Hydraulic conductivity: The rate at which water can move through a permeable medium.
Hydraulic gradient: In general, the direction of groundwater flow due to changes in the depth of the water table.
Hydraulic Conductivity (K): A coefficient of proportionality describing the rate at which water can move through a permeable medium. It is a function of the porous medium and the fluid.
Hydraulic Conductivity: The rate at which water can move through a permeable medium, i.e., the coefficient of permeability.
Hydraulic Gradient: In general, the direction of groundwater flow due to changes in the depth of the water table.
HYDRAULIC CONDUCTIVITY
Refers to the capability of subsurface materials (sand, rock etc.) to allow a fluid (usually water) to flow through it.

Hydraulic Conductivity (K)
A measure of the ability of an aquifer to transmit a fluid; ...
Hydraulic Conductivity
The rate at which water can move through a permeable medium. Aquifers with high hydraulic conductivity yield and transmit more water than similar aquifers with low hydraulic conductivity.
Hydraulic Gradient ...
hydraulic conductivity (conductivité hydraulique) The proportionality factor in Darcy's law as applied to the viscous flow of water in soil, that is, the flux of water per unit gradient of the hydraulic potential.
hydraulic conductivity A measure of the rate at which water can move through a permeable medium if the hydraulic gradient of the ground-water flow system is unity (45 degrees).
bail piezometer test A single well test to determine the in-situ hydraulic conductivity of an aquifer by the instantaneous removal of a known quantity of water from a well, and the subsequent measurement of the recovery as a function of time.
Confining layer: Geologic material with little or no permeability or hydraulic conductivity. Water does not pass through this layer or the rate of movement is extremely slow.
permeability : A qualitative description of the relative ease with which rock, soil, or sediment will transmit a fluid (liquid or gas). Often used as a synonym for hydraulic conductivity or coefficient of permeability.
