Dams are critical structures in the sense that damage or breach of even a small dam may cause an unacceptable loss of life and property. Therefore, the safety of dams over the intended lifespan is of utmost importance for unrestricted operation. The basic prerequisites for any safe and successful operation of a dam include state-of-the-art design, experimental investigations of the construction material and properties of the foundation, a refined theoretical analysis of relevant load cases, and high-quality construction. In the past decades, many advancements have been achieved in both construction technologies and design, including those for the prediction of the long-term behavior of dams under various loading conditions. As such, this book examines these advancements with respect to the design, construction, and performance of earth, rockfill, and concrete dams. Over eight chapters, this book provides a comprehensive overview of the latest progress and research in dam engineering.

This is the story of the human effort that went into completing oneof the most complex feats of engineering in Alabama history, the buildingof four major hydroelectric dams by the Alabama Power Company.Between 1910 and 1930 the Alabama Power Company builtfour major hydroelectric projects: Lay Dam (1914), Mitchell Dam (1923),and Jordan Dam (1929) on the Coosa River and Martin Dam (1926) on the TallapoosaRiver. When the turbines began spinning and electricity began to flowfrom the power houses to farms, towns, and cities, Alabama moved from the19th into the 20th century.Constructed in remote areas of the state, the dams wereunique projects, yet they all had elements in common. The company had tobuild transportation networks to get men and material to the sites. Workers,skilled and unskilled, black and white, were recruited, brought in, housed,and fed. When wives and children joined the men, worker camps became towns,with schools, churches, medical clinics, and recreational facilities. Thesetowns were at once a reflection of their culture--and a look into a futurethat electricity would make possible.Putting "Loafing Streams" to Work is the story oflife in the towns and on the jobs. This story will help us better understandthe impact of Alabama Power's early activities and how Alabamians respondedto the forces of industrialization.

"After the death of his paddling companion, a German shepherd-labrador retriever mix named Jasper, Kim Trevathan began a series of solitary upstream kayaking quests in search of what he calls "liminal zones," transitional areas where dammed reservoirs give way to the current of the rivers that feed them. For four years he scoured the rivers and lakes of America, where environmentally damaging, and now decaying, man-made structures have transformed the waterways. In this thoughtful work, he details his upriver adventures, describing the ecological and aesthetic differences between a dammed river and a free-flowing river and exploring the implications of what liminal zones represent--a reassertion of pure, unadulterated nature over engineered bodies of water. Trevathan began by exploring the rivers and creeks of his childhood: the Blood River and Clarks River in western Kentucky. He soon ventured out to the Wolf River, the Big South Fork of the Cumberland, and other waterways in Tennessee. In 2008, he looped around the country with trips to Indiana's Tippecanoe River, Montana's Clearwater River, Oregon's Deschutes and Rogue Rivers, and Colorado's Dolores River, as well as adventures on such southeastern rivers as the Edisto, the Tellico, and the Nantahala. To Trevathan, paddling upstream became a sort of religion, with a vaporous deity that kept him searching. Each excursion yielded something unexpected, from a near-drowning in the Rogue River to a mysterious fog bank that arose across the Nantahala at midday. Throughout Liminal Zones, Trevathan considers what makes certain places special, why some are set aside and protected, why others are not, and how free-flowing streams remain valuable to our culture, our history, and our physical and spiritual health. This contemplative chronicle of his journeys by water reveals discoveries as varied and complex as the rivers themselves."--
