Book Thermokarst Evolution and Sediment Transport Study in the Caribou Poker Creeks Research Watershed Alaska

Download or read book Thermokarst Evolution and Sediment Transport Study in the Caribou Poker Creeks Research Watershed Alaska written by Prathap Kodial and published by . This book was released on 2005 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The role of sediment transport processes in the development and evolution of cryogenic features like thermo karsts have been overlooked by researchers. The current study is an attempt to better understand sediment transport and associated processes underlying the rapid growth of a thermokarst located in the Caribou-Poker Creeks Research Watershed. Within a short span of two warm summers, the study area has progressed from a hummocky terrain to a well incised channel configuration. Suspended sediment concentration and discharge analyses indicate high sediment flow following precipitation events, which play a major part in the sediment transport process. Mass sediment flows due to cryogenic piping were a result of interflow within the active layer. Fluvio-thermal erosion triggered block failures in the thermokarst. Topographical surveys spanning the two field seasons quantify the upstream erosion rate of more than 3.5 meters per year. Accelerated growth of the thermokarst has made the adjacent areas highly susceptible to secondary geomorphologic features"--Leaf iii.

Book Encyclopedia of Snow Ice and Glaciers

Download or read book Encyclopedia of Snow Ice and Glaciers written by Vijay P. Singh and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 1301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

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).

Book Caribou Poker Creeks Research Watershed Interior Alaska Background and Current Status

Download or read book Caribou Poker Creeks Research Watershed Interior Alaska Background and Current Status written by Charles W. Slaughter and published by . This book was released on 1971 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caribou-Poker Creeks Research Watershed was established in 1969 as a site for cooperative, inter-agency investigation of hydrologic and related aspects of a subarctic environemnt. The relatively undisturbed 4O-square-mile drainage basin includes both permafrost-dominated and non-permafrost watersheds, and has a variety of vegetation communities. Initial research is directed to furthering understanding of hydrologic behavior of north-facing (permafrost) and south-facing (non-permafrost) basins in this upland setting. (Author).

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).
