For water, this property is called hydraulic conductivity, and it is important for projects that depend on properties of soil and strata, such as earthen dams, retention ponds, dewatering systems, hydraulic structures, wells, landfills, and many other engineered facilities that rely on hydraulic conductivity for their proper function. Hydraulic conductivity of soils can vary by many orders of magnitude, from 1x10-2 cm/sec for highly permeable sands to 1x10-7 cm/sec for practically impermeable clays
