Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results using a revised model simulating the fate of contaminants in the Athabasca River. The revised fate model allows predictive sediment transport simulation within the WASP4 model framework, predicts resuspension from hydraulic information supplied by WASP4 and from user-supplied sediment characteristics, and can be applied to different flow conditions without having to re-describe sediment transport rates. Several simulations were run using input files from the original model calibration. Program listings of subroutines are included.

This book was released on 1996-08 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a study to construct and calibrate a steady-state food chain model to simulate the uptake and bioaccumulation of selected organic chemicals, with different physical and chemical properties, in the mountain whitefish, longnose sucker, and northern pike food web of the Athabasca River. The model is based on the WASP 14, Thomann-Connolly and Gobas food chain models. The modelling effort involved review and interpretation of sediment transport dynamics, contaminant distribution and concentration in sediment, water, and biota, and the refinement of the existing models. Results are presented from model simulations and compared to observed concentrations of such compounds as furans, resin acids, and chlorinated phenolics. The appendix includes a discussion of food chain modelling theory and its application to the present study.

This book was released on 1997 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarizes the major modelling projects undertaken to model water quality in the Peace, Athabasca, and Slave river systems. The first section describes the scope of the problem of modelling water quality in large complex systems that are relatively oligotrophic, located at relatively high altitudes, and experience highly seasonal environmental fluctuations. It also provides a summary of the models used to predict key water quality variables. Section 2 gives a general overview of the utility and shortcomings of water quality models, with the goal of establishing key criteria for assessing the successes of models developed by the Northern River Basins Study (NRBS). Section 3 summarizes key findings of the NRBS models and evaluates the results against criteria outlined in section 2. Section 4 presents a series of recommendations for modelling dissolved oxygen, transport and fate of contaminants, and distribution of contaminants in the food chain, along with strategic suggestions for future work.

Book excerpt: Ecological Model Types brings an understanding on how to quantitatively analyze complex and dynamic ecosystems with the tools available today. Ecosystem studies widely use the notions of order, complexity, randomness, and organization, and are used interchangeably in literature, which causes much confusion. Better models synthesize our knowledge on ecosystems and their environmental problems, in contrast to statistical analysis, which only reveal the relationships between the data. This book brings together experts on ecological models to create a definitive work on how to understand our complex Earth. - Bridges the gap between statistical analysis and synthesis of data, enhancing our understanding about ecosystems and their environmental problems - Helps readers understand complex ecosystems by walking through the best modeling options to analyze and predict environmental effects - Provides a detailed review of 14 model types, covering the breadth of options available for analysis at this time

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.

This book was released on 1995 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a study that collected and prepared fish from 23 sites along the Peace, Athabasca, and Slave river drainages in order to conduct physical, physiological, contaminant, and biophysical analyses. The primary fish species targeted for collection and analysis was burbot, used as a sentinel species for monitoring contaminants in northern waters because of its wide distribution, ease of catching, place at the top of the aquatic food chain, and large liver which can bioaccumulate organic compounds. Other species collected were northern pike, longnose sucker, and flathead chub. Specific analyses included gross pathology, metals, liver mixed function oxygenase induction, sex steroids and gonad morphology, retinols, metallothioneins, and basic life history information. Fish were also examined externally and internally for gross pathological abnormalities and deformities. Appendices contain descriptions of fish collection and handling protocols, as well as detailed data.
