COMPACTION EFFECTS ON THE HYDRAULIC CONDUCTIVITY OF A CLAY SOIL

ESTHER DOUGLAS, E. McKyes

Abstract

Unsaturated hydraulic conductivities of laboratory-compacted samples of Ste. Rosalie clay were measured, and the values obtained were corrected for the effective changing porosity under increasing pressure gradients. An equation is presented that permits predicting the corrected hydraulic conductivity as a function of compaction in terms of porosity.
