Abstract

. A modelling procedure of the two-dimensional advection-dispersion equa- tion based on a finite volume method for the spatial discretization is pre- sented in this paper. Control volumes are made up over a standard triangu- lation, which give the grid nodes where we obtain the numerical solutions. A first order accurate interpolation is used over each triangle that contains the control volume. Some idealized initial value problems are studied show- ing the practical advantages and disadvantages of the method in comparison with analytical solutions. 1 Introduction. The advection-dispersion equation is used extens
