This book was released on 1994 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management and design of natural channel systems may be defined as the process by which new or reconstructed stream channels and their associated flood plain riparian systems are designed to be naturally functional, stable, healthy, productive, and sustainable. This document is intended to provide an approach to natural channel management and design by identifying important functional ecological relationships between stream channels, their associated riparian and flood plain systems, and their watersheds. It provides a conceptual basis for natural channel systems, describes design principles, and also introduces a stream classification system that can be used in identifying often overlooked geomorphological principles and attributes of stream and valley systems. A case study design application and a glossary are included.

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software.

Download or read book Stream Channel Stability written by Joe C. Willis and published by . This book was released on 1981 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a stable alluvial channel, no net erosion or deposition of sediment occurs on the average. The sediment supply rate from upstream is balanced by capacity of the flow to transport the bed material. Any successful channel design must maintain this equilibrium or establish it for channel reaches that are not stable. Design relationships between the bed material transport capacity and the hydraulic variables of flow are based primarily on data from relatively small test channels. Reliable data for equilibrium transport of bed material by flows over about twenty cfs are not adequate to insure that data from small flumes can be extrapolated to prototype designs. An investigation was conducted in the 250-ft long test channel at the USDA Sedimentation Laboratory to obtain additional data on equilibrium transport by flows up to 150 cfs. Data on the transport rates, flow friction factors, and statistical properties of the bed forms were obtained. The results are presented as basic variable correlations with the controlled variables of the experiments, depth and discharge, along with attempts to generalize the relationships by similitude principles.

Download or read book Open Channel Flow written by Roland Jeppson and published by CRC Press. This book was released on 2010-11-09 with total page 1260 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatment of open channel flow, Open Channel Flow: Numerical Methods and Computer Applications starts with basic principles and gradually advances to complete problems involving systems of channels with branches, controls, and outflows/ inflows that require the simultaneous solutions of systems of nonlinear algebraic equations coupled with differential equations. The book includes a CD that contains a program that solves all types of simple open channel flow problems, the source programs described in the text, the executable elements of these programs, the TK-Solver and MathCad programs, and the equivalent MATLAB® scripts and functions. The book provides applied numerical methods in an appendix and also incorporates them as an integral component of the methodology in setting up and solving the governing equations. Packed with examples, the book includes problems at the end of each chapter that give readers experience in applying the principles and often expand upon the methodologies use in the text. The author uses Fortran as the software to supply the computer instruction but covers math software packages such as MathCad, TK-Solver, MATLAB, and spreadsheets so that readers can use the instruments with which they are the most familiar. He emphasizes the basic principles of conservation of mass, energy, and momentum, helping readers achieve true mastery of this important subject, rather than just learn routine techniques. With the enhanced understanding of the fundamental principles of fluid mechanics provided by this book, readers can then apply these principles to the solution of complex real-world problems. The book supplies the knowledge tools necessary to analyze and design economical and properly performing conveyance systems. Thus not only is the book useful for graduate students, but it also provides professional engineers the expertise and knowledge to design well performing and economical channel systems.

Download or read book Fields and Streams written by Rebecca Lave and published by University of Georgia Press. This book was released on 2012-11-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining the science of stream restoration, Rebecca Lave argues that the neoliberal emphasis on the privatization and commercialization of knowledge has fundamentally changed the way that science is funded, organized, and viewed in the United States. Stream restoration science and practice is in a startling state. The most widely respected expert in the field, Dave Rosgen, is a private consultant with relatively little formal scientific training. Since the mid-1990s, many academic and federal agency-based scientists have denounced Rosgen as a charlatan and a hack. Despite this, Rosgen's Natural Channel Design approach, classification system, and short-course series are not only accepted but are viewed as more legitimate than academically produced knowledge and training. Rosgen's methods are now promoted by federal agencies including the Environmental Protection Agency, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Natural Resources Conservation Service, as well as by resource agencies in dozens of states. Drawing on the work of Pierre Bourdieu, Lave demonstrates that the primary cause of Rosgen's success is neither the method nor the man but is instead the assignment of a new legitimacy to scientific claims developed outside the academy, concurrent with academic scientists' decreasing ability to defend their turf. What is at stake in the Rosgen wars, argues Lave, is not just the ecological health of our rivers and streams but the very future of environmental science.
Download or read book The Mekong Delta System written by Fabrice G. Renaud and published by Springer Science & Business Media. This book was released on 2012-06-01 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book about the Mekong Delta presents a unique collection of state-of-the-art contributions by international experts from different scientific disciplines about the characteristics and pressing water-related challenges of the Mekong Delta in Vietnam. The Mekong Delta belongs to one of the areas, which are to expect the largest challenges concerning environmental change and climate change induced sea level rise . The Delta acts as the “rice bowl” of Southeast Asia and is home to over 17 Million people, who need to cope with ecologic as well as socio-economic changes linked to the rapid economic development of the country. Annual floods, severe droughts, salt water intrusion, degrading water quality, tropical cyclones, hydrologic changes due to hydropower projects in the upstream of the Mekong, coastal erosion, and the loss of biodiversity are some of the problems in the region. Heterogeneous resource management responsibilities, and the fact that the Mekong – and thus also the Delta – is influenced by six countries aggravate the situation. Integrated water resources management and fostered cooperation and information exchange are pressing needs for the sustainable development of the Delta.

