CP52A:
Extreme Sea Levels and Coastal Flood Risk II

Session ID#: 92809

Session Description:
Extreme sea levels emerge as a combination of regional mean sea level, astronomic tides, storm surges, a dynamic wave component, and, in deltas and estuaries, river discharge. Inundation of coastal areas arises from the superposition of these components and can lead to moderate (but frequent) impacts related to tidal flooding, or devastating social, economic, and environmental consequences due to rare extreme events. The 2017 and 2018 hurricane seasons in the North Atlantic were only the latest reminders of the vulnerability of low-lying densely populated and highly developed coastlines. In order to plan effective adaptation to coastal flooding hazards it is essential to improve the understanding of the links between different sea level components, and how they are modulated by climate change and variability, individually and in combination. This session seeks contributions from studies that have: (i) examined changes in any of the sea level components outlined above and their links to climate change and variability (past and future), (ii) undertaken statistical or process-based model analyses of extreme sea levels or its individual components, (iii) assessed how changes in sea level modulate coastal flood risk, (iv) or taken an integrated approach toward flood hazard and vulnerability evaluation of complex coastal systems.
