Role of Caustic Addition in Bitumen-Clay Interactions [PDF]

, 2015
Coating of bitumen by clays, known as slime coating, is detrimental to bitumen recovery from oil sands using the warm slurry extn. process. Sodium hydroxide (caustic) is added to the extn.

Quantitative experimental study on the apparent contact angle of unsaturated loess and its application in soil–water characteristics curve modeling

Vadose Zone Journal, Volume 23, Issue 6, November/December 2024.
Abstract Advancing and receding water contact angles, often denoted as the maximum and minimum apparent water contact angles, are crucial parameters reflecting a soil's water holding capacity. These parameters play an important role in establishing theoretical soil–water characteristic curves (SWCCs) for unsaturated soils.

Continuous Monitoring of Vegetation and Soil Recovery After Eucalyptus grandis Removal in Dense Trees and Shrubs Areas

African Journal of Ecology, Volume 62, Issue 3, September 2024.
ABSTRACT Invasion by invasive alien plants is a global challenge and South Africa has invested billions of Rands to manage invaders through the Working for Water programme. However, regular monitoring after alien plant clearing is hardly done, yet it forms the basis for assessing clearing programme effectiveness, particularly ecosystem recovery ...

Testing soil water repellency in a Sicilian area two years after a fire

Journal of Agricultural Engineering, 2019
The water drop penetration time (WDPT) technique was applied in 2018 to check persistence of soil water repellency (SWR) in a Sicilian mountain area affected by a wildfire on June 2016.

Water repellency in eucalyptus and pine plantation forest soils and its relation to groundwater levels estimated with multi-temporal modeling

Journal of Hydrology and Hydromechanics, 2020
Water repellency makes soils capable of resisting to the penetration of water applied on the surface and inflict various influences on groundwater.

La hidrofobia en los suelos arenosos del parque natural de Doñana [PDF]

, 2002
La hidrofobia, o repelencia al agua que se manifiesta en algunos suelos, dificulta la infiltración del agua, y, consecuentemente, el establecimiento de vegetación.

Effect of wettable and hydrophobic biochar addition on properties of sandy soil

Biologia
Sandy soils have high hydraulic conductivity and low retention ability for water and nutrients, resulting in low fertility. As water retention of coarse-textured soil is substantially more sensitive to the amount of organic carbon than fine-textured ...

Patterns of soil water repellency change with wetting and drying: the influence of cracks, roots and drainage conditions [PDF]

, 2014
The influence of simulated cracks and roots on soil water repellency (SWR) dynamics with and without basal drainage impedance in wetting–drying cycles was investigated in the laboratory experiments.
