McGlone Price
1975, Open-File Report 75-332
The May 1974 U.S. Geological Survey open-file report 75-46, "Cedar Creek at Cedartown, Georgia, Floodflow Characteristics at Georgia Avenue, Relocation and Canal Street Extension," prepared at the request of the Georgia Department of Transportation, described the hydraulic characteristics of the Georgia Avenue relocation as constructed in April 1974, and evaluated...
Interim report on petroleum resource potential and geologic hazards in the outer continental shelf of the Gulf of Alaska Tertiary province
George Plafker, Terry R. Bruns, Robert A. Page
1975, Open-File Report 75-592
The potential for discovering large accumulations of petroleum on the Outer Continental Shelf of the Gulf of Alaska Tertiary Province cannot be evaluated with much confidence at present because of the inadequacies of the available offshore geological and geophysical data. The 22 deep test wells that have been drilled since...
Gravity map of the Nabesna Quadrangle, Alaska
David F. Barnes, Robert L. Morin
1975, Miscellaneous Field Studies Map 655-I
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of...

Aluminum resources of Brazil
Max Gregg White
1975, Open-File Report 75-30
Large deposits of bauxite, the principal ore of aluminum, occur at several places in Brazil. The largest deposits now undergoing extensive exploration and development are in the eastern Amazon Basin. Most of these deposits are in the State of Para, but some are in Amazonas and Maranhao.Discovery of large-scale resources...

Computer program to simulate the salt balance between the north and south parts of Great Salt Lake, Utah
K.M. Waddell, E.L. Bolke
1975, Open-File Report 75-131
This report presents a computer simulation program that was used by Waddell and Bolke (1973) to predict the salt balance between the north and south parts of Great Salt Lake, Utah, for either existing or modified culvert openings (fig. 1). The development of the program, its accuracy and limitations, are...

Self-calibrating seismic amplifier and telemetry system
John R. Van Schaack
1975, Open-File Report 75-64
A frequency modulated, constant bandwidth, telemetry system has been designed to transmit simultaneously up to 8 channels of seismograph data from remote locations to a central recording site via radio or voice-grade telephone circuit. By utilizing state-of-the-art integrated circuits, the size of the remote unit has been considerably reduced over...

Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults
Roger D. Borcherdt, James F. Gibbs, Kenneth R. Lajoie
1975, Miscellaneous Field Studies Map 709
This map shows maximum earthquake intensity predicted at specific sites using the empirical relations derived from the reliable 1906 intensity data (figs. 3 and 4; see text). The numbers 4-0 correspond to letters A-E, respectively, of the San Francisco intensity scale. The predicted intensity value shown for each site is...

Floodflow characteristics at proposed bridge sites on Mohawk River, Whitesboro, New York
Bernard Dunn
1975, Open-File Report 75-442
An evaluation of floodflow characteristics at the proposed bridge site revealed that:1.The design-flood discharge for the proposed bridge site would be 18,200 cubic feet per second (515 cubic metres per second), which is about equal to the discharge for the 100-year flood.2.The elevation at the bridge site for the flood...
