Robust adaptation to hydrological climate change requires an assessment of possible and futures at different scales. Explore2 is a recent multimodel ensemble projections developed accompany local plans for metropolitan France Corsica, 550,000 km2 wide territory with large diversity regimes (Sauquet et al. 2024). The provides transient daily river flow more than 4’000 locations on French rivers. Projections have been obtained three RCP emission scenarios 4 9 models (HMs) driven by...
This paper deals with the identification of extreme multiscale flooding events in Alpine conurbation Grenoble, France. During such events, typically over one to several days, organization space and time generating hydrometeorological situation triggers concurrent reaction varied sets torrents main rivers creates diverse socioeconomic damages disruptions. Given limits instrumental data long run, particular at torrent scale, we explore potential a database reported flood study Metropolitan...
The current operational hydrological modelling of mountainous catchments mostly relies on conceptual and semi-distributed models, which are calibrated based historical discharge measurements. As a consequence, in spite their good performance seasonal river runoff prediction, they often fail to project the impact climate change cycle over decades. This is due limited representation physical processes inability simulate water paths modification. To overcome such limitations, we applied...
Abstract. From the micro- to mesoscale, water and energy budgets of mountainous catchments are largely driven by topographic features such as terrain orientation, slope, steepness, elevation, together with associated meteorological forcings precipitation, solar radiation, wind speed. Those govern snow deposition, melting, transport, which further impacts overall cycle. However, this microscale variability is not well represented in Earth system models due coarse resolutions. This study...

Abstract. In this article we study the atmospheric conditions at origin of damaging torrential events in Northern French Alps over long run, using a database reported occurrence flooding Grenoble conurbation since 1851. We consider seven variables that describe nature air masses involved and possible triggers precipitation. Using both 20CRv2c ERA5 reanalyses, try to isolate associated with events, by objectively determining which them differ particularly from climatology dates events. This...
Abstract. The Alpine region is strongly affected by torrential floods, sometimes leading to severe negative impacts on society, economy, and the environment. Understanding such natural hazards their drivers essential mitigate related risks. In this article we propose a statistical method based mere discriminative index objectively isolate atmospheric variables associated with events long return periods. applied Grenoble Metropolitan area in Northern French Alps using list of dates damaging...
<p>Mountain regions represent a particular challenge for critical zone modelling as snowpack interacts with soils, vegetation, surface water and atmosphere plays primary role on the transfers but also carbon nitrogen cycles. Indeed, in these environments ecosystems are adapted to snow regime under change due rise 0°C isotherm. In addition, atmospheric deposition, product of industrial activity carried by valley winds mesoscale circulation, already impacts some...
