VULNERABILITY ANALYSIS OF LAZIO REGION COASTS FOR AN INTEGRATED PROTECTION PLAN

Medium-term planning of coastal protection at a regional scale is essential for a sustainable expenditure of public resources. In 2020-22 the Land Defense Department of the Lazio Region appointed the Coastal Engineering Group of Roma TRE University to perform a comprehensive set of studies to support such a Coastal Plan and provide a Priority List of interventions on the regional shoreline to be funded to the 22 coastal municipalities within the 3-year programme. The 300 km coastline (60 km of which are inerodible rocky coasts) has been subdivided in 8 main “independent” Physiographic Units and in shorter secondary cells with a discretization of 815 transects of 300 m length. The work was divided in 3 phases: 1) organization of existing datasets; 2) analysis of the present situation; 3) definition of most critical coastal areas and protection strategies and guidelines.
