The diffusion equation with variable parameters along the flow can be solved when the diffused quantity is confined to a narrow band. Solutions are obtained for diffusion from a line source and a point source in nonuniform flows. The dispersion of a contaminant in nonuniform flows through porous media is studied. It is found that the dispersion across the streamlines can be estimated by using the solutions of diffusion from a line source and a point source in a uniform flow.
