Rachel Elizabeth Henderson
(She/her)I conduct research at USGS within the Coastal and Marine Hazards and Resources Program focused on shoreline change - from data collection to the development of software that measures change.
I am a Physical Scientist at the Woods Hole Coastal and Marine Science Center with the U.S. Geological Survey. I oversee projects that define shorelines and measure shoreline change. I am interested in maintaining foundational shoreline datasets that support more complex models of coastal change. My focus recently has been helping migrate the USGS's Digital Shoreline Analysis System software (an application that calculates shoreline or boundary change over time) to a platform agnostic application that can run without the need for a licensed GIS software, supporting the needs of the global user base for change analysis.

Assateague Island Seabeach Amaranth Survey Data — 2001 to 2018
Seabeach amaranth (Amaranthus pumilus) is a plant species that was once prevalent on beaches of the U.S. mid-Atlantic coast but is now listed as threatened by the U.S. Fish and Wildlife Service. For much of the 20th century, seabeach amaranth was absent from the mid-Atlantic coast and thought to be extinct, presumably as a result of increased development and recreational pressure.

Coastal Change Likelihood in the U.S. Northeast Region: Maine to Virginia
Coastal resources are increasingly impacted by erosion, extreme weather events, sea-level rise, tidal flooding, and other potential hazards related to climate change. These hazards have varying impacts on coastal landscapes due to the numerous geologic, oceanographic, ecological, and socioeconomic factors that exist at a given location. Here, an assessment framework is introduced that synthesizes
Seabeach amaranth presence-absence and barrier island geomorphology metrics as relates to shorebird habitat for Assateague Island National Seashore — 2008, 2010, and 2014
Understanding how sea-level rise will affect coastal landforms and the species and habitats they support is critical for developing approaches that balance the needs of humans and native species. Given the magnitude of the threat posed by sea-level rise, and the urgency to better understand it, there is an increasing need to forecast sea-level rise effects on barrier islands.

Forecasting future beach width- A case study along the Florida Atlantic coast
Historical cross-shore positions of the shoreline and dune base were used as inputs for a Kalman filter algorithm to forecast the positions of these features in the year 2028. The beach width was also computed as the cross-shore distance between the forecasted 2028 shoreline and dune-base positions.

Characterizing storm response and recovery using the beach change envelope: Fire Island, New York
Hurricane Sandy at Fire Island, New York presented unique challenges in the quantification of storm impacts using traditional metrics of coastal change, wherein measured changes (shoreline, dune crest, and volume change) did not fully reflect the substantial changes in sediment redistribution following the storm.
