Coastal Flood Hazard Workshop: Advancements in Bridging Scales and Disciplines for Future Risk Assessment

Global mean sea level has risen 103 mm since 1993 (Willis et al. 2023), and observation-based extrapolations using current sea level trends and acceleration from satellite altimetry (Hamlington et al. 2022) are near or exceeding the higher-end climate model projections contained in the Intergovernmental Panel on Climate Change Sixth Assessment Report (Fox-Kemper et al. 2021). In many areas, high-tide flooding due to rising sea levels is already occurring and is predicted to become more frequent in the coming decades (Thompson et al. 2021). Coastal flood hazard forecasting (i.e., short-term predictions) and projection skill depend on the ability to simulate local dynamics, natural variability, and climate extremes, while long-term projections also require simultaneously integrating increasing risk associated with future conditions in a changing climate.
