Abstract

In many environmentaly important cases of subsurface flow and transport, the density of the liquid phase depends on solute concentration. When density variations are large (> 5%), flow and transport are strongly coupled. Density variations in excess of 20% occur in salt dome and bedded-salt formation. To analyze such complex phenomena, a simulation code (VIDE POMM'S) has been developed. It is based on the mixed hybrid finite element method (MHFEM) which permits to compute waterflow and solute transport. The coupling between groundwater flow and solute transport is realised by equations of state. We assume that in the mixing zone the density varies linearly with the concentrat
