Summary: | Methodologies to estimate economic flood damages are increasingly important
for flood risk assessment and management. In this work, we present a new
synthetic flood damage model based on a component-by-component analysis of
physical damage to buildings. The damage functions are designed using an
expert-based approach with the support of existing scientific and technical
literature, loss adjustment studies, and damage surveys carried out for past
flood events in Italy. The model structure is designed to be transparent and
flexible, and therefore it can be applied in different geographical contexts
and adapted to the actual knowledge of hazard and vulnerability variables.<br><br>
The model has been tested in a recent flood event in northern Italy.
Validation results provided good estimates of post-event damages, with
similar or superior performances when compared with other damage models
available in the literature. In addition, a local sensitivity analysis was
performed in order to identify the hazard variables that have more influence
on damage assessment results.</p> |
