The XBeach model setup requires the input of a merged topographic and bathymetric digital elevation model (DEM), and inputs of wave spectra (based on significant wave height, peak wave period and wave direction) and water level (tide and surge) time series. Model inputs and outputs in the form of topography and bathymetry are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Passeri and others, 2018. These data were generated for the XBeach model to examine the effects of storm surge under sea level rise on barrier island morphology. Ivan_IntLow_SLR.zip is a dataset that consists of Federal Geographic Data Committee (FGDC) metadata and a Network Common Data Form (NetCDF) file containing the following variables: coordinates of the model grid (Easting and Northing) and the final bathymetric/topographic (z) model elevation values, in meters, for the Hurricane Ivan intermediate-low sea level rise scenario. 20180716 publication date complete As needed -88.8654564994 -88.7366845091 30.0633577357 29.7867685543 USGS Metadata Identifier USGS:8a1ef084-3f11-4af0-8e3f-fc47c96f6e7d None U.S. Geological Survey USGS St. Petersburg Coastal and Marine Science Center marine sediment transport SPCMSC barrier island morphologic change digital elevation models sea level rise storm impact Hurricane Ivan Hurricane Katrina estuaries coastal ISO 19115 Topic Category oceans elevation geoscientificInformation USGS Thesaurus marine geology geomorphology topography bathymetry coastal ecosystems estuarine ecosystems tides (oceanic) storm surge digital elevation models sea-level change ocean processes sediment transport Geographic Names Information System (GNIS) Content Gulf of Mexico Alabama North America United States Dauphin Island None.

These are likely a result of the inability of XBeach to accurately calculate flow and sediment transport in areas with complex shorelines that are oriented perpendicular to the offshore boundary as well as in low elevation marshes. For this reason, these areas are not included in the analysis. The resultant DEM from the Hurricane Ivan intermediate-low sea level rise scenario contains topographic and bathymetric elevations at each model grid cell. This DEM contains the complete resultant model grid elevations from the Hurricane Ivan intermediate-low sea level rise scenario. This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. This DEM contains the resultant model topographic and bathymetric elevations from the Hurricane Ivan intermediate-low sea level rise simulation. Within the XBeach model, the coordinates are in Universal Transverse Mercator (UTM). Vertical datum is in North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 m. The XBeach model simulates morphologic change that results from hydrodynamic impacts and sediment transport. Model setup is outlined in Passeri and others, 2018. Boundary conditions in the form of water level and wave spectra were extracted from Bilskie and others, 2016. Simulated model topographic and bathymetric elevations are output at the end of each scenario. 2017 Davina Passeri U.S. Geological Survey Research Civil Engineer mailing and physical address
