Relative Coastal Vulnerability for Padre Island 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 located in washover or low dune areas where rates of shoreline erosion are highest. The low vulnerability shoreline is located in the central part of the island where dune ridges are high and continuous and shoreline accretion occurs.

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 Padre Island National Seashore.
