The conceptual model of a random function, as a suitable representation of the natural variability in soil deposits is introduced and explained. After the necessary numerical procedures are described, the mathematical concepts of the theory of random functions are applied to a collection of soil records that range from soft clays to gravelly sand deposits. A correlation approach provides a simple and precise description of soil heterogeneity in terms of the autocovariance function, power spectra function, and underlying probability distribution. Typical values of the defined parameters likely to be encountered in soils are given, and general trends and simplified models are discussed. Refs.
