Lake and Reservoir Restoration


Book Description

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.










Landscape as Infrastructure


Book Description

As ecology becomes the new engineering, the projection of landscape as infrastructure—the contemporary alignment of the disciplines of landscape architecture, civil engineering, and urban planning— has become pressing. Predominant challenges facing urban regions and territories today—including shifting climates, material flows, and population mobilities, are addressed and strategized here. Responding to the under-performance of master planning and over-exertion of technological systems at the end of twentieth century, this book argues for the strategic design of "infrastructural ecologies," describing a synthetic landscape of living, biophysical systems that operate as urban infrastructures to shape and direct the future of urban economies and cultures into the 21st century. Pierre Bélanger is Associate Professor of Landscape Architecture and Co-Director of the Master in Design Studies Program at Harvard University’s Graduate School of Design. As part of the Department of Landscape Architecture and the Advansed Studies Program, Bélanger teaches and coordinates graduate courses on the convergence of ecology, infrastructure and urbanism in the interrelated fields of design, planning and engineering. Dr. Bélanger is author of the 35th edition of the Pamphlet Architecture Series from Princeton Architectural Press, GOING LIVE: from States to Systems (pa35.net), co-editor with Jennifer Sigler of the 39th issue of Harvard Design Magazine, Wet Matter, and co-author of the forthcoming volume ECOLOGIES OF POWER: Mapping Military Geographies & Logistical Landscapes of the U.S. Department of Defense. As a landscape architect and urbanist, he is the recipient of the 2008 Canada Prix de Rome in Architecture and the Curator for the Canada Pavilion ad Canadian Exhibition, "EXTRACTION," at the 2016 Venice Architecture Biennale (extraction.ca).




The Ecology and Management of Wetlands


Book Description

This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
