This geospatial dataset defines the alongshore extent of overwash sediments deposited along the coast of Florida and attributed to coastal processes during [Atlantic Basin] Hurricane Ian, which made landfall in the U.S. on September 28, 2022. Overwash extents are used to validate and improve forecasts of coastal change. See Birchler and others (2019) and Gorski and others (2024) for examples of the application of overwash extents to forecast validation. Purpose: To provide alongshore extents of overwash deposits caused by Hurricane Ian.

Process_Step: Process_Description: Overwash extents were manually delineated, using editing tools in ArcMap (10.8) by comparing the coastline in Florida with pre-storm and post-storm imagery from NOAA. 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: 20230404 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 Ian in September 2022.
