Coastal Changes and Impacts

Hurricane Sandy Region

Topobathymetric Elevation Model of Chesapeake Bay

Hurricane Sandy had significant impacts throughout the Chesapeake Bay, altering the topography and ecosystems of this populous coastal region. In response to the storm, the U.S. Geological Survey (USGS) Coastal and Marine Geology Program in collaboration with USGS National Geospatial Program, and National Oceanic and Atmospheric Administration developed three-dimensional (3D) topobathymetric elevation models for the Chesapeake Bay area.

Chesapeake Bay, the largest estuary in the contiguous United States, lies inland from the Atlantic Ocean, and is surrounded by Maryland and Virginia. Numerous major rivers and streams, such as the Susquehanna and Potomac Rivers, drain through the Washington, D.C. and Baltimore megalopolis into the Chesapeake Bay.
