The two-dimensional XBeach model can be applied to barrier islands to solve for time-dependent elevations (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 elevation 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 (2025). Purpose: These data were generated to examine the effects of restoration alternatives on barrier island morphology at Little Dauphin Island, AL. Katrina_R3_elevation.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 (Northing and Easting) and the initial (z_initial) and post-storm final (z_final) model elevation values, in meters, for the Hurricane Katrina R3 (beach and dune restoration) alternative scenario.
