Permeability Testing in Unconsolidated Materials
by: Sebastien Fortin, E.I.T., M.Sc.
Numerous engineering and site characterization projects require the determination of the permeability (or hydraulic conductivity) of a soil. Indeed, the permeability of the substratum, be it natural ground or mine waste material (waste rock, tailings, leached rock) is a critical parameter for design and construction purposes as well as for numerical modeling applications. Various methods and approaches are available to the engineer or scientist in charge of determining this parameter. The most appropriate method depends on factors such as project objectives, material properties, site access, budget among others. This paper describes different permeability testing methods for unconsolidated materials with special emphasis on in-situ determination of permeability in the vadose zone.
