Effect of kaolinite and Ca-montmorillonite on the alleviation of soil water repellency

Plant, Soil and Environment, 2004
The effects of adding 1-3% (weight) kaolinite or Ca-montmorillonite on the wettability of silica sand, made highly water repellent with stearic acid, was studied during wetting and prolonged drying phases at 50°C.

Effect of Structure on Vertical and Horizontal Wicking Performance Concerning Jute (Chorchorus Olitorius) and Water

Journal of Natural Fibers, 2022
Vertical and horizontal wickings were studied for jute, a lingo-cellulosic natural fiber, as fiber, yarn, woven fabric, and nonwoven. The effect of yarn parameters (linear density, twist density, and tension), fabric type (plain woven, twill woven, and ...

Electric fields in plasmas under pulsed currents

, 2007
Electric fields in a plasma that conducts a high-current pulse are measured as a function of time and space. The experiment is performed using a coaxial configuration, in which a current rising to 160 kA in 100 ns is conducted through a plasma that ...

Alterations in aggregate characteristics of thermally heated water-repellent soil aggregates under laboratory conditions

Journal of Hydrology and Hydromechanics, 2023
The heat generated during wildfires modifies soil characteristics, including soil water repellency (SWR) and the water stability of aggregates, which are known to be interrelated.

Anisotropic Wetting Property of Superhydrophobic Surfaces and Electrokinetic Flow on Liquid-Filled Surfaces [PDF]

, 2019
Understanding the wetting property of rough surface is critical in guiding droplets and novel superhydrophobic surface design. The Cassie-Baxter model and Wenzel model are always used to describe the totally non-wetting and completely wetting states ...

Water stable aggregates of Japanese Andisol as affected by hydrophobicity and drying temperature

Journal of Hydrology and Hydromechanics, 2014
Hydrophobicity is a property of soils that reduces their affinity for water, which may help impeding the pressure build-up within aggregates, and reducing aggregate disruption.

Water repellency in forest soils affected by fires and agricultural soils with different agricultural management and abandonment

Cuadernos de Investigación Geográfica, 2013
Soil water repellency determines the water available in the soil system, the runoff generation and the geomorphologic processes. This study examines the soil wettability during the summer of 2008 and 2009 in forest soils with different fire history, and ...

Development of a universal microinfiltrometer to estimate extent and persistence of soil water repellency as a function of capillary pressure and interface chemical composition

Journal of Hydrology and Hydromechanics, 2020
Microinfiltrometers to assess soil water repellency (SWR) are limited to small tension ranges and have different technical setups, hindering a comparison between results from different laboratories.

The initial stages of cave formation: Beyond the one-dimensional paradigm

, 2010
The solutional origin of limestone caves was recognized over a century ago, but the short penetration length of an undersaturated solution made it seem impossible for long conduits to develop.
