Marine Unsaturated Model ( MARUN model ) is a two-dimensional ( vertical slice ) finite element model capable of simulating the migration of water and solutes in saturated-unsaturated porous media while accounting for the impact of solute concentration on water density and viscosity , as saltwater is heaving and more viscous than freshwater . The detailed formulation of the MARUN model is found in ( Boufadel et al. 1998 ) and ( Boufadel et al. 1999 ) . The model was used to investigate seepage flow in trenches and dams ( Boufadel et al. 1999 , Naba et al. 2002 ) , the migration of brine following evaporation ( Boufadel et al. 1999 ) and ( Geng and M.C. 2015 ) , submarine groundwater discharge ( Li et al. 2008 ) , and beach hydrodynamics to explain the persistence of some of the Exxon Valdez oil in Alaska beaches ( Li and Boufadel 2010 )
