Book Description
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.

Book Description
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

Book Description
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.

Book Description
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).

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The Northern River Basins Study was established to examine the relationship between industrial, municipal, agricultural and other developments and the Peace, Athabasca and Slave River basins. Over 4 1/2 years about 150 projects or 'mini studies' were contracted by the Study under eight component categories including contaminats, drinking water, nutrients, traditional knowledge, hydrology / hydraulics, synthesis and modelling, food chain and other river uses.
