In their attempt to describe dispersion phenomena in mathematical form several authors arrived at the conclusion, that a porous medium possesses a coefficient of dispersion, which has the character of a tensor. This tensor is formulated in such a manner, that it represents the geometrical aspects of the porous medium responsible for the scatter of tracer particles, when carried by a fluid flowing through it. It is therefore a poperty of the porous medium alone, and can be considered to materialize the tortuosity of the particle trails caused by the random arrangement and the interconnectivity of the channels constituining the pore space.
