For the two-dimensional advection-diffusion equation of concentration distribution the analytical solution in which speeds of the advection are functions of spatial coordinates is found. The initial concentration distribution has been taken as the rectangular column. The numerical calculations were carried out for a few difference schemes and these calculations illustrate the basic properties of difference schemes well.
