Title:
XBeach Bottom Friction Scenarios: Model Inputs and Results for Hurricane Ivan Initial Elevations
Abstract:
Using the numerical model XBeach version 4926 (Roelvink and others, 2009), various bottom friction scenarios were simulated for hurricanes Ivan (2004) and Katrina (2005) at Dauphin Island, Alabama as described in Passeri and others, 2018. The XBeach model setup requires the input of a merged topographic and bathymetric digital elevation model (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. Model inputs and outputs in the form of topography and bathymetry are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Passeri and others, 2018.

Why was the data set created?

These data were generated for the XBeach model to examine the influence of bottom friction on barrier island morphology during two storm events. Ivan_Initial_Elevations.zip is a dataset that consists 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 pre-Hurricane Ivan bathymetric/topographic (z) model elevation values, in meters.

  2. How were the data generated, processed, and modified?
    Date: 2017 (process 1 of 2)
    Esri ArcMap 10.2.2 was used to merge and interpolate bathymetric data from Danielson and others (2013), and topographic lidar survey data from the 1998 Fall Gulf Coast Lidar (LA to FL) Point Cloud files with Orthometric Vertical Datum NAVD88 using GEOID12A and 2001 USGS Coastal Lidar: Gulf of Mexico (TX to FL) Point Cloud files with Orthometric Vertical Datum NAVD88 using GEOID12A into a 3 m resolution seamless DEM following the methods of Medeiros and others, 2011. Mathworks MATLAB (R2015a) was used to interpolate the seamless DEM onto the model grid using Triangulation-based linear interpolation with the function, griddata. This merged topographic and bathymetric dataset provides the intial, pre-Hurricnae Ivan model elevations used to simulate each of the Hurricane Ivan friction scenarios.
