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 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.

Download or read book Reservoir Fish Habitat Management written by L.E, Miranda and published by Lightning Press. This book was released on 2017-03-01 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is organized into an introduction and 13 sections. Section 1 is based on a nationwide survey of reservoir habitats completed by the Reservoir Fisheries Habitat Partnership (RFHP). The RFHP canvassed agency professionals about various aspects of reservoir fish habitat degradation, and identified 12 comprehensive factors that captured most degradation. The sections developed in this document parallel these 12 factors to identify management practices that address the perceived degradation. Most sections are organized similarly: background information about the degradation factor is followed by a listing of alternative management practices. Deciding on appropriate management action can be complex because there are often several options for addressing degradation problems. Different options may have different cost, effectiveness, and consequences. A simplified decision model to choose among management options is suggested in section 12. Habitat management often goes far beyond the manpower available to agencies involved in reservoir habitat management, so suggestions on working with stakeholders are included in section 13. Ballpark costs of reservoir fish habitat management practices are given in the Appendix.

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.
