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.
Download or read book Contaminant Fate Modelling for the Athabasca River written by Golder Associates and published by The Study. This book was released on 1996 with total page 172 pages. 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.

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.

Download or read book Diffusion Models of Environmental Transport written by Bruce Choy and published by CRC Press. This book was released on 2017-12-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fate and transport models are critical components in the determination of the exposure to and risk from hazardous contaminants. Analytical models are preferable because they are generally more accessible, more reliable, and require fewer computational resources. Surprisingly, until today, only a limited number of analytical models have been accessible in the literature. Now, there is Diffusion Models of Environmental Transport, which provides more than 40 analytical models of diffusion and advective-diffusion in one, two, and three layer systems, subject to a wide range of boundary and initial conditions. This text illustrates applications to contaminant transport in sediments and soils, including porewater and vapor transport, and also provides Mathcad spreadsheets to aid in the use of these models. The authors supply complete details of the solutions to the models for those who wish for a deeper understanding. For others, who do not have the time or the need, the solutions themselves are ready to be picked up and used. Reible and Choy use their 20-plus years of cumulative experience to create a thorough exploration of fate and transport models. This comprehensive text furnishes an invaluable reference for students and environmental professionals.

Available in PDF, EPUB and Kindle. Book excerpt: River Flow 2022 includes the keynote lecture and contributed papers presented at River Flow 2022, the 11th International Conference on Fluvial Hydraulics (8-10 November 2022, Kingston and Ottawa, Canada; held virtually). River Flow 2022 provides an overview of the latest experimental, theoretical and computational findings on fundamental river flow and transport processes, river morphology and morphodynamics, while covering also issues related to the effects of hydraulic structures on flow regime, river morphology and ecology; sustainable river engineering practices (including stream restoration and re-naturalization); and effects of climate change including extreme flood events. The book presents the state-of-the-art in river research and engineering, and is aimed at academics and practitioners in hydraulics, hydrology and environmental engineering.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
