Abstract

The permeabilities and dispersivities of geologic media are known to vary with the scale of observation. Particularly well documented is the consistent increase in apparent longitudinal dispersivity with the mean travel distance of a tracer. This has been previously interpreted to imply that the permeabilities of many geologic media scale, on the average, according to the power-law semivariogram γ(s) = c √ s where c is a constant and s is distance. The present paper cites evidence for such behavior over scales from 10 cm to 45 km based directly on permeability and transmissivity data. The paper then investigates theoretically the implications of such power-law behavior on the equivalent permeability of a block of rock having a characteristic length. -from Author
