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.

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

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.

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

open access: yesApplied 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 ...

Hele-Shaw Flow Near Cusp Singularities [PDF]

open access: yes, 2013
This thesis discusses the radial version of the Hele-Shaw problem. Different from the channel version, traveling-wave solutions do not exist in this version.

Impact of duration of land abandonment on soil properties

open access: yesJournal 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 ...

Sterilized Polyhexanide-Releasing Chitosan Membranes with Potential for Use in Antimicrobial Wound Dressings

open access: yesMembranes, 2023
Wound infection is a common complication of chronic wounds. It can impair healing, which may not occur without external help. Antimicrobial dressings (AMDs) are a type of external help to infected chronic wounds.
