Costs and consequences of natural hazards can be enormous; each year more people and infrastructure are at risk. We develop and apply hazards science to help protect U.S. safety, security, and economic well being. These scientific observations, analyses, and research are crucial for the Nation to become more resilient to natural hazards.

Estuarine Processes Tidal Wetlands

Tidal wetlands are an important geomorphic and ecological feature of the coastal zone. Our projects deal with the physical forcings that affect wetland stability over event-to-annual timescales, including wave attack, sediment supply, and sea-level rise.

Estuarine Processes Coastal Hazards

Extreme tides and coastal storms transfer high water levels to estuaries through natural and managed entrances. The size of the transfer depends on the duration of the event and the geomorphology of the estuary. We use observational data and modeling scenarios to understand and spatially map this transfer at our study sites.

Biogeomorphic classification and images of shorebird nesting sites on the U.S. Atlantic coast

Atlantic coast piping plover (Charadrius melodus) nest sites are typically found on low-lying beach and dune systems, which respond rapidly to coastal processes like sediment overwash, inlet formation, and island migration that are sensitive to climate-related changes in storminess and the rate of sea-level rise. Data were obtained to understand piping plover habitat distribution.

Conceptual salt marsh units for wetland synthesis: Edwin B. Forsythe National Wildlife Refuge, New Jersey

Recent research shows that sediment budgets of microtidal marsh complexes on the Atlantic and Pacific coasts of the United States consistently scale with areal unvegetated/vegetated marsh ratio (UVVR) despite differences in sea-level rise, tidal range, elevation, vegetation, and stressors. This highlights UVVR as a broadly applicable indicator of microtidal marsh stability.
