The publication of a Guidebook dedicated to the analysis and management of ground movement hazards related to under-caved rocky slopes is an opportunity to organize a technical workshop.
This workshop intends to bring together experts, engineers, and stakeholders concerned by under-caved rocky slope hazard.
It will begin with a presentation of the guidebook. Then research studies and practical applications will be exposed. The afternoon will be devoted to analyzing an example of on-site risk management with a visit to an under-caved site. There, the difficulties encountered, the technical solutions provided and the risk management by the community will be discussed.
