This book was released on 1996-07-31 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwest--economic, recreational, symbolic--is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runs--and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problem--starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including Salmon biology and geography--their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activities--grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issue--policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.

This book was released on 2012-09-26 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dam and levee remediation has become more prevalent since the start of the twenty-first century. Given the vastness and complexity of the infrastructures involved, keeping up with maintenance needs is very difficult. Major surges in repair are usually triggered by nature’s wake-up calls, such as hurricanes, floods, and earthquakes. The challenge has been to develop methods that ensure safe, effective, reliable, and robust solutions for current and future remediation issues. Specialty Construction Techniques for Dam and Levee Remediation presents the state of practice in North American dam and levee remediation as it relates to the use of specialty geotechnical construction techniques, such as anchors, grouting, cutoff (diaphragm) walls, and deep mixing. The book focuses on the actual construction processes, describing design and performance aspects of remediation where appropriate. Chapters deal with the application of drilling and grouting methods, methods to install mix-in-place (category 2) cutoff structures, excavated and backfilled trenches (category 1), composite cutoff walls, and stabilization using prestressed rock anchors. The book also provides a comprehensive guide to dam and levee instrumentation, covering planning, operating principles, data management, staffing, and automation. As an educational and salutary example of ineffective efforts, the final chapter presents a case history of a series of remediations performed on a single project, which ultimately proved unsuccessful. A wide range of methods has been developed in response to the challenges that arise in the dam and levee remediation arena and the need for a competitive edge. These new methods are designed and monitored using state-of-the-art techniques, giving rise to the emergence of new intensity and initiative in this field. This book captures this transformation by examining the theory and practice of contemporary remedial techniques, using recent U.S. case histories to provide knowledge and inspiration to readers, both in North America and around the world.
