Resilience of art cities to flood risk: A quantitative model based on depth‐idleness correlation

A medium recurrence interval flood in Florence, Italy, results in a recovery time of 351 days for cultural heritage (CH) and causes a loss of approximately 10.5 million visitors annually, with an average annual loss of around 88,000 visitors. This study introduces a novel framework to evaluate flood resilience, indirect impacts, and associated risk in art cities like Florence, which relies heavily on tourism for its economy. The model estimates CH exposure using visitor numbers as a proxy for social appreciation and assigns reopening times based on flood depth. It also describes recovery dynamics, calculates risk, and identifies mitigation actions to enhance resilience. By accelerating reopening and reinforcing the city's attractiveness, resilience can be significantly improved.
