Qualitative risk assessment and strategies for infrastructure on permafrost in the French Alps
International audience In the current context of climate change, high Alpine rock slopes and surface deposits are affected by a series of geomorphological processes whose evolution is partly conditioned by permafrost warming and thawing. This degradation directly impacts infrastructure in high mount...

We update a destabilization risk index previously developed to identify and rank infrastructure at risk with a hazard characterisation and a vulnerability diagnosis, based on newly available data. The most at-risk infrastructure according to this new risk index are compared with the strategies implemented by the stakeholders to adapt the foundation, reinforce the ground, reduce heat transfer in depth, or monitor the evolution of the ground. Most of the strategies used on the most at-risk cases are reactive to repair the infrastructure after a destabilization.

International audience In the current context of climate change, high Alpine rock slopes and surface deposits are affected by a series of geomorphological processes whose evolution is partly conditioned by permafrost warming and thawing.
