Relative Coastal Vulnerability for Point Reyes National Seashore. The colored shoreline represents the relative coastal vulnerability index (CVI) determined from six variables. The very high vulnerability shoreline is located along sandy beaches where significant wave heights are highest and regional coastal slope is shallow. The lower vulnerability shoreline is located along rock cliffs where wave heights are lower and coastal slope is steep.

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 rises; and 2) as a planning tool for Point Reyes National Seashore.
