Hydraulic conductivity means the quantity of water that will flow through a unit cross-sectional area of a porous material per unit of time under a hydraulic gradient of 1.0;
Hydraulic conductivity means the rate of water movement through the soil measured in meters per day (m/d) as determined by the following methods. For a saturated soil, the Bouwer-Rice method or its equivalent shall be used. For unsaturated soil, use a Guelph permeameter or an equivalent in situ constant-head permeameter in a boring finished above the water table. If an in situ method cannot be used for unsaturated soil because of depth, or if the soil is homogeneous and lacks flow-conducting channels, fractures, cavities, etc., laboratory measurement of hydraulic conductivity is acceptable.
Hydraulic conductivity means a specific mathematical coefficient (quantitative) that relates the rate of water movement to the hydraulic gradient. A term of Darcy’s law Q = KAi where K represents hydraulic conductivity and is the current standard for measuring a soils ability to transmit water.

More Definitions of Hydraulic conductivity
Hydraulic conductivity means the rate at which water can move through a permeable medium (i.e., the coefficient of permeability).
Hydraulic conductivity means the volume of water at the existing kinematic viscosity that will move in a porous medium in unit time under a unit hydraulic gradient through a unit area measured at right angles to the direction of flow.
Hydraulic conductivity means a measure of the capacity of a porous medium (rock or soil) to transmit water. It is expressed as the volume of water that will flow through a unit length of a unit cross-sectional area of the porous medium in a unit time with a unit head loss.
Hydraulic conductivity means the rate of flow in gallons per day (gpd) through a cross section of one square foot (ft2) under a unit hydraulic gradient (gpd/ft2).
Hydraulic conductivity means the rate of water movement through the soil measured in meters per day (m/d) as determined by the following methods. For a saturated soil, the Bouwer-Rice method or its equivalent shall be used. For unsaturated soil, use a Guelph permeameter or an equivalent in situ

Samples shall be clearly marked, preserved and transported to the laboratory. The laboratory shall measure hydraulic conductivity using a constant-head permeameter in accordance with ASTM Standard D2434 or a falling-head permeameter in accordance with accepted methodology.
