Contribution of Industrial, Municipal, Agricultural and Groundwater Sources to Nutrient Export, Athabasca, Wapiti and Smoky Rivers, 1980-1993


Book Description

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.




Technical Reports of the Northern River Basins Study by Subject and Geographical Area Studied


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.




Canadian Guidance Framework for the Management of Phosphorus in Freshwater Systems


Book Description

This document presents a guidance framework for the management of phosphorus in freshwater systems. The introduction reviews the development & validation of this framework. Chapter 2 presents a review of the scientific literature on phosphorus in the aquatic environment, including properties, sources, fate, sediment interactions, parameters affecting phosphorus availability, trophic status, & effects on organisms. Chapter 3 examines a number of approaches used by other jurisdictions for setting phosphorus guidelines. Chapter 4 outlines the proposed framework-based approach for phosphorus management in which water bodies are marked for further assessment by comparing their trophic status to predefined ranges of phosphorus concentration. Chapter 5 summarizes some of the recommended assessment options currently use in Canada & other jurisdictions. Chapter 6 reviews management options that can be considered once the phosphorus concentrations have been assessed & compared to original goals for the water body. The final two chapters present case studies of implementation of this framework at Lake Simcoe in Ontario and at Kodiak Lake, Northwest Territories.

Tools of the Trade


Book Description

Tools of the Trade: Methods, Techniques and Innovative Approaches in Archaeology presents a collection of academic papers from the 2005 Chacmool archaeological conference, which includes a wide range of contributions from international archaeologists, senior professors, and students alike. Each chapter focuses on the discussion and application of unique and innovative 'tools' for archaeological analysis and interpretation, including micro- and macro-botanical analysis, experimental study, off-site survey, lithic use-wear, ceramic petrography, DNA analysis, cha ne op ratoire, space syntax, and Geographic Information Systems. As a collective volume, Tools of the Trade: Methods, Techniques and Innovative Approaches in Archaeology also covers an impressive diversity of geographic regions and time periods, such as Precolumbian Mesoamerica, Plio-Pleistocene Africa, prehistoric and historic North America, and ancient Polynesia. Finally, this volume provides a somewhat introspective look at the origins of tool use, technological development, and the means by which we have become the only species to ask the questions: What does it mean to be us and how can we find out?
