Risk management

R1 – Data collection

There are two types of vulnerability that are:

  • physical vulnerability that relates to infrastructure to the Rocky risk resistance. This resistance is dependent on the intrinsic properties of this infrastructure subject to a fall of stones, blocks or rock masses. This subsequently determines the level of the consequences and potential impacts. A first action is to expand infrastructure strength classes or their mechanical susceptibility to the fall of Rocky elements;
  • the social, economic and environmental vulnerability that integrates the infrastructure into a territory. The principle is to analyse the impacts of disturbances generated on infrastructure by the Rocky risk. Follows the concept of resilience or ability of the infrastructure to recover its performance. Note, however, that transport infrastructure fit into a network and this is the functional performance of the network that must be recovered. Action is to carry on taking account of the impacts for the operation of infrastructure and a given territory.
