Population growth and scarcity of coastal freshwater resources have increased the stresses on many coastal aquifers, leading to aquifer storage decline and seawater intrusion (SWI) [1, 2 and 3]. Controlling or predicting SWI under future climatic or anthropogenic scenarios requires mathematical tools. This research deals with the current quality condition of Asaluyeh coastal aquifer located at Boushehr Province, south of Iran. The amount of Persian Gulf SWI is simulated using dispersive approach. Gavbandi river recharge, adjacent groundwater inflows as boundary condition, rainfall recharge and all distributed wells are included at the simulations. In the literature, multiple methods have been proposed for controlling SWI including reduction of pumping rates, relocation of pumping wells, use of subsurface barriers, natural recharge, artificial recharge and abstraction of saline water [4, 5]. A new controlling method is developed at this study to control SWI effectively. This methodology ADR (Abstraction, Desalination and Recharge) includes abstraction of seawater, desalination of seawater using common methods such as reverse osmoses and recharge of a part or all of the excess desalinated water to the aquifer while the rest of the desalinated water can be used for domestic consumption (Fig. 1).
