Abstract

It is now generally accepted that the dispersion length, as defined in the classical advection-dispersion equation, is scale dependent. This report collates and reviews some of the models and techniques that have led to present understanding of solute transport in spatially stochastic media, including the early work of Taylor on diffusion, and the work of Saffman on capillaries, through to the more recent contributions of Dagan and Gelhar which regard the advective-dispersion equation as having stochastic parameters. The reports highlight the physical arguments and in places derive some of the more obscure results.
