Book Description
Chapter 4 of Duda, J.J., J.A. Warrick, and C.S. Magirl, eds., Coastal habitats of the Elwha River, Washington – Biological and physical patterns and processes prior to dam removal This report includes chapters that summarize the results of multidisciplinary studies to quantify and characterize the current (2011) status and baseline conditions of the lower Elwha River, its estuary, and the adjacent nearshore ecosystems prior to the historic removal of two long-standing dams that have strongly influenced river, estuary, and nearshore conditions. The studies were conducted as part of the U.S. Geological Survey Multi-disciplinary Coastal Habitats in Puget Sound (MD-CHIPS) project. Chapter 4 details a series of hydrological data collected by the MD-CHIPS Elwha project. These include groundwater monitoring, surface water-groundwater interactions in the estuary, an estimated surface-water budget to the estuary, and a series of temperature and salinity measurements.

Book Description
This Proceedings contains over 260 papers on cutting-edge research presented at the eighth international Symposium on Coastal Sediment Processes, held May 11 - 15, 2015, in San Diego, California, USA. This technical specialty conference was devoted to promoting an interdisciplinary exchange of state-of-the-art knowledge among researchers in the fields of coastal engineering, geology, oceanography, and related disciplines, with the theme of Understanding and Working with Nature.Focusing on the physical aspects of the sediment processes in various coastal environments, this Proceedings provides findings from the latest research and newest engineering applications. Sessions covered a wide range of topics including barrier islands, beaches, climate and sea level, cohesive and noncohesive sediments, coastal bluffs, coastal marsh, dredged sediments, inlet and navigation channels, regional sediment management, river deltas, shore protection, tsunamis, and vegetation-sediment interaction. Several special sessions included: Relevant science for changing coastlines: A Tribute to Gary Griggs; North Atlantic Coast Comprehensive Study and post-super-storm Sandy work; long-term coastal evolution; barrier islands of Louisiana; sea-level rise and super storms in a warming world; predicting decadal coastal geomorphic evolution; and contrasting Pacific coastal behavior with El Niño Southern Oscillation (ENSO), are also featured.

Chapter 2 of Duda, J.J., J.A. Warrick, and C.S. Magirl, eds., Coastal habitats of the Elwha River, Washington – Biological and physical patterns and processes prior to dam removal This report includes chapters that summarize the results of multidisciplinary studies to quantify and characterize the current (2011) status and baseline conditions of the lower Elwha River, its estuary, and the adjacent nearshore ecosystems prior to the historic removal of two long-standing dams that have strongly influenced river, estuary, and nearshore conditions. The studies were conducted as part of the U.S. Geological Survey Multi-disciplinary Coastal Habitats in Puget Sound (MD-CHIPS) project. In chapter 2, the volume and timing of sediment delivery to the estuary and nearshore are discussed, providing an overview of the sediment stored in the two reservoirs and the expected erosion mechanics of the reservoir sediment deposits after removal of the dams.

Book Description
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.

Book Description
CLICK HERE to download the first chapter from Elwha: A River Reborn (Provide us with a little information and we'll send your download directly to your inbox) A compelling exploration of one of the largest dam removal projects in the world—and the efforts to save a stunning Northwest ecosystem * Co-published with The Seattle Times * 125 color photographs, including rare historic images * Dam removal started in September 2011 while restoration work continues today In the fall of 2011, the Times was on hand when a Montana contractor removed the first pieces from two concrete dams on the Elwha River which cuts through the Olympic range. It was the beginning of the largest dam removal project ever undertaken in North America—one dam was 200 feet tall—and the start of an unprecedented attempt to restore an entire ecosystem. More than 70 miles of the Elwha and its tributaries course from the mountain headwaters to clamming beaches on the Strait of Juan de Fuca. Through interviews, field work, archival and historical research, and photojournalism, The Seattle Times has explored and reported on the dam removal, the Elwha ecosystem, its industrialization, and now its renewal. Elwha: A River Reborn is based on these feature articles. Richly illustrated with stunning photographs, as well as historic images, graphics, and a map, Elwha tells the interwoven stories of this region. Meet the Lower Elwha Klallam tribe, who anxiously await the return of renowned salmon runs savored over the generations in the stories of their elders. Discover the biologists and engineers who are bringing the dams down and laying the plan for renewal, including an unprecedented revegetation effort that will eventually cover more than 700 acres of mudflats. When the dam started to come down in Fall 2011—anticipated for more than 20 years since Congress passed the Elwha Restoration Act—it was the beginning of a $350 million project observed around the world. Elwha: A River Reborn is inspiring and instructive, a triumphant story of place, people, and environment striving to come together.

Book Description
Mass Transport, Gravity Flows, and Bottom Currents: Downslope and Alongslope Processes and Deposits focuses solely on important downslope and alongslope processes. The book provides clear definitions and characteristics based on soil mechanics, fluid mechanics and sediment concentration by volume. It addresses Slides, Slumps, and Debris Flows, Grain Flows, Liquefied/Fluidized Flows, and Turbidity Currents, Density plumes, Hyperpycnal Flows, the Triggering Mechanisms of Downslope Processes, Bottom Currents, and Soft-Sediment Deformation Structures. The mechanics of each process are described in detail and used to provide empirically-driven categories to help recognize these deposits it the rock record. Case studies clearly illustrate of the problems inherent in recognizing these processes in the rock record, and potential solutions are provided alongside future avenues of research. An appendix also provides step-by-step guidance in describing and interpreting sediments. - Comprehensively addresses modern downslope and alongslope processes, including definitions and mechanisms - Provides key criteria for the recognition of depositional facies in the rock record - Includes case studies to illustrate each downslope and alongslope process - Identifies key problems and potential solutions for future research - Uses pragmatic, empirical, data-driven interpretations to revise conventional facies models
