Uranium storage mechanisms in wet-dry redox cycled sediments
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 ...

Failure mechanism of canal slopes of expansive soils considering action of wetting-drying cycles
The canal of expansive soils is in the state of wetting-drying cycle because of seasonal water level fluctuations, and its slope instability is easily induced.

Analysis of changes in volume and propagation of cracks in expansive soil due to changes in water content [PDF]
Expansive clay soils are a problem for agriculture and engineering because they are susceptible to change in volume due to seasonal variation in water content and temperature.

Giant osmotic pressure in the forced wetting of hydrophobic nanopores [PDF]
The forced intrusion of water in hydrophobic nanoporous pulverulent material is of interest for quick storage of energy. With nanometric pores the energy storage capacity is controlled by interfacial phenomena.

Network modelling of the influence of swelling on the transport behaviour of bentonite [PDF]
Wetting of bentonite is a complex hydro-mechanical process that involves swelling and, if confined, significant structural changes in its void structure.
