“…Such models can also be used to simulate the fluctuations of the seawater-freshwater interface and transition zone due to groundwater pumping, groundwater evaporation, salt dissolution in coastal Sabkhas, climatic change, etc. (Sherif and Singh 1996;, Sherif and Kacimov 2005. Werner et al (2011) presented a critical evaluation of coastal aquifer management paradigms using published coastal aquifer case studies combined with a simple evaluation of the Uley South coastal aquifer, South Australia.…”

Groundwater pumping from Kalbha and Fujairah coastal aquifer of the United Arab Emirates (UAE) has increased significantly during the last two decades to meet the agriculture water demands. Due to the lack of natural replenishment from rainfall and the excessive pumping, groundwater levels have declined significantly causing an intrusion of seawater in the coastal aquifer of Wadi Ham. As a result, many pumping wells in the coastal zone have been terminated and a number of farms have been abandoned. In this paper, MODFLOW was used to simulate the groundwater flow and assess the seawater intrusion in the coastal aquifer of Wadi Ham. The model was calibrated against a five-year dataset of historical groundwater levels and validated against another eleven-year dataset. The effects of pumping on groundwater levels and seawater intrusion were investigated. Results showed that reducing the pumping from Khalbha well field will help to reduce the seawater intrusion into the southeastern part of the aquifer. Under the current groundwater pumping rates, the seawater will continue to migrate inland.

“…The Ghyben-Herzberg relation can be used to determine the shape and position of the sharp interface under static equilibrium conditions (Sherif and Singh, 1996). For example, using 1.025 g/cm3 as an average density of seawater, we find that the slope of the sharp interface is 40 times greater than that of the water table.…”

“…Saltwater is not considered a health risk per se, but its presence in soils or underground waters used for industrial, agricultural, or domestic purposes can have grave economic consequences. In coastal aquifers, prolonged overpumping of groundwater can lead to an encroachment of the interface between seawater and freshwater, through intrusion and/or upconing (Sherif and Singh, 1996;Bear et al, 1999).…”

“…Overexploitation of groundwater to meet the domestic and irrigation demands of increasing population is among the most important of these factors (Sherif and Singh, 1996;Werner et al, 2013). Some of the possible options to control seawater intrusion (SWI) and move towards sustainable management of coastal aquifers include the use of different arrangements of physical and hydraulic barriers (e.g.…”

This paper presents the results obtained from the application of aquifer storage and recovery (ASR) technique to control seawater intrusion (SWI) in coastal aquifers. The study is based on the numerical modelling experiments performed using the SUTRA (Saturated-Unsaturated TRAnsport) finite-element code on the Wadi Ham aquifer in the UAE. A three-dimensional numerical model of this aquifer is developed and calibrated based on the available hydrogeological data in real scale. A significant amount of SWI has been calculated for the year 2015 due to the high rates of pumping from the available local well fields. To study the future responses of the aquifer to different control actions, the transient responses of SWI are simulated over a 10-year planning horizon. The proposed management measure (ASR) is implemented in repeated cycles of artificial recharge, storage and recovery using an additional set of wells defined in the model. The results show that ASR is a reliable method in controlling SWI in coastal aquifer systems besides its conventional role in subsurface water banking.
