permeable media

Permeable media refers to materials or substances that allow fluids, such as water or air, to pass through them easily. Examples include sandy soil and gravel. The degree of permeability depends on how connected the tiny pores or spaces within the material are. These materials are important in fields like hydrogeology, environmental engineering, and construction because they influence how underground water moves, how pollutants spread, or how water can be extracted or managed. Understanding permeability helps in designing effective drainage systems, groundwater extraction, and pollution control, ensuring safe and efficient management of natural and built environments.
