This work investigates the integration between a detailed hydraulic model and transport models to create risk maps for pedestrians and drivers. These maps support Civil Protection operations and training, and ultimately improving flood preparedness.
Article
Full-text available
The potential spread of pollutants stored in environmental hotspots such as wastewater treatment plants, waste handling facilities, contaminated sites, etc., is among the adverse consequences of floods. This aspect has been rarely examined with a risk-based approach, although required by the European legislation. In this study, a method for estimat...
Article
Full-text available
Flood risk mitigation usually requires a significant investment of public resources and cost-effectiveness should be ensured. The assessment of the benefits of hydraulic works requires the quantification of (i) flood risk in absence of measures, (ii) risk in presence of mitigation works, (iii) investments to achieve acceptable residual risk. In thi...
