Coastal Erosion Analysis

Started:  2nd Quarter 2005
Complete: 4th Quarter 2006

Brief description:

The goal of this study is to evaluate the long-term coastal shoreline impacts of the proposed Savannah Harbor Expansion Project to the littoral system and the coastal shoreline.  The specific objectives of this study will be to assess the impact of deepening the Savannah Harbor navigation channel on the regional sediment budget and to quantify the influence of the deepening project on increased shoreline recession rates.  Included in this analysis are: 1) historical data analysis from existing reports and data sets which quantify the shoreline position change, bathymetry change, beach profile adjustments, dredging quantities and sediment type, wave and current patterns, storm frequency and magnitude, and water level fluctuations; and 2) hydrodynamic modeling, and wave transformation to document the impact of channel modifications on water level, current and wave propagation and sediment transport. The  analysis will  incorporate, as appropriate, the information produced by the  Beach Erosion Study .

Current status:

The coastal erosion analysis is complete.
