Table 1 Physical properties and multi-modal van Genutchen parameters41 of simulated units/features. Results for in situ water content, thermogravimeteric analysis, and gas and mercury porosimetry on P-Tunnel grab/core samples are in parentheses11. Average of saturation and density values from other VNT units (0.65 and 2260, respectively) are used for VNT1, 6–10.
