Description:

Abstract:

The National Assessment of Coastal Change Hazards project at the U.S. Geological Survey (USGS) exists to understand and predict storm impacts to our nation's coastlines. This geospatial dataset defines the alongshore extent of overwash sediments deposited along the Louisiana coast and attributed to coastal processes during [Atlantic Basin] Hurricane Delta, which made landfall in the U.S. on October 9, 2020.

Purpose:

To provide alongshore extents of overwash deposits caused by Hurricane Delta.

Data_Quality_Information:

Logical_Consistency_Report:

Data were reviewed for quality analysis/quality control (QA/QC'd) by an independent researcher using NOAA photography.

Completeness_Report:

This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

No formal horizontal positional accuracy tests were conducted. Geographic coordinates were projected to the North American Datum of 1983 (NAD 83) Universal Transverse Mercator Zone 15 North (UTM 15N) coordinate system.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

No formal positional vertical accuracy tests were conducted. Data was not projected or referenced to a vertical coordinate system.

Process_Step:

Process_Description:

Overwash extents were manually delineated, using editing tools in ArcMap (10.7.1) by comparing the coastline in Louisiana with pre-storm and post-storm imagery. In order to determine whether overwash had occurred in the study area, USGS staff searched for new sand deposits over roads, marshes and vegetation using methods in Birchler and others (2019).

Source_Used_Citation_Abbreviation: NOAA pre-storm
Source_Used_Citation_Abbreviation: NOAA post-storm
Process_Date: 20201016

Process_Step:

Process_Description:

Overwash extents were QA/QC'd by an independent, second researcher at the USGS using NOAA photography to determine if any features were erroneously identified as overwash but were actually dune erosion (Birchler and others, 2019). The final dataset is a polyline shapefile (.shp) that represent the overwash extent from Hurricane Delta in October 2020.

Process_Description:

The final overwash extent shapefile was converted to a Zipped Keyhole Markup Language (.kmz) file using tools in Global Mapper 21.1 for use with non-proprietary software.
