This book was released on 2024-09-20 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are vital ecosystems that support aquatic and terrestrial biodiversity and several ecosystem services, including food, water, culture, and recreation. After centuries of building dams on rivers across the world, dam removal projects are now on the rise due to obsolescence, reservoir sedimentation, insufficient return on investment, or river restoration and conservation priorities. Most dam removal projects have focused on smaller structures (< 10 m in structural height), but larger structures have also started to be removed in increasing numbers as practitioners, river managers, conservationists, and the public have gained more experience with the practice. Recent estimates suggest that only a small fraction of dam removals have been scientifically studied, and include mostly small dams and short time scales. Documenting the long-term ecological outcomes of large dam removal (i.e. >10 m tall) represents a new frontier in dam removal research: projects are more recent and provide an opportunity to understand the complex ecological changes that occur with these transformative restoration projects. Here, we aim to collate a diverse array of papers on long-term dam removal research projects involving larger dams (>10 m) to synthesize the issues, outcomes, tools, and experimental designs used to study large dam removal projects from physical, biological, and ecological perspectives. With this collection, we aim to showcase diverse global projects on ecosystem responses to large dam removal; collect perspectives from different disciplines, fields, and geographies; and synthesize the current state of knowledge in this area. We expect that this Research Topic will be informative to ongoing, long-term ecological restoration and monitoring projects related to dam removal as well as to upcoming large dam removal projects. We welcome contributions from all disciplines addressing the physical, ecological, and ecosystem responses to large-scale dam removal. Contributions could include original research in a specific discipline or area, case studies, or synthesis papers that address one or more of these topics in a transdisciplinary approach. Contributors could address any of the following major topics as related to outcomes of large dam removal, alone or in combination: Freshwater, estuarine, and marine aquatic biota; River and reservoir geomorphology; Terrestrial and riparian vegetation; Wildlife; Sedimentation; and Modelling. We would like contributors to highlight key results in their area of study, cross-disciplinary insights, and lessons learned that could inform ongoing monitoring and research efforts in current projects as well as upcoming large dam removals.
Download or read book Ecological Restoration in the Midwest written by Christian Lenhart and published by University of Iowa Press. This book was released on 2018-06-01 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people do not realize it, but the Midwest has been at the forefront of ecological restoration longer than perhaps any other region in the United States, dating back to the 1930s. Because of its industrial history, agricultural productivity, and natural features such as the Great Lakes, the Midwest has always faced a unique set of ecological challenges. Focusing on six cutting-edge case studies that highlight thirty restoration efforts and research sites throughout the region— Iowa, Indiana, Illinois, Wisconsin, Michigan, Minnesota, and Ohio— editors Christian Lenhart and Peter “Rocky” Smiley Jr. bring together a group of scholars and practitioners to show how midwestern restoration efforts have developed, as well as where they are headed. Whether cleaning up contamination from auto plants in Ohio, or restoring native prairie grasses along the Iowa highway, the contributors uncover a vast network of interested citizens and volunteer groups committed to preserving the region’s environment. This study, intended for researchers, students, and practitioners, also provides an updated synthesis of restoration theory and practice, and pinpoints emerging issues of importance in the Midwest, such as climate change and the increase in invasive species it will bring to the region. Though focusing exclusively on the Midwest, the contributors demonstrate how these case studies apply to restoration efforts across the globe. Contributors: Luther Aadland, David P. Benson, Andrew F.

