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

Environmental Indices: Systems Analysis Approach examines the theoretical development of environmental indices and their practical application. Indicators can be powerful tools in guiding data and information collection processes, and careful development will lead to more focused and cost-effective global monitoring and observing systems at international level. The authorship is drawn from a group of internationally distinguished scientists and researches who are actively working towards a comprehensive set of tools and protocols such as simulation models, fuzzy clustering analysis and GIS methodologies that will lead to the development of meaningful environmental indices. This book will be a vital reference work for students, teachers and researches, together with policy makers, planners and all professional involved in development programs.

Describes a hydraulic flood routing model developed to accurately model the open water river discharge on the Peace and Slave rivers. The model is capable of modelling the discharge at sites where no discharge data exist. The document includes description of the development of the database for the model, including the geometric database (channel distances, surface slopes, bed profiles, channel widths and resistances) and the hydrologic data. The appendix includes a user manual for the user-friendly microcomputer program that has been set up to run historical flows (1961-93) and to simulate naturalised flows on the Peace River (1969-91).

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.
