Abstract: Cultural heritage is one of the most complex elements to analyze in terms of flood risk. This complexity arises from several factors. First, cultural heritage sites often have unique construction characteristics that can locally influence both flood hazard and exposure. Second, the expected impacts of floods are difficult to generalize using the vulnerability curves typically applied to other types of buildings. Third, the value at risk extends far beyond the monetizable costs of restoration or rehabilitation; it encompasses numerous intangible aspects, including aesthetic, spiritual, historical, and cultural values. Flood risk assessment for cultural heritage has predominantly been conducted at broad national or regional spatial scales. The objective of this work is to propose a methodological framework for integrated flood risk assessment of cultural heritage assets at an intermediate scale, such as historic centers or UNESCO sites. This framework seeks to balance three key components: (1) simulated flood hazard, (2) information obtained through field surveys, and (3) insights from participatory approaches. The proposed methodology is designed to support management plans for UNESCO sites, with a primary focus on preserving and enhancing cultural heritage. To illustrate this approach, the study focuses on the area within the UNESCO-designated perimeter of the city of Florence, Italy.
