Estimation of ground motion parameters
David M. Boore, W. B. Joyner, A.A. Oliver, R.A. Page
1978, Circular 795
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. A subset of the data (from the San Fernando earthquake) is used to...
Water-quality records for the Hubbard Creek watershed, Texas, October 1974 - September 1976
Helen J. Davidson
1978, Open-File Report 78-98
The U.S. Geological Survey, in cooperation with the West Central Texas Municipal Water District and the Texas Department of Water Resources, is conducting a continuing program to determine the chemical quality of surface waters in the Hubbard Creek watershed. This report provides a compilation of the records for the period...
1978 Water Quality Laboratory services catalog
Linda C. Friedman
1978, Open-File Report 78-502
The information in this catalog is provided to assist field personnel in the selection of determinations, the estimation of costs, the calculation of sample volume requirements, the identification of the necessary sample treatment and in the evaluation of the precision of the laboratory data. The major section of the catalog...
Tin and related elements in sediments and beach sands from Afghanistan, Iran, and Turkey
J. A. Domenico, W.C. Overstreet, A.E. Hubert, R. B. Tripp
1978, Open-File Report 79-1188
Sixty samples of sediments from stream beds, outwash plains, and beaches were collected in Afghanistan, Iran, and Turkey by Fred L. Klinger,U.S. Bureau of Mines, as part of the field work undertaken by the National Geographic-Smithsonian Pyrotechnological Expedition of 1968. Facilities for the analysis of the samples for tin and...
A statistical summary and listing of the spectrographic analyses of heavy mineral concentrate and conventional, sieved stream-sediment samples, Silver City area, New Mexico
K. C. Watts, J.R. Hassemer, D. F. Siems, J. M. Nishi
1978, Open-File Report 78-801
Geochemical sampling of a tier of eight 7 1/2-minute quadrangles bordered by latitudes 32° 45'and 33° 00' N. and longitudes 108° 00' and 108° 30' W. was begun in the fall of 1974 and continued seasonally until completion in the fall of 1976. These quadrangles are in southwest New Mexico...
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...
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...
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,...
Hydrogeologic maps of proposed flood detention area proposed by Southwest Florida Water Management District, Green Swamp area, Florida
A. T. Rutledge, Hayes F. Grubb
1978, Open-File Report 78-460
Information about the hydrogeology of that part of the Green Swamp area which has been designated by Southwest Florida Water Management District as the flood detention area is given on seven maps. The maps show (1) core-hole numbers, (2) sand thickness, (3) clay thickness, (4) clay vertical hydraulic conductivity, (5)...
Backwater at bridges and densely wooded flood plains, Bogue Chitto near Summit, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1978, Hydrologic Atlas 592
New techniques for predicting water-surface profiles, needed in the design of economical, structurally sound, and environmentally compatible stream crossings, are under investigation.  The investigation has accelerated with the advent of digital computers capable of analyzing large quatities of data.  Among the techniques is the development of two-dimensional (2-D) digital models....
