Abstract

These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online mapping viewer depicting potential sea level rise and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea level rise (slr) and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may be accessed at: https://www.coast.noaa.gov/slr

These data depict the potential inundation extent of coastal areas resulting from minor high tide flooding, as defined by the NOAA Technical Report NOS CO-OPS 086: Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold. (https://www.tidesandcurrents.noaa.gov/publications/techrpt86_PaP_of_HTFlooding.pdf)

The process used to produce the data uses two source datasets to derive the final inundation rasters: the Digital Elevation Model (DEM) of the area and a water surface that represents minor high tide flooding. The minor high tide flooding water surface is based on the equation defined in the technical report referenced above and tidal datum surfaces derived from NOAA's VDatum model.

The methods used to produce these data does not account for erosion, subsidence, or any future changes in an area's hydrodynamics. It is simply a method to derive data in order to visualize the potential scale and extent, not exact location, of inundation from NWS issued Coastal Flood Advisories.

Distribution Information

No Distributions available.

Access Constraints:

None

Use Constraints:

These data illustrate the scale of potential flooding, not the exact location, and do not account for erosion, subsidence, or future construction. Inundation is shown as it may appear during Coastal Flood Advisory conditions. These data should be used only as a screening-level tool for management decisions. As with all remotely sensed data, all features should be verified with a site visit. The dataset is provided "as is," without warranty to its performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of this dataset is assumed by the user. This dataset should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes.

Data Quality

Completeness Report:

The minor high tide flooding inundation extent areas currently shown in the NOAA Sea Level Rise Viewer. The current status of areas of coverage for the tool can be accessed at: https://coast.noaa.gov/slr.

Conceptual Consistency:

Standard methods for determining inundation were used. The vertical accuracy of these data is dependent on the source elevation data and the error associated with vertical datum conversions within NOAA's VDatum software.

Process Steps

Process Step 1

CC ID: 620434
Description:

The process to derive the inundation rasters is as follows:

1. A water surface is created using NOAA VDATUM outputs and the minor high tide flood threshold equation defined in the NOAA technical report referenced above.

2. Using the DEM and the water surface, raster calculations are made to generate one 8-bit single value raster representing the extent of inundation.
