Permeability

Permeability is the ability of a material to allow fluids, like water or air, to pass through it. Imagine a sponge: it has high permeability because water easily flows through it. Conversely, materials like clay have low permeability, meaning water doesn’t travel through them easily. This property is important in fields like geology, engineering, and environmental science, as it affects water drainage, the movement of groundwater, and the behavior of soils and rocks. Understanding permeability helps in designing infrastructure, managing water resources, and assessing environmental impacts.
