THE THEORETICAL INTERPRETATION OF FIELD OBSERVATIONS OF SOIL SWELLING THROUGH A MATERIAL COORDINATE TRANSFORMATION

The nature of material coordinate transformations and their importance to the theoretical interpretation of time-dependent data taken on swelling soil-water-air systems is discussed. A material coordinate transformation that is based on a special case of a general relation derived by Raats and Klute, but that has not yet been applied to swelling soil, is proposed as a useful expression with which to describe one-dimensional soil water processes in the field. This transformation requires only the measurement of bulk density in time sequences from a set of one or more fixed points and, therefore, should be especially valuable when used in conjunction with dual energy gamma-ray measurements of soil profile properties. An illustrative application of the proposed transformation is made to interpret dual energy gamma-ray data on the swelling of Avondale clay loam.
