unsaturated hydraulic conductivity
The proportionality constant between the volumetric flux of water and the hydraulic gradient in a porous medium for cases of water content less than saturation.
Often expressed as a function of soil-water pressure head and/or water content, it includes the effects of the water-filled pore structure and the viscosity and density of the water.
