In this paper, we study the drying of water-saturated porous polydimethylsiloxane (PDMS) elastomers with closed porosity in which the evaporation of water is possible only via the diffusion across the PDMS. Starting from water/PDMS emulsions, we fabricate soft macroporous samples with different pore diameter distributions and average diameters rang...
Long-term delayed strain of concrete impacts the lifetime of civil engineering structures such as dams, nuclear power plants, nuclear waste storage tunnels or large bridges. In design practice, the long-term delayed strain of concrete is decomposed into four components: autogenous shrinkage, basic creep, drying shrinkage and drying creep. The four ...
Future climate scenarios for the Mediterranean region indicate a possible decrease in annual precipitation associated with an intensification of extreme rainfall events in the coming years. A major challenge in this region is to evaluate the impacts of changing precipitation patterns on extreme hydrological events such as droughts and floods. For t...

Attribution of trends in streamflow is complex, but essential, in identifying optimal management options for water resources. Disagreement remains on the relative role of climate change and human factors, including water abstractions and land cover change, in driving change in annual streamflow. We construct a very dense network of gauging stations...
La cohésion des tufs algériens souvent utilisés en technique routière baisse quand le degré de saturation augmente et disparaît lors de la saturation totale du matériau. La présente étude expérimentale multi-échelle appliquée sur des échantillons séchés dans différentes conditions tente d'expliquer l'origine du durcissement et l'existence d'une ten...
Drought is the main abiotic stress worldwide affecting harvest quality and quantity of numerous crops. To enable better water management, low field NMR (nuclear magnetic resonance) relaxometry was assessed as a developmental marker and a new method for early detection of water deficiency. The effect of a foliar biostimulant against water stress was...
Drought management plans require an overview of future climate conditions for ensuring long term relevance of existing decision-making processes. To that end, 'bottom up' approaches have been developed to best match decision-making needs as catchment intrinsic sensitivity to climate change. Due to severe low-flow and drastic snowpack decrease, Medi...
