For further information regarding model input generation and visualization of model output topography and bathymetry refer to Mickey and others (2020). Purpose: These data were generated for the Delft 3D, EDGR, and XBeach model to indicate how Dauphin Island evolved over the span of approximately 10 years. The model-derived topographic and bathymetric digital elevation model (DEM) is included in the download file, Final_Model_DEM.zip as a Network Common Data Form (NetCDF) file. This dataset consists of Federal Geographic Data Committee (FGDC) metadata and a NetCDF file containing the following variables: coordinates of the model grid (Easting and Northing) and the final bathymetry/topography elevation (z) model grid.

Completeness_Report: This DEM contains the complete final model grid elevation. 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This DEM contains the final model topographic and bathymetric elevations. Within the Delft 3D, EDGR, and XBeach models, the coordinates are in Universal Transverse Mercator (UTM) Zone 16 North. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical datum is the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 meters (m). Lineage: Process_Step: Process_Description: The hindcast model simulates morphologic change that results from hydrodynamic impacts and sediment transport with Delft 3D, XBeach, and an empirical dune growth model (EDGR). The Delft 3D modelling portion was set up following the description provided in Jenkins and others (2020). Following the steps provided in the XBeach user manual (https://xbeach.readthedocs.io/en/latest/user_manual.html), the model was set up using a params.txt file. Significant wave heights, peak wave periods, and water levels were provided from the synthetic storm scenario described in OFR 2019-1139 by Mickey and others (2020). The EDGR dune growth model was executed between the Delft 3D and XBeach model simulations and the model was set up following the description in Mickey and others (2020). The resulting topographic and bathymetric elevations, extracted at the end of each scenario, were output into netCDF files.
