Abstract

The navigation mission of the U.S. Army Corps of Engineers (USACE) was established in 1824 to provide safe, reliable, and efficient waterborne transportation system s. Today the USACE manages over 40,000 km of coastal and inland navigation channels, dredging 174 Million cubic met ers of sediment costing $1,322 Million in 2011. The Coastal Inlets Research Program (CIRP) advances the state of knowledge and engineering technology to improve management of coastal inlets, navigation channels, navigation str uctures, and adjacent beaches. This paper discusses CIRP advances in modeling coastal inlets and adjacent beaches, estim ating navigation channel shoaling, and regional sed iment management through placement of mixed-sized sediment in the nearshore. Challenges facing the USACE are discussed, including increased channel shoaling with New Panamax channel dimensions and uncertainty in future climate change.
