Fleet Forecasts for the United States to 2020 (1991)
The distribution of vessel sizes that will serve U.S. ports is a critical assumption in Corps of Engineers planning studies to determine potential benefits of harbor improvement projects. The planning horizon for such studies requires fleet forecasts that go beyond those routinely used for shipping industry purposes. The forecast is limited to vessels serving U.S. foreign trade, but is based on analysis of worldwide shipping supply and demand. Global seaborne trade projections were developed by DRI/McGraw-Hill in cooperation with Temple, Barker 4 Sloane, Inc. (TES). Lloyd's Maritime Services, Ltd. (LMIS) provided data on ship utilization, construction, and scrapping. A model developed by TES related supply to demand and accounted for vessel redeployments, retirements, and additions to fleet capacity. The forecasts are in tons of cargo available and tons of ship capacity, by size range for 11 vessel types, for 75 trade routes serving five U.S. coastal ranges (North Atlantic, South Atlantic, Gulf, North Pacific, South Pacific). Forecast intervals are 1995, 2000, 2010, and 2020.

Maritime Transportation System: Trends and Outlook (2007)
USACE major responsibilities for waterborne commerce include dredging, development and maintenance of the inland and coastal waterways and related maritime infrastructure, and navigation aids. A firm understanding of marine transportation conditions and trends is critical in discharging those responsibilities. The U.S. Maritime Transportation System (MTS) no longer exists in isolation, but must interact with ports, land carriers, customers, communities, environmental restrictions and security concerns. This second in a series of Water Resources Outlook papers is intended to develop an understanding of the challenges faced by the MTS over the next 30 years and suggests roles for the private and governmental sectors, including the Corps. It is intended to provide a strong, fact-based foundation for policy, planning and priorities.

Implementation Guidance for Section 125(a)(2)(C) of the Water Resources Development Act of 2020, Beneficial Use of Dredged Material (2022)
Section 125(a)(2)(C) of the Water Resources Development Act (WRDA) of 2020 amends Section 204(d) of WRDA 1992 (33 U.S.C. 2326(d)) to authorize the Secretary of the Army for Civil Works to use funds appropriated for construction or operation and maintenance of a project involving the disposal of dredged material when selecting a disposal method that is not the least cost option based on a determination that the incremental costs of the disposal method are reasonable in relation to the environmental benefits or the hurricane and storm or flood risk reduction benefits. This memorandum provides guidance and direction on implementation of Section 125(a)(2)(C) and rescinds and replaces the implementation guidance for Section 1038 of the Water Resources Reform and Development Act of 2014.
