Chapter 7 Permeability and Seepage

geotechnical engineering k is commonly expressed in cm/s (although m/s is the preferred metric unit), and other possible units include m/s, m/day, and mm/hour. In mining engineering, mm/hour is the preferred unit for permeability of mine fills and bricks. In coarse grained soils, the effective grain size D10 has good correlation with permeability.
