Predicting and managing water resources at regional scale under different climate and socio-economic scenarios is crucial to support drinking water supply and other sectors. At the same time, protecting rivers and wetlands from pollutions and droughts is essential and must include groundwater given its contribution to surface water. Yet, assessing ...
Poursuite des études liées à la tempête Alex par le CNRS: 1/ Cartographie des cumuls de pluie dans la vallée lors de la tempête Alex; 2/ Modélisations hydrologiques des débits de la Roya en France-Italie; 3/ Transport sédimentaire en Roya: retour d'expérience de 7 années de suivi et modélisation des flux en contexte de changement climatique
isiWithin hilly agricultural landscapes, topography induces lateral transfers of runoff water, so-called interplot hydrological connectivity. Runoff water from upstream plots can infiltrate downstream plots, thus influencing the water content in the root zone that drives crop functioning. The current study aims to comprehensively investigate the im...
In a recent paper, a consistency correction for the water flux using multiple flow direction (MFD) algorithms that account for exchanges between a cell and its neighbors was proposed, thanks to a reinterpretation of the MFD as a well chosen discretization of the Gauckler-Manning-Strickler continuous equation. Building on those results, we introduce...

This research develops a conceptual model of a karst system subject to mountain permafrost. The transient thermal response of a frozen rock cleft after the rise in the atmospheric temperature above the melting temperature of water is investigated using numerical simulations. Free convection in liquid water (i.e. buoyancy-driven flow) is considered....
