Figure 7.
The graph displays a three dimensional representation of effective permeability in square metres on the vertical axis against the degree of saturation in percentage on the horizontal axis. The effective permeability values range from 1 times 10 to the power of minus 22 to 1 times 10 to the power of minus 21. The graph shows a direct relationship as the degree of saturation increases from 0 to 100 percent. Key parameters are represented with symbols, including a yellow diamond for 1.6 grams per cubic centimetre, an orange diamond for 1.65 grams per cubic centimetre, and a red square for 1.8 grams per cubic centimetre. Annotations reference test data from Lloret et al, 2004, and indicate that porosity is inversely related to intrinsic permeability as it increases. An arrow points towards the relative permeability, emphasising the increasing trend along the horizontal axis.Degree of liquid saturation () – porosity () – effective permeability () path for FEBEX bentonite.
