In high latitudes and high elevation the warming rate is faster than anywhere else on the planet, with large implications for the cryosphere: The snowpack is changing, the snow-melt period is shifting, the permafrost is thawing and the glaciers are retreating. These changes have a significant impact on hydrological regimes with mainly an earlier spring snow-melt freshet, an expansion of the active layer, and a change in the contribution of ice-melt to the total streamflow. In the Alps, these changes have large implications for the water availability for humans and the ecosystems, the flood risks, and activities relying on summer low flows. However, the impact of the cryospheric change on hydrology in the Alps is not well quantified. In this talk, after an overview of (i) my previous research on hydrological modeling in cold environments (Svalbard, Alps, Canada) and (ii) my current research on the contribution of glacier melt for the Rhone Basin streamflow, I will present my research perspectives on the impact of cryosphere on water resources in the Alps.
