Coastal Elevation Data and Mapping
Coastal Elevation Data and Mapping
The USGS develops enhanced topographic (land elevation) and bathymetric (water depth) datasets for monitoring and forecasting coastal changes and evaluating impacts from hurricanes due to storm surge, coastal inundation and flooding. These elevation data and maps are critical for assessing risk, decision making and other research and Earth science applications.

Digital Shoreline Analysis System (DSAS)
Computer Software for Calculating Shoreline Change (or positional change of a boundary over time) The Digital Shoreline Analysis System (DSAS) v5 software is an add-in to Esri ArcGIS desktop (10.4-10.7+) that enables a user to calculate rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing measurement locations, performs rate...
COAWST: A Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System
Understanding the processes responsible for coastal change is important for managing both our natural and economic coastal resources. Storms are one of the primary driving forces causing coastal change from a coupling of wave- and wind-driven flows. To better understand storm impacts and their effects on our coastlines, there is an international need to better predict storm paths and intensities...
Interagency Flood Risk Management (InFRM)
In 2014, the Federal Emergency Management Agency (FEMA) began sponsorship of the InFRM team initiative to allow Federal teams across the States of Texas, Oklahoma, New Mexico, Louisiana and Arkansas to better align and integrate. Currently, the InFRM team is comprised of FEMA, US Army Corps of Engineers, US Geological Survey, and the National Weather Service. Information about the Interagency...
Coastal Monitoring Tide Gage Sites in Maryland, Delaware, and Washington, D.C.
Vital coastal storm-tide information needed to help guide storm response efforts following major storms affecting Maryland will be more accessible than ever due to a new monitoring network the U.S. Geological Survey is currently building. A team from the USGS MD-DE-DC Water Science Center is surveying 63 locations in the state, determining their elevations and installing receiving brackets at...
