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 Riparian Landscapes written by George Patrick Malanson and published by Cambridge University Press. This book was released on 1993-05-27 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.

Download or read book Submarine Landslides written by Kei Ogata and published by John Wiley & Sons. This book was released on 2019-12-24 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination of ancient and contemporary submarine landslides and their impact Landslides are common in every subaqueous geodynamic context, from passive and active continental margins to oceanic and continental intraplate settings. They pose significant threats to both offshore and coastal areas due to their frequency, dimensions, and terminal velocity, capacity to travel great distances, and ability to generate potentially destructive tsunamis. Submarine Landslides: Subaqueous Mass Transport Deposits from Outcrops to Seismic Profiles examines the mechanisms, characteristics, and impacts of submarine landslides. Volume highlights include: Use of different methodological approaches, from geophysics to field-based geology Data on submarine landslide deposits at various scales Worldwide collection of case studies from on- and off-shore Potential risks to human society and infrastructure Impacts on the hydrosphere, atmosphere, and lithosphere

Download or read book Silt Turbidity and Suspended Sediments in the Aquatic Environment written by Ontario. Ministry of Natural Resources. Southern Region. Science and Technology Transfer Unit and published by Brockville : Ontario Ministry of Natural Resources, Science and Technology Transfer Unit. This book was released on 1995 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impacts of siltation and suspended sediments on water quality and resident aquatic organisms is one of the most common problems facing resource managers today. Most construction activities in or near a watercourse have the potential to result in decreased shoreline stability and/or an increase in siltation, suspended sediments and turbidity. This annotated biliography was prepared in response to requests from seveal Ontario Ministry of Natural Resources biologists and technicians in the Southern Region. The author attempted to assemble and summarize reference material on various aspects of this topic including sources of suspended solids, physical/chemical processes, impacts to water quality and aquatic life, and remediations. This bibliography is intended to prove a consolidation and synthesis of information which is readily available for day-to-day use by field staff. Almost 1200 references are cited.
