Abstract: | This paper presents the initial results of a common methodology for the evaluation of damage produced by a flood. A model
has been developed for flood damage estimation based on a geographic information system (GIS). It could be used by land administration
bodies and insurance companies to manage flood-related damage data. The model simulates flood scenarios and evaluates expected
economic losses from the impact of floodwaters on exposed elements, through the application of a computational model elaborated
by GIS. During the development of the model, the Boesio Stream, a small watercourse flowing into Lake Maggiore (Lombardy,
northern Italy) which was recently affected by a flash flood, was used as case study to test and calibrate the methodology.
The method could be used either as a forecasting tool to define event scenarios, utilizing data from events simulated with
a hydraulic model, or for real-time damage assessment after a disaster. The approach is suitable to large-area damage assessment
and could be appropriate for land use planning, civil protection and risk mitigation.