Download or read book River Channel Management written by Peter Downs and published by Routledge. This book was released on 2014-02-24 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: River Channel Management is the first book to deal comprehensively with recent revolutions in river channel management. It explores the multi-disciplinary nature of river channel management in relation to modern management techniques that bear the background of the entire drainage basin in mind, use channel restoration where appropriate, and are designed to be sustainable. River Channel Management is divided into five sections: ·The Introduction outlines the need for river channel management . ·Retrospective Review offers an overview of twentieth century engineering methods and the ways that river channel systems operate. ·Realisation explains how greater understanding of river channel adjustments, channel hazards and river basin planning created a context for twenty-first century management. ·Requirements for Management explains and examines environmental assessment, restoration-based approaches, and methods that work towards 'design with nature' ·Final Revision speculates about prospects for twenty-first century river channel management. River Channel Management is written for higher-level undergraduates and for postgraduates in geography, ecology, engineering, planning, geology and environmental science, for professionals involved in river channel management, and for staff in environmental agencies.
Download or read book Dams and Geomorphology written by P.J. Beyer and published by Elsevier. This book was released on 2005-12-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dams profoundly impact the geomorphology of rivers by altering the natural patterns of water, sediment and energy flow in rivers. These changes have a largely negative impact on aquatic and riparian ecosystems upstream and downstream of the dam. Natural dams also impact river geomorphology, although with positive and negative repercussions for aquatic and riparian organisms. In 2002, the 33rd Binghamton Geomorphology Symposium convened under the theme "Dams and Morphology," and featured invited papers and contributed posters on topics of natural dams, artificial dams, and dam removal. Fourteen of these papers have been included in this volume.

Download or read book Vegetation Colonization Within Exposed Reservoirs Following Dam Removal on the Elwha River Washington written by Jarrett L. Schuster and published by . This book was released on 2015 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Riparian ecosystems are important for ecological functioning of rivers, and are significantly impacted by dams. With over 50% of large dams in the U.S. beyond their life expectancy, dam removal is increasingly being considered to eliminate aging infrastructure and restore ecosystems. There have been few large dam removals to date, so studies assessing vegetation succession on exposed reservoir sediments are limited. My research aims to assess how environmental factors within exposed reservoirs affect vegetation succession following removal of two dams on the Elwha River, Washington. In addition, I compared patterns of vegetation among the two reservoirs and their landforms. To do this, I sampled 67 100m2 plots in 2013 and 60 100m2 plots in 2014 along 10 transects within Mills and Aldwell Reservoirs. In each plot , I recorded vascular plant species composition and woody species height. I collected and pooled 8 soil samples (20 cm) / plot to assess percent organic matter, nutrients, and percent sand, silt, clay, and conducted a Wolman Pebble Count. I used a structural equation models to show how environmental factors related to hydrology, soil nutrients, and dispersal distance affect species diversity and cover. I compared environmental factors and vegetation responses among the two reservoirs using general linear models. Structural equation models showed that soil nutrient levels, sediment texture, ground cover, and landform were the environmental factors most related to reservoir revegetation patterns. Native species richness and cover, and exotic species cover were highest on valley walls and were positively related to high percent organic matter and % silt, but negatively related to % litter, D50, Mg, and P. In contrast, exotic richness was highest on terrace and riparian landforms with low % litter, Mg, and P and high % organic matter that were furthest away from established forest communities. Sediment nutrient indicator variables organic matter, Mg, and P were co-correlated with other sediment variables and act only as a surrogate for those variables in these models. In total, 147 vascular plant species were sampled in the two reservoirs of which 47 (31%) were exotic. Aldwell reservoir contained higher native and exotic species richness, cover, and woody species growth, and had finer textured sediments, deeper sediment depth to refusal, and higher % litter ground cover than Mills reservoir in 2013, while Mills reservoir had higher % gravel ground cover. By 2014, the only significant difference between reservoirs was woody species height, which was higher in Aldwell reservoir. Native species richness and cover were higher than that of exotic species in both reservoirs; however, exotic species are increasing, particularly along riparian zones within both reservoirs and on the most fertile sites along Aldwell valley walls and terraces. The increase in exotic species occurred despite active management to control them, and should be a concern to Olympic National Park because the reservoirs could become a gateway of exotic species invasion into a relatively protected landscape. Over time, I expect multiple vegetation communities to form within each reservoir associated with landform. Valley walls will likely return to the composition and structure of surrounding upland forests, while riparian zones will likely come to resemble the upstream Elwha River reaches not affected by damming. Terraces, on the other hand, will likely form novel vegetation communities dependent on environmental factors that will differ between the two reservoirs. The results of my study highlight the effect of varying environmental conditions on vegetation recovery rates and can help inform the Elwha River restoration project as well as any future dam removal projects"--Leaves iv-v.
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.

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.
