Sediment Dynamics and Implications for Sediment-associated Contaminants in the Peace, Athabasca and Slave River Basins


Book Description

Examines the mechanisms of natural riverine sediment production in the Northern River Basins Study area, together with the routine data for suspended sediment in the area's rivers, as background for the examination of sediment-associated contaminants. Topics examined include: the causative mechanisms and boundary conditions affecting the sediment regime, including area topography, geology, and hydrology; availability and adequacy of data on suspended sediments in the area; time trends of fluvial suspended sediment dynamics on a seasonal (open water and ice regime) and annual basis, over the long term, and in critical events; sediment sources, pathways, and fates, and sediment dynamics at basin-wide, reach, and site levels; sediment quality, including sediment-associated characteristics of pulp mill effluents and sediment-contaminant relationships; and implications for sediment-associated contaminants. Recommendations are made for monitoring and assessment of the sediment component of the area's ecosystem.







Reclaimed Land


Book Description

This text is the first in a series that sets out to highlight work being done to restore land damaged by human activity, and to minimize further damage. Each volume explores a land management problem from a scientific perspective. This work investigates surface coal mining and its effects.







Alberta’s Lower Athabasca Basin


Book Description

Over the past two decades, the oil sands region of northeastern Alberta has been the site of unprecedented levels of development. Alberta's Lower Athabasca Basin tells a fascinating story of how a catastrophic ice age flood left behind a unique landscape in the Lower Athabasca Basin, one that made deposits of bitumen available for surface mining. Less well known is the discovery that this flood also produced an environment that supported perhaps the most intensive use of boreal forest resources by prehistoric Native people yet recognized in Canada. Studies undertaken to meet the conservation requirements of the Alberta Historical Resources Act have yielded a rich and varied record of prehistoric habitation and activity in the oil sands area. Evidence from between 9,500 and 5,000 years ago—the result of several major excavations—has confirmed extensive human use of the region’s resources, while important contextual information provided by key geological and palaeoenvironmental studies has deepened our understanding of how the region’s early inhabitants interacted with the landscape. Touching on various elements of this rich environmental and archaeological record, the contributors to this volume use the evidence gained through research and compliance studies to offer new insights into human and natural history. They also examine the challenges of managing this irreplaceable heritage resource in the face of ongoing development. Contributors: Alwynne Beaudoin, Angela Younie, Brian O.K.

Rivers of North America


Book Description

Rivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. - Provides a single source of information on North America's major rivers - Features authoritative information on more than 200 rivers from regional specialists - Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system - Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

Ecotoxicology of Suspended and Bottom Sediments, Athabasca, Smoky and Peace Rivers, June, 1995


Book Description

The objectives of this project were to re-examine sediment toxicity at sites sampled previously on the Athabasca River, including sites in the oil sands area, and to conduct toxicity testing on a number of additional sites on the Athabasca, Smoky, and Peace rivers. Investigators tested suspended and bottom sediment samples using four species of freshwater benthic invertebrates in chronic exposure studies. Endpoints measured included survival, growth (amphipod, chironomid, and mayfly) and reproduction (oligochaete worm). Test results were compared with those using standard reference sediment samples for biological quality assurance.
