Poroelastic wave propagation and physics-based soil characterization

The shallow subsoil is generally more porous than the deeper, compacted earth formations.  It has been found recently that the poroelastic wave propagation in the shallow subsoil layers can be practically utilized to obtain reliable, in-situ values of properties like hydraulic conductivity and porosity of the shallow soil layers. This has opened up a new direction of research in this field.
