FloodRisk: a collaborative, free and open-source software for flood risk analysis

Viene presentata una panoramica dello stato attuale dello sviluppo di un plugin per QGIS chiamato “Floodrisk”. L’articolo comprende una descrizione dell’architettura informatica ed un esempio di applicazione e di rappresentazione dei risultati.

The European “Floods Directive” 2007/60/EC focuses on the develop of flood risk maps and management plans on the basis of the most appropriate and advanced tools. This pushed a paradigm shift for moving to sustainable development through processes of stakeholder engagement to improve the efficiency and transparency of decision processes. In this context, this research project developed a free and open-source GIS software, called FloodRisk, to operatively support stakeholders in their compliance with the risk maps delineation and the management of current and future flood risk based on their needs for multi-purpose applications.

In this paper, a high resolution impact assessment framework based on 2D inundation modelling with different return periods was used, as input, within the FloodRisk model to reconstruct the socio-economic damages based on a case study showing how structural and non-structural measures can significantly decrease the cost of floods for households. The sensitivity of the FloodRisk model was also examined and it was found to be highly dependent on the selection of damage functions and the economic values of the exposed assets.
