Abstract

Groundwater contaminations by salt water are frequently observed especially in coastal zones. Moreover, upconing phenomena induced by important pumping is one of the major factor stressing and aggravating the process. After a short synthesis of the coupled equations describing the transport and density dependent flow, a finite element program able to simulate accurately this kind of problems is proposed: the SUFT program (Saturated Unsaturated Flow and Transport model). In order to avoid numerical instabilities, two methods have been introduced in this code covering by this way all the practical cases: the convection dominated as well as the dispersion/diffusion dominated transport cases.
