directional hydraulic conductivity

Combined property of an anisotropic porous medium and the flow through it. When a given direction coincides with that of the specific discharge, the directional hydraulic conductivity in that direction is the ratio of the specific discharge to the projection of the hydraulic gradient in that direction when the given direction coincides with that of the hydraulic gradient, it is the ratio of the projection of the specific discharge in that direction to the hydraulic gradient.
