Available in PDF, EPUB and Kindle. Book excerpt: Darcy's Law has been used by civil engineers for problems involving saturated flow, especially for the design of water retention dams. There has been a class of problems that deal with partially saturated leakage from waste impoundments has evolved. This can pose environmental hazards if the leachate is toxic, and is not collected and treated.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation was to improve current design procedures for predicting earth pressures on rigid (concrete) conduits and retaining walls of the type frequently built by the U.S. Army Corps of Engineers. A comprehensive literature review was made to determine the generally accepted design methods (in addition to those of the Corps of Engineers) for predicting earth pressures on rigid conduits and retaining walls. Finite-element computer studies were performed to investigate the nature of earth pressures on buried conduits. Analytical comparisons were made of the many theories available for predicting earth pressures on retaining walls. Several suggested improvements to present Corps of Engineers design methods resulted from this study. The recommended procedures were compared with earth pressure data from several Corps of Engineer projects. In general, the suggested changes resulted in more accurate predictions of earth pressures on rigid conduits and retaining walls than are calculated by the present methods. This investigation has indicated several areas of inadequate present knowledge that could warrant further field and/or analytical study.

Download or read book Impacts of Large Dams A Global Assessment written by Cecilia Tortajada and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

This book was released on 2011-12-07 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-published with UNESCO A product of the UNESCO-IHP project on Water and Cultural Diversity, this book represents an effort to examine the complex role water plays as a force in sustaining, maintaining, and threatening the viability of culturally diverse peoples. It is argued that water is a fundamental human need, a human right, and a core sustaining element in biodiversity and cultural diversity. The core concepts utilized in this book draw upon a larger trend in sustainability science, a recognition of the synergism and analytical potential in utilizing a coupled biological and social systems analysis, as the functioning viability of nature is both sustained and threatened by humans.

Download or read book River Hydraulics written by U. S. Army Corps of Engineers and published by . This book was released on 2004-12-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual presents the techniques and procedures that are used to investigate and resolve river engineering and analysis issues and the associated data requirements. It also provides guidance for the selection of appropriate methods to be used for planning and conducting the studies. Documented herein are past experiences that provide valuable information for detecting and avoiding problems in planning, performing, and reporting future studies. The resolution of river hydraulics issues always requires prediction of one or more flow parameters; be it stage (i.e., water surface elevation), velocity, or rate of sediment transport. This manual presents pragmatic methods for obtaining data and performing the necessary computations; it also provides guidance for determining the components of various types of studies.

Download or read book Archaeological Semiotics written by Robert W. Preucel and published by John Wiley & Sons. This book was released on 2010-04-26 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary book examines archaeology’s engagement with semiotics, from its early structuralist beginnings to its more recent Peircian encounters. It represents the first sustained engagement with Peircian semiotics in archaeology, as well as the first discussion of how pragmatic anthropology articulates with anthropological archaeology. Its central thesis is that archaeology is a distinctive kind of semiotic enterprise; one devoted to giving meaning to the past in the present through the study of materiality. It compliments standard studies of linguistics and reformulates contemporary theories of material culture. Providing an introduction to Saussure and a review of his legacy across structural, symbolic, and cognitive anthropology, Preucel goes on to present the Peircian alternative and highlights its influence on pragmatic anthropology. Of special interest are the discussions of the interrelations of structuralism and processual archaeology, poststructuralism and postprocessual archaeologies, and cognitive science and cognitive archaeology. The author offers two original case studies demonstrating how material culture pragmatically mediates social relations- one focusing on the aftermath of the Pueblo Revolt from 1680-1694 and the other on the New England utopian community of Brook Farm from 1842-1846. Throughout his analysis, Preucel emphasizes the close links between archaeology and other social sciences. But he also contends that archaeology, by virtue of the powerful ideological character of the past, can open up new spaces for discourse and dialogue about meaning, and, in the process, make a valuable contribution to contemporary semiotics.
