Effects of local geology on ground motion in the San Francisco Bay region, California: A continued study
James F. Gibbs, Roger D. Borcherdt
1974, Open-File Report 74-222
Measurements of ground motion generated by nuclear explosions in Nevada have been completed for 99 locations in the San Francisco Bay region, California. The seismograms, Fourier amplitude spectra, spectral amplification curves for the signal, and the Fourier amplitude spectra of the seismic noise are presented for 60 locations. Analog amplifications,...
Selenium, fluorine, and arsenic in surficial materials of the conterminous United States
Hansford T. Shacklette, Josephine G. Boerngen, John R. Keith
1974, Circular 692
Concentrations of selenium, fluorine, and arsenic in 912, 911, and 910 samples, respectively, of soils and other regoliths from sites approximately 50 miles (80 km) apart throughout the United States are represented on maps by symbols showing five ranges of values. Histograms of the concentrations of these elements are also...
A method for the relative classification of lakes in the State of Washington from reconnaissance data
Gilbert Carl Bortleson, N. P. Dion, James B. McConnell
1974, Water-Resources Investigations Report 74-37
The classification system developed allows a rapid assessment of the eutrophic potential and condition of more than 750 Washington lakes and reservoirs. The potential for nutrient enrichment from natural sources is evaluated on the basis of the interactions of physical and hydrologic factors that play a role in controlling the...
Antimony and other metal anomalies south of Stibnite, Valley County, Idaho
Gary C. Curtin, Harley D. King, B. F. Leonard
1974, Open-File Report 74-111
Results of geochemical investigations south of Stibnite, Valley County, Idaho, show that the distribution of Sb, As, Au, Zn, Ag, and Mo in mull ash and of Hg, in soil forms a highly anomalous area which is more than 1.5 km long and 1 km wide along the trace of...
Grid-coordinate generation program
Oliver J. Cosner, Esther Horwich
1974, Open-File Report 74-1018
This program description of the grid-coordinate generation program is written for computer users who are familiar with digital aquifer models. The program computes the coordinates for a variable grid -used in the 'Pinder Model' (a finite-difference aquifer simulator), for input to the CalComp GPCP (general purpose contouring program). The program...
Empirical data on longitudinal dispersion in rivers
Carl F. Nordin, George V. Sabol
1974, Water-Resources Investigations Report 74-20
Empirical data on longitudinal dispersion process in rivers are compiled from published and unpublished sources. Fifty-one sets of data, covering flows from about 30 cubic feet per second to 241,000 cubic feet per second (0.85 to 6,820 cubic meters per second), are analyzed graphically....
