In soil machines Permeability is one of the important Engineering properties, as it governs rate of settlement of saturatedcompressible soil layer and rate of flow of equifer. Permeability is that property of soil which permits flow of water through its interconnecting voids. The instrument to measure permeability is called permeameter.
