Book Water Quality and Streamflow in the Caribou Poker Creeks Research Watershed Central Alaska 1979 Classic Reprint

Download or read book Water Quality and Streamflow in the Caribou Poker Creeks Research Watershed Central Alaska 1979 Classic Reprint written by Jerry W. Hilgert and published by Forgotten Books. This book was released on 2018-01-09 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Water Quality and Streamflow in the Caribou-Poker Creeks Research Watershed, Central Alaska, 1979 Baseline data from 1979 are presented on precipitation, streamflow, occurrence of permafrost, and physical and chemical water quality in a subarctic, tiaga watershed. First to third-order streams drain catchments embracing permafrost-underlain and permafrost-free landscapes in the undisturbed research watershed. The data are compared to those from a fourth-order stream impacted by placer mining; streams in the research watershed drain into the fourth-order stream slightly beyond the watershed border. These and subsequent baseline data sets will be used to compare natural conditions in undisturbed streams of the subarctic to conditions in streams impacted by resource management activities and to evaluate the impacts of such activities on stream ecosystems. Keyword: Baseline data, water quality, streamflow, subarctic environment, Alaska (caribou-poker Creeks research watershed).

Book Soils of the Caribou Poker Creeks Research Watershed Interior Alaska

Download or read book Soils of the Caribou Poker Creeks Research Watershed Interior Alaska written by and published by . This book was released on 1972 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils of the 41.5 sq miles Caribou-Poker Creeks Research Watershed, central Alaska, have been mapped by standard Soil Conservation Service (USDA) methods. Seven soil series are recognized: Bradway silt loams, Ester silt loams, Karshner silt loams and Saulich silt loams, all underlain by permafrost at shallow depth, make up 27% of the basin area. Olnes silt loams, Gilmore silt loams and Fairplay silt loams, covering 73% of the watershed area, are free from permafrost. Areal distribution of soils is depicted on a photo-mosaic base at 1:31, 680 scale. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 4th Symposium on River, Coastal and Estuarine Morphodynamics offers the latest research results concerning quantitative modelling of the interaction of water and sediment and the shapes this interaction makes in rivers, watersheds, estuaries, the coast, the continental shelf and the deep sea. Morphodynamics is the study of the evolution of landscape and seascape features, from small scale to large.

Book Tunnelling A Decade of Progress GeoDelft 1995 2005

Download or read book Tunnelling A Decade of Progress GeoDelft 1995 2005 written by Adam Bezuijen and published by CRC Press. This book was released on 2005-12-22 with total page 1306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following years of research, the first bored tunnel in soft soil in the Netherlands, the Tweede Heinenoord tunnel, was completed in 1998. Since then, Dutch engineers have increased their knowledge of soft soil tunnelling, with a significant and important part of this research being carried out by GeoDelft, the Dutch National Institute of Geo-Engineering. This book contains the most important publications by GeoDelft on the subject of soft soil tunnelling, focusing on the period from 1992 to the present, it is divided into four main headings: field measurements; grout behaviour; model testing; and numerical analysis. This impressive overview of the progress made in the Netherlands in soft soil tunnelling research over more than a decade is a valuable resource to those working in soft soil tunnelling worldwide.

Book Boreal Forests and Global Change

Download or read book Boreal Forests and Global Change written by Michael J. Apps and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boreal forests form Earth's largest terrestrial biome. They are rich in ecosystem and landscape diversity, though characterized by relatively few plant species, as compared to other forested regions. The long term viability and sustainability of boreal forests is influenced by many factors. They are subject to interruptions at intervals by large-scale natural disturbances, and increasingly by human activities. Boreal ecosystem development is typically a slow process; hence rapid changes in the global environment may invoke complex responses. Many industrial nations border, or lie within, boreal regions, deriving much of their economic wealth and culture from the forests. The response of boreal forests to changes in the global environment - whether caused by direct human activity or by indirect changes such as the anticipated changes in climate - are therefore of considerable international interest, both for their policy implications and their scientific challenges. This book which contains almost 50 peer-reviewed papers from a world-wide group of experts assembled under the auspices of IBFRA, the International Boreal Forest Research Association, covers topics which will stimulate further research and the development of constructive policies for improved management and conservation of global boreal forest resources.

Book Watershed Management

Download or read book Watershed Management written by Robert J. Naiman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).
