Available in PDF, EPUB and Kindle. Book excerpt: For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

Download or read book Water Quality Modeling written by Steven C. McCutcheon and published by CRC Press. This book was released on 2024-11-01 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating work is divided into two main sections. Part I reviews the basic principles of water movement in channels and the mass balance approach common to most models. It also covers the practical usefulness, model peer review, and guidance on model selection and calibration. Part II discusses flow simulation and prediction of time of travel, dye tracing and mixing, heat balance and temperature modeling, and reaeration and volatilization. This interesting, easy-to-read volume includes comprehensive reviews for the use of fluorescent water tracing dyes, longitudinal dispersion, evaporation and wind speed functions, prediction of saturation concentrations of dissolved oxygen, and reaeration coefficients. This book furnishes the reader with appendices which provide a synopsis of available computer models and gives a comprehensive listing of methods used to measure flow rates in rivers, tributaries, and pipes and channels introducing wastewaters into streams. This volume is a valuable, indispensable reference for all researchers, instructors, students in advanced environmental modeling courses, and practicing engineers.
