This book presents a comprehensive overview of the firstlongitudinal study of the downstream response of a major river tothe establishment of a large hydropower facility and dams. PeaceRiver, a northward flowing boreal river in northwestern Canada wasdammed in 1967 and the book describes the morphologicalresponse of the 1200 km downstream channel and the response ofriparian vegetation to the change in flow regime over the firstforty years of regulated flows.Beginning with a description of the effect of regulation on theflow and sediment regimes of the river, the book proceeds to studychanges in downstream channel geometry on the main stem, on thelowermost course of tributaries, and on the hydraulic geometry, theoverall morphology of the channel, and riparian vegetationsuccession. The river is subject to annual freeze-up and break-up,so a chapter is devoted to the ice regime of the river. A chaptercompares the effects of two extraordinary post-regulation floodevents. The penultimate chapter presents a prediction of theultimate equilibrium form of the regulated river based on rationalregime theory. An online database of all the mainobservations will provide invaluable material for advanced studentsof river hydraulics and geomorphology.This book carefully brings together a range of studies that havebeen previously inaccessible providing a rare and comprehensiveanalysis of the effects of a big dam on a river, a river thatitself represents an example of the kind of system that islikely to receive considerable attention in the future from damengineers and environmentalists.* An invaluable reference to river scientists, hydroelectricpower developers, engineers and environmentalists* Focus on a northward flowing boreal river, a type thatholds most of the remaining hydroelectric power potential in theNorthern Hemisphere* Exceptional separation of water and sediment sources,permitting study of the isolated effect of manipulating one of thetwo major governing conditions of river processes and form* Unique example of water regulation and both natural andengineered flood flows* Detailed study of both morphological changes of the channeland of the riparian vegetation* Online data supplement including major data tables andnumerous maps. Details of the main observations and providesmaterial for problem study by advanced students of river hydraulicsand geomorphology are provided
