Slippery liquid‐infused porous surfaces: The effect of oil on the water repellence of hydrophobic and superhydrophobic soils

European Journal of Soil Science, Volume 72, Issue 2, Page 963-978, March 2021., 2021
Abstract Soil wettability is important for understanding a wide range of earth system processes, from agricultural productivity to debris flows and sediment fan formation. However, there is limited research considering how soil–water interactions, where the soil grains are naturally hydrophobic, might change in the presence of oil from natural ...

Cover systems with synthetic water‐repellent soils

Vadose Zone Journal, Volume 20, Issue 1, January/February 2021., 2021
Abstract A cover system is a crucial component of engineered landfills, to minimize water percolation into the underlying waste. Capillary barriers are an alternative cover system, which has been widely used in the arid and semiarid regions as no cohesive, low‐permeability materials are used.

Evaluation of soil properties in variously aged Scots pine plantations established on sandy soil

Journal of Hydrology and Hydromechanics, 2021
Pines are widely planted for sand dune stabilization and their cultivation results in the changes in physical, chemical, hydro-physical and water repellency properties.

Wettability decay in an oil-contaminated waste-mineral mixture with dry-wet cycles [PDF]

, 2015
The dependency of soil particle wettability on soil water content implies that soils subjected to drying-wetting cycles become wettable with wetting and water repellent with drying.

Processes in model slopes made of mixtures of wettable and water repellent sand: Implications for the initiation of debris flows in dry slopes [PDF]

, 2015
Debris flows in slopes initially dry, such as post-wildfire debris flows, are initiated by surface runoff and sediment bulking due to reduced infiltration.

Strength and Expansion and Deformation Characteristics of Modified Expansive Soil by Octadecylamine

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Octadecylamine was used as a primary water repellent and mixed into the remodeled expansive soil, and modified expansive soils with different water contents and octadecylamine contents were configured. The water repellency level of the modified expansive soil was determined by the drip penetration time method, the corresponding free, unloaded, 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

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-establishment of vegetation after fire and due to its enhancement of run-off.

Effect of hydrocarbonic pollutants on the stability and soil water repellency intensity: A case study in Bandar Abbas Oil Refinery, Hormozgan province, Iran

Environmental Health Engineering and Management, 2022
Background: The contamination of soil and water with hydrocarbonic pollutants is a major environmental problem. Soil water repellency will interrupt water infiltration, and may decline plant growth and potentially trigger soil erosion.

Fire-induced changes in soil properties depend on age and type of forests

Journal of Hydrology and Hydromechanics, 2022
Wildfires affect different physical, chemical, and hydraulic soil properties, and the magnitude of their effects varies depending on intrinsic soil properties and wildfire characteristics.
