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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique collection of inter- and multidisciplinary studies on river systems. Rivers have been the prime source of sustenance since the advent of civilization and river systems often form the basis for agriculture, transport, water, and land for domestic, commercial, and industrial activities, fostering economic prosperity. A river basin is a basic geographical and climatological unit within which the vagaries of natural processes act and manifest themselves at different spatio-temporal scales. Even if compared side-by-side, no two river basins respond to natural processes in the same way and thus, it has long been recognized that each river basin is unique. Hence, any developmental activity or conservation effort has to be designed and implemented to match each unique river basin. With the burgeoning population and increasing dependency on natural resources, understanding and maintaining river systems has become increasingly important. This book provides a varied reference work on and unprecedented guidelines for conducting and implementing research on river basins, and for managing their ecological development.

Book excerpt: This publication, part of a series from the International Programme on Chemical Safety, evaluates the risk to human health and the environment posed by exposures to ethylene glycol, a clear, colourless liquid with a sweet taste but no odour. Estimated production capacity was 9.4 million tonnes in 1993, and release into the environment is mainly to the hydrosphere. The largest local release to surface waters would follow its use as a de-icer on airport runways and planes. On a world-wide basis, approximately two-thirds is used as a chemical intermediate, with a further one-quarter used as an antifreeze in engine coolants.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding groundwater recharge is essential for successful management of water resources and modeling fluid and contaminant transport within the subsurface. This book provides a critical evaluation of the theory and assumptions that underlie methods for estimating rates of groundwater recharge. Detailed explanations of the methods are provided - allowing readers to apply many of the techniques themselves without needing to consult additional references. Numerous practical examples highlight benefits and limitations of each method. Approximately 900 references allow advanced practitioners to pursue additional information on any method. For the first time, theoretical and practical considerations for selecting and applying methods for estimating groundwater recharge are covered in a single volume with uniform presentation. Hydrogeologists, water-resource specialists, civil and agricultural engineers, earth and environmental scientists and agronomists will benefit from this informative and practical book. It can serve as the primary text for a graduate-level course on groundwater recharge or as an adjunct text for courses on groundwater hydrology or hydrogeology. For the benefit of students and instructors, problem sets of varying difficulty are available at http://wwwbrr.cr.usgs.gov/projects/GW_Unsat/Recharge_Book/.
