Abstract

In the particular case of a stratified soil, the diffusivity tensor is defined by the two values of the diffusivity in the principal directions, one normal and one parallel to the soil layer. The new method makes use of a two-dimensional similarity solution first derived for an isotropic medium and extended to a stratified soil. It is then possible to obtain the diffusivity tensor of the stratified soil from one experiment only. As an illustration of the method, the diffusivity tensor of a mica layer is measured and the result is used to analyze infiltration from a finite trench.
