The uncertainty in morphologic response of storm-impact models and their use in short-term hazard forecasting and decadal forecasting is important to account for when considering a coupled model framework. Mickey and others (2020) provided a methodology to investigate uncertainty of profile response within the storm impact model, XBeach, related to varying antecedent topographies. A parameterized island Gaussian fit (PIGF) model generated an idealized baseline profile and a suite of idealized profiles that vary specific characteristics based on collated observed light detection and ranging (lidar) data collected from Dauphin Island, AL, between 2005 and 2015. The model inputs of idealized topography and bathymetry values for simulation of synthetic storm evolution with XBeach are described in Mickey and others (2020) and included in this USGS data release. Purpose: These data were generated to examine the sensitivity of storm response in the XBeach model to varying antecedent topography of a barrier island. The merged, one-dimensional (1D) topographic and bathymetric profile for the baseline idealized profile is included in the download file, Initial_Model_Baseline.zip, as a Network Common Data Form (NetCDF) file. This dataset consists of Federal Geographic Data Committee (FGDC) metadata and a NetCDF file, Initial_Model_Baseline.nc, containing the following variables: coordinates of the model domain (Easting and Northing) and the initial bathymetry/topography elevation (z) of the baseline model profile. All other NetCDF files contain the same variables but for a modified version of the baseline profile (last part of file name corresponds to modified profile characteristic).
