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.

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

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 addresses the fundamental requirement for aninterdisciplinary catchment based approach to managing andprotecting water resources that crucially includes anunderstanding of land use and its management. In thisapproach the hydrological cycle links mountains to the sea, andecosystems in rivers, groundwaters, lakes, wetlands, estuaries andcoasts forming an essential continuum directly influenced by humanactivity. The book provides a synthesis of current and future thinking incatchment management, and shows how the specific problems thatarise in water use policy can be addressed within the context of anintegrated approach to management. The book is written for advancedstudents, researchers, fellow academics and water sectorprofessionals such as planners and regulators. The intention is tohighlight examples and case studies that have resonance not onlywithin natural sciences and engineering but with academicsin other fields such as socio-economics, law and policy.

"In the delta, water is boss, change is the only constant, and creation and destruction exist side by side." The Peace-Athabasca Delta in northern Alberta is a globally significant wetland that lies within one of the largest unfragmented landscapes in North America. Arguably the world's largest boreal inland delta, it is renowned for its biological productivity and is a central feature of a UNESCO World Heritage Site. Yet the delta and its indigenous cultures lie downstream of Alberta's bitumen sands, whose exploitation comprises one of the largest industrial projects in the world. Kevin Timoney provides an authoritative synthesis of the science and history of the delta, describing its ecology, unraveling its millennia-long history, and addressing its uncertain future. Scientists, students, leaders in the energy sector, government officials and policy makers, and conscientious citizens everywhere should read this lively work.

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.
