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