Water migration in unsaturated partially hydrophobic soils
This article presents new insights into effects of hydrophobic particles on water migration in fine graded soils. The experimental setup for this study uses a column of soil instrumented with sensors that allows direct measurements of soil water content at different heights of the column during capi...
