Download or read book Assessment and Validation of Modelling Under ice Dissolved Oxygen Using DOSTOC Athabasca River 1988 to 1994 written by Patricia A. Chambers and published by . This book was released on 1996 with total page 220 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea level do not lie within a drainage basin. Even points distant from the nearest channel are likely to be influenced by that channel. Tectonic uplift raises rock thousands of meters above sea level. Precipitation falling on the uplifted terrain concentrates into channels that carry sediment downward to the oceans and influence the steepness of adjacent hill slopes by governing the rate at which the landscape incises. Rivers migrate laterally across lowlands, creating a complex topography of terraces, floodplain wetlands and channels. Subtle differences in elevation, grain size, and soil moisture across this topography control the movement of ground water and the distribution of plants and animals. Rivers in the Landscape, Second Edition, emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form. The book is suitable for use as a course text or a general reference on rivers. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, Rivers in the Landscape is designed to: emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; provide a concise summary of the current state of knowledge for physical process and form in rivers; reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references.

This book was released on 1996 with total page 112 pages. Available in PDF, EPUB and Kindle. 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.
