Joints, fissures, and voids in rhyolite welded ash-flow tuff at Teton damsite, Idaho
Harold J. Prostka
1977, Open-File Report 77-211
Several kinds of joints, fissures, and voids are present in densely welded rhyolite ash-flow tuff at Teton damsite. Older fissures and voids probably were formed in the ash-flow sheet during secondary flowage, which probably was caused by differential compaction or settling over irregular topography. The younger, more abundant fissures are...
Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards
Lynn A. Yehle
1977, Open-File Report 77-272
A program to study the engineering geology of most larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about the Metlakatla area, Annette Island, is a product of that program. Field-study methods were of a reconnaissance nature,...
Water loss from Jordan Creek near Allentown, Pennsylvania - 1973 to 1976
Robert E. Steacy
1977, Open-File Report 77-479
Results of water-loss studies for Jordan Creek near Allentown, Pa. are presented in both tabular and graphical form. The reach studied is approximately 24 miles long and extends from a point near Lowhill, Pa. to a point in Allentown, Pa. The drainage area at Allentown is about 76 square miles....
Electronic thermal sensor and Landsat data collection platform technology
Duane M. Preble, Jules D. Friedman, David Frank
1977, Open-File Report 77-87
Five Data Collection Platforms (DCP) were integrated electronically with thermal sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites. The DCP's transmitted 3260 messages comprising 26,080 ambient, surface, and near-surface temperature records at an accuracy of ±1.15°C for 1121 instrument days between...
Index of published surface-water quality data for Oklahoma 1946-1975
Jerry D. Stoner
1977, Open-File Report 77-204
Surface-water-quality data for Oklahoma have been published by the U.S. Geological Survey in cooperation with various State agencies on an annual basis since 1949. The published data represents 2,733 station-years of data from 527 stations, ranging from one sample from a station once during the thirty--year period to a continuously...
Development of water facilities in the Santa Ana River Basin, California, 1810-1968: a compilation of historical notes derived from many sources describing ditch and canal companies, diversions, and water rights
M.B. Scott
1977, Open-File Report 77-398
This report traces by text, maps, and photographs, the development of the water supply in the Santa Ana River basin from its beginning in 1810 or 1811 to 1968. The value of the report lies in the fact that interpretation of the hydrologic systems in the basin requires knowledge of...
SIPB: a seismic refraction inverse modeling program for batch computer systems
James Henry Scott
1977, Open-File Report 77-366
SIPB is an interactive Fortran computer program that was developed for use with a timeshare computer system with program control information submitted from a remote terminal, and output data displayed on the terminal or printed on a line printer. The program is an upgraded version of FSIPI (Scott, Tibbetts, and...
Electrical resistivity well-logging system with solid-state electronic circuitry
James Henry Scott, Arnold J. Farstad
1977, Open-File Report 77-144
An improved 4-channel electrical resistivity well-logging system for use with a passive probe with electrodes arranged in the 'normal' configuration has been designed and fabricated by Westinghouse Electric Corporation to meet technical specifications developed by the U.S. Geological Survey. Salient features of the system include solid-state switching and current regulation...
National coal resource investigations of the United States Geological Survey
1977, Open-File Report 77-763
The objective of this report is to provide a record of some of the goals and accomplishments of the coal resource investigations of the U. S. Geological Survey for 1977. Successful completion of these goals will aid the Nation in the years ahead because proper usage of coal resource data...
Evaporation and radiation measurements at Salton Sea, California
Alex M. Sturrock
1977, Open-File Report 77-74
Evaporation from the Salton Sea, Calif., was computed for a 539-day period between July 14, 1967, and January 2, 1969, by use of energy-budget, mass-transfer, and water budget methods. The total evaporation computed by the three methods agreed within 5 percent. The values of heat transfer to and from the...
Summary of results of frictional sliding studies, at confining pressures up to 6.98 kb, in selected rock materials
R. Summers, J. Byerlee
1977, Open-File Report 77-142
This report is a collection of stress-strain charts which were produced by deforming selected simuiated fault gouge materials. Several sets of samples consisted of intact cylinders, 1.000 inch in diameter and 2.500 inches long. The majority of the samples consisted of thin layers of the selected sample material, inserted within...
