Download or read book Evaluation of Aeration circulation as a Lake Restoration Technique written by Robert A. Pastorok and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial circulation and hypolimnetic aeration are management techniques for oxygenating eutrophic lakes subject to water quality problems, algal blooms, and fishkills. Artificial circulation is achieved by injecting diffused air into lower waters, by mechanical pumping of water from one depth stratum to another, or by inducing turbulence at the surface using large axial-flow pumps. In contrast, hypolimnetic aeration by air or oxygen injection affects primarily bottom waters. In some instances low dissolved oxygen concentrations persist in the metalimnion. In general, both methods lower the concentrations of reduced compounds in lake waters, providing benefits for water supply systems. Aeration may cause supersaturation of nitrogen gas, thereby raising the potential danger of gas bubble disease in downstream fishes.

Download or read book Restoration and Management of Lakes and Reservoirs Third Edition written by G. Dennis Cooke and published by CRC Press. This book was released on 2016-04-19 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been more than ten years since the last edition of the bestselling Restoration and Management of Lakes and Reservoirs. In that time, lake and reservoir management and restoration technologies have evolved and an enhanced version of this standard resource is long overdue. Completely revised and updated, the third edition continues the tradition of providing comprehensive coverage of the chemical, physical, and biological processes of eutrophication and its control. The authors describe the eutrophication process, outline methods for developing a pre-management and restoration diagnosis-feasibility study, and provide detailed descriptions of scientifically sound management and restoration methods. See what’s new in the Third Edition: • New chapters on aquatic plant ecology and management • Emphasis on freshwater availability • A regional framework for water quality attainment • Methods of lake and reservoir restoration and management • Updates or revisions to all other chapters The book features in-depth discussions of techniques used to manage eutrophication in standing water bodies, procedures for using these techniques, the principles involved, and successes and failures through a selection of case studies and cost analyses. Each chapter includes an introduction to the scientific basis of the problem, a description of the methods and procedures, and presents several case histories. Potential negative impacts and costs, where known, are described. A useful classroom text, reference manual, and general guide, this is the text against which all other resources in this field are measured.

This book was released on 2012-12-02 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ispra Course on Ecological Assessment of Environmental Degradation, Pollution and Recovery'' was structured according to the following topics: (a) terrestrial and aquatic ecosystem concept; (b) structure, functions and evolution of the ecosystem in relation to the natural and anthropogenic influences, and (c) concept of stress, assessment and restoration of terrestrial and aquatic ecosystems. These general concepts were developed in a series of lectures presented by well-known experts in their specific fields, taking into account the ecological principles and environmental management. For the various aspects of the environmental problems, the state-of-the-art, the principles of restoration techniques, the results obtained by their application and the research needs to acquire a better knowledge of the ecological processes, were discussed. The lectures were illustrated by several case studies concerning forests, lakes, reservoirs, rivers, soil and the interrelations between air and terrestrial and aquatic ecosystems.This book contains the lectures presented at the course, reviewed by the authors, and complemented throughout with numerous figures and tables.

Download or read book Alternatives in Regulated River Management written by James A. Gore and published by CRC Press. This book was released on 2018-01-18 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.

Download or read book Lake and Reservoir Restoration written by G. Dennis Cooke and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.
