Coastal Change

Coastal change poses potential risk to coastal communities across the nation. Powerful storms generate surge, waves, and currents that can move large amounts of sediment; can destroy roads, buildings, and other critical infrastructure; and can alter natural habitats. The USGS performs a range of studies that document, assess, and model coastal change, risk, and vulnerability. These studies include historical shoreline change and the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

The Florida Coastal Mapping Program

The Florida Coastal Mapping Program (FCMaP) is an initiative between Federal and Florida State agencies and institutions to coordinate and facilitate the collection and accessibility of Florida coastal seafloor data in order to fill priority areas and gaps.

Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...

Hurricane Sandy Response - Storm Impacts and Vulnerability of Coastal Beaches

Scientists evaluated and improved the accuracy of pre-landfall forecasts of storm-induced coastal erosion hazards for Northeast beaches using data from post-Sandy lidar sruveys, beach morphology, and storm hydrodamics.

National Assessment of Storm-Induced Coastal Change Hazards

This project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. The overall objective is to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety.

Integrating Mapping and Modeling to Support the Restoration of Bird Nesting Habitat at Breton Island National Wildlife Refuge

In response to storms, reduced sediment supply, and sea-level rise, Breton Island is rapidly deteriorating, impacting the available nesting habitat of endangered seabirds. This study provides critical information regarding the physical environment of the island system. Research is part of the ...

Science Support for the Mississippi Coastal Improvement Project

Since 2007, the USGS (with NPS and USACE) has been mapping the seafloor and substrate around the Mississippi barrier islands to characterize the near-surface stratigraphy and identify the influence it has on island evolution and fate. Research is part of the Geologic and Morphologic...

Video Remote Sensing of Coastal Processes

Video observations of the coast are used to monitor a range of coastal processes, for example changes in the shoreline position, both seasonally and due to long-term effects such as sea-level rise, and instances of beach and dune erosion during extreme storm events.
