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
The Mississippi River is, in many ways, the nation's best known and most important river system. Mississippi River water quality is of paramount importance for sustaining the many uses of the river including drinking water, recreational and commercial activities, and support for the river's ecosystems and the environmental goods and services they provide. The Clean Water Act, passed by Congress in 1972, is the cornerstone of surface water quality protection in the United States, employing regulatory and nonregulatory measures designed to reduce direct pollutant discharges into waterways. The Clean Water Act has reduced much pollution in the Mississippi River from "point sources" such as industries and water treatment plants, but problems stemming from urban runoff, agriculture, and other "non-point sources" have proven more difficult to address. This book concludes that too little coordination among the 10 states along the river has left the Mississippi River an "orphan" from a water quality monitoring and assessment perspective. Stronger leadership from the U.S. Environmental Protection Agency (EPA) is needed to address these problems. Specifically, the EPA should establish a water quality data-sharing system for the length of the river, and work with the states to establish and achieve water quality standards. The Mississippi River corridor states also should be more proactive and cooperative in their water quality programs. For this effort, the EPA and the Mississippi River states should draw upon the lengthy experience of federal-interstate cooperation in managing water quality in the Chesapeake Bay.

Book Description
While John McPhee was working on his previous book, Rising from the Plains, he happened to walk by the engineering building at the University of Wyoming, where words etched in limestone said: "Strive on--the control of Nature is won, not given." In the morning sunlight, that central phrase--"the control of nature"--seemed to sparkle with unintended ambiguity. Bilateral, symmetrical, it could with equal speed travel in opposite directions. For some years, he had been planning a book about places in the world where people have been engaged in all-out battles with nature, about (in the words of the book itself) "any struggle against natural forces--heroic or venal, rash or well advised--when human beings conscript themselves to fight against the earth, to take what is not given, to rout the destroying enemy, to surround the base of Mt. Olympus demanding and expecting the surrender of the gods." His interest had first been sparked when he went into the Atchafalaya--the largest river swamp in North America--and had learned that virtually all of its waters were metered and rationed by a U.S. Army Corps of Engineers' project called Old River Control. In the natural cycles of the Mississippi's deltaic plain, the time had come for the Mississippi to change course, to shift its mouth more than a hundred miles and go down the Atchafalaya, one of its distributary branches. The United States could not afford that--for New Orleans, Baton Rouge, and all the industries that lie between would be cut off from river commerce with the rest of the nation. At a place called Old River, the Corps therefore had built a great fortress--part dam, part valve--to restrain the flow of the Atchafalaya and compel the Mississippi to stay where it is. In Iceland, in 1973, an island split open without warning and huge volumes of lava began moving in the direction of a harbor scarcely half a mile away. It was not only Iceland's premier fishing port (accounting for a large percentage of Iceland's export economy) but it was also the only harbor along the nation's southern coast. As the lava threatened to fill the harbor and wipe it out, a physicist named Thorbjorn Sigurgeirsson suggested a way to fight against the flowing red rock--initiating an all-out endeavor unique in human history. On the big island of Hawaii, one of the world's two must eruptive hot spots, people are not unmindful of the Icelandic example. McPhee went to Hawaii to talk with them and to walk beside the edges of a molten lake and incandescent rivers. Some of the more expensive real estate in Los Angeles is up against mountains that are rising and disintegrating as rapidly as any in the world. After a complex coincidence of natural events, boulders will flow out of these mountains like fish eggs, mixed with mud, sand, and smaller rocks in a cascading mass known as debris flow. Plucking up trees and cars, bursting through doors and windows, filling up houses to their eaves, debris flows threaten the lives of people living in and near Los Angeles' famous canyons. At extraordinary expense the city has built a hundred and fifty stadium-like basins in a daring effort to catch the debris. Taking us deep into these contested territories, McPhee details the strategies and tactics through which people attempt to control nature. Most striking in his vivid depiction of the main contestants: nature in complex and awesome guises, and those who would attempt to wrest control from her--stubborn, often ingenious, and always arresting characters.

Book Description
Named by Algonkian-speaking Indians, Mississippi can be translated as "Father of Waters." The river, the largest in North America, drains 31 states and 2 Canadian provinces, and runs 2,350 miles from its source to the Gulf of Mexico. The Mississippi River is truly one of the great forces that has shaped the United States into the country it is today. Although its role has changed over the past few centuries, the Mississippi has always been important to those who lived along its banks. Indigenous peoples fished its waters and depended on the waterway for transportation. Explorers and traders traveled the river in hopes of conquering more land and obtaining wealth for their countries. Settlers moved close to take advantage of the rich farmland the river provided. All of these pursuits resulted in a trade industry that brought about a social and economic transformation, when news and goods made their way downriver and livelihoods were provided. In fact, the Mississippi River's economic and strategic value was so important that when Ulysses S. Grant won the siege of Vicksburg and control of the river during the Civil War, the Confederacy was dealt a serious blow. Today, although still used to transport goods, the river has taken on yet another identity: that of entertainer. Literature, pleasure boats, and floating casinos all showcase a new dimension of this magnificent river.
