Using version 52.30 of the ADvanced CIRCulation (ADCIRC) numerical model (Luettich and others, 1992), astronomic tides were simulated at Mobile Bay, Alabama (AL), under scenarios of Holocene geomorphic configurations representing the period of 3500 to 2300 years before present including a breach in the Morgan Peninsula and a land bridge at Pass aux Herons, as described in Smith and others (2020). The two-dimensional ADCIRC model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and transport scenarios. For this study, the ADCIRC unstructured finite element mesh domain spans to the 60th meridian west in the Atlantic Ocean and has higher spatial resolution elements (20 - 100 meters (m)) along the northern Gulf of Mexico coast from Louisiana through the Florida Panhandle. The ADCIRC model setup requires the input of topographic and bathymetric elevations at each mesh node. Model inputs in the form of topography and bathymetry and model outputs in the form of water levels and velocities at each mesh node are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Smith and others (2020).
These data were generated for the ADCIRC model to examine the effects of Holocene geomorphic configurations on astronomic tides in Mobile Bay, AL. Initial_Elevations_RS_MP.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 (longitude and latitude) and the initial bathymetric/topographic (z) model elevation values, in meters, for the reference scenario with the Morgan Peninsula breach.

The initial topographic and bathymetric elevations are supplied at each node of the unstructured finite element model mesh and serve as input for the reference scenario with Morgan Peninsula breach.
These are the complete initial model elevations for the reference scenario with the Morgan Peninsula breach. 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 reference scenario with the Morgan Peninsula breach. Within the ADCIRC model, the coordinates are provided in decimal degrees using the North American Datum of 1983 (NAD83) geographic coordinate system; elevations are provided in meters.
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 mesh and elevations that were modified to represent the reference scenario with Morgan Peninsula breach.
Aquaveo's Surface-water Modeling System (SMS) 12.0 software was used to alter the EF45 inputs of the large-domain hydrodynamic model included in Passeri and others (2016) to represent the reference scenario with the Morgan Peninsula breach, according to the methods described in Smith and others (2020). This dataset, Initial_Elevations_RS_MP.nc provides the initial model elevations for the reference scenario (RS) with the Morgan Peninsula (MP) breach. 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.
