Download or read book Winter Under ice Tracer Dye Studies Time of Travel and Mixing Characteristics written by Northwest Hydraulic Consultants and published by The Study. This book was released on 1994 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the hydraulic characteristics of rivers is necessary to understand how effluents and their contaminants are mixed and transported, and where they are deposited in rivers. To properly model the transport of contaminants and pollutants within freshwater systems, the mixing or dispersion characteristics must be established. The tracer dye study focused on the calculation of mixing coefficients and travel times using field dye tests on the Peace River between Shaftsbury Ferry and Notikewan River. The test was completed under ice covered conditions in February and March 1993, the period most critical for potential impacts on the aquatic ecosystem.

Available in PDF, EPUB and Kindle. 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.

This book was released on 1997 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lists Northern River Basins Study technical reports by issue number, subject, and geographic area studied. Subject areas used to classify the reports are: hydrology/hydraulics, nutrients/dissolved oxygen, contaminants, food chain, drinking water, other uses, traditional knowledge, and synthesis and modelling. Ten geographic divisions are used: three each for the Athabasca and Peace Rivers, and one each of the Wapiti/Smoky rivers, Peace-Athabasca Delta, Lake Athabasca, and Rivière des Rochers/Slave River.

Download or read book Contaminant Fate Modelling Athabasca Wapiti and Smoky Rivers written by Golder Associates and published by . This book was released on 1996 with total page 482 pages. 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.
