Download or read book Historical Alterations to the Columbia River Gorge as a Result of Transportation Infrastructure 1850 1900 written by Isaac B. Daniel and published by . This book was released on 2005 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring high waterfalls and forested cliffs, and displaying a remarkable transition between the Pacific and Interior west, the Columbia River Gorge reveals the grandeur of western landscapes. Yet the landscape that one sees today is an amalgamation of the Gorge's natural setting and its unique human history. Historical research on the Gorge is deficient, as few studies have addressed landscape change that occurred prior to the twentieth century. This research explores a significant yet underrepresented chapter in the Gorge's history, focusing on the second half of the nineteenth century. Specifically, this research examines changes in the land that resulted from building transportation infrastructure during this era, namely the development of portage, wagon, and military roads and in-stream navigational aids. Utilizing methods drawn from historical geography, this research employs a wide range of primary source materials, including journals, photographs, surveys, and construction records, to assess landscape change. Results from this study indicate a high spatial extent of landscape impacts resulting from transportation infrastructure put in place between 1850 and 1900. The clearing of floodplain forests, coupled with changes in the hydrography of the river channel brought about by the construction of the Cascade canal and lock, led to significant changes in ecological functions, including nutrient cycling and sediment retention. These results provide suggestions for restoration efforts in the Gorge and also hold important applications for historical interpretation in the contemporary National Scenic Area. There are also broad implications for researchers seeking a broader understanding of changes in western riparian landscapes during this period.

Download or read book Colorado River Basin Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-06-30 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

Download or read book Climate Impacts on Energy Systems written by Jane O. Ebinger and published by World Bank Publications. This book was released on 2011 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: "While the energy sector is a primary target of efforts to arrest and reverse the growth of greenhouse gas emissions and lower the carbon footprint of development, it is also expected to be increasingly affected by unavoidable climate consequences from the damage already induced in the biosphere. Energy services and resources, as well as seasonal demand, will be increasingly affected by changing trends, increasing variability, greater extremes and large inter-annual variations in climate parameters in some regions. All evidence suggests that adaptation is not an optional add-on but an essential reckoning on par with other business risks. Existing energy infrastructure, new infrastructure and future planning need to consider emerging climate conditions and impacts on design, construction, operation, and maintenance. Integrated risk-based planning processes will be critical to address the climate change impacts and harmonize actions within and across sectors. Also, awareness, knowledge, and capacity impede mainstreaming of climate adaptation into the energy sector. However, the formal knowledge base is still nascent?information needs are complex and to a certain extent regionally and sector specific. This report provides an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty. It focuses on energy sector adaptation, rather than mitigation which is not discussed in this report. This report draws largely on available scientific and peer-reviewed literature in the public domain and takes the perspective of the developing world to the extent possible."

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book excerpt: The Hill and Wang Critical Issues Series: concise, affordable works on pivotal topics in American history, society, and politics. In this pioneering study, White explores the relationship between the natural history of the Columbia River and the human history of the Pacific Northwest for both whites and Native Americans. He concentrates on what brings humans and the river together: not only the physical space of the region but also, and primarily, energy and work. For working with the river has been central to Pacific Northwesterners' competing ways of life. It is in this way that White comes to view the Columbia River as an organic machine--with conflicting human and natural claims--and to show that whatever separation exists between humans and nature exists to be crossed.
