Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.
2020 Winner of the Southwest Book Awards 2020 Spur Awards Finalist Contemporary Nonfiction, Western Writers of America The Grand Canyon has been saved from dams three times in the last century. Unthinkable as it may seem today, many people promoted damming the Colorado River in the canyon during the early twentieth century as the most feasible solution to the water and power needs of the Pacific Southwest. These efforts reached their climax during the 1960s when the federal government tried to build two massive hydroelectric dams in the Grand Canyon. Although not located within the Grand Canyon National Park or Monument, they would have flooded lengthy, unprotected reaches of the canyon and along thirteen miles of the park boundary. Saving Grand Canyon tells the remarkable true story of the attempts to build dams in one of America’s most spectacular natural wonders. Based on twenty-five years of research, this fascinating ride through history chronicles a hundred years of Colorado River water development, demonstrates how the National Environmental Policy Act came to be, and challenges the myth that the Sierra Club saved the Grand Canyon. It also shows how the Sierra Club parlayed public perception as the canyon’s savior into the leadership of the modern environmental movement after the National Environmental Policy Act became law. The tale of the Sierra Club stopping the dams has become so entrenched—and so embellished—that many historians, popular writers, and filmmakers have ignored the documented historical record. This epic story puts the events from 1963–1968 into the broader context of Colorado River water development and debunks fifty years of Colorado River and Grand Canyon myths.
This study examines rising alarm over waste of natural resources, and its use by Theodore Roosevelt and his administration to further objectives of conservation and an American form of empire. These objectives encompassed both preservationist and utilitarian approaches, centred on efficiency, but interpreting efficiency in social and political rather than economic terms. These policies revealed an emerging idea of environmental 'habitability' that presaged modern interest in sustainability.
Will tensions and disputes among states sharing international water courses and lakes turn into active conflicts? Addressing this question, the book shows that these concerns are more prominent due to the locations and underlying political dynamics of some of these large rivers and the strategic interests of major powers. Written by a combination of leading practitioners and academics, this book shows that states are more prone to cooperate and manage their transboundary issues over the use of their common water resources through peaceful means, and the key institutions they employ are international river basin organizations (RBOs). Far from being mere technical institutions, RBOs are key mechanisms of water diplomacy with capacity and effectiveness varying on four key interrelated factors: their legal and institutional development, and the influence of their technical and strategic resources. The basins analyzed span all continents, from both developed and developing basins, including the Columbia, Great Lakes, Colorado, Senegal, Niger, Nile, Congo, Jordan, Helmand, Aral Sea, Mekong, Danube and Rhine. Contributing to the academic discourse on transboundary water management and water conflict and cooperation, the book provides insights to policy-makers on which water diplomacy engagements can be successful, the strengths to build on and the pitfalls to avoid so that shared water resources are managed in a cooperative, sustainable and stable way.
