Figure 11.
The scatter plot shows diffusion coefficient plotted against porosity for boom clay and synthetic samples. Data points include S M 1, S M 2, S M 3, S M 4, S M 5, S M 6, and B C 2, B C 3, B C 4, and B C 5, with diffusion ranging from about 1.0 into 10 power minus 10 to about 6.5 into 10 power minus 10, and porosity from about 31 to 41. A linear trend line increases from lower diffusion at lower porosity to higher diffusion at higher porosity, with equation y 3 into 10 power minus 9 x minus 9 into 10 power minus 10, and R squared 0.4135.Estimated porosity versus diffusion coefficient from Tables 2 and 7. Solid red circles show BC samples cut perpendicular to bedding while light red circles are for BC samples cut parallel to bedding
