Download or read book The Regulation of Peace River written by Michael Church and published by John Wiley & Sons. This book was released on 2014-10-14 with total page 296 pages. 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

Download or read book The Effects of Flow Regulation on Freeze up Regime Peace River Taylor to the Slave River written by David Donald Andres and published by The Study. This book was released on 1996 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the effects of flow regulation on the freeze-up processes of part of the Peace River downstream of the Bennett Dam, which has regulated the river flow since 1972. Ice modelling and a review of ice observations and other field data were used to characterise the extent of flow regulation and its effects on ice in the river channel. Explicit equations and algorithms are presented that quantify the processes by which an ice cover forms on large regulated and non-regulated rivers. Work previously undertaken on the Peace River is also described to provide a framework for the calibration of these algorithms for the river in both its regulated and non-regulated condition. A procedure was developed for forecasting freeze-up on a non-regulated river and a stability relationship was derived that uses both air temperature and discharge to determine whether a juxtaposed or consolidated ice cover will form. In addition, the hydraulic characteristics of the Peace River were evaluated for six reaches using the existing data base.

This book was released on 1997 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes results of an investigation into the impacts of regulation on the Alberta portion of the Peace River channel and its associated vegetative cover downstream of the Bennett Dam in British Columbia, installed in 1967. Four representative reaches of the river totalling 500 kilometres were selected for examination of changes between 1968 and 1993. Study methodology involved constructing maps of river morphology and principal riparian vegetation communities from air photographs taken at various dates. In addition, extended vegetation mapping was provided on the 1993 maps to show the valley-side vegetation beyond the riparian zone. Morphological changes are summarized in 31 sub-reaches of 10-25 kilometres in length. River morphology is summarized in six major elements: water surface, unvegetated and vegetated bar surface, island surface, floodplain surface, and tributary alluvial fans within the floodplain. A dominant pattern of riparian succession is also noted.

This book was released on 1996 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.

Download or read book Hydrometeorological Conditions Controlling Ice jam Floods Peace River Near the Peace Athabasca Delta written by Terry Donald Prowse and published by The Study. This book was released on 1996 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common perception since the 1970s was that lower flows on the Peace River resulting from regulation precluded the generation of flood levels that would inundate perched basins that are separated from the open-water flow system. However, some literature references and local inhabitants have said that ice jams also played a role in some flood events. The initial objective of this study was to determine the relative role of ice jams in flooding in the Peace-Athabasca Delta (PAD). Assuming ice jams to be a significant factor, a second objective was to determine the hydrometeorological conditions that lead to their generation near the PAD and a third objective was to determine what role flow regulation has had on their formation. The study uses analysis of hydrometric data in conjunction with various historical and local sources to show the extent to which open water floods could flood the higher elevations in the PAD.

Download or read book A Hydraulic Flood Routing Model of the Peace River Hudson Hope to Peace Point written by Faye Ellen Hicks and published by . This book was released on 1996 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a hydraulic flood routing model developed to accurately model the open water river discharge of moderate floods. The model is capable of modelling the open water discharge at intermediate sites along the Peace River where no discharge data exist. The final geometric model consists of over 1,100 computational nodes describing channel width, effective bed elevation, and channel roughness. The hydraulic flood routing model used was the cdg-1D finite element model developed at the University of Alberta. The model provides for a solution of the fully dynamic, one-dimensional open channel flow equations. In its first stage, the model covers the Peace River from Hudson's Hope to Peace Point; subsequent work will focus on extending the model to the Slave River delta and collecting additional cross- section data on the Peace River.

This book was released on 1996 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to address instream flow needs (IFN) in the Northern River Basins Study arises primarily from issues related to flow regulation on the Peace River. Flow regulation may have effects on fish habitats and has clearly affected riparian habitats in the study area. This report presents proceedings of a workshop held to review methods and approaches for conducting IFN analyses, to consider their applicability to the northern river basins, and to develop recommendations for undertaking IFN investigations as part of the Study. The workshop included two sessions, one on IFN related to fisheries and aquatic habitats and one on IFN related to riparian and delta habitats. Topics of presentations and papers include river hydrology, water quality considerations, vegetation studies, instream flow assessment, winter habitat, implications of river impoundment, modelling of wildlife habitat, channel morphology, sediment transport, and wetland vegetation management.
