    The project IRTORISKI studied the use of Event Tree Analysis (ETA) to assess the vulnerability and adaptation of flood prone areas. As a starting point for the ETA three flood scenarios were defined: Scenario 1: R=50 in current climate with current flood protection Scenario 2: R=30 in future climate of 2020-2050 with current protection Scenario 3: R=30 in future climate with new flood protection In order to assess the direct cost consequences the annual probabilities for the current climate are first assessed based on the annual cumulative distribution function as P(Q > qR) = 1 - F(Q < qR) = 1/R. The consequences of a significant flood, such as R50 of today, are economic (direct/indirect), health, environment, and social consequences. In the paper, a full ETA is described quantifying the annual risks related to the above scenarios where the new flood protecting measure considered is the construction of an absorption area.
