About this dataset
NOAA's sea level rise inundation mapping showing projected coastal flooding at various sea level rise scenarios (1-10 feet).
The NOAA Sea Level Rise Inundation dataset provides mapping of projected coastal flooding under various sea level rise scenarios ranging from 1 to 10 feet above mean higher high water (MHHW). It covers coastal areas of the United States and territories, supporting climate adaptation planning, flood risk assessment, and coastal resilience studies.
How to download
- 1 Open the NOAA Sea Level Rise data page.
- 2 Select your state or coastal region.
- 3 Choose the sea level rise scenario (1-10 feet) and download the data.
- 4 Open the inundation layers in GeoDataViewer or QGIS for analysis.
FAQ
What sea level rise scenarios are available?
The dataset provides inundation mapping for scenarios of 1, 2, 3, 4, 5, 6, and 10 feet above mean higher high water (MHHW), covering a range of projected timelines.
Does this account for storm surge?
No, the NOAA Sea Level Rise dataset models only static sea level rise inundation. Storm surge and wave effects are modeled separately in other NOAA products.
