<prompt> Andika mwendelezo wa aya hii - The 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 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. Uundaji wa kina wa mfano wa MARUN unapatikana katika Boufadel et al. 1998 na Boufadel et al. 1999. Mfano huo ulitumiwa kuchunguza mtiririko wa uvujaji katika mitaro na mabwawa Boufadel et al. 1999, Naba et al. 2002, uhamiaji wa brine baada ya uvukizaji Boufadel et al. 1999 na Geng na MC. 2015, utupaji wa maji ya chini ya maji Li et al. 2008, na hydrodynamics ya pwani kuelezea kudumu kwa baadhi ya mafuta ya Exxon Valdez  <response>: katika fukwe Alaska Li na Boufadel 2010.
