Download or read book Seasonal Snowpacks written by Trevor D. Davies and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonal Snowpacks examines the processes which control the chemistry of seasonal snowcover and provides detailed information on the biogeographical distribution of snow (e.g. urban, alpine snowpacks), snow composition (e.g. micropollutants, stable isotopes) or the physical and biological processes which influence the chemical changes in snow (e.g. wind, microbiological activity). The fluxes of chemicals at the snow-atmosphere and snow-soil interfaces are examined, as are processes which modify composition within the snowcover. It is the first book in which the reader will find a comprehensive overview of the theoretical concepts, latest measurement techniques, process-oriented research methods, and models of studies in snow chemistry. The linkages between snow chemistry, atmospheric chemistry and hydrology will make this book of use to both research workers and students in the physical and biological sciences and to natural resource management personnel.

Available in PDF, EPUB and Kindle. Book excerpt: The flow of water through layered snowpacks is discussed. A method for predicting flow through unsaturated layers is given. The flow along ice layers and through ice layers is analyzed in terms of the slope, permeability, thickness and length of the layers. It is shown that the permeability of ice layers required to cause large flow diversions is quite small. The effect of slope is large even at small angles. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.

This book was released on 2007-10-01 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.

Download or read book One dimensional Water Flow Through Snow written by Samuel C. Colbeck and published by . This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory is developed to describe the percolation of water through isothermal snow with a vertical porosity gradient. While the necessary laboratory experiments have not been done for snow, concepts from the general theory of two phase flow through porous media are used in the development. The general solution for the one-dimensional problem is given, which, when combined with any periodic boundary condition, can be used to make quantitative predictions. The theory is applied to water percolation through firn on the upper Seward Glacier. Using appropriate values for the parameters, theory shows a wave of volume flux which travels down into the firn and develops features similar to those observed by Sharp. These include an initially symmetric wave which distorts with depth, continuous (rather than intermittent) downward flow beneath the surface, and a decreasing value for the wave crest with depth. The theory predicts that the waves advance with a shock front which grows with depth. The shock front is thought to be only an approximation to the actual physical process. (Author).
Download or read book Sustaining Rocky Mountain Landscapes written by Tony Prato and published by Earthscan. This book was released on 2010-09-30 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prato and Fagre offer the first systematic, multi-disciplinary assessment of the challenges involved in managing the Crown of the Continent Ecosystem (CCE), an area of the Rocky Mountains that includes northwestern Montana, southwestern Alberta, and southeastern British Columbia. The spectacular landscapes, extensive recreational options, and broad employment opportunities of the CCE have made it one of the fastest growing regions in the United States and Canada, and have lead to a shift in its economic base from extractive resources to service-oriented recreation and tourism industries. In the process, however, the amenities and attributes that draw people to this 'New West' are under threat. Pastoral scenes are disappearing as agricultural lands and other open spaces are converted to residential uses, biodiversity is endangered by the fragmentation of fish and wildlife habitats, and many areas are experiencing a decline in air and water quality. Sustaining Rocky Mountain Landscapes provides a scientific basis for communities to develop policies for managing the growth and economic transformation of the CCE without sacrificing the quality of life and environment for which the land is renowned. The book begins with a natural and economic history of the CCE. It follows with an assessment of current physical and biological conditions in the CCE. The contributors then explore how social, economic, demographic, and environmental forces are transforming ecosystem structure and function. They consider ecosystem change in response to changing patterns of land use, pollution, and drought; the increasing risk of wildfire to wildlife and to human life and property; and the implications of global climate change on the CCE. A final, policy-focused section of the book looks at transboundary issues in ecosystem management and evaluates the potential of community-based and adaptive approaches in ecosystem management.

Download or read book Physical Characteristics of the Snow Cover Fort Greely Alaska 1966 67 written by Michael A. Bilello and published by . This book was released on 1970 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations were made at 19 sites in and around the Fort Greely Military Reservation in Alaska during the winter of 1966-67 to obtain data on the depth and physical properties of the snow cover. Snowfall in 1966-67 totaled 245 cm, which was more than 2-1/2 times the seasonal normal. Maximum snow depths of 80 to 100 cm were observed in a major portion of the reservation. Measurements at nine sites showed that the snow density at Fort Greely was generally light; e.g., the average density in the forest did not exceed 0.24 g/cu cm. However, exceptions such as at Jarvis Creek, where the density averaged 0.33 g/cu cm, could be expected. On the average, less snow falls at Fort Greely than at other interior Alaskan locations; but the average density of the snow cover at all interior Alaska sites is quite light. Relationships between snow-cover properties and climate were tested using data collected at Fort Greely. The results substantiated the relationships between (1) snow hardness and snow density measurements and (2) average snow densities with average windspeed and air temperatures. Snow temperature measurements at Fort Greely showed that the snow in the forest was colder than at exposed sites, primarily because the average air temperature within the forest canopy was lower than that in the open area.
