FIG. 6. Measured and modeled matric potentials as a response to variable gravity in the 7-cm cell for porous ceramic aggregate Profile. Figures on the left side (b–e) show measured matric potentials for three observation heights at z = 1, 3, and 5 cm (Fig. 2) as a function of time for different water contents 
, where (a) depicts the gravitational acceleration and change in aircraft cabin pressure for plot (b). Figures on the right side compare measured (lines) and simulated (symbols) matric potentials in microgravity following hypergravity (g–j). In (f), measured normalized gravitational accelerations are depicted for measurements shown in (g).
