Available in PDF, EPUB and Kindle. Book excerpt: A series of field and laboratory experiments has shown that bed reworking by moderate floods in uniform reaches of steep, sand-bed ephemeral streams is predominantly by bedform development and migration, and not by general scour and fill. In two floods in the field experiment, maximum scour was 24 cm in the first and 66 cm in the second. Bedform amplitudes, estimated using well-established theoretical techniques and measurements of channel parameters, were 28 to 64 cm and 48 to 97 cm, respectively. In the laboratory experiment, maximum general scour and fill, calculated from the difference between measured sediment input and output rates in the flume, was about that of two sand grain diameters, and less than 3 percent of the amplitude of bedforms in the channel. Similar calculations show that scour and fill data reported in the literature are also compatible with bed reworking by bedforms.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of the first longitudinal study of the downstream response of a major river to the establishment of a large hydropower facility and dams. Peace River, a northward flowing boreal river in northwestern Canada was dammed in 1967 and the book describes the morphological response of the 1200 km downstream channel and the response of riparian vegetation to the change in flow regime over the first forty years of regulated flows. Beginning with a description of the effect of regulation on the flow and sediment regimes of the river, the book proceeds to study changes in downstream channel geometry on the main stem, on the lowermost course of tributaries, and on the hydraulic geometry, the overall morphology of the channel, and riparian vegetation succession. The river is subject to annual freeze-up and break-up, so a chapter is devoted to the ice regime of the river. A chapter compares the effects of two extraordinary post-regulation flood events. The penultimate chapter presents a prediction of the ultimate equilibrium form of the regulated river based on rational regime theory. An online database of all the main observations will provide invaluable material for advanced students of river hydraulics and geomorphology. This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists. • An invaluable reference to river scientists, hydroelectric power developers, engineers and environmentalists • Focus on a northward flowing boreal river, a type that holds most of the remaining hydroelectric power potential in the Northern Hemisphere • Exceptional separation of water and sediment sources, permitting study of the isolated effect of manipulating one of the two major governing conditions of river processes and form • Unique example of water regulation and both natural and engineered flood flows • Detailed study of both morphological changes of the channel and of the riparian vegetation • Online data supplement including major data tables and numerous maps. Details of the main observations and provides material for problem study by advanced students of river hydraulics and geomorphology are provided
