Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results from numerical models of the transport and fate of environmental chemicals in northern Alberta rivers. The models were developed using the USEPA WASP modelling system and were structured as one-dimensional (longitudinal) models with separate, interacting water column and bed sediment compartments. Seven selected organic chemicals were simulated over 1992-93 for the Athabasca River and over 1990-91 for the Wapiti/Smoky River system. Chemicals simulated included 2,3,7,8-tetrachloro dibenzofuran, dehydroabietic acid, and phenanthrene. The models were first calibrated for sodium and total suspended solids. Organic chemicals were simulated using a set of environmental fate constants developed from a literature search, numerical estimation software, and estimation from field data. Results of initial simulations were compared to observed data and adjustments made to selected constants to improve the calibration.

Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results using a revised model simulating the fate of contaminants in the Athabasca River. The revised fate model allows predictive sediment transport simulation within the WASP4 model framework, predicts resuspension from hydraulic information supplied by WASP4 and from user-supplied sediment characteristics, and can be applied to different flow conditions without having to re-describe sediment transport rates. Several simulations were run using input files from the original model calibration. Program listings of subroutines are included.

This book was released on 1997 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarizes the major modelling projects undertaken to model water quality in the Peace, Athabasca, and Slave river systems. The first section describes the scope of the problem of modelling water quality in large complex systems that are relatively oligotrophic, located at relatively high altitudes, and experience highly seasonal environmental fluctuations. It also provides a summary of the models used to predict key water quality variables. Section 2 gives a general overview of the utility and shortcomings of water quality models, with the goal of establishing key criteria for assessing the successes of models developed by the Northern River Basins Study (NRBS). Section 3 summarizes key findings of the NRBS models and evaluates the results against criteria outlined in section 2. Section 4 presents a series of recommendations for modelling dissolved oxygen, transport and fate of contaminants, and distribution of contaminants in the food chain, along with strategic suggestions for future work.

This book was released on 1996-08 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a study to construct and calibrate a steady-state food chain model to simulate the uptake and bioaccumulation of selected organic chemicals, with different physical and chemical properties, in the mountain whitefish, longnose sucker, and northern pike food web of the Athabasca River. The model is based on the WASP 14, Thomann-Connolly and Gobas food chain models. The modelling effort involved review and interpretation of sediment transport dynamics, contaminant distribution and concentration in sediment, water, and biota, and the refinement of the existing models. Results are presented from model simulations and compared to observed concentrations of such compounds as furans, resin acids, and chlorinated phenolics. The appendix includes a discussion of food chain modelling theory and its application to the present study.

Book excerpt: The aim of this report is to assess the sources of nitrogen and phosphorus to the Athabasca and Wapiti/Smoky rivers and evaluate the need to consider groundwater contributions when undertaking simulation modelling of chemical parameters of the Athabasca River during winter. To address the first objective, longitudinal trends in nitrogen and phosphorus were examined for each river system in relation to point source inputs and the contributions of anthropogenic point sources and agricultural activity in the rivers' nutrient loads were quantified. The importance of groundwater during winter was assessed by examining hydrologic mass balances and changes in dominant ion proportions. Results are presented of analyses of long-term values of nutrients from ten sites on the Athabasca and three sites on the Wapiti/Smoky rivers.

Book excerpt: Report to the federal ministers of Environment and Indian & Northern Affairs, Alberta's Minister of Environmental Protection, and NWT's Minister of Renewable Resources. Summarises the main scientific findings of the Northern River Basins Study, which was established to examine the relationship between industrial, municipal, agricultural, and other development and the Peace, Athabasca, and Slave River basins. Reviews the characteristics of the northern river basins and their peoples, the organisation of the Study, and major findings in the areas of environmental overview, use of aquatic resources, traditional knowledge, flow regulation, fish distribution and habitat, nutrients, dissolved oxygen, contaminants, drinking water, ecosystem health, modelling, human health, and cumulative effects. Recommendations by the Study Board, First Nations, and scientific advisors regarding such issues as basin management, monitoring, research, public participation, and a successor organisation are then presented. Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.

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 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report describes a two-dimensional contamminant fate and transport model and its application to the lower Athabasca River. This is one of the major deliverables of a multi-year project funded by the Interdepartmental Panel on Energy R&D (PERD) and Environment Canada to study the aquatic impact of oil sands and heavy oil operations in northeastern Alberta. The Athabasca tar sands contain a substantial part of Canada's oil supply. A number of nitrogen-, and sulphur-PAC's (polycyclic aromatic compounds) as well as their alkyl derivatives have been identified in tar sands plants process streams and emissions. Some of these PAC's are known mutagens and carcinogens. The fate and persistence of these chemicals downstream of tar sands plants on the Athabasca River have been examined using a combination of field and laboratory data collection coupled with computer simulation modelling. The model, ATHMOD2, is expected to be used in future enviromnental impact assessments which are required as a result of industry expansion. It can easily be applied to other toxic substances and rivers to consider continuous and single spill discharges where incomplete mixing required two-dirnensional analysis. It has been designed to operate within the Windows environment and has a user friendly input interface coupled with sophisticated model output visualization features"--Management perspective.
