Storm-Related Barrier Island Morphological Evolution
Storms quickly and dramatically alter barrier island environments by changing adjacent seafloor morphology, eroding beaches, scarping or leveling dunes, and sometimes creating new inlets. Measuring the magnitude of barrier island sediment movement during and after storms allows us to track rates of beach recovery, dune growth, and inlet-related alterations to barrier island sediment supply.
Barrier Island Sensitivity to Changes in Sediment Supply
Observations and models show that maintaining barrier islands requires a balance between sea-level rise and sediment supply. However, most estimates of sediment supply are not based on modern conditions, which could result in less accurate predictions of sediment fluxes. We explore how natural and human alterations impact modern sediment fluxes, or changes, on barrier islands – research that has...
Shoreface Morphology and Geology
Exchanges of sediment between the shoreface and barrier islands allow barrier islands to adjust to changes in water level, such as those associated with storms or sea-level rise. Characterizing shoreface morphology and geology allows us to explore how past and present processes have impacted modern barrier island sediment transport and what that means for future barrier island evolution.
Modeling Barrier Island Evolution, Shoreface Morphology, and Overwash
Barrier island field observations provide information about past and current environmental conditions and changes over time; however, they can’t tell us about the future. Models can predict possible future behaviors but are only as good as their input data. By integrating both observations and models, we can extend observations and arrive at more realistic predictions of barrier island behavior...
Coastal Sediment Availability and Flux (CSAF) Capabilities
As part of the Coastal Sediment Availability and Flux project, we use innovative technology and integrate a variety of techniques to characterize barrier island environments, reconstruct their past history, and predict their future vulnerability.
Coastal Sediment Availability and Flux (CSAF)
Sediments are the foundation of coastal systems, including barrier islands. Their behavior is driven by not only sediment availability, but also sediment exchanges between barrier island environments. We collect geophysical, remote sensing, and sediment data to estimate these parameters, which are integrated with models to improve prediction of coastal response to extreme storms and sea-level rise...

Scientists walk beside an eroding bluff on the beach
Scientists walk on the beach beside a boardwalk that sits on an eroding bluff at the Rockaway Peninsula, New York. A new study investigates the geologic framework and how human modifications to the coast have influenced sediment availability on this margin.
