Kozeny equation permeability

WebPlant roots can change the soil water retention curve (SWRC) and saturated permeability (k (sat)) of vegetated soils. However, there is no model that could capture both the effects of root growth and root decay on these soil hydraulic properties simultaneously. WebA well-known relationship between permeability and properties of pores was proposed by Kozeny and later modified by Carman. The resulting equation is largely known under …
