WHAT DOES IT INVOLVE?

This investigation analyses the physical vulnerability in the first 100 meters of coastline. This research used geomorphological variables and oceanic data for the CVI index generation. The aim of the study is analyses the possible risks associated to global change in Galicia.

“More than 4% of coastline presents high or very high vulnerability rates.”

FOR KNOW MORE

The Coastal Vulnerability Index (CVI) was generated with the following data: slope, elevation, orientation, type of coast, lithology, change in the mean sea level, mean wave height and the distance to the 20 meters bathymetric line.


The results were divided in 5 levels, being 1 the less vulnerability level. The high or very high vulnerability zones occupy 4.52% of Galician coastline, especially sedimentary areas. Meanwhile, the majority coastline present low vulnerability rates (57.96%).

CURIOSITIES

*

Rodas beach (Cies Islands) is one of the most vulnerable sectors.

These studies are essential to mitigate the global change effects.
