How do engineers tame a river, and what happens when they get it wrong?\u003c\/p\u003e\u003cp\u003eEdward Callenford explores the science, history, and future of the dam: why an arch dam can be thinner than you would ever dare while a gravity dam relies on sheer mass, how water pressure and uplift threaten to overturn or slide a structure, why spillways and foundations decide life and death, and what the failures of the past taught a cautious profession. He weighs the immense benefits, power, water, flood control, against the human and environmental costs that make dams among the most consequential structures we build.\u003c\/p\u003e\u003cp\u003eBalanced, vivid, and illustrated with original diagrams, this is the definitive popular guide to the concrete giants that reshape rivers and nations.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Edward Callenford\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798188600631\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/23\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 134\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.54lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 10.00h x 7.00w x 0.29d","brand":"Edward Callenford","offers":[{"title":"Paperback","offer_id":50665955885311,"sku":"9798188600631","price":9.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/how-dams-hold-back-a-edward-callenford-9798188600631","provider":"WR Book House","version":"1.0","type":"link"}
