Consideration of protection works in hazard assessment - A case study

摘要

The paper describes an approach that makes it possible to consider protection works in hazard assessment properly. With the help of event trees the probability of flood events is combined with the failure probability of protection works. Probability of flood events is studied with classical methods of hydrology. Failure probability of protection works is examined by means of a semi-probabilistic approach respectively by expert judgement. Hydraulic modelling of different flood scenarios allows to compare hazard zones with and without consideration of protection works.
