Any increase in flood frequency or severity due to sea level rise or changes in storminess would adversely impact society. It is crucial to understand the physical drivers of extreme storm surges to have confidence in the datasets used for extreme sea level statistics. We will refine and improve methods to the estimation of extreme sea levels around Europe and more widely. We will do so by developing a comprehensive world map of storm surge distribution (including extremes) for both tropical and extra-tropical cyclones. We will apply statistical methods to both tide gauge data and multi-decadal runs of hydrodynamical numerical models [NERC-NOC, MI]. We will also contribute to the development of a global storm surge climatology, building on the work of the IOC/WMO JCOMM Expert Team for Waves and Coastal Hazards [D8.1] [ NOC, MI] . The results will advance our scientific knowledge of storm surges as well as provide valuable policy guidance to decision makers and planners [D8.12] [NERC-NOC, MI].

Deliverables:

D8.1 Storm surge probability climatology Report: Develop a world map of storm surge distributions and further develop a global storm surge climatology through the JCOMM ETWCH storm surge climatology project (http://noc.ac.uk/science-technology/climate-sea-level/sea-level/skew-surges/storm-surges).PM24

D8.12 Report on AtlantOS fitness for storm surge: Critically assess whether extreme water level can be reliably derived from hydrodynamic model hindcasts and the AtlantOS impact on the assessment quality. PM42
