Short summary
The paper compares two methodologies adopted by the Emilia-Romagna region, northern Italy, to evaluate coastal vulnerability and to produce hazard and risk maps for coastal floods, in the framework of the EU Floods Directive. The flooded area extension is determined by a series of computations, whose core is the Cost Distance tool of ArcGIS®. The qualitative validation and the comparison between the two methods show a positive agreement.
