Porous media in geologic systems are usually inhomogeneous with respect to porosity and permeability. In addition, these parameters may evolve with time because of the chemical interaction between solids and pore fluid.We will illustrate how fluxes evolve in strongly inhomogeneous media and how different flow patterns and diagenetic changes depend on the porosity and permeability distribution.Finally we attempt to characterize anisotropic media by simple scaling rules and power laws as well as to predict the average effective transport coefficients. It is shown that the anisotropic media can be transformed into equivalent isotropic media with respect to the conductivity tensor.
