A fixed-bed model of Brunswick Harbor, constructed to scales of 1:500 horizontally and 1:100 vertically, reproduced approximately 67 square miles of prototype area beginning in St. Simons Sound and extending to the upper portions of the Brunswick and Turtle Rivers and including all of East River and Academy Creek, the extensive system of saltwater creeks and marshes that affect tidal action in the area, and the Intracoastal Waterway from Brunswick River through Jekyll Creek to the U.S. Highway 84 Bridge. The model was equipped with the necessary appurtenances for the accurate reproduction of tides, tidal currents, shoaling patterns, and other significant prototype phenomena. The primary purpose of the model study was to test the effectiveness of proposed plans for the reduction of shoaling in Brunswick Harbor; however, tests of plans to reduce shoaling in Jekyll Creek were later added to the overall testing program.
