Description:

Abstract:

During Hurricane Irma, Florida and Georgia experienced substantial impacts to beaches, dunes, barrier islands, and coral reefs. Extensive erosion and coral losses from hurricanes result in increased vulnerability of coastal regions, including densely populated areas. Erosion may put critical infrastructure at risk of future flooding and may cause economic loss. The U.S. Geological Survey (USGS) Coastal and Marine Hazards Resources Program is working to assess shoreline erosion along the southeast U.S. coastline and analyze its implications for future vulnerability.

Purpose:

Shoreline positions were collected prior to and following Hurricane Irma along the sandy shorelines of Florida and Georgia. Shoreline positions from the mid-1800s through 2018 were used to update the shoreline change rates for Florida and Georgia using the Digital Shoreline Analysis System (DSAS) software. The shoreline positions and updated shoreline change rates calculated by the USGS provide actionable information to homeowners, coastal communities, and managers of public and private properties. This information can be used to improve resilience to erosion hazards. This information can now also be used by DSAS to estimate the future shoreline position. The forecasted shoreline position for the year 2031, and its estimated uncertainty, are provided in this data release. This forecast should be treated with extreme caution. The method used by DSAS to produce it is still preliminary. Initial testing of the method has shown that forecasts can be highly inaccurate, especially in dynamic areas (for example, near inlets). The degree of error in the forecasted shoreline position may be larger than the estimated uncertainty.

Use_Constraints:

These data were automatically generated using the DSAS version 5 software application and should only be used for purposes explicitly stated by the originating organization. The method used to calculate these forecasts is still being tested for accuracy. These forecasts should be handled with extreme caution and are likely inaccurate in many areas, especially near inlets. Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey as the originator of the dataset.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The attributes are based on the outputs of the Digital Shoreline Analysis System (DSAS) software. Please refer to the cross reference for a full citation. The method used by DSAS to produce these forecasts is still being tested. Initial testing has shown that these forecasts can be highly inaccurate, especially near inlets. The actual error in these shoreline positions may be larger than the estimated uncertainty.

Logical_Consistency_Report:

These data were generated using DSAS, an automated software program which does not perform checks for fidelity of the input features. Any testing on these data should be carried out by end-users to ensure fidelity of relationships.

Completeness_Report:

This dataset contains: (1) polyline shoreline for the year 2031 (10-year forecasts) and (2) the uncertainty range as polygons associated with this shoreline for the coasts of Georgia and Florida. Both the shoreline and uncertainty polygons were generated by the beta Shoreline Forecasting tool in the DSAS v5 software application.

Source_Contribution:

Shoreline change data from Florida and Georgia, including shoreline intersects and rates of shoreline change (linear regression) for dates 1851 - 2018 were used with DSAS to calculate the 10-year shoreline forecasts and associated uncertainty ranges for Georgia and Florida. Shoreline dates vary alongshore. The range given is for all shoreline data in Georgia and Florida.

Process_Step:

Process_Description:

Shoreline change rate data (including rate transects and intersects) from Kratzmann and others (2021) were used with the beta forecasting function in DSAS to produce 10-year shoreline forecasts and the uncertainty range associated with the forecasts. For more information about how the forecast is calculated, see section 8 (“Beta Shoreline Forecasting“) of the DSAS version 5 User Guide listed in the cross references of this metadata file.

Process_Description:

The output forecast files (including forecast and forecast_uncy) were converted from WGS_1984_UTM_Zone_18N (for files with prefix GA, FLec and FLwc)/ WGS_1984_UTM_Zone_17N (FLph), to GCS_WGS_1984 using the ArcToolbox tool “Project” (ArcToolbox > Data Management > Projections and Transformations > Project). Output files were given the same name as the inputs, with "_WGS" as the suffix.
