Soil Anisotropy: Mechanisms and Hydrologic Consequences

Introduction Anisotropy, which is the opposite of “isotropy,” is a term used to denote preferential flow direction in soils and other geologic materials. If soil consisted of perfectly spherical grains, flow rates would be isotropic – the same in all directions, other factors being equal. Soil doesn’t consist of perfectly spherical grains, however. It’s commonly understood that flow of air and water through soils is greatly influenced by grain size, …
