Air entry-based characteristic length for estimation of permeability of variably compacted earth materials

, : Air entry-based characteristic length for estimation of permeability of variably compacted earth materials. Water Resources Research: 11, W11403

The permeability <i>k</i> of a porous medium is a geometrical pore space attribute required for quantifying fluid flows and transport processes for hydrological, civil, agriculture, and petroleum engineering applications. Permeability is often expressed as proportional to a characteristic length squared and inversely proportional to factors accounting for porosity, pore shape, and tortuosity effects.
