Description:
The report describes a new correlation or predicting gas permeabilities of undisturbed or recompacted soils from their average grain diameter (d), moisture saturation factor (m), and porosity (p). he correlation exhibits a geometric standard deviation (GSD) of only 1.27 between measured and predicted permeabilities for the Florida soils, with no residual bias, and a GSD of 1.44 for the combined Florida and Utah data sets with a 3% negative bias. esults of a literature review of previous relations between soil properties and gas or water permeabilities show that previous exponents for particle size dependence have ranged from 1.11 to 2.05, consistent with the present value of 1.33.
