What is permeability?

Permeability refers to the ability of rock or soil to allow water to flow through it. This property is crucial in various environmental and geological processes, including aquifer recharge, soil drainage, and the movement of contaminants in the subsurface. Soils and rocks with high permeability, such as sandy soils, allow water to pass through quickly, while those with low permeability, like clay, restrict water movement.

Understanding permeability is essential for effective water management and environmental studies, as it influences the behavior of water in terrestrial ecosystems, groundwater flow, and even construction projects. This ability also affects plant growth, as permeable soils can retain moisture and provide adequate drainage for roots.
