Implementing the European “Floods Directive”: the Case of the Po River Basin

The European “Floods Directive” 2007/60/EC (FD) asks Member States to develop flood risk maps on the bases of most appropriate and advanced tools, with particular attention on limiting required economic efforts. The question arises on how these tools should be selected so as to supply all the knowledge that is required to develop Flood Risk Management Plans (FRMPs). By analysing the implementation of the FD in the Po River Basin (Italy), the paper describes and compares two different approaches for flood risk assessment: the expert driven-qualitative approach vs. the quantitative approach based on damage models. The comparison shows, as expected, that quantitative approaches supply more useful knowledge for the development of FRMPs (and for flood risk management in general) with respect to qualitative approaches. However, they still present limits which prevent their adoption without critically consider the peculiarities of the investigated area in terms of available knowledge on hazard, exposure and vulnerability. Accordingly, considerations are supplied on how effectiveness of quantitative approaches can be maximized, towards flood risk management objectives.
