Abstract

The simple methods of LIBARDI et al. (1980) and SISSON et al. (1980) for K(theta) estimation, although developed on completely different theoretical basis, are rigorously identical for the exponential hydraulic conductivity model. The unit gradient approximation used in these methods seems valid for practical purposes but is theoretically in valid.
