Abstract

Presents a solution to the two-layer problem that can be computed using inexpensive personal computers and spreadsheet software. Testing the solution over a range of thermal diffusivity values expected in common soils and rocks reveals that the solution is very sensitive to variations in the thermal diffusivity of the surface layer and to the depth of the interface with the lower layer. When the boundary to the lower layer is less than about 10 m deep, a soil temperature survey is expected to be sensitive to the diffusivity variations in the lower layer. Because variations in shallow thermal properties often can be significant, this two-layer method should be useful in areas with distinct shallow layering, (e.g., where there is a shallow water table or a thin soil layer). -from Authors
