A modification of the constant-head permeameter to measure saturated hydraulic conductivity of highly permeable media.

The saturated hydraulic conductivity ( ) is a key characteristic of porous media, describing the rate of water flow through saturated porous media. It is an indispensable parameter in a broad range of simulation models that quantify saturated and/or unsaturated water flow. The constant-head permeameter test is a common laboratory method to determine K on undisturbed soil samples collected from the field.
