Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 194. Stream Restoration in Dynamic Fluvial Systems: Scientific Approaches, Analyses, and Tools brings together leading contributors in stream restoration science to provide comprehensive consideration of process-based approaches, tools, and applications of techniques useful for the implementation of sustainable restoration strategies. Stream restoration is a catchall term for modifications to streams and adjacent riparian zones undertaken to improve geomorphic and/or ecologic function, structure, and integrity of river corridors, and it has become a multibillion dollar industry. A vigorous debate currently exists in research and professional communities regarding the approaches, applications, and tools most effective in designing, implementing, and assessing stream restoration strategies given a multitude of goals, objectives, stakeholders, and boundary conditions. More importantly, stream restoration as a research-oriented academic discipline is, at present, lagging stream restoration as a rapidly evolving, practitioner-centric endeavor. The volume addresses these main areas: concepts in stream restoration, river mechanics and the use of hydraulic structures, modeling in restoration design, ecology, ecologic indices, and habitat, geomorphic approaches to stream and watershed management, and sediment considerations in stream restoration. Stream Restoration in Dynamic Fluvial Systems will appeal to scholars, professionals, and government agency and institute researchers involved in examining river flow processes, river channel changes and improvements, watershed processes, and landscape systematics.

Fluvial Geomorphology studies the biophysical processes acting in rivers, and the sediment patterns and landforms resulting from them. It is a discipline of synthesis, with roots in geology, geography, and river engineering, and with strong interactions with allied fields such as ecology, engineering and landscape architecture. This book comprehensively reviews tools used in fluvial geomorphology, at a level suitable to guide the selection of research methods for a given question. Presenting an integrated approach to the interdisciplinary nature of the subject, it provides guidance for researchers and professionals on the tools available to answer questions on river restoration and management. Thoroughly updated since the first edition in 2003 by experts in their subfields, the book presents state-of-the-art tools that have revolutionized fluvial geomorphology in recent decades, such as physical and numerical modelling, remote sensing and GIS, new field techniques, advances in dating, tracking and sourcing, statistical approaches as well as more traditional methods such as the systems framework, stratigraphic analysis, form and flow characterisation and historical analysis. This book: Covers five main types of geomorphological questions and their associated tools: historical framework; spatial framework; chemical, physical and biological methods; analysis of processes and forms; and future understanding framework. Provides guidance on advantages and limitations of different tools for different applications, data sources, equipment and supplies needed, and case studies illustrating their application in an integrated perspective. It is an essential resource for researchers and professional geomorphologists, hydrologists, geologists, engineers, planners, and ecologists concerned with river management, conservation and restoration. It is a useful supplementary textbook for upper level undergraduate and graduate courses in Geography, Geology, Environmental Science, Civil and Environmental Engineering, and interdisciplinary courses in river management and restoration.

This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.

All magnetized planets in our solar system (Mercury, Earth,Jupiter, Saturn, Uranus, and Neptune) interact strongly with thesolar wind and possess well developed magnetotails. It is not onlythe strongly magnetized planets that have magnetotails. Mars andVenus have no global intrinsic magnetic field, yet they possessinduced magnetotails. Comets have magnetotails that are formed bythe draping of the interplanetary magnetic field. In the case ofplanetary satellites (moons), the magnetotail refers to thewake region behind the satellite in the flow of either the solarwind or the magnetosphere of its parent planet. The largestmagnetotail of all in our solar system is the heliotail, the “magnetotail” of the heliosphere. The variety of solar wind conditions,planetary rotation rates, ionospheric conductivity, and physicaldimensions provide an outstanding opportunity to extend ourunderstanding of the influence of these factors on magnetotailprocesses and structures. Volume highlights include: Discussion on why a magnetotail is a fundamental problemof magnetospheric physics Unique collection of tutorials on a large range of magnetotailsin our solar system In-depth reviews comparing magnetotail processes at Earth withother magnetotail structures found throughout the heliosphere Collectively, Magnetotails in the Solar System bringstogether for the first time in one book a collection of tutorialsand current developments addressing different types ofmagnetotails. As a result, this book should appeal to a broadcommunity of space scientists, and it should also be of interest toastronomers who are looking at tail-like structures beyond oursolar system.

The Galápagos Islands are renown for their unique flora and fauna, inspiring Charles Darwin in the elaboration of his theory of evolution. Yet in his Voyage of the Beagle, published in 1839, Darwin also remarked on the fascinating geology and volcanic origin of these enchanted Islands. Since then, the Galápagos continue to provide scientists with inspiration and invaluable information about ocean island formation and evolution, mantle plumes, and the deep Earth. Motivated by an interdisciplinary Chapman Conference held in the Islands, this AGU volume provides cross-disciplinary collection of recent research into the origin and nature of ocean islands, from their deepest roots in Earth's mantle, to volcanism, surface processes, and the interface between geology and biodiversity. Volume highlights include: Case studies in biogeographical, hydrological, and chronological perspective Understanding the connection between geological processes and biodiversity Synthesis of decades of interdisciplinary research in physical processes from surface to deep interior of the earth In-depth discussion of the concept of the island acting as a natural laboratory for earth scientists Integrated understanding of the Galápagos region from a geological perspective Collectively, The Galápagos presents case studies illustrating the Galápagos Archipelago as a dynamic natural laboratory for the earth sciences. This book would be of special interest to a multidisciplinary audience in earth sciences, including petrologists, volcanologists, geochronologists, geochemists, and geobiologists.

German description: Benötigen wir fuer eine erfolgreiche Erforschung geomorphologischer Prozesse und Formen ueberhaupt Theorie? Sind potentiell gefährliche Prozesse wie Hangrutschungen nicht ganz offensichtlich vorhanden? Diese Fragen nach den theoretischen Grundannahmen der eigenen Disziplin beruehren das Selbstverständnis der Geomorphologie, deren Vertretern oftmals eine ausgeprägte Theorie-Abneigung nachgesagt wird. Wie aber steht es um eine Wissenschaft, in der theoretische Arbeiten die Ausnahme sind? Kann die Geomorphologie nicht letztlich sogar von einer verstärkten Auseinandersetzung mit ihren theoretischen Grundlagen profitieren? Der theoretische Rahmen fuer geomorphologische Arbeiten wird nicht nur erweitert, sondern neu abgesteckt und vor allem auch interdisziplinär anschlussfähig gemacht. Mehrfach ausgezeichnet mit: Dissertationspreis des Jahres 2010 des Deutschen Arbeitskreises fuer Geomorphologie der DGfG, Hans Bobek-Preis der Ã_sterreichischen Geographischen Gesellschaft (Ã_GG) 2010 und Springer Theses Prize im Jahr 2011.
