Water-repellent soil and its relationship to granularity, surface roughness and hydrophobicity: a materials science view [PDF]
, 2005 Considerable soil water repellency has been observed at a wide range of locations worldwide. The soil exhibiting water repellency is found within the upper part of the soil profile.

Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]
, 2011 The wettability of soil is of great importance for plants and soil biota, and in determining the risk for preferential flow, surface runoff, flooding,and soil erosion. The molarity of ethanol droplet (MED) test is widely used for quantifying the severity

Implications of ideas on super-hydrophobicity for water repellent soil [PDF]
, 2007 Water repellence is an important factor in soil erosion due to its role in inhibiting the re-establishinent of vegetation after fire and due to its enhancement of run-off.

Effects of hydrophobicity on splash erosion of model soil particles by a single water drop impact [PDF]
, 2013 Raindrop impact can be a major contributor to particle mobilization for soils and other granular materials. In previous work, water repellent soils, comprised of hydrophobic particles, have been shown to exhibit greater splash erosion losses under ...

How roughness controls the water repellency of woven fabrics
Materials & Design, 2020 The coming ban on substances of high environmental concern used to provide water repellency to fabrics creates new challenges for the textile industry. Here we show that the design of the texture of woven fabrics is an important parameter to play with in

Effect of Biomass-Burning Emissions on Soil Water Repellency: A Pilot Laboratory Study
Fire, 2021 While western U.S. wildfires have increased in intensity and scale, their impacts on soil chemical composition and hydraulic processes have received little attention, despite increasing erosion, surface runoff and flooding.

Journal of Hydrology and Hydromechanics, 2017 This study explored the effect of soil water repellency (SWR) on soil hydrophysical properties with depth. Soils were sampled from two distinctly wettable and water repellent soil profiles at depth increments from 0-60 cm. The soils were selected because
