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.

Download or read book Dissolved Oxygen Conditions and Fish Requirements in the Athabasca Peace and Slave Rivers written by Patricia A. Chambers and published by . This book was released on 1996 with total page 112 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.
Download or read book Assessment and Validation of Modelling Under ice Dissolved Oxygen Using DOSTOC Athabasca River 1988 to 1994 written by Patricia A. Chambers and published by . This book was released on 1996 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to examine the existing model approach and to make recommendations for improved modelling of under-ice dissolved oxygen (DO) concentrations in the Athabasca River. Previous modelling efforts have involved using the DO simulation model DOSTOC, but discrepancies between observed and predicted DO concentrations for 1992 and 1993 highlighted the needs for a review and assessment of the modelling approaches used. This report reviews the structure of the DOSTOC model and input data used for modelling, then describes a stochastic run of the model using the best available values for input data and process rates, including revised rates and ratios for converting five-day biological oxygen demand (BOD) values to ultimate BOD values, measured values for sediment oxygen demand and sedimentation, and a temperature correction for pulp mill BOD decay rates. Simulation results indicate whether the model could predict DO for 1990-94 winters. Regression equations were also developed relating DO concentration to river distance.

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: The purpose of this study was to determine the potential for off-flavour tainting of water and/or fish in the Athabasca River by compounds discharged from pulp mills. Three different analytical methods commonly used in monitoring for the presence of odorous compounds in water supplies are described and results are presented: odour characterization by a trained flavour profile panel; olfactory gas chromatography; and gas chromatography/mass spectroscopy. The usefulness of each method in providing different types of information is noted. The results are compared with those of an earlier survey to indicate the impact of combined effluents at Hinton on the odour of the Athabasca River.
