In the context of inspection and maintenance actions for beach walkways in North Portugal, some samples wood used their construction were collected – <em>Pinus</em> <em>sylvestris</em> wood, widely applied country. The sustainability over natural coastal areas is very dependent on material durability. One main problems timber to build those structures its behavior under ...

This work investigates the equilibrium stage of crack propagation a fine-grained soil after several drying and wetting cycles (shrinkage swelling hysteresis). is found to be crucial in practical engineering since continues show its irreversible hydraulic settlement, which potential risk for some severe structural damages. The shrinkage area were determined by using image processing method. For ...

The effects of a sulfonated oil (SO) stabiliser on the swell–shrink properties an expansive soil were investigated through cyclic wetting–drying tests. action led to reconstruction microstructure by inducing clay particle aggregation. Accordingly, greater number applied cycles, lower potential up fourth cycle, beyond which swelling and shrinkage strains attained elastic equilibrium. At any give...

The decay of soil strength and the change infiltration characteristics caused by dry wet cycle effect generated rainfall-evaporation process are important factors that induce slope instability. How to consider water-soil characteristic curve hysteresis on transient stability is key solve this problem. In paper, analysis slopes considering carried out based Geo-Studio. results study showed safet...

The present paper demonstrates how a natural crack mosaic resembling random tessellation evolves with repeated 'wetting followed by drying' cycles. system here is network in drying colloidal material, for example, layer of mud. A spring model used to simulate consecutive wetting and cycles mud layers until the matures. simulated results compare favourably reported experimental findings. evoluti...

This paper proposes a wetting and drying treatment for the piecewise linear Runge–Kutta discontinuous Galerkin approximation to the shallow water equations. The method takes a fixed mesh approach as opposed to mesh adaptation techniques and applies a post-processing operator to ensure the positivity of the mean water depth within each finite element. In addition, special treatments are applied ...

Thirty three re-wetting tests were conducted at different combinations of temperatures (5.746.3C) and relative humidites (48.2-88.6%) with barley. Two most commonly used thinlayer drying and rewetting models i.e. Page and Diffusion were compared for their ability to the fit the experimental re-wetting data based on the standard error of estimate (SEE) of the measured and simulated moisture cont...
