The present paper presents an integrated model for the ex-ante evaluation of flood damages based on “stage damages curve” as a decision support tool for public and private authorities in the sustainable management of risk areas. The proposed model aims to estimate the damage both at a micro-scale and on an extended area. In particular, the dynamics of flooding in flood areas and their effects on the degree of vulnerability of the different types of buildings are considered. The proposed model, already experimented in different territorial contexts, has been applied to the case of the Senigallia flood, which took place in 2014. The first results show that the approach based on damage curves applied to different types of exposed goods at a micro-scale can reliably estimate the damages to buildings. In contrast, the ex-ante estimation of indirect damages is still uncertain due to the difficulty of evaluating, according to reliable criteria, unique assets such as intangibles and cultural and environmental assets.

Abstract
The present paper presents an integrated model for the ex-ante evaluation of flood damages based on “stage damages curve” as a decision support tool for public and private authorities in the sustainable management of risk areas. The proposed model aims to estimate the damage both at a micro-scale and on an extended area. In particular, the dynamics of flooding in flood areas and their effects on the degree of vulnerability of the different types of buildings are considered. The proposed model, already experimented in different territorial contexts, has been applied to the case of the Senigallia flood, which took place in 2014. The first results show that the approach based on damage curves applied to different types of exposed goods at a micro-scale can reliably estimate the damages to buildings. In contrast, the ex-ante estimation of indirect damages is still uncertain due to the difficulty of evaluating, according to reliable criteria, unique assets such as intangibles and cultural and environmental assets.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
