Assay for uranium and determination of disequilibrium by means of in situ high resolution gamma-ray spectrometry
Allan B. Tanner, Robert M. Moxham, F. E. Senftle
1977, Open-File Report 77-571
Two sealed sondes, using germanium gamma-ray detectors cooled by melting propane, have been field tested to depths of 79 m in water-filled boreholes at the Pawnee Uranium Mine in Bee Co., Texas. When, used as total-count devices, the sondes are comparable in logging speed and counting rate with conventional scintillation...
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...
GEOTHERM user guide
James R. Swanson
1977, Open-File Report 77-504
GEOTHERM is a computerized geothermal resources file developed by the U.S. Geological Survey. The file contains data on geothermal fields, wells, and chemical analyses from the United states and international sources. The General Information Processing System (GIPSY) in the IBM 370/155 computer is used to store and retrieve data. The...
Techniques for estimating magnitude and frequency of floods in Minnesota
Lowell C. Guetzkow
1977, Water-Resources Investigations Report 77-31
 Estimating relations have been developed to provide engineers and designers with improved techniques for defining flow-frequency characteristics to satisfy hydraulic planning and design requirements. The magnitude and frequency of floods up to the 100-year recurrence interval can be determined for most streams in Minnesota by methods presented. By multiple regression...
The use of Galerkin finite-element methods to solve mass-transport equations
David B. Grove
1977, Water-Resources Investigations Report 77-49
The partial differential equation that describes the transport and reaction of chemical solutes in porous media was solved using the Galerkin finite-element technique. These finite elements were superimposed over finite-difference cells used to solve the flow equation. Both convection and flow due to hydraulic dispersion were considered. Linear and Hermite...
Water resources data for California; water year 1975; Volume 2: Pacific Slope basins from Arroyo Grande to Oregon State line except Central Valley
Water Resources Division, U.S. Geological Survey
1977, Water Data Report CA-75-2
Water-resources data for the 1975 water year for California consist of records of streamflow and contents of reservoirs at gaging stations, partial-record stations, and miscellaneous sites; records of water quality including the physical, chemical, and biological characteristics of surface and ground water; and records of water levels in selected observation...
