Number of ‘rigid’ coastline defence works

The synthesis work was as follows:1. Demarcation of the beaches on the basis of the aerophotogrammetric flights in our possession 2. Verification and updating of port works along the coastlines (breaking barriers, brushes, soffolted dams, dams), also on the basis of flights:a. From Eraclea to the mouth of the Tagliamento (year 2009, flight MAV)b. From Isola Verde to the mouth of Piave (year 2012, flight MAV)c. From Green Island to the delta of the Po (year 2006-2007, flight ITA2006)Calculum for sand coast of the number of barrier breaks, brushes and dams (offl and dams)3. Demarcation of the portion of beaches directly close to the various harbour works: calculation of the percentages of ‘rigid’ and ‘soft’ defence beaches 4. Ampiezza:per the assessment of the size of the beaches (because of the non-homogeneous forms), were arranged lines of measures transversal to the development of the beaches, Calculate the various widths and per beach determined (in meters) the minimum, average and maximum values found.5. Calculation in ha of the overall surface area of each beach and calculation (in metres) of the longitudinal development of the beach.6. Inserting ISTAT code and name of the municipality to which it belongs
