Based upon the Pearson Type VIII distribution function,
a general retention function which relates the saturation to
the capillary pressure in disturbed soils has been discovered.
This simple and yet complete function has been
shown to describe precisely the imbibition as well as the
drainage branch of the retention curve....
The work reported herein constitutes a final report for a project funded by the U.S. Department of Interior, Office of Water Resources and Technology, Grant No. 14-31-0001-4218.
