I need some functions of volumetric water content vs matric suction, and unsaturated permeability vs matric suction, of representative soils used in earth dam construction. Will it be possible to obtain them from the granulometric curve of the soil?
Yoermes, this is possible. Please review one of the works that I attach below. One must exercise caution while applying these pedotransfer functions (PTF); they may be applicable only to geomaterials of certain range of granulometry and other properties. Your job will be much easier if you end up finding a universal PTF for this purpose, or else you could choose different PTFs for different kind of soils in the earth dam.

Dear sir Partha Narayan Mishra, I appreciate your contribution. I immediately start studying that job. Regards!
Hello, try to open the link that is one of six video lessons by Prof. Fredlund.
The topic of unsaturated soils is wide and the assessment of properties is not immediate.

Of course you can also follow the others videolessons.

Thank, dear Claudio Oggeri! I will study them, as soon as the pandemic allows me to return to my office at the university, with full internet access.
Best regards.
