Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.
