A mathematic model is presented which describes the salt water-fresh water motion with a sharp interface, assuming the validity of the Dupuit approximation. This model is used as a base to derive a numeric-model (finite difference method) which is unconditionally convergent and stable. A method for solving the equations is selected together with a convergence accelerating procedure. The treatment of the boundary conditions in the interface is discussed, and a general and automatic solution for that problem is presented. Several tests with analytic solutions have been performed with good results. 13 references.
