Documentation of programs that compute 1) quasi-static tilts produced by an expanding dislocation loop in an elastic and viscoelastic material, and 2) surface shear stresses, strains, and shear displacements produced by screw dislocations in a vertical slab with modulus contrast
Stuart McHugh
1976, Open-File Report 76-484
The material in this report can be grouped into two categories: 1) programs that compute tilts produced by a vertically oriented expanding rectangular dislocation loop in an elastic or viscoelastic material and 2) programs that compute the shear stresses, strains, and shear displacements in a three-phase half-space (i.e. a half-space...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
In-situ measurements of seismic velocities in the San Francisco Bay region...Part II

1976, Open-File Report 76-731
Seismic wave velocities (compressional and shear) are important parameters for determining the seismic response characteristics of various geologic units when subjected to strong earthquake ground shaking.Seismic velocities of various units often show a strong correlation with the amounts of damage following large earthquakes and have been used as a basis...

Chemical characteristics of the major thermal springs of Montana
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-480
Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most...
A brief hydrologic appraisal of the July 3-4, 1975, flash flood in Las Vegas Valley, Nevada
T. L. Katzer, Patrick A. Glancy, Lynn Harmsen
1976, Open-File Report 76-100
Heavy thunderstorm precipitation on the afternoon of July 3, 1975, between metropolitan Las Vegas and the mountains to the south, west, and north, caused flash flooding in the city area. Total storm precipitation equaled or exceeded 3 inches (76 mm) in some areas. The total storm yield on the area...
Distribution functions for statistics derived from bivariate normal and bivariate two-parameter log-normal populations
James Richard Slack, Nicholas C. Matalas, James R. Wallis
1976, Open-File Report 76-214
The distribution functions for hydrologic statistics that may be used to assess the significance of differences between sample means, standard deviations, coefficients of skewness, and coefficients of variations are obtained by Monte Carlo experiments. The distributions are expressed as functions of sample size, cross correlation, and skewness. In general, the...

The Lisburne Group: A potential major hydrocarbon objective of the Arctic Slope, Alaska
Kenneth J. Bird, Clifton F. Jordan
1976, Open-File Report 76-786
The Lisburne Group, a thick carbonate rock unit of Mississippian and Pennsylvanian age, is one of the most widespread potential reservoir rock units in northern Alaska. A comprehensive review of the Lisburne in the subsurface of the eastern Arctic Slope indicates attractive reservoir characteristics in a favorable source and migration...

Thermographic mosaic of Yellowstone National Park
Richard S. Williams Jr., Philip G. Hasell Jr., Albert N. Sellman, Harry W. Smedes
1976, Photogrammetric Engineering and Remote Sensing (42) 1315-1324
An uncontrolled thermographic mosaic, which covers most of the area of Yellowstone National Park, has been compiled. The recording of aerial thermographic data on videotape is established as one of the prerequisites for the preparation of more accurate mosaics. Post-mission processing of the videotape record can rectify the nadir line...
A qualitative evaluation of Landsat imagery of Australian rangelands

1976, The Australian Rangeland Journal (1) 53-59
The capability of multidate, multispectral ERTS-1 imagery of three different rangeland areas within Australia was evaluated for its usefulness in preparing inventories of rangeland types, assessing on a broad scale range condition within these rangeland types, and assessing the response of rangelands to rainfall events over large areas. For the...

The survival of coho salmon (Oncorhynchus kisutch) eggs in two Wisconsin tributaries of Lake Michigan
James E. Cloern
1976, American Midland Naturalist (96) 451-461
Natural reproduction of coho salmon (Oncorhynchus kisutch) in two Wisconsin tributaries of Lake Michigan (Little Scarboro Creek, Kewaunee Co., and Fischer Creek, Manitowoc Co.), is limited by an unusually high mortality of eggs and preemergent embryos. Of approximately 1800 coho salmon eggs planted in six study redds (spawning beds) within...
