The Role of Eolian Sediment in the Preservation of Archeologic Sites Along the Colorado River Corridor in Grand Canyon National Park, Arizona
ISBN: 9781496083081 / Angielski / Miękka / 78 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This report summarizes a 3-year study of eolian sedimentary processes in the Colorado River corridor, Grand Canyon National Park, Ariz., and discusses the relevance of those processes to the preservation of archeologic sites. The results reported here are based on detailed sedimentologic and geomorphologic investigations in three reaches of the river corridor, as well as continuous measurements of wind, rainfall, and sand transport at six sites for as long as 26 months, short-term field study at 35 other sites, examination of historical aerial photographs, and review of data collected and...

Deglaciation and Postglacial Treeline Fluctuation in the Northern San Juan Mountains, Colorado
ISBN: 9781496083593 / Angielski / Miękka / 56 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The San Juan Mountains of southwestern Colorado contain numerous lakes and bogs at and above treeline. In June 1978, Lake Emma, a tarn above present-day treeline, was suddenly drained by the collapse of underground mine workings. This study was initiated because the draining exposed a well-preserved archive of subfossil coniferous wood fragments that provided a unique opportunity to further our understanding of the paleoclimatic history of this region.

Geomorphic Response of the Sandy River, Oregon, to Removal of Marmot Dam
ISBN: 9781496099259 / Angielski / Miękka / 74 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The October 2007 breaching of a temporary cofferdam constructed during removal of the 15-meter (m)-tall Marmot Dam on the Sandy River, Oregon, triggered a rapid sequence of fluvial responses as 730,000 cubic meters of sand and gravel filling the former reservoir became available to a high-gradient river. Using direct measurements of sediment transport, photogrammetry, airborne light detection and ranging (lidar) surveys, and, between transport events, repeat ground surveys of the reservoir reach and channel downstream, we monitored the erosion, transport, and deposition of this sediment in...

Capacitively Coupled Resistivity Survey of Selected Irrigation Canals Within the North Platte River Valley, Western Nebraska and Eastern Wyoming, 2004
ISBN: 9781496110749 / Angielski / Miękka / 78 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Water resources of portions of the North Platte River basin are designated as being over-appropriated by the State of Nebraska Department of Natural Resources (DNR). An over-appropriated basin designation means that the existing demand on the surface and hydrologically connected groundwater resources are greater than the supply, resulting in decreased surface-water flows and water-table levels. To comply with State law, the North Platte Natural Resources District (NPNRD), in cooperation with the DNR, is developing an Integrated Management Plan (IMP) for groundwater and surface water in the...

Trends in Streamflow Characteristics of Selected Sites in the Elkhorn River, Salt Creek, and Lower Platte River Basins, Eastern Nebraska, 1928?2004, a
ISBN: 9781496120274 / Angielski / Miękka / 98 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Nebraska Department of Natural Resources approved instream-flow appropriations on the Platte River to maintain fish communities, whooping crane roost habitat, and wet meadows used by several wild bird species. In the lower Platte River region, the Nebraska Game and Parks Commission owns an appropriation filed to maintain streamflow for fish communities between the Platte River confluence with the Elkhorn River and the mouth of the Platte River. Because Elkhorn River flow is an integral part of the flow in the reach addressed by this appropriation, the Upper Elkhorn and Lower Elkhorn...

Occurrence of Pesticides in Ground Water of Wyoming, 1995?2006
ISBN: 9781496120373 / Angielski / Miękka / 82 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Little existing information was available describing pesticide occurrence in ground water of Wyoming, so the U.S. Geological Survey, in cooperation with the Wyoming Department of Agriculture and the Wyoming Department of Environmental Quality on behalf of the Wyoming Ground-water and Pesticides Strategy Committee, collected ground-water samples twice (during late summer/early fall and spring) from 296 wells during 1995-2006 to characterize pesticide occurrence. Sampling focused on the State's ground water that was mapped as the most vulnerable to pesticide contamination because of either...

ISBN: 9781496121035 / Angielski / Miękka / 66 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Topographic change of archeological sites within the Colorado River corridor of Grand Canyon National Park (GCNP) is a subject of interest to National Park Service (NPS) managers and other stakeholders in the Glen Canyon Dam Adaptive Management Program. Although long-term topographic change resulting from a variety of natural processes is typical in the Grand Canyon region, a continuing debate exists on whether and how controlled releases from Glen Canyon Dam, located immediately upstream of GCNP, are affecting rates of site erosion, artifact transport, and the preservation of archeological...
