From: Improvement of a coastal vulnerability index and its application along the Calabria Coastline, Italy
Type of variables | # | Variables | Remarks |
|---|---|---|---|
Geologic | 1 | Geomorphology | Proposed by4 and already considered in the previous authors’ CVI27 |
2 | Coastal slope (%) | Proposed by4 and already considered in the previous authors’ CVI27 | |
3 | Shoreline erosion/accretion rates (m/year) | Proposed by4 and already considered in the previous authors’ CVI27 | |
4 | Emerged beach width (m) | Already considered in the previous authors’ CVI27 | |
5 | Dune | Redefined considering the dune width, already used in the previous authors’ CVI27, and the type of dune | |
Hydro-physical process | 6 | River discharge (m3/s) | New variable added in the present work |
7 | Relative sea-level change (mm/year) | Proposed by4 and already considered in the previous authors’ CVI27 | |

Vegetation | 10 | Vegetation behind the back-beach | Redefined considering the width of vegetation behind the beach, already used in the previous authors’ CVI27, and the type of vegetation |
11 | Coverage of Posidonia oceanica (%) | Redefined considering not only its presence/absence but also the bottom coverage of meadows |
