CHIS: coastal vulnerability - The calculated coastal vulnerability index for the Channel Islands National Park expresses the relative vulnerability of the coast to physical changes due to future sea-level rise. This method yields numerical data that cannot be equated directly with particular physical effects. It does, however, highlight areas where the various effects of sea-level rise may be the greatest.
