The writer reviews some of the best known features of mechanical dispersion and the influence of molecular diffusion on breakthrough curves obtained for saturated and nonsaturated samples of porous medium. Miscible flow is also considered as flow of a non‐homogeneous fluid in a porous medium. Special concepts of head, as introduced by Lusczynski, are reviewed and modified in order to facilitate the determination of the velocity field in the zone of dispersion. The method described is applicable in principle to the migration of water in building materials exposed to sea water.
