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.
