I dunno - it didn't seem difficult, per se, just too academic. I'd love to take the college course that this would be read for. I did wind up exploring all the pictures and now know some more about big dams than I used to, though! I also learned that concrete releases heat as it hardens. Check that out next time you see a fresh sidewalk setting. An episodic examination of how the agricultural development mission of the Bureau of Reclamation and the U.S. Army Corps of Engineer's concerns with river navigation recombined to produce the great multi-purpose dams of the 1930s, where power generation was a major consideration. This is despite the opposition of private power interests; power generation being the surest way to finance these great structures. Besides the institutional and economic politics that swirled around the projects chosen for examination, the authors spend almost half of the book on the engineering considerations involved in how these dams were designed and built. The shadow hanging over this effort would appear to be the St. Francis Dam Disaster of 1928 in California, the failure of which discouraged the examination of design approaches that would have been more technological daring and possibly more cost effective; better safe than sorry became the order of the day, despite the extra fiscal outlays incurred. I could easily have marked this book down for having all the flair of a text book, and I've read my share of dry-as-dirt books that I mostly read to be informed. aucune critique | ajouter une critique
The massive dams of the American West were designed to serve multiple purposes: improving navigation, irrigating crops, storing water, controlling floods, and generating hydroelectricity. Their construction also put thousands of people to work during the Great Depression. Only later did the dams? baneful effects on river ecologies spark public debate. Big Dams of the New Deal Era tells how major water-storage structures were erected in four western river basins. David P. Billington and Donald C. Jackson reveal how engineering science, regional and national politics, perceived public needs, and a river?s natural features intertwined to create distinctive dams within each region. In particular, the authors describe how two federal agencies, the Army Corps of Engineers and the Bureau of Reclamation, became key players in the creation of these important public works. By illuminating the mathematical analysis that supported large-scale dam construction, the authors also describe how and why engineers in the 1930s most often opted for massive gravity dams, whose design required enormous quantities of concrete or earth-rock fill for stability. Richly illustrated, Big Dams of the New Deal Era offers a compelling account of how major dams in the New Deal era restructured the landscape?both politically and physically?and why American society in the 1930s embraced them wholeheartedly.
