Bird/Long Island is an ecologically/archaeologically-significant dredge-spoil island in the Savannah River under threat from sea level rise, shoreline change from natural and anthropogenic causes, and land subsidence. In addition to substantial tidal and freshwater flows, the island is subject to locally-generated wind waves primarily from northeast winds, as well as wake from container ships transiting to and from the Port of Savannah. The present work uses field data to characterize these hydrodynamic processes, improve modeling of the region, and identify the mechanisms driving the shoreline evolution.
