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.
“Anyone who is interested in Hurricane Katrina, and in America’s failing infrastructure, will want to read this book . . . a fast-paced narrative.” —Scott G. Knowles, Drexel University 2020 Nautilus Silver Winner In the aftermath of one of the worst disasters in US history, Words Whispered in Water tells the story of one woman’s fight, against all odds, to expose a mammoth federal agency—and win. In 2005, the entire world watched as a major US city was nearly wiped off the map. The levees ruptured and New Orleans drowned. But while newscasters attributed the New Orleans flood to “natural catastrophes” and other types of disasters, citizen investigator Sandy Rosenthal set out to expose the true culprit and compel the media and government to tell the truth. This is her story. When the protective steel flood-walls broke, the Army Corps of Engineers—with cooperation from big media—turned the blame elsewhere. In the chaotic aftermath, Rosenthal heroically exposes the federal agency’s egregious design errors and changes the narrative surrounding the New Orleans flood. This engaging and revealing tale of man versus nature and man versus man is a horror story, a mystery, and David and Goliath story all in one. “Reveals what it takes to hold the powerful to account.” —Publishers Weekly “There are only a few civilians that fight like real warriors. Sandy Rosenthal is one of them.” —Russel L. Honoré, Lieutenant General, United States Army (Ret.)
Based on the past 30-years' research on the technical and cultural values of China's Grand Canal, this book, based on interdisciplinary research, studies the natural and social background of the evolution and development of different sections of the Grand Canal in different historical periods, as well as the interrelations between the Grand Canal and the Chinese politics, economics, and culture. It also assesses the effects of the Grand Canal on the progress of the Chinese civilization, engineering technology achievement, the natural environment, and the society, providing the readers with an understanding of China's Grand Canal from the perspectives of hydraulic engineering and history.
Dams and Waterways, a title in the five-title series Frameworks: Science, Technology, and the Built Environment, illuminates the history, architecture, environmental impact, and scientific and engineering principles behind the design and construction of dams, canals, and other waterways around the world throughout history. Examples include aqueducts in the Roman Empire, the Hoover Dam, Aswan High Dam, Three Gorges Dam, and the Erie Canal. Dams and Waterways provides an interdisciplinary, visual approach that combines informative text, fascinating background information, and basic scientific principles with dozens of full-color photographs, illustrations, diagrams, and other visuals. It highlights the importance of structures that support essential functions of everyday life from the irrigation of crops to the generation of hydroelectric power. Appropriate for a broad audience of students, teachers, librarians, and general interest readers, Dams and Waterways is an excellent supplemental resource for subjects covered throughout the curricula: science, technology, and society; art and architecture; economics; and world history and culture.
