Using version 5527 of the XBeach numerical model (Roelvink and others, 2009), barrier island morphological change was simulated at Dauphin Island, Alabama (AL), for a 30-year forecast of multiple storms and sea level rise, considering scenarios of no-action and beach and dune nourishment as described in Passeri and others (2021). The two-dimensional XBeach model can be applied to barrier islands to solve for time-dependent topography and bathymetry. The XBeach model setup requires the input of topographic and bathymetric elevations at each grid cell. Model inputs and outputs in the form of topography and bathymetry at each grid cell are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2021).
These data were generated for the XBeach model to examine the effectiveness of nourishment in decadal barrier island morphological resilience at Dauphin Island, AL. Initial_Elevations_N.zip is a dataset consisting 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 initial bathymetric/topographic (z) model elevation values, in meters, for the nourishment scenario.

The initial topographic and bathymetric elevations are supplied at each model grid cell and serve as input for the initial nourishment scenario.
These are the complete initial model elevations for the nourishment 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 dataset contains the initial model geospatial information and topographic/bathymetric elevations for the nourishment scenario. Within the XBeach model, the coordinates are provided in the Universal Transverse Mercator (UTM) coordinate system; elevations are provided in meters (m).
The vertical datum used for the elevation data is the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 m.

Initial model grid and elevations that were modified to represent the nourishment scenario.
Mathworks MATLAB (R2017a) software was used to alter the OFR 2020-1001 inputs of the XBeach model to represent the nourishment scenario according to the methods described in Passeri and others (2021). This dataset, Initial_Elevations_N.nc provides the initial model elevations for the nourishment scenario. The initial model elevations were then packaged into a NetCDF file using the functions available in Mathworks MATLAB (R2017a) for inclusion in this data release.
