Abstract: The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the outcome and the exposure, and then evaluates the consequences of the outcome in terms of economic damages and loss of life. The method lends itself to selecting the best alternative for risk reduction and globally considers the risk from a number of initiating events. This paper presents a methodology for evaluating the seismic component of the risk assessment procedure.
