Define permeability

Short answer

Permeability is the ability of a rock or soil to transmit fluid through interconnected voids and fractures. It is quantified by the coefficient of permeability k (or hydraulic conductivity K, in m/s). Coarse materials (gravel, sand) are highly permeable; clays and intact granite are impermeable.

Define permeability.

Permeability is the property of a rock or soil by which it allows fluid (water) to pass through its interconnected pores, fractures and voids. Its measure is the coefficient of permeability kk (or hydraulic conductivity KK, in m/s). Gravel and clean sand are highly permeable; clay and unfractured granite are practically impermeable.
