Abstract: Fractal approach is used to derive a power law relation between
effective diffusion coefficient of solute in porous media and the geometry
parameter characterizing the media. The results are consistent with the
empirical equations analogous to Archie'slaw and are expected to be applied to
prediction of effective diffusion coefficient.
