Geology of the north end of the Salt Valley Anticline, Grand County, Utah
Leonard Meade Gard
1976, Open-File Report 76-303
This report describes the geology and hydrology of a portion of the Salt Valley anticline lying north of Moab, Utah, that is being studied as a potential site for underground storage of nuclear waste in salt. Selection of this area was based on recommendations made in an earlier appraisal of...
Floods of May-July 1975 Along the Continental Divide in Montana
M. V. Johnson, R. J. Omang
1976, Open-File Report 76-424
Extensive flooding occurred along both sides of the Continental Divide in Montana from May through July 1975. Runoff from above average snowpack at low altitudes combined with runoff from rainfall to cause floods in May. Snowmelt from high altitudes and above average rain in June caused flooding and sustained high...
Distribution functions for statistics derived from bivariate normal and bivariate two-parameter log-normal populations
James Richard Slack, Nicholas C. Matalas, James R. Wallis
1976, Open-File Report 76-214
The distribution functions for hydrologic statistics that may be used to assess the significance of differences between sample means, standard deviations, coefficients of skewness, and coefficients of variations are obtained by Monte Carlo experiments. The distributions are expressed as functions of sample size, cross correlation, and skewness. In general, the...
Preliminary space image lineament maps of Alaska
Ernest Hartwell Lathram, Robert G.H. Raynolds
1976, Open-File Report 76-341
Examination of images from Nimbus, NOAA and Landsat satellites has revealed a series of lineaments in the earth's surface in Alaska 1000 km or more in length (fig. 1). These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences...
A brief hydrologic appraisal of the July 3-4, 1975, flash flood in Las Vegas Valley, Nevada
T. L. Katzer, Patrick A. Glancy, Lynn Harmsen
1976, Open-File Report 76-100
Heavy thunderstorm precipitation on the afternoon of July 3, 1975, between metropolitan Las Vegas and the mountains to the south, west, and north, caused flash flooding in the city area. Total storm precipitation equaled or exceeded 3 inches (76 mm) in some areas. The total storm yield on the area...
The effects of ground-water development on the water supply in the Post Headquarters area, White Sands Missile Range, New Mexico
T. E. Kelly, Glenn A. Hearne
1976, Open-File Report 76-277
Water-level declines in the Post Headquarters area, White Sands Missile Range, N. Mex., have been accompanied by slight but progressive increases in the concentration of dissolved solids in water withdrawn from the aquifer. Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet...
Flood discharges of streams in New Mexico as related to channel geometry
Arthur G. Scott, J.L. Kunkler
1976, Open-File Report 76-414
This report describes the results of a study relating flood characteristics to the reference width of the channel.Data from 79 gaging stations, which would provide estimates of floods of a 10-year recurrence interval and at which channel geometry could be adequately measured in the field, were used in these analyses....
Tests of the standard (30 hz) NCER FM multiplex telemetry system, augmented by two timing channels and a compensation reference signal, used to record multiplexed seismic network data on magnetic tape
Jerry P. Eaton
1976, Open-File Report 76-374
The application of subtractive compensation to USGS seismic magnetic tape recording and playback systems was examined in a recent USGS Open-file report (1). It was found, for the standard (30 Hz) NCER multiplex system, that subtractive compensation utilizing a 4688 Hz reference signal multiplexed onto each data track was more...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
Geology and ore deposits of the McDermitt Caldera, Nevada-Oregon
James J. Rytuba
1976, Open-File Report 76-535
The McDermitt caldera is a Miocene collapse structure along the Nevada-Oregon border. The oval-shaped caldera is bounded by arcuate normal faults on the north and south and by rhyolite ring domes on the west. Precollapse ash-flow tuffs exposed within the south caldera rim consist of three cooling units and are...
Ground water in Minnesota
Gerald F. Lindholm, Ralph F. Norvitch
1976, Open-File Report 76-354
Ground water is the major source of water supply in Minnesota. The quantity, quality, and availability vary greatly throughout the State. This study describes the State's ground-water resources as found in each of seven major drainage basins. Water is obtained from Quaternary glacial deposits and bedrock aquifers. Most supplies are from...