Download or read book California Rivers and Streams written by Jeffrey F. Mount and published by Univ of California Press. This book was released on 2023-09-01 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: California Rivers and Streams provides a clear and informative overview of the physical and biological processes that shape California's rivers and watersheds. Jeffrey Mount introduces relevant basic principles of hydrology and geomorphology and applies them to an understanding of the differences in character of the state's many rivers. He then builds on this foundation by evaluating the impact on waterways of different land use practices—logging, mining, agriculture, flood control, urbanization, and water supply development. Water may be one of California's most valuable resources, but it is far from being one we control. In spite of channels, levees, lines and dams, the state's rivers still frequently flood, with devastating results. Almost all the rivers in California are dammed or diverted; with the booming population, there will be pressure for more intervention. Mount argues that Californians know little about how their rivers work and, more importantly, how and why land-use practices impact rivers. The forceful reconfiguration and redistribution of the rivers has already brought the state to a critical crossroads. California Rivers and Streams forces us to reevaluate our use of the state's rivers and offers a foundation for participating in the heated debates about their future.
Download or read book The History of the Study of Landforms written by Richard J. Chorley and published by Geological Society of London. This book was released on 1964 with total page 1068 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the fourth volume in the definitive series, The History of the Study of Landforms or The Development of Geomorphology. Volume 1 (1964) dealt with contributions to the field up to 1890. Volume 2 (1973) dealt with the concepts and contributions of William Morris Davis. Volume 3 (1991) covered historical and regional themes during the 'classic' period of geomorphology, between 1980 and 1950. This volume concentrates on studies of geomorphological processes and Quaternary geomorphology, carrying on these themes into the second part of the twentieth century, since when process-based studies have become so dominant. It is divided into five sections. After chapters dealing with geological controls, there are three sections dealing with process and form: fluvial, glacial and other process domains. The final section covers the mid-century revolution, anticipating the onset of quantitative studies and dating techniques. The volume's objective is to describe and analyse many of the developments that provide a foundation for the rich and varied subject matter of contemporary geomorphology. The volume is in part a celebration of the late Professor Richard Chorley, who devised its structure and contributed a chapter.

Download or read book Archaeological Landscapes of the Near East written by T. J. Wilkinson and published by University of Arizona Press. This book was released on 2003-11-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society for American Archaeology Book Award Winner Many fundamental studies of the origins of states have built upon landscape data, but an overall study of the Near Eastern landscape itself has never been attempted. Spanning thousands of years of history, the ancient Near East presents a bewildering range of landscapes, the understanding of which can greatly enhance our ability to infer past political and social systems. Tony Wilkinson now shows that throughout the Holocene humans altered the Near Eastern environment so thoroughly that the land has become a human artifact, albeit one that retains the power to shape human societies. In this trailblazing book—the first to describe and explain the development of the Near Eastern landscape using archaeological data—Wilkinson identifies specific landscape signatures for various regions and periods, from the early stages of complex societies in the fifth to sixth millennium B.C. to the close of the Early Islamic period around the tenth century A.D. From Bronze Age city-states to colonized steppes, these signature landscapes of irrigation systems, tells, and other features changed through time along with changes in social, economic, political, and environmental conditions. By weaving together the record of the human landscape with evidence of settlement, the environment, and social and economic conditions, Wilkinson provides a holistic view of the ancient Near East that complements archaeological excavations, cuneiform texts, and other conventional sources. Through this overview, culled from thirty years' research, Wilkinson establishes a new framework for understanding the economic and physical infrastructure of the region. By describing the basic attributes of the ancient cultural landscape and placing their development within the context of a dynamic environment, he breaks new ground in landscape archaeology and offers a new context for understanding the ancient Near East.
