Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Human history has often been described as a progressive relinquishment from environmental constraints. Now, it seems, we have come full circle. The ecological irrationalities associated with industrial societies have a lengthy history, and our purpose in the proposed book is not to catalogue this litany of wrongs. Rather, this book is about political responses to global environmental crisis at a crucial turning point in history, by focusing on the political discourses surrounding the tar sands in Alberta, Canada.

Book Description
This book aims to cover the following general topics: development and assessment of theories for evaluating commodity risk; the role of derivative securities in managing commodity risk; and, an assessment of the actual management of commodity risk in specific situations. The primary contribution of the book is the explicit development of the often overlooked connection between risk management and speculation. The central theme is to demonstrate that commodity risk management decisions require an in depth understanding of speculative strategies. To this end, this book aims to provide a unified treatment of important concepts and techniques that are useful in applying derivative securities in the management of risk arising in commodity markets.
