Data and Tools
Percentage of sandy beaches very likely (probability > 0.9) to experience erosion associated with collision, overwash, and inundation during category 1-5 hurricane landfall.
Total water level (TWL) at the shoreline is the combination of tides, surge, and wave runup. A forecast of TWL is an estimate of the elevation where the ocean will meet the coast and can provide guidance on potential coastal erosion and flooding hazards.
Obique photos offer a unique perspective of the coast. Features such as beach erosion or accretion, dune erosion and overwash can all be clearly characterized in this imagery. It also documents coastal infrastructure, as well as the damage that infrastructure may incur as the result of an impacting hurricane.
The National Water Information System (NWIS) web application provides access to surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.
The National Water Information System (NWIS) Mapper provides access to water-resources data at over 1.5 million sites across the U.S., including current and historical data. Users can search by site type, data type, site number, or place.
Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.
The web map provides geospatial visualization and situational awareness over the current disaster event. In addition to National Map base data and indexes the map can be used as a management and planning resource by providing access to enhanced elevation data availability, NOAA Nexrad weather radar and NOAA NowCoast storm surge and precipitation estimates.
The USGS Flood Event Viewer helps USGS and its partners to track of the storm and its impact on surface water levels. A storm track field is included from NOAA's National Hurricane Center, and real-time USGS streamgage data and Rapid Deployment Gage data are linked through this map-based product.
The USGS Flood Event Viewer (FEV) is the public data discovery component of the Short-Term Network (STN) database. Data viewable and downloadable from this page are from the STN database. This application integrates with the USGS National Water Information System (NWIS) database for display of time-series water data.
Explore critical pre- and post-disaster images and datasets online for immediate viewing and downloading. The U.S. Geological Survey (USGS) Emergency Operations, in support of the Department of Homeland Security, provides these images for use in disaster preparations, rescue and relief operations, damage assessments, and reconstruction efforts.
