> Geologic unit defined by genesis. The genesis is manifested by material properties, but the material is not the defining property. The geotechnical unit **IS** defined by its material properties.

Simple data requirements: (the following may all be used to create a model they are not exclusive to one particular model) The properties of the layers may or may not...
