Hydraulic Conductivity

Hydraulic conductivity is a physical property which measures the ability of the material to transmit fluid through pore spaces and fractures in the presence of an applied hydraulic gradient. Darcy's Law defines the hydraulic conductivity as the ratio of the average velocity of a fluid through a cross-sectional area (Darcy's velocity) to the applied hydraulic gradient.[1]

Wikipedia Definition

Hydraulic conductivity, symbolically represented as K {\displaystyle K} , is a property of vascular plants, soils and rocks, that describes the ease with which a fluid (usually water) can move through pore spaces or fractures. It depends on the intrinsic permeability of the material, the degree of saturation, and on the density and viscosity of the fluid. Saturated hydraulic conductivity, Ksat, describes water movement through saturated media.By definition, hydraulic conductivity is the ratio of velocity to hydraulic gradient indicating permeability of porous media.
