Abstract: Dimensionless equations for the hydraulic conductivity of crushed rock and river gravel have been developed on the basis of approximately 1250 permeameter tests. Experimental data of a number of researches were used in the correlations. Grain sizes varied from .55 to .79 mm and pore Reynolds numbers were in the range of .001 to 20,000. The data are divided into two flow regimes and separate equations are proposed for each regime. Surface roughness is incorporated in the equations for the high Reynolds number regime. The correlations also account for the wall effect.
