Permeability refers to a soil’s ability to allow water to flow through its interconnected voids. This property is critical in engineering because it influences how quickly saturated, compressible soil layers settle and how much water an aquifer can supply. Permeability is considered in various applications, such as pumping groundwater, spacing well points for dewatering excavation sites, designing reservoirs and dams, and selecting soils for different parts of embankments in dams and reservoirs…
