Abstract
A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise within Gateway National Recreation Area in New York and New Jersey. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of relative sea-level rise, historical shoreline change rates, mean tidal range, and mean significant wave height. The rankings for each variable were combined and an index value was calculated for 1-minute grid cells covering the park. The CVI highlights those regions where the physical effects of sea-level rise might be the greatest. This approach combines the coastal system's susceptibility to change with its natural ability to adapt to changing environmental conditions, yielding a quantitative, although relative, measure of the park's natural vulnerability to the effects of sea-level rise. The CVI provides an objective technique for evaluation and long-term planning by scientists and park managers. Gateway National Recreation Area consists of stable and washover dominated segments of Holocene barrier spit on Breezy Point and Sandy Hook, and Pleistocene glacial outwash and historic artificial fill on Staten Island. The areas within Gateway that are likely to be most vulnerable to sea-level rise are those with the highest occurrence of overwash and the highest rates of shoreline change.
