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

Journal 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

Soil 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

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.

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

علوم 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

Ciência 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

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

Journal 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.

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

Nanomaterials, 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 ...

Seepage Characteristics and Failure Prediction during the Complete Stress–Strain Process of Limestone under High Water Pressure

Applied Sciences, 2022
The seepage characteristics during the complete stress–strain process of limestone under high water pressure were simulated via an experimental study of limestone post-peak penetrating behavior, and an approach to predict the formation of the seepage ...

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.

Impact of duration of land abandonment on soil properties

Journal of Hydrology and Hydromechanics, 2023
Abandonment of agricultural fields triggers the ecosystem recovery in the process referred to as secondary succession. The objective of this study was to find the impact of secondary succession during 12 years lasting abandonment of agricultural fields ...
