Relative Coastal Vulnerability for Olympic National Park. 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 generally located along sandy and gravel beaches where regional coastal slope is low. High vulnerability shoreline is concentrated north of Mora. Moderate vulnerability and low vulnerability coastline is mostly south of Mora.

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 Olympic National Park.
