Book Description
For the past few years, the Corps has been working on what is known as the Restructured Upper Mississippi River-Illinois Waterway Feasibility Study, the heart of which is a multibillion-dollar proposal to double the length of up to a dozen locks on the river. The Research Council first reviewed the feasibility study in 2001 during controversies over the accuracy of models being used by the Corps to justify lock expansion based on increased demand for barge transportation. More than 100 million tons of cargo-half of it grain destined for international markets, the other half goods such as construction materials, coal, and chemicals-are shipped along the navigation system each year. The locks, which along with dams allow barges to traverse uneven river depths, were originally designed for "tows" of barges up to 600 feet long, but the length of a typical tow has increased, forcing the Corps to look for ways to relieve congestion. The book finds the U.S. Army Corps of Engineers has made good progress in broadening its proposed plan for navigation improvements on the Upper Mississippi River-Illinois Waterway system to give greater consideration to ecological restoration. However, the plan still does not provide sufficient economic justification for expanding locks on the rivers because of flaws in the models the Corps used to predict demand for barge transportation. Little attention is paid to inexpensive, nonstructural navigation improvements that could help better manage existing levels of barge traffic. The revised plan has been usefully expanded to include many creative and potentially useful ecosystem restoration measures. These measures, however, should be more firmly grounded in river science principles and more broadly consider ways the river's ecology might affect or be affected by navigation, recreation and other uses.

Book Description
In 1988, the U.S. Army Corps of Engineers began an investigation of the benefits and costs of extending several locks on the lower portion of the Upper Mississippi River-Illinois Waterway (UMR-IWW) in order to relieve increasing waterway congestion, particularly for grain moving to New Orleans for export. With passage of the Flood Control Act of 1936, Congress required that the Corps conduct a benefit-cost analysis as part of its water resources project planning; Congress will fund water resources projects only if a project's benefits exceed its costs. As economic analysis generally, and benefit-cost analysis in particular, has become more sophisticated, and as environmental and social considerations and analysis have become more important, Corps planning studies have grown in size and complexity. The difficulty in commensurating market and nonmarket costs and benefits also presents the Corps with a significant challenge. The Corps' analysis of the UMR-IWW has extended over a decade, has cost roughly $50 million, and has involved consultations with other federal agencies, state conservation agencies, and local citizens. The analysis has included many consultants and has produced dozens of reports. In February 2000, the U.S. Department of Defense (DOD) requested that the National Academies review the Corps' final feasibility report. After discussions and negotiations with DOD, in April 2000 the National Academies launched this review and appointed an expert committee to carry it out.

Book Description
Excerpt from Final Report of the National Waterways Commission, 1912 The plan of impounding reservoirs on the tributaries of the Ohio to prevent floods and improve navigiation was pointed out by Mr. M. O. Leighton. In his report to the nlend Waterways Commission in 1908. Since that time the subject has been thoroughly investi gated by the Pittsburgh Flood Commission, which will soon publish an exhaustive report. This commission, composed of prominent engi ncore, examined in detail 43 reservoir sites on the Allegheny, Monon gahela. And their tributaries, with special reference to the prevention of damage from floods at Pittsburgh. They recommend the adop tion of a system composed of 17 reservoirs, costing Thlil detailed estimates of their plan are shown by the following ta e.
