To study the strength degradation mechanism of compacted loess during dry-wet cycles, 0–5 cycles tests and many triaxial compression were carried out on with an optimal moisture content. During samples analyzed by nuclear magnetic resonance scanning electron microscopy. Studies have shown that at macro level, increasing numbers wet dry cycle amplitude, cohesive force internal friction angle dec...

Abstract The stability of coal pillar dams is influenced by cyclic fluctuations salty water from underground reservoir. Subjected to long-term drying-wetting cycles in solution, the microstructure and surface topography can be significantly changed which results deterioration mechanical properties. To investigate damage mechanism subjected uniaxial compression test prepared samples were conduct...

Climate and vegetation change are two dominating factors for soil moisture trend. However, their individual contributions remain unknown due to their complex interaction. Here, I separated their contributions through a trajectory-based method across the global, regional and local scales. Our results demonstrated that climate change accounted for 98.78% and 114.64% of the global drying and wetti...

abstract recharge of aquifers by using wastewater, is one of the important and applicable ways for reusing this valuable water resource, especially in arid and semi-arid regions. as the necessity of local practices for finding the proper management strategies and optimum use of recharge systems (conforming to climate, soil, etc.), a preliminary study was carried out. three physical models were ...

In shallow-water models, wetting and drying (WAD) are determined by the total water depth D 1⁄4 0 for ‘dry’ and >0 for ‘wet’. Checks are applied to decide the fate of each cell during model integration. It is shown that with bottom friction values commonly used in coastal models, the shallow-water system may be cast into a Burger’s type equation for D. For flows dominated by D (i.e. jrDj jrH j,...

Abstract Co‐seismic uplift of Kaikōura Peninsula in 2016 has substantially reduced the number wetting and drying cycles that occur on shore platforms newly uplifted incipient marine terraces. A simple empirical model incorporating field laboratory measurements was used to determine frequency cycles. The mudstone supratidal terraces are vulnerable material disintegration slaking through sustaine...
