MEASURED AND APPROXIMATE FLUX-CONCENTRATION RELATIONS FOR ABSORPTION OF WATER BY SOIL.

Abstract

The flux-concentration relation of J. R. Philip is calculated using moisture profiles measured during absorption of water by a fine sand when water was supplied at both constant hydraulic potential and constant The general The general behavior of the measured flux-concentration relations was found to be consistent with those of the model soils calculated by Philip. Within the accuracy of the measurements, no significant time-dependence of the relation was found for the constant flux boundary condition over a large time span. Show more
