column. In this comment, the hypothesis of identical profiles for all cases suggested by Poulovassilis et al. [1991] is tested against both analytical and numerical solutions, and their theoretical arguments in support of the hypothesis are examined. If the hypothesis were exact, it would hold for all cases both idealized and actual. We examine the hypothesis for four separate cases, three idealized cases for which analytical solutions are available and one of the actual soils for which the authors present a numerical solution. The hypothesis of exact profile matching is seen to fail in both the idealized cases and the actual soil since the matching of the surface fluxes at ponding gives rise to a difference in volume of cumulative infiltration. If the alternative approach of
