Inland navigation: Locks, Dams,and Channels (ASCE Manuals and Reports on Engineering Practice No. 94) was prepared by a task committee of the Waterways committee, which is part of the Waterways, Ports, Coastal, and Ocean Division. The manual provides information on planning, design, construction, and operation of the US waterways used by barge traffic. Most of the information comes from design criteria and more than 100 years of experience of the US Army Corps of Engineers. The Corps has built more than 220 lock and dam projects on US waterways and maintains more than 25,000 miles of inland navigation channels. This Manual also includes an inventory of the Corps lock and Dam projects and 6 case histories.
