Darcy’s Law : Laminar flow: Flow follows a well-defined path and doesn’t cross the path of other particles (Re ≤ 2000)

Soil Permeability - Darcy

If the soil is not fully saturated, it contains air pockets. The permeability is reduced due to the presence of air which causes a blockage to the passage of water. Consequently, the permeability of a partially saturated soil is considerably smaller than that of fully saturated soil. In fact, Darcy's Law is not strictly applicable to such soils.
