Initial water repellency affected organic matter depletion rates of manure amended soils in Sri Lanka

open access: yesJournal of Hydrology and Hydromechanics, 2014
The wetting rate of soil is a measure of water repellency, which is a property of soils that prevents water from wetting or penetrating into dry soil.

Variability of water repellency in sandy forest soils under broadleaves and conifers in north-western Jutland/Denmark

open access: yesSoil and Water Research, 2008
Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been known to occur on a wide range of sites under a variety

Effect of Biomass-Burning Emissions on Soil Water Repellency: A Pilot Laboratory Study

open access: yesFire, 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.

Dynamic measurements and wettability phenomena in mesoporous anodic films prepared on 1050 and 2024T3 aluminium alloys [PDF]

open access: yes, 2016
The wettability of mesoporous anodic films has until now been a parameter rarely studied although it remains crucial especially for sealing treatment following anodising.

Comparison Methods of Determining the Degree of Hydrophobicity Based on the Measurement of Soil-Water Contact Angle

open access: yesعلوم آب و خاک, 2021
The contact angle is a numerical index of differentiation between hydrophilic and hydrophobic soils. The objectives of this research are: 1) assessing different methods such as capillary rise, the molarity of ethanol droplet, repellency index, and ...

Soil hydrophobicity: comparative study of usual determination methods

open access: yesCiência Rural, 2015
Hydrophobic or water repellent soils slowly absorb water because of the low wett ability of the soil particles which are coated with hydrophobic organic substances. These pose significant effects on plant growth, water infiltration and retention, surface

The Applicability of a Drop Penetration Method to Measure Contact Angles on TiO2 and ZnO Nanoparticles

open access: yesNanomaterials, 2020
In this study, six solvents (water, diiodomethane, bromonaphthalene, formamide, ethanol and ethylene glycol) were examined for three nanoparticle substrates, zinc oxide and titanium dioxide (21 nm and 100 nm), with the goal of assessing the suitability ...

Impact of secondary succession in abandoned fields on some properties of acidic sandy soils

open access: yesJournal of Hydrology and Hydromechanics, 2020
Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage.

Time-dependent hydrophobic characterisation of granular materials synthesised with commercial chemical agents [PDF]

open access: yesE3S Web of Conferences, 2023
The impact of hydrophobicity on unsaturated granular materials is important because suction is a function of the degree of saturation as well as the surface tension and contact angle of the water menisci.

Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]

open access: yes, 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
