FIG. 7. Comparison of quasi-steady-state microgravity (µg) drainage and wetting water retention and steady-state 1-g porous media water retention for Profile, Turface, and a mixture of these obtained in the 1-cm cell. The solid lines are predicted 1-g retention curves (upper = drainage, lower = wetting). Dashed or dotted lines indicate the 95% confidence interval for the 1-g retention curves. Indicated water contents are shown as average sample values determined from pumping volumes. Matric potentials were measured at z = 0.5 cm.
