Simulated Water-Management Alternatives Using the Modular Modeling System for the Methow River Basin, Washington
Christopher P. Konrad
2004, Open-File Report 2004-1051
A precipitation-runoff model for the Methow River Basin was used to simulate six alternatives: (1) baseline of current flow, (2) line irrigation canals to limit seepage losses, (3) increase surface-water diversions through unlined canals for aquifer recharge, (4) convert from surface-water to ground-water resources to supply water for irrigation, and...
Deposition, erosion, and bathymetric change in South San Francisco Bay: 1858-1983
Amy C. Foxgrover, Shawn A. Higgins, Melissa K. Ingraca, Bruce E. Jaffe, Richard E. Smith
2004, Open-File Report 2004-1192
Since the California Gold Rush of 1849, sediment deposition, erosion, and the bathymetry of South San Francisco Bay have been altered by both natural processes and human activities. Historical hydrographic surveys can be used to assess how this system has evolved over the past 150 years. The National Ocean Service...
Content Metadata Standards for Marine Science: A Case Study
Rebecca L. Riall, Fausto Marincioni, Frances L. Lightsom
2004, Open-File Report 2004-1002
The U.S. Geological Survey developed a content metadata standard to meet the demands of organizing electronic resources in the marine sciences for a broad, heterogeneous audience. These metadata standards are used by the Marine Realms Information Bank project, a Web-based public distributed library of marine science from academic institutions and...
Location, Age, and Tectonic Significance of the Western Idaho Suture Zone (WISZ)
Robert J. Fleck, Robert E. Criss
2004, Open-File Report 2004-1039
The Western Idaho Suture Zone (WISZ) represents the boundary between crust overlying Proterozoic North American lithosphere and Late Paleozoic and Mesozoic intraoceanic crust accreted during Cretaceous time. Highly deformed plutons constituted of both arc and sialic components intrude the WISZ and in places are thrust over the accreted terranes. Pronounced...
Publications of the Volcano Hazards Program 2002
Manuel Nathenson
2004, Open-File Report 2004-1047
The Volcano Hazards Program of the U.S. Geological Survey (USGS) is part of the Geologic Hazards Assessments subactivity as funded by Congressional appropriation. Investigations are carried out in the Geology and Hydrology Disciplines of the USGS and with cooperators at the Alaska Division of Geological and Geophysical Surveys, University of...
Chemistry of Stream Sediments and Surface Waters in New England
Gilpin R. Robinson Jr., Katherine E. Kapo, Jeffrey N. Grossman
2004, Open-File Report 2004-1026
Summary -- This online publication portrays regional data for pH, alkalinity, and specific conductance for stream waters and a multi-element geochemical dataset for stream sediments collected in the New England states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. A series of interpolation grid maps portray the chemistry...
Mineral commodity profiles: Cadmium
W. C. Butterman, Jozef Plachy
2004, Open-File Report 2002-238
Overview -- Cadmium is a soft, low-melting-point metal that has many uses. It is similar in abundance to antimony and bismuth and is the 63d element in order of crustal abundance. Cadmium is associated in nature with zinc (and, less closely, with lead and copper) and is extracted mainly as...
Mineral Deposit Data for Epigenetic Base- and Precious-metal and Uranium-thorium Deposits in South-central and Southwestern Montana and Southern and Central Idaho
T. L. Klein
2004, Open-File Report 2004-1005
Metal deposits spatially associated with the Cretaceous Boulder and Idaho batholiths of southwestern Montana and southern and central Idaho have been exploited since the early 1860s. Au was first discovered in placer deposits; exploitation of vein deposits in bedrock soon followed. In 1865, high-grade Ag vein deposits were discovered and...
Bedrock geology and mineral resources of the Knoxville 1° x 2° quadrangle, Tennessee, North Carolina, and South Carolina
Gilpin R. Robinson Jr., Frank G. Lesure, J. I. Marlowe II, Nora K. Foley, S. H. Clark
2004, Open-File Report 2004-1075
The Knoxville 1°x 2° quadrangle spans the Southern Blue Ridge physiographic province at its widest point from eastern Tennessee across western North Carolina to the northwest corner of South Carolina. The quadrangle also contains small parts of the Valley and Ridge province in Tennessee and the Piedmont province in North...
Compilation of Data to Support Development of a Pesticide Management Plan by the Yankton Sioux Tribe, Charles Mix County, South Dakota
Bryan D. Schaap
2004, Open-File Report 2004-1032
The U.S. Environmental Protection Agency is working with the Yankton Sioux Tribe to develop a pesticide management plan to reduce potential for contamination of ground water that may result from the use of registered pesticides. The purpose of this study was to compile technical information to support development of a...
Surveying Cross Sections of the Kootenai River Between Libby Dam, Montana, and Kootenay Lake, British Columbia, Canada
Gary J. Barton, Edward H. Moran, Charles Berenbrock
2004, Open-File Report 2004-1045
The declining population of Kootenai River white sturgeon, which was listed as an Endangered Species in 1994, has prompted a recovery team to assess the feasibility of various habitat enhancement scenarios to reestablish white sturgeon populations. As the first phase in this assessment, the U.S. Geological Survey collected stream channel...
