Decision-making for the purpose of adaptation to climate change typically involves several stakeholders, regions and sectors, as well as multiple objectives related to the use of resources and benefits. In the case of adapting to extreme events, modelling of the impact pathways and consequences need to be conducted in some way. We explore the role of event tree analysis of extreme events in the context of flood protection of critical infrastructure. Experts representing potentially affected infrastructure services are consulted on the usability of the ETA method for providing structured information on flood scenarios, system impacts and consequences, risks and counter measures. The main users of the analysis results are the asset owners and the local public decision-makers whose joint efforts are usually required to fund and prioritize such measures of adaptation.
