Etymology
From bio- + irrigation.
Meanings
-
(uncountable) Irrigation by a biological organization, sometimes as a result of bioturbation.
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.
