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...
User's guide to the Radiometric Age Data Bank (RADB)
Robert Eugene Zartman, J. C. Cole, Richard F. Marvin
1976, Open-File Report 76-674
The Radiometric Age Data Bank (RADB) has been established by the U.S. Geological Survey, as a means for collecting and organizing the estimated 100,000 radiometric ages presently published for the United States. RADB has been constructed such that a complete sample description (location, rock type, etc.), literature citation, and extensive...
Heat flow near Charleston, South Carolina
John P. Ziagos, J.H. Sass, Robert J. Munroe
1976, Open-File Report 76-148
As part of a study of the geology and geophysics of the Charleston, South Carolina, area, thermal conductivity, thermal gradient, and heat flow were determined in a 742 meter, continuously cored, test hole. The hole is located 41 km west-northwest of Charleston near Clubhouse Corners, Figure 1, directly over a...
Preliminary investigations on computational methods for solving the two-point seismic ray-tracing problem in a heterogeneous and isotropic medium
J.P. Yang, William Hung Kan Lee
1976, Open-File Report 76-707
Two-point seismic ray tracing is an important problem in seismology. In this report, we study this problem by first deriving the differential equations governing seismic wave propagation between two end points in a 3-dimensional heterogeneous and isotropic medium. We then formulate three numerical schemes to solve the two-point ray-tracing problem....
Maps showing ground-water conditions in the lower Big Chino Valley and Williamson Valley areas, Yavapai and Coconino Counties, Arizona--1975-76
B.L. Wallace, R. L. Laney
1976, Water-Resources Investigations Report 76-78
Arizona is divided into 67 ground-water areas, and individual areas are selected for intensive data collection once every 6 years. The data collected in the lower Big Chino Valley and Williamson Valley areas are given on maps that show depth to water, well depth, and altitude of the water level,...
Preliminary summary of the 1976 Atlantic Margin Coring Project of the U.S. Geological Survey
John Cummins Hathaway, J.J. Schlee, C. W. Poag, P. C. Valentine, Elaine G. A. Weed, Michael H. Bothner, F. A. Kohout, F.T. Manheim, R. Schloam, R.E. Miller, D.M. Schultz
1976, Open-File Report 76-844
The U.S. Geological Survey Atlantic Margin Coring Project, 1976, a 60-day expedition to obtain core samples by drilling beneath the floor of the Continental Shelf and Slope of the eastern United States, was carried out in July, August, and September 1976 aboard D/V GLOMAR CONCEPTION. The coring penetrated as much...
Flood-frequency analysis for small natural streams in Georgia
Harold G. Golden, McGlone Price
1976, Open-File Report 76-511
Flood information from 104 project basins (0.1 to 20 square miles) and data available from 170 larger basins (20 to 1,500 square miles) are analyzed to provide planners and designers with relations for estimating the magnitude and frequency of flood-peak discharges on small natural streams in Georgia. More than 90...
Appraisal of water resources in the Hackensack River basin, New Jersey
L.D. Carswell
1976, Water-Resources Investigations Report 76-74
The Hackensack River basin, in the northern part of the New Jersey-New York metropolitan area, includes some of the most highly urbanized areas in the United States as well as a largely undeveloped 23.4 square mile area of tidal marsh referred to as the Hackensack Meadows. Bedrock in the Hackensack...
Water resources of northwestern Wyoming
Edward Riley Cox
1976, Hydrologic Atlas 558
This 3-sheet map report describes the hydrologic conditions in northwestern Wyoming. The increasing number of tourists and residents and the shifting of overnight accommodations for tourists from Yellowstone and Grand Teton National Parks to nearby areas may result in the need for development of additional water supplies in northwestern Wyoming....
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...
Water resources of south-central Missouri
E. E. Gann, Edward Joseph Harvey, Don E. Miller
1976, Hydrologic Atlas 550
This atlas describes hydrology in an area of approximately 23 ,000 sq mi and includes all or parts of 38 counties in Missouri. The area is bounded on the north by the southern edge of the Missouri River flood plain, on the east by the Mississippi River and the Plateaus-Lowlands...
