The XBeach model solves coupled 2-dimensional, horizontal wave propagation equations to predict flow, sediment transport, and bottom changes for varying spectral wave and flow boundary conditions (Roelvink and others, 2009 ). The XBeach model setup requires the input of a merged topographic and bathymetric 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 at the seaward model boundary that span the duration of each storm bin. The Xbeach model input and output of topography and bathymetry resulting from simulation of storm-impact scenarios at the Chandeleur Islands, LA, as described in USGS Open-File Report 2017–1009 are provided via a USGS data release (storm scenario bins where no events were observed are excluded). For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Mickey and others (2017). Purpose: These data were generated from the XBeach model to indicate how an idealized berm structure would evolve under varying magnitudes of storm conditions. Storm_Scenario_20.zip, is a dataset consisting of Federal Geographic Data Committee (FGDC) metadata and a NetCDF file containing the following variables: coordinates of the model grid (Easting and Northing); the final bathymetry/topography model grid for Scenario 20 (zend_20).

Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical datum is in North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.01 m. Lineage: Process_Step: Process_Description: The XBeach model simulates morphologic change that results from hydrodynamic impacts and sediment transport. Following the steps provided in the XBeach user manual (http://xbeach.readthedocs.io/en/latest/user_manual.html), the model was set up using a params.txt file (an example Xbeach model input file can be found in the appendix of OFR 2017-XXX). Significant wave heights and peak wave periods were provided from the representative scenario binning method outlined in Mickey and others (2017). The model was then executed and the resulting topographic and bathymetric elevations, calculated at the end of each scenario, were output into an intermediary MATLAB grid (.grd format).
