First published in 1904, this pioneering engineering treatise examines the art and science of earth dam construction at a moment when the discipline was still defining itself. Bassell opens with a striking assertion: earth dams are among humanity's oldest structures, yet they remain wildly misunderstood. The popular assumption that anyone with a shovel and some clay can build a dam is precisely the kind of thinking that leads to catastrophe. Through careful analysis of failures including the devastating Johnstown Flood of 1889, Bassell demonstrates that earth dam engineering demands rigorous site investigation, deep knowledge of hydraulic principles, and meticulous attention to material selection. The book surveys various dam types, construction methodologies, and the critical factors that separate stable structures from deadly ones. Written before modern geotechnical science existed, this work captures a pivotal moment when engineers were systematizing centuries of empirical knowledge into formal design principles. For anyone interested in the history of engineering, infrastructure development, or the invisible systems that shape modern life, Bassell offers a fascinating window into how engineers learned to contain rivers.
