Modeling coliform-bacteria concentrations and pH in the salt-wedge reach of the Duwamish River Estuary, King County, Washington
W.L. Haushild, Edmund A. Prych
1976, Open-File Report 76-415
Total- and fecal-coliform bacteria, plus pH, alkalinity, and dissolved inorganic carbon are water-quality parameters that have been added to an existing numerical model of water quality in the salt-wedge reach of the Duwamish River estuary in Washington. The coliform bacteria are modeled using a first-order decay (death) rate, which is...

Lineaments on Skylab photographs: detection, mapping and hydrologic significance in central Tennessee
Gerald K. Moore
1976, Open-File Report 76-196
Lineaments were detected on SKYLAB photographs by stereo viewing , projection viewing, and composite viewing. Large well yields of 25 gal/min or more can be obtained in the study area by locating future wells on SKYLAB lineaments rather than on lineaments detected on either high-altitude aerial photographs, LANDSAT images, or...

Preliminary investigation of faults and folds along the inner edge of the coastal plain in northeastern Virginia
Robert B. Mixon, Wayne L. Newell
1976, Open-File Report 76-330
Four en-echelon northeast-trending structures, including southeast-dipping monoclines and northwest-dipping high-angle reverse-faults, have been mapped along the inner edge of the Coastal Plain in northeastern Virginia -- an area generally considered to be undeformed. Although displacements are small (15to 60 m), the structures markedly affect the present distribution and thickness of...
Geothermal investigations in Idaho, Part IV, Isotopic and geochemical analyses of water from the Bruneau-Grand View and Weiser areas, Southwest Idaho
Craig T. Rightmire, H.W. Young, R.L. Whitehead
1976, Open-File Report 76-166
Variations of deuterium and oxygen-18 concentrations in thermal ground waters and local nonthermal springs have been used to aid in describing the source of recharge in the Bruneau-Grand View and Weiser areas, southwest Idaho. Isotope and geochemical data for the Bruneau-Grand View area suggest that recharge to the area may...
15/16 ips Operation of the Precision Instrument Company Model P15100 tape recorder to record the standard (30 Hz) NCER seismic data multiplex system
Jerry P. Eaton
1976, Open-File Report 76-252
In recent months the need has arisen to record special seismic networks consisting of a dozen or more standard NCER seismic systems telemetered to a central collection point on a reliable, portable, low-power tape recorder. Because of its simplicity and the ease with which it can be adapted for the...

Heat flow and near-surface radioactivity in the Australian continental crust
J.H. Sass, J.C. Jaeger, Robert J. Munroe
1976, Open-File Report 76-250
Heat-flow data have been obtained at 44 sites in various parts of Australia. These include seven sites from the old (~ 2500 m.y.) Precambrian shield of Western Australia, seventeen from the younger (~ 600- 2000 m.y.) Precambrian rocks of South Australia, the Northern Territory, and Queensland, and twenty within the...

Time-of-travel studies, Susquehanna River, Binghamton, New York, to Clarks Ferry, Pennsylvania
C.D. Kauffman, J.T. Armbruster, Andrew Voytik
1976, Open-File Report 76-247
Results of time-of-travel studies are presented in both tabular and graphical form for several flow conditions in the Susquehanna River from Binghamton, N.Y., to Clarks Ferry, Pa. This reach is approximately 240 miles (386 kilometres) long, measured along the center of the channel, and has a drainage area of about...
Economic worth of hydrologic data in project design: An application to regional energy development
M.R. Karlinger
1976, Open-File Report 76-316
The linkage between the benefits to a regional economy from a water-dependent industry and the statistical uncertainty of the water supply that is needed in the production process is analyzed using a Bayesian scheme of expected-expected benefits of hydrologic data. In this analysis, expected benefits are calculated using anticipated streamflow...
Principal facts for gravity stations in the Nevada portion of the Mariposa 2 degrees sheet
D.L. Healey
1976, Open-File Report 76-58
The northeast corner of the Mariposa 2° topographic sheet occurs within the State of Nevada (fig. 1) and includes parts of Mineral and Esmeralda Counties. In this area field crews of the U.S. Geological Survey have established 95 gravity observations in conjunction with geologic studies being made as part of...

Occurrence and distribution of color and hydrogen sulfide in water of the principal artesian aquifers in the Valdosta area, Georgia
Richard E. Krause
1976, Open-File Report 76-378
Hydrogen sulfide and color occur in objectionable amounts in ground water from the principal artesian aquifer in the Valdosta , Ga., area. Generally, water from wells south of Valdosta is high in hydrogen sulfide; water from wells north of the city is high in color. Water with high sulfate is...
