The method of spatial averaging is apphed to derive a macroscopic form of Fick's law for unsteady diffusion through a rigid porous medium The validity of this form is found to be restricted by the requirements that diffusion is quasi-steady on a pore scale and that interphase mass transfer rates dep
## Abstract Porewater fluxes into or out of the sediments in aquatic systems are frequently estimated using Fick's First Law. This assumes that diffusive processes control the transport of nutrients. As a corollary, advection, bioturbation and chemical processes are assumed not to be significant. T
