Conclusions

The coastal vulnerability index (CVI) provides insight into the relative potential of coastal change due to future sea-level rise. The maps and data presented here can be viewed in at least two ways:

1) as an indication of where physical changes are most likely to occur as sea level continues to rise; and

2) as a planning tool for the GGNRA.

As ranked in this study, geomorphology, regional coastal slope, and mean significant wave height play the largest role in determining the spatial variability of the CVI for GGNRA. Shoreline change, relative sea-level rise, and tidal range vary less spatially.

GGNRA preserves a dynamic natural environment, which must be understood in order to be managed properly. The CVI is one way that park managers can assess objectively the natural factors that contribute to the evolution of the coastal zone, and thus how the park may evolve in the future.
