Abstract: Effective regional sediment management has the potential to significantly reduce operating costs for the U.S. Army Corps of Engineers but only if the ultimate sources and sinks of coastal sediment are fully quantified. Geochemical sedimentary markers provide a well-established methodology for fingerprinting the various sources and time frames over which sediment accumulates in regions of concern. This report outlines the basic methodology of how different geochemical signatures can be utilized to identify sources and fates of sediment. These methodologies are then showcased in example case studies (real and hypothetical) that address issues pertinent to the mission of the U.S. Army Corps of Engineers.
