Abstract

Abstract

Additional information has been obtained on the use of the radial-flow cell for measuring capillary conductivity and soil-water diffusivity. The equations used for describing unsaturated flow and the assumptions made in applying the equations to the transient outflow that occurs from the radial cell were described in a previous paper along with procedures for handling samples. Experience with both the linear-outflow method and the radial-outflow method indicates that the mathematical expressions developed to date do not accurately describe the transient outflow process. The reasons for the discrepancies are not fully understood.
