The topic of this Regional Sediment Management RSM Technical Note serves as an example of opportunities for implementation of RSM practices within the U.S. Army Engineer District, Jacksonvilles Operations and Maintenance OM Program, in dredging of the Intracoastal Waterway IWW within the state of Florida, authorized from the St. Johns River in Jacksonville to Key West. Inclusive of the eastern coast, the Atlantic Intracoastal Waterway AIWW is a canalized inland water-course that runs on the eastern coast of the United States, from Key West, Florida, to Boston, Massachusetts. The Federal authorized project for the AIWW is from Norfolk, Virginia, to the St. Johns River in Jacksonville, Florida. The IWWs extension, the Gulf Intracoastal Waterway GIWW, runs from Apalachee Bay, Florida, in northwestern Florida along the panhandle, to Brownsville, Texas, the southernmost tip of Texas, and from San Carlos Bay, Fort Myers, Florida to Anclote River north of Clearwater Beach along the southern Gulf Coast. For more than 4,023.4, km 2,500 miles along the Atlantic and Gulf of Mexico coasts, the system affords a channel for barges and other light-draft vessels. It is a navigable interconnected thread of passages running between the mainland and offshore islands, along rivers, through coastal sounds, lakes, lagoons, bays, and canals with a minimum depth of 3.7 m 12 ft throughout most of its length and a maintained depth of only 2.4 m 8 ft in some sections. The AIWW is subject to numerous dredging efforts under the OM Dredging Program and is a source of dredged material that has opportunities for many beneficial uses.
