Figure 13.
The image features two graphs displaying sample average saturation S w over time, labelled as figures a and b. Both graphs have time on the horizontal axis marked in hours with a logarithmic scale ranging from 10 to 100000. The vertical axis indicates sample average saturation ranging from 0.70 to 1.0. The left graph labelled a features a red line for deterministic analysis and a shaded grey area representing stochastic analysis. The right graph labelled b follows a similar format but focuses on a narrower range of data within the same graphing context. Both graphs illustrate trends over time for different analytical methods.Time evolution of sample average saturation degree under condition HP2D for (a) 20 mm sample and (b) 40 mm sample. Each plot shows the deterministic result (red line) and results of 200 heterogeneous realisations (grey line)
