Desalinated water is one of the non-conventional
water resources where fresh water is produced before constructing a desalination plant. The
brine resulted from the desalination process is
usually injected into aquifer or discharged into
the sea. The practice of disposing the rejected
brine into the sea is common for plants located in
coastal areas. The aim of this research was to simulate the brine disposal fate within an aquifer. The Visual
MODFLOW numerical code was used to predict the salt concentration emigration over time in an
aquifer. The model was calibrated using laboratory experimental data. The model results revealed
that there is an acceptable agreement between the observed and simulated data.
