N2 - An experimental procedure is developed for the measurement of the hydraulic conductivity of unsaturated soil on wetting and drying processes taking into account the hysteresis phenomenon. The proposed method expedites the measurement of the hydraulic properties, minimizes experimental errors, and avoids ambiguity due to hysteresis. The dependence of the membrane conductance in a flow cell on the soil water content was also investigated. The membrane conductance decreases by several orders of magnitude as the soil dries, and increases following a wetting process. A power function seems to represent quite well the relationship between the membrane relative conductance and the soil relative hydraulic conductivity.
