Abstract

Following the European Council Floods Directive (2007/60/EC) and the Italian National Legislation (DL n. 49/2010), the Sardinian (Italy) Hydrographic District Authority defined the main directives on the assessment and management of flood risk in related basins. This planning phase is subsequent of a detailed flood risk mapping and consequent identification of flood prone areas. Recent historical events highlighted on this necessity as the Sardinia region was affected by important floods, typical of the Mediterranean area. In December 2004 the territory of Eastern Sardinia was the scenario of a massive flood event characterised by 500 mm rainfall in five hours. In October 2008 a storm hit the South-Eastern territory and 350 mm of rain was gauged in less than 3 hours. More recently, in November 2013 the Cleopatra hurricane affected the North East of Sardinia causing huge damage. Following these emergencies and legislation directives, the Sardinian Hydrographic Authority is working on flood risk management plans involving researchers, communities and stakeholders. In this paper we focused on a framework plan to describe the assessment of flood risk management plans and consider some pilot areas to define a decision support tool with priorities in flood mitigation measures. Preliminary results are illustrated for these pilot areas observing different mitigation options (structural and non-structural).
