The development of coastal regions is largely dependent on the groundwater system, which is the primary source of freshwater in these areas. Saltwater intrusion (SWI) into freshwater coastal aquifers is a widespread environmental concern that causes groundwater quality to deteriorate. This study investigates the impact of using artificial recharge through groundwater wells to control saltwater intrusion in unconfined coastal aquifers. The SEAWAT code is implemented to investigate the impact of injection of freshwater through groundwater wells to control saltwater intrusion in coastal aquifers. The semi-analytical of seawater wedge compared with the SEAWAT code solution for model verification. The artificial recharge tested for various depths of groundwater well, distances from the seaside, and artificial recharge rate. The points of artificial recharge located outside the saltwater intrusion wedge. The results confirmed that injection freshwater near to the toe of seawater intrusion achieved higher repulsion ratio. The maximum repulsion ration of seawater intrusion equal 18.2% achieved at point 7, which close to the sweater intrusion toe with injection ate equal 0.14 m3/sec. Injection freshwater at points 7, 11, and 15 achieved the highest repulsion ration for different values of injection rates. The minimum achieved repulsion ratio equals 5.8%, observed at point 1, which located far away from the point of toe. The findings of this research can be used to management of freshwater in groundwater systems in coastal aquifers.
