The U.S. Geological Survey's Coastal Change Hazards Portal provides an interactive map showing the hazards posed to U.S. coasts from extreme storms, shoreline change, and sea-level rise. The map includes:
- Probabilities of collision, overwash, and inundation from nor'easters (Atlantic coast) and hurricanes (Atlantic and Gulf coasts) of different intensities, with predicted water levels and shoreline erosion effects.
- Beach morphologies on the Atlantic and Gulf Coasts
- Historical shoreline positions for the entire coastal United States
- Shoreline change forecasts due to long-term sea-level rise
- Coastal vulnerability due to sea-level rise on Atlantic, Gulf, and Pacific coasts
- Detailed coastal hazard forecasts and histories for selected current or recent hurricanes, tropical, and extratropical storms
Users can download datasets for further use and analysis.
