A note on the drawdown, diffusive behavior of fractured rocks

Abstract

Transients in fractured media are described using a model in which permeability depends on space and time. The motivation for the differential equation used here draws on recent results for diffusion on fractals in the asymptotic regime. The solution proposed is consistent with the scaling arguments for diffusion on fractal structures. Known results for transients in fractured rocks may be extracted from the solution given here.
