Least-squares refinement of powder diffraction data for unit cell parameters: Program listing for DEC 10 computer
George Van Trump, Phoebe L. Hauff
1978, Open-File Report 78-431
This FORTRAN computer program is a time-sharing version of the classic program of Appleman and Evans (1973) and Evans, Appleman, and Handwerker (1963), which indexes powder patterns and refines unit-cell dimensions. The program, originally written to be processed in batch mode for an IBM computer, was modified to run in...

A study of fault plane mechanisms preceding the Thanksgiving Day, 1974 earthquake at Hollister, California
David H. Warren
1978, Open-File Report 78-255
Fault plane solutions were obtained for 80 microearthquakes in a 900 square km area centered on the Busch fault during a one year period preceding the Thanksgiving Day, 1974 Hollister earthquake. Strike slip motion occurred in 65 of the quakes, mainly at active spots on the Sargent, Castro, Busch, and...
Update and revision of brachiopod collections of the Phosphoria, Park City, and Shedhorn Formations (Permian) of the U.S. Geological Survey
Bruce R. Wardlaw
1978, Open-File Report 78-692
The numerous collections amassed by the U.S. Geological Survey's study of the Western Phosphate Field have been examined. Many collections already have been discarded; and only those still housed at the Smithsonian are dealt with in this paper. Future studies of the biostratigraphy and paleogeography of the Phosphoria Formation and...

Nuclear power reactor sites in the southeastern United States
Mareta West
1978, Open-File Report 78-256
This report describes nuclear power reactor sites in the southeastern United States. The map indicates the location of all sites as of July 1976 in the conterminous United States, and a later published report will include all sites. The project is one of several in the National Environmental Overview Program...
Mallets Creek Marsh, Lake Champlain: A plant-nutrient study
John T. Turk
1978, Open-File Report 78-462
Nitrogen and phosphorus dissolved in the interstitial water of Mallets Creek Marsh sediments supply about 42 percent of the nitrogen and about 9 percent of the phosphorus used by rooted macrophytes within the marsh. These percentages may become larger during middle and late summer, when water inflow to the marsh...
Floodflow analysis of Ninemile Creek, Onondaga County, New York
Richard Lumia, Bernard Dunn
1978, Open-File Report 78-85
A flood-stage and discharge analysis was made for a 3.61 mile reach of Ninemile Creek between Amboy and Camillus. Water-surface profiles were developed for 50-year, 100-year, and September 26, 1975 flood discharges at Camillus for four different channel conditions: (1) with four culverts at Camillus bypass and a bridge at...
Effects of urban development on the flood-flow characteristics of the Walnut Creek Basin, Des Moines Metropolitan area, Iowa
Oscar G. Lara
1978, Water-Resources Investigations Report 78-11
This report deals with the probable impact of urban development on the magnitude and frequency of flooding in the lower reach of the Walnut creek Basin.Stream-modeling techniques, which include complete definition of unit hydroqraphs and precipitation loss-rate criteria, were utilized to evaluate the effects of urban development as measured by...

1978, Open-File Report 78-239
This report contains lists of streamflow and reservoir stations, peak-flow partial-record stations, chemical-quality stations, sediment stations, and observation wells where water levels are measured in Wyoming. The locations of the basic-data sites are shown on maps. Thirty-two water-resources appraisal projects in Wyoming are also described, including many that are related...
Ground-water availability in the Hayes-Red Willow, Frenchman, and Meeker-Driftwood irrigation districts, southwest Nebraska
E.G. Lappala, P.F. Hemphill, R.E. Booker
1978, Open-File Report 78-461
Surface-water supplies are diminishing in the Hitchcock-Red Willow and Frenchman Valley Irrigation Districts in southwest Nebraska. Stream depletions due to ground-water withdrawals upstream from Enders Reservoir (northwest of the study area) have resulted in a shortage of about 8,700 acre-feet per year. The availability of ground water to supply part...

Monitoring crustal deformation in the Geysers-Clear Lake geothermal area, California
Ben Elder Lofgren
1978, Open-File Report 78-597
Geodetic surveys since 1972-73 reveal significant crustal deformation in The Geysers-Clear Lake region. Resurveys of precise control networks are measuring both vertical and horizontal ground movement, with most of the change continuing in the area of geothermal fluid withdrawal. Preliminary evidence suggests right-lateral horizontal movement on northwest-trending fault systems and...
Regional and local networks of horizontal control, Cerro Prieto geothermal area, Mexico
Bruce L. Massey
1978, Open-File Report 78-929
The Cerro Prieto geothermal area in the Mexicali Valley 30 km southeast of Mexicali, Baja California, is probably deforming due to (1) the extraction of large volumes of steam and hot water, and (2) active tectonism. Two networks of precise horizontal control were established in Mexicali Valley by the U.S....

Joel S. Leventhal, Joan K. Jennings, Alan J. Lemke
1978, Open-File Report 78-235
Samples from Summit County, Colo., were fractionated for analyses of organic content and uranium. The uranium is related to organic content but not to type of organic matter. In one area uranium values are around 100 ppm in bulk samples and as much as 200 ppm in certain separated fractions...
