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.
An updated treatment of management and geomorphology of large rivers around the world The newly revised Second Edition of Large Rivers: Geomorphology and Management delivers a thoroughly updated exploration of the form and function of major rivers. The book brings together a set of papers on the large rivers of the world, offering readers an insightful examination of a demanding subject. The new Second Edition of the book includes fully updated and revised chapters, as well as two entirely new chapters on the Ayeyarwady and the Arctic rivers. This fascinating volume describes the environmental requirements for creating and maintaining a major river system, case studies on over a dozen large rivers from different continents in a variety of physical environments, and the measurement and management of large rivers. Unmatched in scope, Large Rivers sheds light on a subject lacking in comprehensive study. Readers will benefit from the inclusion of: A thorough introduction to the geology of large river systems, hydrology and discharge, transcontinental moving and storage of sediment, and the greatest floods and largest rivers An exploration of the classification, architecture, and evolution of large-river deltas Discussions of sedimentology and stratigraphy of large river deposits, including their recognition in the ancient record and the distinction from incised valley fills An examination of the effects of tectonism, climate change, and sea-level change on the form and behavior of the modern Amazon river and its floodplain Measurement and management of large rivers The effect of climatic change on large rivers Perfect for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management, Large Rivers: Geomorphology and Management will also earn a place in the libraries of engineers and environmental consultants in the private and public sectors working on major rivers around the world.
The purpose of this design manual is to provide restoration practitioners with guidelines for implementing a subset of low-tech tools--namely beaver dam analogues (BDAs) and post-assisted log structures (PALS)--for initiating process-based restoration in structurally-starved riverscapes. While the concept of process-based restoration in riverscapes has been advocated for at least two decades, details and specific examples on how to implement it remain sparse. Here, we describe 'low-tech process-based restoration' as a practice of using simple, low unit-cost, structural additions (e.g. wood and beaver dams) to riverscapes to mimic functions and initiate specific processes. Hallmarks of this approach include: - An explicit focus on the processes that a low-tech restoration intervention is meant to promote.- A conscious effort to use cost-effective, low-tech treatments (e.g., hand-built, natural materials, non-engineered, short-term design life-spans) because of the need to efficiently scale-up application.- 'Letting the system do the work', which defers critical decision making to riverscapes and nature's ecosystem engineers.
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
This important book brings together eighteen cutting-edge researchpapers first presented at the Second International Conference onBraided Rivers. It includes the latest research on the dynamics,deposits and ecology of these rivers. Essential reading for geomorphologists, earth scientists,engineers and ecologists with a pure and applied interest in thestudy, modelling and management of braided rivers.
