Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part I, Results of the measurements
M. E. Gettings, Abdullah Showail
1982, Open-File Report 82-793
Heat-flow measurements were made at five onland shot points of the 1978 Saudi Arabian seismic deep-refraction line, which sample major tectonic elements of the Arabian Shield along a profile from Ar Riyad to the Farasan Islands. Because of the pattern drilling at each shot point, several holes (60 m deep)...
Aquifer test results, Green Swamp area, Florida
C. H. Tibbals, Hayes F. Grubb
1982, Water-Resources Investigations Report 82-35
An aquifer test conducted in the Green Swamp area December 15-16 , 1975 was designed to stress the uppermost part of the Floridan aquifer so that the leakage characteristics of the overlying confining bed could be determined. A well tapping the upper part of the Floridan aquifer was pumped at...
Techniques for estimating flood discharges for unregulated streams in New Mexico
Richard P. Thomas, Robert L. Gold
1982, Water-Resources Investigations Report 82-24
Equations for estimating flood magnitudes at selected recurrence intervals from 2 to 500 years were developed using multiple-regression analyses. These equations relate flood magnitudes to basin characteristics, contributing drainage area and site altitude, and only are applicable to unregulated streams in New Mexico that are relatively unaffected by urban runoff....
A computer program for calculating relative-transmissivity input arrays to aid model calibration
Emanuel Weiss
1982, Open-File Report 82-447
A program is documented that calculates a transmissivity distribution for input to a digital ground-water flow model. Factors that are taken into account in the calculation are: aquifer thickness, ground-water viscosity and its dependence on temperature and dissolved solids, and permeability and its dependence on overburden pressure. Other factors affecting...
Chloride Concentration in Water from the Upper Permeable Zone of the Tertiary Limestone Aquifer System, Southeastern United States
Craig L. Sprinkle
1982, Water-Resources Investigations Report 81-1103
INTRODUCTION The tertiary limestone aquifer system of the southeastern United States is a sequence of carbonate rocks referred to as the Floridan aquifer in Florida and the principal artesian aquifer in Georgia, Alabama, and South Carolina. More than 3 billion gallons of water are pumped daily from the limestone aquifer; and...
Proceedings of the Second Joint Meeting of the U.S.-Japan Conference on Natural Resources (UJNR) Panel on Earthquake Prediction Technology, July 13-17, 1981
David P. Hill, Keiji Nishimura
1982, Open-File Report 82-180
The Second Joint Meeting of the UJNR Panel on Earthquake Prediction Technology was held at the U.S. Geological Survey facilities in Menlo Park, California, during the week of July 13, 1981. This panel, which was established in 1978, is the newest of 17 panels under the United States/Japan Cooperative Program...
Diatremes of the Hopi Buttes, Arizona; chemical and statistical analyses
K. J. Wenrich, J. F. Mascarenas
1982, Open-File Report 82-740
Lacustrine sediments deposited in maar lakes of the Hopi Buttes diatremes are hosts for uranium mineralization of as much as 1500 ppm. The monchiquites and limburgite turfs erupted from the diatremes are distinguished from normal alkalic basalts of the Colorado Plateau by their extreme silica undersaturation and high water, TiO2,...
Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Characteristics of suspended sediment in the San Juan River near Bluff, Utah
K. R. Thompson, J. C. Mundorff
1982, Water-Resources Investigations Report 82-4104
Fluvial-sediment data were collected for the San Juan River near Bluff beginning in 1914 and terminating in 1980. A double-mass curve showed a change in relationship between annual suspended-sediment discharge and annual stream discharge between the water years 1941-44 and 73. Possible causes for these changes in laboratory procedures, and...
The depositional environment and petrology of the White Rim Sandstone Member of the Permian Cutler Formation, Canyonlands National Park, Utah
B. A. Steele-Mallory
1982, Open-File Report 82-204
The White Rim Sandstone Member of the Cutler Formation of Permian age in Canyonlands National Park, Utah, was deposited in coastal eolian and associated interdune environments. This conclusion is based on stratigraphic relationships primary sedimentary structures, and petrologic features. The White Rim consists of two major genetic units. The first...
Water resources data Iowa, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report IA-81-1
This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of 0. G. Lara, Acting District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other agencies. This report is...
