We solve a System of coupled parabolic équation and nonlinear convection-diffusion équation. The MFE method is employed for the parabolic équation. A Godunov-type FV method is applied for the convective term and a conforming FE method with piecewise linear éléments is used for the dispersion term. The results of convergence as well as L°° and BV estimâtes are shown. Numerical simulations are given for a 2D problem related to nuclear waste repository.
