This book was released on 2018-03-29 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1980 eruption of Mount St. Helens in southwest Washington State radically changed the physical and socio-economic landscapes of the region. The eruption destroyed the summit of the volcano, sending large amounts of debris into the North Fork Toutle River, and blocking the sole means of drainage from Spirit Lake 4 miles north of Mount St. Helens. As a result of the blockage, rising lake levels could cause failure of the debris blockage, putting the downstream population of approximately 50,000 at risk of catastrophic flooding and mud flows. Further, continued transport of sediment to the river from volcanic debris deposits surrounding the mountain reduces the flood carrying capacity of downstream river channels and leaves the population vulnerable to chronic flooding. The legacy of the 1980 eruption and the prospect of future volcanic, seismic, and flood events mean that risk management in the Spirit Lake Toutle River system will be challenging for decades to come. This report offers a decision framework to support the long-term management of risks related to the Spirit Lake and Toutle River system in light of the different regional economic, cultural, and social priorities, and the respective roles of federal, tribal, state, and local authorities, as well as other entities and groups in the region. It also considers the history and adequacy of characterization, monitoring, and management associated with the Spirit Lake debris blockage and outflow tunnel, other efforts to control transport of water and sediment from the 1980 and later eruptions, and suggests additional information needed to support implementation of the recommended decision framework.

Download or read book Analysis and Modelling of River Meandering written by Alessandra Crosato and published by IOS Press. This book was released on 2008 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the morphological changes of non-tidal meandering rivers at the spatial scale of several meanders. With this purpose, a physics-based mathematical model, MIANDRAS, has been developed for the simulation of the medium-term to long-term evolution of meandering rivers. Application to several real rivers shows that MIANDRAS can properly simulate both equilibrium river bed topography and planimetric changes. Three models of different complexity can be obtained by applying different degrees of simplification to the equations. These models, along with experimental tests and field data, constitute the tools for several analyses. At conditions of initiation of meandering, it is found that river bends can migrate upstream and downstream. This depends on meander wave length and width-to-depth ratio, irrespective of whether the parameters are in the subresonant or the superresonant range.
Download or read book Anticipated sediment delivery to the lower Elwha River during and following dam removal written by Christiana R. Czuba and published by U.S. Department of the Interior, U.S. Geological Survey. This book was released on 2011-09-07 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Benthic Foraminifera of the Gulf of Mexico written by C. Wylie Poag and published by Texas A&M University Press. This book was released on 2015-03-15 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1981, Woods Hole researcher C. Wylie Poag published the book Ecological Atlas of the Benthic Foraminifera of the Gulf of Mexico. In this new volume, Poag has revised and updated the atlas, incorporating three decades of extensive data collections from the open Gulf and from an additional seventeen estuarine systems to cover species of benthic foraminifera from more than eight thousand sample stations. Benthic Foraminifera of the Gulf of Mexico features 68 plates of scanning electron photomicrographs, 64 color figures, and a large color foldout map, indicating species distribution of forams. This book is designed to aid students and teachers of geology, biology, oceanography, and ecology, as well as micropaleontologists in government and industry laboratories, and other researchers and consultants who have an interest in benthic ecology or paleoecology.
Download or read book Soil and Water Conservation Advances in the United States written by Teddy Michael Zobeck and published by ASA-CSSA-SSSA. This book was released on 2010 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.
Download or read book Tools in Fluvial Geomorphology written by G. Mathias Kondolf and published by John Wiley & Sons. This book was released on 2016-04-28 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
