Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Water temperature is a key physical habitat determinant in lotic ecosystems as it influences many physical, chemical and biological properties of rivers. Hence, a good understanding of the thermal regime of rivers is essential for effective management of water and fisheries resources. This study deals with the modeling of hourly stream watertemperature using a deterministic model, an equilibrium temperature model and an artificial neural network model. The water temperature models were applied on two thermally different streams, namely, the Little Southwest Miramichi River (LSWM) and Catamaran Brook (Cat Bk) in New Brunswick, Canada. The deterministic model calculated the different heat fluxes at the water surface and from the streambed, using different hydrometeorological conditions. Results showed that microclimate data are essential in making accurate estimates of the surface heat fluxes. Results also showed that for larger river systems, the surface heat fluxes were generally the dominant component of the heat budget with a correspondingly smaller contribution from the streambed (90%). As watercourses became smaller and as groundwater contribution became more significant, the streambed contribution became important (20%). The equilibrium temperature model is a simplified version of the deterministic model where the total heat flux at the surface is assumed to be proportional to the difference between the water temperature and the equilibrium temperature. The poor model performance compared to the other models developed in this study suggested that the air and equilibrium temperature did not reflect entirely the total heat flux at an hourly scale.

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

Download or read book Water Quality Modeling written by Steven C. McCutcheon and published by CRC Press. This book was released on 1990-01-05 with total page 348 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.
