Abstract: Experiments are carried out to determine the coefficient, D, of lateral dispersion in flow through porous media, with values of R between 0.3 and 380. It Is found that, when R reaches a value of about 10, there is a change in the relationship between the coefficient D and the seepage velocity. The data indicate that the variation of the flow pattern with the Reynolds number is important in the study of dispersion, even when Darcy's law is applicable.
