Risk assessment of infrastructure destabilisation due to global warming in the high French Alps
Poster Due to ongoing global warming, high alpine environments are affected by significant changes, such as glacial retreat and permafrost warming, which can trigger mass movements in rock slopes or superficial deposits. These processes generate a risk of direct destabilisation for high mountain inf...
