The USGS Coastal Change Hazards team collects data to monitor coastal change – including how storms and waves shape and reshape our beaches. It’s important to keep track of how beaches change over time because they provide habitat for many creatures including birds and sea turtles, and they are beautiful locations where people love to live and vacation.

This photo is the results of processing a time series of images, which are a combination of all image frames collected during a 10 to 17-minute video. These images are incredibly useful for studying coastal change remotely, but the usefulness of the image depends on how they are processed.

We conduct fieldwork in a variety of barrier island settings to understand the relative importance of these factors, including Fire Island, NY; Rockaway, NY; Seven Mile Island, NJ; and Cedar Island, VA.

As Hurricane Sally approached the US Gulf Coast, the USGS Coastal Change Hazards team produced a series of forecasts for impacts on the beach. Forecasts were updated daily based on wave and storm surge forecasts from NOAA.

The Total Water Level and Coastal Change Forecast has continually expanded since real-time forecasts began in 2015. In 2020, new regions of the Gulf and South Atlantic coasts were added to the forecast and officially approved for use in National Weather Service Forecasts.

This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura. The model accounts for sandy beaches and barrier islands and does not include marshes,

The USGS Remote Sensing Coastal Change Project collected aerial imagery of the northern Outer Banks, North Carolina coastline from pre- and post-Hurricane Isaias, in order to use Structure-from-Motion techniques to produce digital elevation models (DEMs) and orthomosaic photos, to be used in evaluating the storm-induced coastal change, such as sand transported onto

USGS coastal change experts predict that storm waves kicked up by the Category 1 hurricane are likely to cause some erosion at the base of the dunes along about 11 percent of coastal beaches between Florida and Virginia.

Strong storms such as hurricanes can cause drastic changes to coastal environments. For example, this large washover fan was created on Fire Island, New York in 2012 after Hurricane Sandy by waves moving sediment from the dunes and beach towards the back-barrier environment.
