Climate Scenarios for Coastal Flood Vulnerability Assessments: A Case Study for the Ligurian Coastal Region

Extreme sea levels and coastal flooding are projected to be among the most uncertain severe consequences of climate change. In response, a wide development vulnerability assessment methodologies has been observed in research support societal resilience future flood risks. This work aims explore scope application index-based for assessment, terms their suitability convey information on variations variables potentially leading sea-level changes inundation. For this purpose, InVEST Coastal Vulnerability model was coupled first time with ERA5 reanalysis used develop case study biophysical exposure component Liguria, an Italian region facing Mediterranean Sea. Different scenarios wind speed wave power were created order test sensitivity approach data inputs. The results applicability provide preliminary grasp local Yet, also highlights how method’s aggregation indicator computation processes result its insensitivity variations, therefore unsuitability reproduce scenarios. implications these findings methodology regarding operationalisation discussed.
