Wetland Drainage, Restoration, and Repair


Book Description

Wetlands are a vital part of the landscape and ecology of the United States, providing food and shelter for species ranging from the beautiful wood duck to the tiny fairy shrimp. These areas provide critical habitat for fish and wildlife, protect communities from flooding, and recharge groundwater supplies—yet they continue to be destroyed at an alarming rate. A detailed analysis of wetlands management, Wetland Drainage, Restoration, and Repair is a comprehensive guide to the past, present, and future of wetland recovery in the United States. The book includes a historical overview of wetland destruction and repair over the past two hundred years and also serves as a unique resource for anyone, from novice to engineer, interested in the process of wetland restoration. Author Thomas R. Biebighauser draws from his own vast experience in building and repairing more than 950 wetlands across North America. Included are numerous photographs and case studies that highlight successes of past projects. Detailed, step-by-step instructions guide the reader through the planning and implementation of each restoration action. Biebighauser also provides a number of effective strategies for initiating and improving funding for wetlands programs. Wetland Drainage, Restoration, and Repair is essential reading for all who care about and for these important ecosystems.

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.




Spaces Speak, Are You Listening?


Book Description

How we experience space by listening: the concepts of aural architecture, with examples ranging from Gothic cathedrals to surround sound home theater. We experience spaces not only by seeing but also by listening. We can navigate a room in the dark, and "hear" the emptiness of a house without furniture. Our experience of music in a concert hall depends on whether we sit in the front row or under the balcony. The unique acoustics of religious spaces acquire symbolic meaning. Social relationships are strongly influenced by the way that space changes sound. In Spaces Speak, Are You Listening?, Barry Blesser and Linda-Ruth Salter examine auditory spatial awareness: experiencing space by attentive listening. Every environment has an aural architecture.The audible attributes of physical space have always contributed to the fabric of human culture, as demonstrated by prehistoric multimedia cave paintings, classical Greek open-air theaters, Gothic cathedrals, acoustic geography of French villages, modern music reproduction, and virtual spaces in home theaters. Auditory spatial awareness is a prism that reveals a culture's attitudes toward hearing and space. Some listeners can learn to "see" objects with their ears, but even without training, we can all hear spatial geometry such as an open door or low ceiling. Integrating contributions from a wide range of disciplines—including architecture, music, acoustics, evolution, anthropology, cognitive psychology, audio engineering, and many others—Spaces Speak, Are You Listening? establishes the concepts and language of aural architecture. These concepts provide an interdisciplinary guide for anyone interested in gaining a better understanding of how space enhances our well-being. Aural architecture is not the exclusive domain of specialists. Accidentally or intentionally, we all function as aural architects.




Ambrose Bierce is Missing


Book Description

What constitutes historical truth is often subject to change. Through ingenious detection, the accepted wisdom of one generation may become the discredited legend of another—or vice versa. In this wide- ranging study of historical investigation, former detective Joe Nickell allows the reader to look over his shoulder as he demonstrates the use of varied techniques in solving some of the world's most perplexing mysteries. All the major categories of historical mystery are here—ancient riddles, biographical enigmas, hidden identity, "fakelore," questioned artifacts, suspect documents, lost texts, obscured sources, and scientific challenges. Each is then illustrated by a complete case from the author's own files. Nickell's investigation of the giant Nazca drawings in Peru, for example—thought by some to provide proof of ancient extraterrestrial visitations—uses innovative techniques to reveal a very different origin. Other cases concern the 1913 disappearance of writer and journalist Ambrose Bierce, the authenticity of the Shroud of Turin, the truth about the identity of John Demjanjuk ("Ivan the Terrible" to Polish death camp victims), the fate of a lost colonial American text, the authenticity of Abraham Lincoln's celebrated Bixby letter, and the apparent real-life model for a mysterious character in a novel by Nathaniel Hawthorne. In reaching his solutions, Nickell demonstrates a wide variety of investigative techniques—chemical and instrumental analyses, physical experimentation, a "psychological autopsy," forensic identification, archival research, linguistic analysis, folklore study, and many others. His highly readable book will intrigue the scholar and the history buff no less than the mystery lover.
