Relative Coastal Vulnerability for Cape Cod National Seashore. The innermost color bar is the relative coastal vulnerability index (CVI). The remaining color bars are separated into the geologic variables (1-3) and physical process variables (4 - 6). The very high vulnerability shoreline is along Nauset Spit on the elbow of the Cape. High vulnerability shoreline is concentrated mostly within Cape Cod Bay. Moderate vulnerability shoreline is along the Provincetown Spit Complex, and the low vulnerability portion of the shore lies along the outer coast from Head of the Meadow Beach to Marconi Beach.

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 example of where physical changes are most likely to occur as sea-level rises; and 2) as a planning tool for Cape Cod National Seashore.
