Annual summary of ground-water conditions in Arizona, spring 1975 to spring 1976
H. M. Babcock
1977, Water-Resources Investigations Report 77-10
Two small-scale maps of Arizona show (1) pumpage of ground water by areas and (2) the status of the ground-water inventory in the State. A larger map of the State at a scale of 1:500,000 shows potential well production, depth to water in selected wells in spring 1976, and change...
Seismicity map of the State of Maine
Carl W. Stover, B. Glen Reagor, Barbara B. Poppe
1977, Miscellaneous Field Studies Map 845
The earthquake data for the state of Maine shown on this map and listed in table 1 was taken from the U.S. Geological Survey catalog of earthquakes (Hays, and others, 1975).  This list of earthquakes was originally compiled for use in preparing the Seismic Risk Studies in the United States...
Preliminary evaluation of flood frequency relations in the urban areas of Memphis, Tennessee
Charles W. Boning
1977, Water-Resources Investigations Report 77-132
A storm-runoff relation for streams in the urban areas of Memphis was determined by a statistical evaluation of 59 flood discharges from 19 gaging stations. These flood discharges were related to drainage area, percent imperviousness of the drainage basin, and rainfall occuring over 120-minute periods. The defined relation is Q=m3A*777A...
Short papers of the U.S. Geological Survey Uranium-Thorium Symposium, 1977
John A. Campbell, editor(s)
1977, Circular 753
This circular contains expanded abstracts for the technical papers presented at the 1977 Uranium and Thorium Research and Resources Conference, sponsored by the Branch of Uranium and Thorium Resources, U.S. Geological Survey. This Conference was held April 27 and 28, 1977, at the Colorado School of Mines, Golden. This was...
Paleozoic-Mesozoic boundary in the Berry Creek Quadrangle, northwestern Sierra Nevada, California
Anna Martta Hietanen
1977, Professional Paper 1027
Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees...
Techniques for estimating flood discharges for Oklahoma streams; Techniques for calculating magnitude and frequency of floods in Oklahoma from rural and urban areas under 2500 square miles, with compilations of flood data through 1975
Wilbert O. Thomas Jr., Robert K. Corley
1977, Water-Resources Investigations Report 77-54
Statewide regression equations are defined for estimating peak discharges of floods having recurrence intervals ranging from 2 to 500 years. Contributing drainage area, main-channel slope and mean annual precipitation are the independent variables required for estimating flood discharges for rural streams. For urban streams the percentage of the basin that...
Reconnaissance of ground-water resources in the Mountain Home plateau area, southwest Idaho
H.W. Young
1977, Water-Resources Investigations Report 77-108
The Mountain Home plateau area occupies approximately 1,220 square miles of the western Snake River Plain in southwestern Idaho. About 40,000 acres are presently (1977) irrigated with ground water, about 30,000 acres with surface water. An estimated 450,000 acres are potentially irrigable, if water is available. Development of ground-water re-sources...
Physical, chemical, and biological relations of four ponds in the Hidden Water Creek strip-mine area, Powder River Basin, Wyoming
David J. Wangsness
1977, Water-Resources Investigations Report 77-72
The Hidden Water Creek area in Wyoming was mined from 1944 to 1955 and abandoned. The open pits filled with water and pond-type ecosystems developed. Light was transmitted to greater depths within two control ponds located outside the mine area. The lower light transmittance in the ponds within the mined...
Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...
Preliminary data on some Precambrian deposits of zinc-copper-lead sulfides and zinc spinel (granite) in Colorado
Douglas M. Sheridan, William H. Raymond
1977, Open-File Report 77-607
Precambrian sulfide deposits in the Southern Rocky Mountains in Colorado are being studied and re-evaluated according to geologic concepts which were developed in recent years in other parts of the world during successful research regarding economic massive sulfide deposits. These studies, initiated in 1974 in Colorado by the U.S. Geological...
