Impacts of drying–wetting cycles on rhizosphere respiration and soil organic matter decomposition [PDF]
, 2013 Drying-wetting cycles influence both soil organic matter (SOM) decomposition and rhizosphere processes. Rhizosphere processes also affect SOM decomposition through rhizosphere priming. However, little is known about how drying-wetting cycles regulate SOM

Uranium storage mechanisms in wet-dry redox cycled sediments
Water Research, 2019 Biogeochemical redox processes that govern radionuclide mobility in sediments are highly sensitive to forcing by the water cycle. For example, episodic draining and intrusion of oxidants into reduced zones during dry seasons can create biogeochemical seasonal hotspots of enhanced and changed microbial activity, affect the redox status of minerals ...

Damage to the Microstructure and Strength of Altered Granite under Wet–Dry Cycles [PDF]
Symmetry, 2018 This paper presents an analytical method for surrounding rocks in symmetrically shaped tunnels or roadways, with the symmetrical rise and fall of groundwater over a certain period. The influence of reservoir water level on wet–dry cycles were studied.

Advances in Civil Engineering, 2019 Compacted soil is widely used in road and railway subgrade, while alternation of seasons can cause fluctuations in moisture content of soil (i.e., wetting-drying cycles) and influence the performance of soil.

Effect of drying-wetting cycles on triaxial compression mechanical properties of sandstone [PDF]
, 2016 To investigate the geological hazards caused by the action of drying-wetting cycle on rocks, we conducted a conventional triaxial compression test on sandstone under a high number of repeated drying-wetting cycles.

Effect of wet-dry cycles on shear strength of residual soil
Soils and Foundations, 2021 In order to investigate the relationship between the shear strength of residual soil and the number of repeated wet-dry cycles it underwent, the direct shear for different water content, different numbers of wet-dry cycles and different vertical stresses were examined.
