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...

Groundwater is a key component for the development of semi-arid areas where surface water resources are scarce. Water managers need knowledge about water reserves to cope with their multiple constraints. In the Merguellil basin (Central Tunisia), the Kairouan plain aquifer supplies water for a rapidly growing irrigated agriculture economy but recha...

In mountainous areas, freezing is a prominent phenomenon for weathering processes in rock walls. A freezing front penetrates rock crack networks and causes its propagation. To study the evolution of rock mass stability, a suitable model of stress generated by freezing in open rock cracks is needed. This stress evaluated by the simple volume expansi...

Excessive CO2 in the present-day ocean-atmosphere system is causing ocean acidification, and is likely to cause a severe biodiversity decline in the future, mirroring effects in many past mass extinctions. Fossil records demonstrate that organisms surviving such events were often smaller than those before, a phenomenon called the Lilliput effect. H...
