A Framework for Risk Management in Rockfall Protection

Rockfalls represent a constant threat to the facilities, infrastructure and inhabit-ants. Therefore, it is necessary to map the rockfall hazard area and to carry out the risk assessment. In the Republic of Croatia there is no systematic data acquisition of rockfalls. There is also no rockfall classification system adjusted for Croatian Karst. In this paper a Framework for Risk Management in Rockfall Protection in Croatian Karst is presented, which enables a better understanding of the problem and the cooperation of all participants in the project. Decision-making process, necessary for complex decisions, depends on the systematic study of influential factors, the adequacy and quality of information, the number of alternatives, and the use of appropriate models and techniques for selecting optimal alternative. Quantitative risk analysis is carried out if there is a possibility of estimating the probability of a certain event, based on available information about similar events that occurred in the past or on information collected in any other way and also based on personal experience. In the absence of such experience proposed framework allows a qualitative risk analysis with constant control of the consistency of subjective decision- making.
