I am current involved in 4 primary research and applied projects. These projects all focus on understanding, predicting, and assessing aspects of coastal change and the interaction of these changes with natural or human systems. The projects differ in the focal time scale, which ranges from climate-change time scales (100s to 1000s of years) to event time scales (hours to days). And the projects differ in the balance between fundamental and applied research leading to assessments of coastal vulnerabilities that impact coastal management. My approach is to use applications (e.g., oil spill, hurricane, and endangered species response) to focus fundamental research on objectives that will have intrinsic scientific value as well as societal impact. The common thread for my research efforts are (1) coupling of the interacting physical, biological, and societal systems models, (2) development of these models and increasing their skill and accuracy, and (3) evaluating model-based hypotheses with robust and powerful statistical methods.
Science and Products
The Sea Level Rise Hazards and Decision Support project assesses the potential impacts of sea level rise and provides tools for coastal management decision making. Historical and recent observations of coastal change are combined with model simulations of coastal environments such as barrier islands, wetlands, and coastal aquifers. A variety of methods including Bayesian...
This project integrated a wetland assessment with existing coastal-change hazard assessments for the adjacent dunes and beaches of Assateague Island, Maryland, to create a more comprehensive coastal vulnerability assessment.
We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.
The overall objective is to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety. Research is part of the National Assessment of Coastal Change Hazards project.
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
Science for a risky world—A U.S. Geological Survey plan for risk research and applications
Executive SummaryNatural hazards—including earthquakes, tsunamis, volcanic eruptions, landslides, hurricanes, droughts, floods, wildfires, geomagnetic storms, and pandemics—can wreak havoc on human communities, the economy, and natural resources for years following an initial event. Hazards can claim lives and cause billions of dollars in damage...Ludwig, Kristin A.; Ramsey, David W.; Wood, Nathan J.; Pennaz, Alice B.; Godt, Jonathan W.; Plant, Nathaniel G.; Luco, Nicolas; Koenig, Todd A.; Hudnut, Kenneth W.; Davis, Donyelle K.; Bright, Patricia R.
Dynamic modeling of barrier island response to hurricane storm surge under future sea level rise
Sea level rise (SLR) has the potential to exacerbate the impacts of extreme storm events on the coastal landscape. This study examines the coupled interactions of SLR on storm-driven hydrodynamics and barrier island morphology. A numerical model is used to simulate the hydrodynamic and morphodynamic impacts of two Gulf of Mexico hurricanes under...Passeri, Davina L.; Bilskie, Matthew V.; Plant, Nathaniel G.; Long, Joseph W.; Hagen, Scott C.
A framework for modeling scenario-based barrier island storm impacts
Methods for investigating the vulnerability of existing or proposed coastal features to storm impacts often rely on simplified parametric models or one-dimensional process-based modeling studies that focus on changes to a profile across a dune or barrier island. These simple studies tend to neglect the impacts to curvilinear or alongshore varying...Mickey, Rangley; Long, Joseph W.; Dalyander, P. Soupy; Plant, Nathaniel G.; Thompson, David M.
Barrier-island and estuarine-wetland physical-change assessment after Hurricane Sandy
IntroductionThe Nation’s eastern coast is fringed by beaches, dunes, barrier islands, wetlands, and bluffs. These natural coastal barriers provide critical benefits and services, and can mitigate the impact of storms, erosion, and sea-level rise on our coastal communities. Waves and storm surge resulting from Hurricane Sandy, which made landfall...Plant, Nathaniel G.; Smith, Kathryn E.L.; Passeri, Davina L.; Smith, Christopher G.; Bernier, Julie C.
The influence of bed friction variability due to land cover on storm-driven barrier island morphodynamics
Variations in bed friction due to land cover type have the potential to influence morphologic change during storm events; the importance of these variations can be studied through numerical simulation and experimentation at locations with sufficient observational data to initialize realistic scenarios, evaluate model accuracy and guide...Passeri, Davina L.; Long, Joseph W.; Plant, Nathaniel G.; Bilskie, Matthew V.; Hagen, Scott C.
Smartphone technologies and Bayesian networks to assess shorebird habitat selection
Understanding patterns of habitat selection across a species’ geographic distribution can be critical for adequately managing populations and planning for habitat loss and related threats. However, studies of habitat selection can be time consuming and expensive over broad spatial scales, and a lack of standardized monitoring targets or methods...Zeigler, Sara; Thieler, E. Robert; Gutierrez, Ben; Plant, Nathaniel G.; Hines, Megan K.; Fraser, James D.; Catlin, Daniel H.; Karpanty, Sarah M.
Examples of storm impacts on barrier islands: Chapter 4
This chapter focuses on the morphologic variability of barrier islands and on the differences in storm response. It describes different types of barrier island response to individual storms, as well as the integrated response of barrier islands to many storms. The chapter considers case study on the Chandeleur Island chain, where a decadal time...Plant, Nathaniel G.; Doran, Kara S.; Stockdon, Hilary F.
Coastal Topography—Assateague Island, Maryland and Virginia, Post-Hurricane Hermine, 10–12 September 2016

Correction of elevation offsets in multiple co-located lidar datasets
IntroductionTopographic elevation data collected with airborne light detection and ranging (lidar) can be used to analyze short- and long-term changes to beach and dune systems. Analysis of multiple lidar datasets at Dauphin Island, Alabama, revealed systematic, island-wide elevation differences on the order of 10s of centimeters (cm) that were...Thompson, David M.; Dalyander, P.
