Shoreline evolution analysis - Shoreline evolution from 1976/78 to 1982

Analysis of the evolution of the shoreline from 1976/78 to 1982 carried out using the digitized shorelines starting from the orthophotoplans of the RER Flight (Emilia-Romagna Region) of 1976/78 and of the Costa Flight of the Emilia-Romagna Region of 1982. The analysis was performed using an extension of ArcView 3.2 called Digital Shoreline Analysis System (DSAS) developed by the U.S. Geological Survey (USGS). This extension allows you to define a landward baseline, generate equidistant orthogonal transects and calculate rates of change. For each transect, the variation of the shoreline (positive = progress; negative = erosion), the progress-erosion rate (metres/year) and various statistical parameters are then calculated.

lineage The shoreline evolution measurements were performed using the shorelines digitized on the RER Flight of 1976/78 and on the Costa Flight of 1982. A ground baseline was created from which orthogonal transects were generated with equidistance of 20 meters, for each transect the variations in meters have been extracted starting from the oldest shoreline to the most recent one, therefore positive values ​​indicate progress, while negative values ​​indicate erosion of the coast. On the basis of the time elapsed between one aerial shot and the next, the "Rate of variation" of the shoreline expressed in metres/year was calculated for each transect. Also in this case, positive values ​​indicate progress, negative values ​​indicate erosion.
