Water levels in artesian and nonartesian aquifers of Florida, 1975-76
Henry G. Healy
1978, Open-File Report 78-458
From May 1975 through May 1976, water levels in the Floridan aquifer through most of north and central peninsular Florida declined 2 to 4 feet, on the basis of water-level measurements in 664 wells. These 664 were selected from a network of about 2,100 observation wells for which water-level measurements...
Geology of the uranium prospect at Camp Smith, New York, with a new model for the formation of uranium deposits in metamorphosed submarine volcanogenic rocks
Richard I. Grauch
1978, Open-File Report 78-949
Uraninite of Precambrian age occurs locally in and around a massive sulfide deposit at Camp Smith, Westchester and Putnam Counties, New York. The host rocks are believed to be part of a sequence of marine sediments and submarine volcanogenic rocks that were metamorphosed to leucogneisses, amphibolites, and amphoholite gneisses in...
Terrain-analysis procedures for modeling radar backscatter
Gerald G. Schaber, Richard J. Pike, Graydon Lennis Berlin
1978, Open-File Report 79-1088
The collection and analysis of detailed information on the surface of natural terrain are important aspects of radar-backscattering modeling. Radar is especially sensitive to surface-relief changes in the millimeter- to-decimeter scale four conventional K-band (~1-cm wavelength) to L-band (~25-cm wavelength) radar systems. Surface roughness statistics that characterize these changes in...
Allocation of subsamples of Apollo 17 lunar rocks from the boulder at station 7, for study by the International Consortium
Jean A. Minkin, Carolyn L. Thompson, E. C. T. Chao
1978, Open-File Report 78-511
The International Consortium was organized, under the leadership of E. C. T. Chao, to conduct a systematic interdisciplinary study of four lunar rock samples (77135, 77115, 77075 and 77215) collected by the Apollo 17 astronauts as representative of the four lithologies they recognized in the boulder at station 7. Tables...
Hydrologic data for North Creek, Trinity River basin, Texas, 1976
C.C. Kidwell
1978, Open-File Report 77-732
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing structures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...
Methodology of determining the uncertainty in the accessible geothermal resource base of identified hydrothermal convection systems
Manuel Nathenson
1978, Open-File Report 78-1003
In order to quantify the uncertainty of estimates of the geothermal resource base in identified hydrothermal convection systems, a methodology is presented for combining estimates with uncertainties for temperature, area, and thickness of a geothermal reservoir into an estimate of the stored energy with uncertainty. Probability density functions for temperature,...
Analyses and description of geochemical samples, Craggy Mountain Wilderness Study area, Buncombe County, North Carolina
Jerry M. Motooka, John D. Sharkey, Frank Gardner Lesure
1978, Open-File Report 78-856
Semiquantitative spectrographic analyses for 30 elements and atomic absorption analyses for gold and zinc on 24 bulk stream sediments, 22 panned concentrates, and 50 rock samples from the Craggy Mountain Wilderness Study area and vicinity, Buncombe County, North Carolina, are reported here in detail. Locations for all samples are given...
Summary of the water resources of Puerto Rico
H.J. McCoy
1978, Open-File Report 78-971
The U.S. Department of Commerce (DOC) is the lead agency in the Federal Interagency Study of the Economy of Puerto Rico. At the request of DOC the U.S. Geological Survey is providing a discussion of the water resources of the island for inclusion in the study's section on macroeconomic assessment.Two...
A computer program for simulating salinity loads in streams
Kent C. Glover
1978, Open-File Report 78-884
A FORTRAN IV program that simulates salinity loads in streams is described. Daily values of stream-discharge in cubic feet per second, or stream-discharge and specific conductance in micromhos, are used to estimate daily loads in tons by one of five available methods. The loads are then summarized by computing either...
Minor and trace element contents of kimberlites of the Front Range, Colorado and Wyoming
M. E. McCallum, C.B. Smith
1978, Open-File Report 78-1011
Since 1960 about 90 separate occurrences of kimberlite have been discovered in the Front Range of northern Colorado and southern Wyoming, and in the Laramie Range, Wyoming (e.g., McCallum, Eggler, and Burns, 1975; McCallum, Eggler, Coopersmith, Smith, and Mabarak, 1977; Smith and others, 1977 and in press). All but two...
Hydrologic information for land-use planning, Fairbanks vicinity, Alaska
Gordon L. Nelson
1978, Open-File Report 78-959
The flood plain on the Chena and Tanana Rivers near Fairbanks, Alaska, has abundant water in rivers and in an unconfined alluvial aquifer. The principal source of ground water is the Tanana River, from which ground water flows northwesterly to the Chena River. Transmissivity of the aquifer commonly exceed 100...
Analysis of urban storm-water quality for seven basins near Portland, Oregon
Timothy L. Miller, Stuart W. McKenzie
1978, Open-File Report 78-662
Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment...
