Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book The 1993 Flood on the Mississippi River in Illinois written by Nani G. Bhowmik and published by . This book was released on 1994 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lessons learned from this flood focus on the performance of the levees, governmental responses, the effects of flood fighting, change in stages due to levee breaches, flood modeling, and the lack of information dissemination to the public on the technical aspects of the flood. These lessons point out information gaps and the need for research in the areas of hydraulics and hydrology, meteorology, sediment transport and sedimentation, surface and ground-water interactions, water quality, and levees. The report presents a comprehensive summary of the 1993 flood as far as climate, hydrology, and hydraulics are concerned.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Download or read book The Control of Nature written by John McPhee and published by Farrar, Straus and Giroux. This book was released on 2011-04-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: While John McPhee was working on his previous book, Rising from the Plains, he happened to walk by the engineering building at the University of Wyoming, where words etched in limestone said: "Strive on--the control of Nature is won, not given." In the morning sunlight, that central phrase--"the control of nature"--seemed to sparkle with unintended ambiguity. Bilateral, symmetrical, it could with equal speed travel in opposite directions. For some years, he had been planning a book about places in the world where people have been engaged in all-out battles with nature, about (in the words of the book itself) "any struggle against natural forces--heroic or venal, rash or well advised--when human beings conscript themselves to fight against the earth, to take what is not given, to rout the destroying enemy, to surround the base of Mt. Olympus demanding and expecting the surrender of the gods." His interest had first been sparked when he went into the Atchafalaya--the largest river swamp in North America--and had learned that virtually all of its waters were metered and rationed by a U.S. Army Corps of Engineers' project called Old River Control. In the natural cycles of the Mississippi's deltaic plain, the time had come for the Mississippi to change course, to shift its mouth more than a hundred miles and go down the Atchafalaya, one of its distributary branches. The United States could not afford that--for New Orleans, Baton Rouge, and all the industries that lie between would be cut off from river commerce with the rest of the nation. At a place called Old River, the Corps therefore had built a great fortress--part dam, part valve--to restrain the flow of the Atchafalaya and compel the Mississippi to stay where it is. In Iceland, in 1973, an island split open without warning and huge volumes of lava began moving in the direction of a harbor scarcely half a mile away. It was not only Iceland's premier fishing port (accounting for a large percentage of Iceland's export economy) but it was also the only harbor along the nation's southern coast. As the lava threatened to fill the harbor and wipe it out, a physicist named Thorbjorn Sigurgeirsson suggested a way to fight against the flowing red rock--initiating an all-out endeavor unique in human history. On the big island of Hawaii, one of the world's two must eruptive hot spots, people are not unmindful of the Icelandic example. McPhee went to Hawaii to talk with them and to walk beside the edges of a molten lake and incandescent rivers. Some of the more expensive real estate in Los Angeles is up against mountains that are rising and disintegrating as rapidly as any in the world. After a complex coincidence of natural events, boulders will flow out of these mountains like fish eggs, mixed with mud, sand, and smaller rocks in a cascading mass known as debris flow. Plucking up trees and cars, bursting through doors and windows, filling up houses to their eaves, debris flows threaten the lives of people living in and near Los Angeles' famous canyons. At extraordinary expense the city has built a hundred and fifty stadium-like basins in a daring effort to catch the debris. Taking us deep into these contested territories, McPhee details the strategies and tactics through which people attempt to control nature. Most striking in his vivid depiction of the main contestants: nature in complex and awesome guises, and those who would attempt to wrest control from her--stubborn, often ingenious, and always arresting characters.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to present basic principles used in the design and construction of earth levees. The term levee as used herein is defined as an embankment whose primary purpose is to furnish flood protection from seasonal high water and which is therefore subject to water loading for periods of only a few days or weeks a year. Embankments that are subject to water loading for prolonged periods (longer than normal flood protection requirements) or permanently should be designed in accordance with earth dam criteria rather than the levee criteria given herein. Even though levees are similar to small earth dams they differ from earth dams in the following important respects: (a) a levee embankment may become saturated for only a short period of time beyond the limit of capillary saturation, (b) levee alignment is dictated primarily by flood protection requirements, which often results in construction on poor foundations, and (c) borrow is generally obtained from shallow pits or from channels excavated adjacent to the levee, which produce fill material that is often heterogeneous and far from ideal. Selection of the levee section is often based on the properties of the poorest material that must be used.
