Figure 5. Relative Coastal Vulnerability for Assateague 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 low overwashed areas where rates of shoreline erosion are highest. The low vulnerability shoreline is located at the southernmost end of Assateague in Virginia near Chincoteague Inlet where shoreline accretion rates are high.
