“…In this project multivariate statistical models were used to calculate the (joint) probabilities of the occurrence of a range of storm surge (and wave) events (Wahl et al, 2011, failure probabilities were determined, inundation models were applied, and damages in the hinterland were assessed (see Oumeraci et al, 2012 and references therein for an overview). Such risk-based approaches will likely become more important in the future but are not yet feasible to be applied widely to entire coastline stretches.…”

Abstract. Integrated risk assessment approaches to support coastal managers' decisions when designing plans are 10 increasingly becoming an urgent need. To enable efficient coastal management, possible present and future scenarios must be included, disaster risk reduction (DRR) measures integrated, and multiple hazards dealt with. In this work, the Bayesian Network approach to coastal risk assessment was applied and tested at two Mediterranean sandy coasts (Tordera Delta in Spain and Lido degli Estensi-Spina in Italy). Process-oriented models are used to predict hazards at the receptor scale based on a large number of storm characteristics. Hazards are converted into impacts through vulnerability relations. A Bayesian 15Network integrates all results to link forcing characteristics with expected impacts through conditional probabilities. The tool has been proven successful in reproducing current coastal responses at both sites. It has also shown great utility for scenario comparisons, and is able to output significant impact change trends, despite the inherent uncertainties of the approach. This work highlights the advantages of using such a tool for present and future coastal risk assessment and planning. 20

About Flood RiskClimate change and sea level rise, storm surges and hurricanes, sustainability and preparedness are keywords when dealing with safety issues and flood protection along the world's coasts and estuaries. Scientific investigations and political discussions of the related questions are manifold and have looked into various aspects of coastal flood risk. However, the definition of "risk" alone has kept scientists busy all over the world and whilst disputes about its meaning can be found in literature, an easy-to-apply generic definition is yet simply not available.The term "risk" has been developed involving a wide range of disciplines all of which seem to have different viewpoints and definitions of risk. It is therefore inevitable to define its meaning before commencing any risk assessment or risk management attempts. The papers in this issue deal with various aspects of coastal flood risk in general and most of them use an engineering approach to risk which is defined here as the probability of a flood times its consequences. Whilst this seems a straightforward definition it implies numerous questions which have not been answered and some of which have not even been addressed yet. What con-1502001-1
