Description:

Abstract:

The National Assessment of Coastal Change Hazards project derives beach morphology features from lidar elevation data for the purpose of understanding and predicting storm impacts to our nation's coastlines. This dataset defines mean beach slopes along the United States Southeast Atlantic Ocean from Miami to Jupiter, Florida for data collected at various times between 1999 and 2009.

Purpose:

To provide mean slope data between the endpoint locations of the Mean High Water and seaward-most dune toe elevations, interpolated to a 200 meter alongshore resolution using a 400-meter wide Hanning window. This dataset, SFL_Mean_Slopes.txt, and others associated with this project can be accessed online at https://doi.org/10.5066/F72805P1.

Data_Quality_Information:

Logical_Consistency_Report:

Data gaps exist where there are no sandy shorelines (such as over inlets, marshes, or rocky coasts). For each 400 meter window width, data will be given a null value if greater than 50% of points are missing. For inlets narrower than the 400-m window, only slopes associated with the data on either side of the inlet were computed. No additional checks for consistency were performed on this data.

Completeness_Report:

These data include beach and dune morphology in the form of mean beach slopes.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: Horizontal accuracy was not estimated.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Vertical accuracy for beach and dune morphology (dune crest and toe elevation) data is dependent on the positional accuracy of the lidar data. Estimated accuracy of lidar surveys is +/- 15 centimeters. However, vertical accuracies may vary based on the type of terrain (for example, inaccuracies may increase as slope increases or with the presence of extremely dense vegetation) and the accuracy of the GPS and aircraft-attitude measurements.

Process_Step:

Process_Description:

For dune morphology data: Elevation data from lidar surveys were interpolated in MATLAB R2014b to a gridded domain that was rotated parallel to the shoreline and had a resolution of 10 m in the alongshore direction and 2.5 m in the cross-shore direction. The interpolation method applies spatial filtering with a Hanning window that is twice as wide as the grid resolution. Dune morphology data are extracted from the elevation grid in MATLAB. Beach slopes were extracted from endpoint locations of the Mean High Water and dune toe elevations. The beach slopes were temporally averaged then interpolated to 200 m alongshore resolution by filtering with a 400 m wide Hanning window. More details on the methodology can be found in the USGS Open-File Report, "A method for determining average beach slope and beach slope variability for U.S. sandy coastlines", available at http://pubs.usgs.gov/of/2015/1053
