Unsaturated Permeability

Unsaturated permeability refers to the ability of soil or rock to allow water to flow through it when it is not fully saturated with water. In simpler terms, it measures how easily water can move through materials that contain both air and water in their pores, like a sponge with some dry areas. This property is important in environmental studies, construction, and agriculture, as it affects how water drains, how plants access moisture, and how pollutants may spread in the ground. Understanding unsaturated permeability helps engineers and scientists manage water resources effectively.
