Download or read book Hydraulic Modelling of the Peace Athabasca Delta Under Modified and Natural Flow Conditions written by Bill Aitken and published by The Study. This book was released on 1994 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction of the Bennett Dam in British Columbia altered natural fluctuations of downstream flows in the Peace River in Alberta, with major implications for the ecosystem of the Peace-Athabasca Delta. In later years, downstream weirs were constructed to restore the water level regime in the Delta. This report presents the results of a modelling exercise undertaken in an attempt to assess the effect of the weirs and the dam on the Delta water levels during 1985-90, at which time Lake Athabasca water levels were low and it was not clear whether the weirs were functioning properly or if the low water levels were caused by low flows coming from the upper Peace and Athabasca river basins. The methodology uses a one-dimensional hydrodynamic model, suitably modified and calibrated. The appendices include numerous plots of water levels indicating the effects of the weirs and dam on natural conditions.

Book excerpt: Begins by showing where the northern river basin area of Alberta fits into various climate classifications, then presents current climate data for the northern basins in the form of tables, graphs, and figures. Some of the weather regimes that lead to given temperature and precipitation events across the basins are discussed. This is followed by description of specific meteorological phenomena such as winter weather, snow, permafrost, freezing rain, historical meteorological events such as floods, extreme temperatures, and storms, and an examination of aspects of climate with respect to climate-based activities such as agriculture. Appendices include maps of meteorological stations, temperatures, and precipitation.
Download or read book Water Resources Use and Management Issues for the Peace Athabasca and Slave River Basins written by Michael Williams and published by The Study. This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a survey of residents of northern Alberta river basins, respondents were asked to choose the best and worst examples of various sets of threats to water quality/quantity in the basins as well as best and worst examples of possible management actions. This report analyses the responses to the two sets of best/worst questions, using logistic regression. The analysis produced the following estimates: the probability that each of 11 possible threats to water quantity/quality will be selected as the area of most concern; and the probability of each of 11 possible management actions will be selected as the most effective response to such concerns. The probabilities produced by this analysis are ranked to determine the preferences of northern households and various stakeholder groups within the basin.

This book was released on 1996 with total page 116 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.

This book was released on 1995 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Northern River Basins Study Board will be formulating recommendations covering many areas likely of consequence or interest to basin residents. To assist the Board in this task, a series of projects was initiated to survey the residents on their use of northern river basins waters. Existing information was either not available or as extensive as required. This report details the background work undertaken to devise a survey instrument and strategy to capture for households a representative cross-section of information on water use and resident attitudes toward the water resource. The report also assesses the most effective means for approaching and obtaining information from stakeholder groups. The appendix includes the project terms of reference, a description of how the population stratification method could be applied for the survey, and a draft questionnaire.

Book excerpt: The Northern River Basins Study Board will be formulating recommendations covering many areas likely to be of consequence or interest to basin residents. To assist the Board in this task, a series of projects was initiated to survey the residents on their use of northern river basins waters. This report details the efforts undertaken to develop a list of stakeholders that should be approached for input in a workshop setting. These efforts included designing a stakeholder questionnaire, conducting a telephone survey, and analyzing the data. It also reviews the survey results, including the types and membership of stakeholder groups, use of river basins, water management and water use concerns, and preferred location and time of the proposed workshops. The appendix includes a copy of the questionnaire and a directory of stakeholder groups in the survey sample (by category).

Download or read book Proceedings of the Northern River Basins Study Instream Flow Needs Workshop October 14 15 1993 and January 6 7 1994 written by Gordon L. Walder and published by . 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.
