We present a review and comparison of different models representing the frequency dependence of the soil electrical parameters (conductivity and permittivity). These models are expressed in terms of curve-fit expressions for the soil conductivity and relat ...
The paper presents an experimental and modelling approach for the soil water retention behaviour of two deformable soils. The objective is to investigate the physical mechanisms that govern the soil water retention properties and to propose a constitutive ...
This paper aims to identify and quantitatively evaluate various critical mechanisms associated with the processes of desiccation shrinkage and cracking in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the variou ...
The paper discusses the effect of frequency dependence of soil electrical parameters (also called soil dispersion) on lightning currents induced on the shield of buried cables. To this aim, a full-wave approach based on the finite element method is used in ...
Suitable developments of sustainable energy sources are drawn by analysing the Energy sector, considering environmental, economic and social aspects. The particular example of Switzerland is detailed with a focus on the energy consumption in the buildings. ...
Compacted MX-80 bentonite is a potential backfill material in radioactive-waste repositories. Pore space in MX-80 has been the subject of considerable debate. 3D reconstructions of the pore space based on tomographic methods could provide new insights into ...
Background: Monitoring the properties of dissolved organic carbon (DOC) in soil water is frequently used to evaluate changes in soil quality and to explain shifts in freshwater ecosystem functioning. Methods: Using >700 individual soils (0-15 cm) collected ...
This paper aims to identify and evaluate various critical mechanisms associated with the processes of desiccation shrinkage in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the various stages of drying shrinkage ...
In the last decades the design of stepped spillways regained some interest because of their suitability with new construction methods including gabions. The hydraulic performances of gabion stepped weirs were investigated experimentally in terms of the flo ...
This paper explores the influence of the confining stress on rock fragmentation under the cutter of tunnel boring machine (TBM) by indentation test. Acoustic emission (AE) system was employed for real-time monitoring the rock fragmentation process during t ...
