Supporting data for “Effect of interfacial properties on soil water infiltration”

Hydrophobic soils have a low affinity for water and inhibit water infiltration. Soil hydrophobicity is related to undesirable consequences such as enhanced soil erosion and increased risk of debris flows. However, the waterproof properties of hydrophobized soils delivers favorable applications as shallow covers or barriers. The application of hydrophobized soils in geotechnical engineering is constrained by the water entry pressure (the pressure at which water breaks into the pores). This thesis provides various insights into the effect of interfacial properties on soil water infiltration. The results provide a fundamental basis to model and design hydrophobized soils for ground applications. Uniquely, it also demonstrates the conditions under which water infiltration can be controlled in soils, by testing methods that promote or hinder water infiltration in hydrophobized soils.
