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...

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.

In this study, we aim to assess the level of risk of destabilization for infrastructure built on permafrost in the French Alps and to discuss the adaptation and mitigation strategies developed by stakeholders. The analysis combines an inventory of the high mountain infrastructure with several data layers-including two recently developed regional maps of permafrost-analysed within a Geographic Information System.
