   • 2020, David J. Burdige, Geochemistry of Marine Sediments, page 304:

     Diffusive models assume that bioirrigation can be quantified by an enhanced, apparent diffusion coefficient within a defined (irrigated) sediment layer, while advective models use an apparent pore-water advection velocity to account for bioirrigation.
