ETGR - Torrent erosion, snow and avalanches

  • Department : Eaux
  • Center : Grenoble

This research unit aims to devise tools for engineering and preventing natural hazards in mountains (avalanches, wind-driven snow movements, floods, debris flows, rockfalls and hazards relating to glaciers). It performs basic exploration into the formation, rheology and dynamic of flows.


Report - Meeting CCR CAT – 8th June 2017

CCR, the insurer partner in NAIAD (Nature Insurance Value: Assessment and Demonstration) H2020 European project had organized the 8th June 2017, his annual meeting. One of the most important meeting in the French insurance market.

This meeting was dedicated to a “Global view of natural catastrophes through feedbacks on how to limit impact of natural hazards on business interruption”. It was a day of exchange on knowledge on natural disasters and their consequences within the insurance sector.

David Moncoulon (CCR) and Cécile Hérivaux (BRGM) have done a general presentation of NAIAD, as an example of future issue. They highlighted the importance of the NAIAD interdisciplinary approaches: this project gathers 11 European countries, 23 partners, 9 DEMOs sites, and water-related hazards. They also presented the 2 French sites of demonstration (DEMOs - located in South of France, the Brague catchment (near Nice & Antibes) and the Lez catchment (near Montpellier) as practical examples to assess and demonstrate the insurance value of ecosystem (IVE).

Jean-Marc Tacnet and Roxane Marchal (IRSTEA), David Moncoulon (CCR) and Cécile Hérivaux (BRGM) have been the representatives of the NAIAD partners to disseminate information and involve the insurance sector in this project and particularly into an European Insurance Survey. NAIAD partners will interview insurers on their current knowledge on nature-based solutions. It will help us in the objective to develop methods and a new European legal framework well-tailored to the insurance sector’ needs and to implement the IVE.



The ETGR Research Unit

Physical and digital modelling is performed here, along with field and laboratory experiments. The other spheres of activity are: defence techniques, mapping and the development of information systems for managing natural hazards.

The unit manages tow databases on avalanches: EPA (Permanent Avalanche Survey) and the CLPA (Avalanche Map). It also carries out expert appraisals in France and abroad, helps compile technical guides and undertakes educational and public awareness actions. It draws on the knowledge of teams from other disciplines in the OHAX (Hydrology and Hydraulic structures) and REBX (water supply systems, purification and quality) research units to work around the RIVAGE (Hazards relating to rapid gravity movements, security of hydraulic works and vulnerabilities) research topic. In the organisational chart above, people whose names appear in italics work on the RIVAGE RT but are not part of the ETNA RU.
