Abstract

In the last century the number of floods affecting people increased across Europe, due to both more frequent intense events and the growth of population and urbanization in flood-prone areas. Equipping cities with tools for flood damage assessment is crucial to effectively manage and reduce flood risk. The sector of businesses has a key role in cities development and suffers high losses in case of inundation, but damage appraisal to economic activities is still a challenging task. This study took up the challenge of addressing this topic, with specific reference to direct damage and the Italian context. Two approaches have been implemented: the analysis of about a thousand damage data regarding economic activities in four Italian flood events and the development of damage functions for retail activities by means a synthetic approach. The results led to the identification of the most vulnerable elements of different types of economic activities and provided reference values to assess the order of magnitude of flood damage.
