National Assessment of Coastal Vulnerability to Sea Level Rise

Science Center Objects

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the National Assessment of Coastal Change Hazards project.

The objectives of the national CVI assessment are to highlight areas where coastal change as a result of coastal hazards and exposure may be most likely to occur in the coming decade, and to provide a quantitative tool to assist in managing resources. Coastal hazards include erosion, storms, flooding, and SLR. Coastal Exposure is characterized by flood frequency, tidal regime, landcover, and waves. Please check back for updated CVI products.

Following the completion of the national CVI assessment in 2001, the USGS partnered with the National Park Service (NPS) to conduct higher resolution, park specific CVI assessments within 22 coastal park units. For more information on the NPS-CVI study visit:
