This book was released on 1986 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a literature review of reservior internal mixing processes, in which general transport processes, reservoir mixing processes and their effect on water quality, and one-dimensional predictive techniques and computer algorithms are presented and analyzed. The historical development of the recommended predictive techniques, including the assumptions, limitations, and advantages of the techniques used in the development, is also documented. The recommended one-dimensional mixing algorithm is generalized with respect to CE reservoirs and is not constrained by extensive data requirements nor limited in the mixing processes considered. The algorithm includes all major mixing processes in order to predict changes in the reservoir's mixing regime resulting from changes in hydrometeorological conditions and project operation. The recommended algorithms was used to simulate the thermal structure of over 15 reservoirs and lakes of varying geographical locations, size hydrometeorological regime, and operational configurations. The recommendations for the mixing algorithm are the opinions of the authors, and all phases of it are not necessary incorporated in the current one-dimensional CE reservoir model (CE- QUAL-R1).

Available in PDF, EPUB and Kindle. Book excerpt: Since tributary inflows are usually the major sources of nutrients and other materials affecting reservoir water quality, techniques for predicting the characteristics of density currents can help the U.S. Army Corps of Engineers regulate the quality of reservoir and release waters. This report provides a literature review of density current predictive techniques, in which field observations, factors inhibiting prediction, and water quality implications are discussed and predictive techniques are presented and analyzed. Specific equations for predicting plunge point location, initial mixing, interflow thickness, propagation speed, and underflow entrainment are developed and compared, and certain ones recommended for use. A mathematical method for determining water density, example computations illustrating how to use the recommended predictive equations, and a relevant computer algorithm to be used in a one-dimensional water quality model (e.g., CE-QUAL-R1) are presented in appendices.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.

Download or read book Reservoir Compartmentalization written by S. J. Jolley and published by Geological Society of London. This book was released on 2010 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Reservoir compartmentalization - the segregation of a petroleum accumulation into a number of individual fluid/pressure compartments - controls the volume of moveable oil or gas that might be connected to any given well drilled in a field, and consequently impacts 'booking' of reserves and operational profitability. This is a general feature of modern exploration and production portfolios, and has driven major developments in geoscience, engineering and related technology. Given that compartmentalization is a consequence of many factors, an integrated subsurface approach is required to better understand and predict compartmentalization behaviour, and to minimize the risk of it occurring unexpectedly. This volume reviews our current understanding and ability to model compartmentalization. It highlights the necessity for effective specialist discipline integration, and the value of learning from operational experience in: detection and monitoring of compartmentalization; stratigraphic and mixed-mode compartmentalization; and fault-dominated compartmentalization"--Page 4 of cover.
