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.

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 Ni¤o Southern Oscillation (ENSO), are also featured.

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.
