Fig. 12. Comparison between the vertical radar profiling (VRP)-derived moisture content profile at Borehole BB (thick line and confidence band with thin lines), the corresponding best result from Monte Carlo Richards' equation simulations (thick dashed line), and a deterministic Richards' equation simulation based on the data available without VRP information (thick dot-dashed line). The deterministic simulation uses lithological boundaries derived from drilling logs, and the following hydraulic conductivity estimates: K1 = 10 cm d1, K2 = 50 cm d1, and K3 = 340 cm d1 (value derived from in situ pumping test).
