salinity of groundwater from the deeper aquifer (83 gL −1 ) (Stanford and Wood 2001). Moving to the inland: dune surface and piedmont region, the availability of groundwater under desirable quality is less than 2.97% [38].…”

“…The humidity varies between 25% in the eastern part and 90% in the coastal boundary. The annual pan evaporation ranges between 3400 mmyr −1 and 4400 mmyr −1 [36,37] and evapotranspiration is 62.05 mmyr −1 [38]. The elevation varies from 0 m above mean sea level (AMSL) at the coastal boundary to 1163 m AMSL at the Jabal Hafit Mountain located at the eastern sector.…”

“…From the literature, it is also reported that the salinity of groundwater from the surficial aquifer is higher than the salinity of groundwater from the deepest formation along the coast and waterlogged areas [48]. It is reported that the freshwater is already replaced by brackish water in several parts and continuation of groundwater pumping at the present rate will turn this regional aquifer completely brackish and saline in the near future [4,38].…”

“…Several soil tests and pumping tests were conducted as part of the GWRP project between the years 1988 and 1995 at more than a hundred locations [4]. The aquifer properties were extracted from the above report published by [4,38]. In a particular way, the hydraulic conductivity assigned in the top four layers ranges from 2.74 × 10 −8 md −1 to 266 md −1 .…”

In Abu Dhabi, one of the most arid regions in the world, in recent decades, desalinated water has been identified as a prime solution in solving the water demand issues. In this study, a three-dimensional coupled density-dependent flow and solute transport model was set up in order to study the effect of the artificial recharge using desalinated water and the influence of nonconventional water with a salt concentration in the range 0.1–2 g/L The results confirm that this region demands the adoption of a more rational use of irrigation water or additional usage of desalinated water and recycled water together with optimizing groundwater pumping at locations that are vulnerable to further quality degradation and depletion. The long-term storage of desalinated freshwater with a maximum radial distance of 653 m in the dune surface is ensured with the formation of the transition zone, and change in the groundwater head up to 5 km. The maximum recovery obtained by immediate recovery is 70%. The study expresses the long-term feasibility of desalinated freshwater storage and the need for further management practices in quantifying the contribution of desalinated and recycled water for agriculture activities which might have improved groundwater quality and increased hydraulic head at some locations.

The United Arab Emirates (UAE) is dependent on desalinated water and shallow aquifers to satisfy its freshwater requirements. Despite the paramount importance of understanding the depth and spatial extent of these aquifers, comprehensive investigations into the properties of these aquifers, as well as the underlying subsurface structures and stratigraphy, have been conspicuously lacking. This study presents the findings of integrated geophysical and borehole investigations conducted in the Al Jaww Plain, southeastern Al Ain, UAE, focusing on the properties of groundwater aquifers, the Semail ophiolite contact, and subsurface structures and stratigraphy. Through the analysis of groundwater borehole data, three interconnected types of groundwater aquifers have been identified, and characterized by their hydrogeological properties. The near-surface Quaternary unconfined aquifer, with an average thickness of 25 m, represents a fresh groundwater aquifer. The second aquifer, with an average thickness of 110 m, is connected to the upper Quaternary freshwater aquifer and is interpreted as part of the surficial aquifer system. The third aquifer has an average thickness of 200 m. By employing electrical resistivity tomography, the depth of the water table and groundwater potential in the shallow unconfined Quaternary aquifer near Jabal Mundassa have been estimated, aligning with the properties observed in the unconfined Quaternary aquifer across the entire Al Jaww Plain as depicted in the groundwater borehole cross section. In addition, this study provides insights into subsurface structures and stratigraphic features, revealing the westward extension of the Hawasina thrust sheet within the plain. Gravity and magnetic data analyses in the southeastern region of the Al Jaww Plain delineate the extent of the Semail ophiolite. Notably, magnetic data reveals the presence of an NW–SE-oriented magnetic anomaly detached from the main ophiolite thrust, which corresponds to the interpretation of the Semail ophiolite contact with sedimentary carbonate rocks on the Bouguer gravity map.
