Differentiate between Hydraulic Conductivity and Intrinsic Permeability

What is the difference between hydraulic conductivity and intrinsic permeability?

Hydraulic Conductivity vs. Intrinsic Permeability

Hydraulic conductivity is the property of the soil that determines the rate of flow of water per unit area under unit hydraulic gradient. It measures how easily water can move through a soil.

Intrinsic permeability is a measure of the soil's ability to transmit water under laminar flow conditions. It measures the soil's ability to transmit water through its pores.

The difference lies in their focus: hydraulic conductivity measures the rate of flow of water, while intrinsic permeability focuses on the soil's ability to transmit water under specific flow conditions.

Both properties are important in determining the flow of water through soil and are often used together to understand soil properties better.
