Influence of Soil Wetting and Drying Cycles on Soil Detachment

AgriEngineering, 2022
Agricultural soils undergo periods of saturation followed by desiccation throughout the course of a growing season. It is believed that these periods of wetting and drying influence soil structure and may affect the rate of soil detachment.

Damage Features of Altered Rock Subjected to Drying-Wetting Cycles [PDF]

Advances in Civil Engineering, 2018
An abandoned open pit was used as a tailing pond for a concentrating mill, with the height of the water surface subject to cyclic fluctuation. The effects of drying and wetting cycles on the mechanical parameters of pit rock were tested.

Cracking of silty mudstone subjected to wetting-drying cycles

Journal of Rock Mechanics and Geotechnical Engineering
Cracking affected by wetting-drying cycles is a major cause of shallow failure of soft rock slopes. Knowledge of rock tensile properties and cracking behaviors helps better assess the stability of soft rock slopes. This study aims to examine the cracking

Visualizing RNA polymers produced by hot wet-dry cycling [PDF]

Scientific Reports, 2022
Abstract It is possible that the transition from abiotic systems to life relied on RNA polymers that served as ribozyme-like catalysts and for storing genetic information. The source of such polymers is uncertain, but previous investigations reported that wet–dry cycles simulating prebiotic hot springs provide sufficient energy to drive ...

Evolution of desiccation cracking behavior of clays under drying-wetting cycles

Rock and Soil Mechanics, 2021
Soils usually experience multiple drying-wetting cycles in nature, which can have a significant impact on the engineering properties of soils. Laboratory tests were conducted to investigate the effect of drying-wetting cycles on the initiation and ...

Sustained wet–dry cycling on early Mars

Nature, 2023
The presence of perennially wet surface environments on early Mars is well documented1,2, but little is known about short-term episodicity in the early hydroclimate3. Post-depositional processes driven by such short-term fluctuations may produce distinct structures, yet these are rarely preserved in the sedimentary record4.

An insight into drying-wetting cycles of peat

E3S Web of Conferences, 2023
A relevant part of the geotechnical infrastructure in the north of Europe and overseas is built on soft organic soils, including peat. Peat is extremely vulnerable to climate-related hazards as increased temperature accelerates drying, shrinkage and decomposition of the organic matter.
