Abstract

Three-dimensional simulation of intrusion of salted water in an aquifer J.M. Crolet," F. Jacob,*, P. Lesaint," J. Mania* " Laboratoire de Calcul Scientifique, * Laboratoire de Geologic Structurale et Appliquee, Universite de Franche-Comte, 25030 Besangon, France ABSTRACT One of the lastest development for saltwater intrusion into freshwater was the model SUTRA. Below, a three dimensional model using the finite element method is presented. Salt water intrusion into coastal aquifer can be simulated in a confined or unconfined aquifer, with a formulation different for taking into account recharge, flux, pumping ... INTRODUCTION In an aquifer neighbour on sea, management of freshwater is usually a problem, and requires special attention to limit saltwater intrusion into aquifer. The extent of intrusion depends particularly on physical properties of the aquifer like conductivity, dispersivity, porosity, . . . and some
