In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Effects of Late Holocene Climate and Coastal Change in Mobile Bay, Alabama: ADCIRC Model Input and Results

Summary
Using the numerical model ADCIRC, astronomic tides were simulated at Mobile Bay, Alabama 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 (see Figure 1), as described in Smith and others, 2020. Model inputs in the form of topography and bathymetry and model outputs in the form of water levels and velocity residuals (steady tidal currents) at each node of the unstructured finite element mesh are provided in this data release for each scenario. For further information regarding scenarios, model input generation and visualization of model output, refer to Smith and others, 2020.
