<prompt> Pedzisa mutsara unotevera: Marine Unsaturated Model MARUN model is 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. Kuumbwa kwakadzama kwemuenzaniso weMARUN kunowanikwa mu Boufadel et al. 1998 uye Boufadel et al. 1999. Muenzaniso uyu wakashandiswa kuongorora kuyerera kwemvura inoyerera mumakomba nemadhamu Boufadel et al. 1999, Naba et al. 2002 , kutama kwemvura yemunyu zvichitevera kupera kwemvura Boufadel et al. 1999 uye Geng and M.C. 2015, kuburitswa kwemvura yepasi pevhu Li et al. 2008, uye hydrodynamics yemahombekombe kutsanangura kuramba kwevamwe ve  <response>: Exxon Valdez mafuta pamhenderekedzo dzeAlaska Li naBoufadel 2010.
