Ground-water resources in the Lompoc area, Santa Barbara County, California
G.A. Miller
1976, Open-File Report 76-183
Water supplies in the Lompoc plain are pumped from highly permeable gravel and sand, which make up the main water-bearing zone. The history of ground-water quality in the Lompoc area shows little change in the Lompoc upland and the Lompoc terrace, but an increase in the concentration of dissolved solids...

Floods of May-July 1975 Along the Continental Divide in Montana
M. V. Johnson, R. J. Omang
1976, Open-File Report 76-424
Extensive flooding occurred along both sides of the Continental Divide in Montana from May through July 1975. Runoff from above average snowpack at low altitudes combined with runoff from rainfall to cause floods in May. Snowmelt from high altitudes and above average rain in June caused flooding and sustained high...

Hydrologic data for urban studies in the San Antonio, Texas metropolitan area, 1976
Lynn Harmsen
1976, Open-File Report 78-164
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.The Geological Survey, in cooperation with the Texas Department of Water Resources, expanded the existing streamflow network in...

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...
Ground water in Minnesota
Gerald F. Lindholm, Ralph F. Norvitch
1976, Open-File Report 76-354
Ground water is the major source of water supply in Minnesota. The quantity, quality, and availability vary greatly throughout the State. This study describes the State's ground-water resources as found in each of seven major drainage basins. Water is obtained from Quaternary glacial deposits and bedrock aquifers. Most supplies are from...

This report contains rainfall, runoff, and storage data collected during the 1976 water year for a 75.5 sq mi area above the stream-gaging station Little Elm Creek near Aubrey, Texas. Floodflows from 35.7 sq mi of the area are regulated by 16 floodwater-retarding structures constructed by the Soil Conservation Service....
Laboratory manual: mineral X-ray diffraction data retrieval/plot computer program
Phoebe L. Hauff, George Van Trump
1976, Open-File Report 76-407
The Mineral X-Ray Diffraction Data Retrieval/Plot Computer Program--XRDPLT (VanTrump and Hauff, 1976a) is used to retrieve and plot mineral X-ray diffraction data. The program operates on a file of mineral powder diffraction data (VanTrump and Hauff, 1976b) which contains two-theta or 'd' values, and intensities, chemical formula, mineral name, identification...
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...

Geology and ore deposits of the McDermitt Caldera, Nevada-Oregon
James J. Rytuba
1976, Open-File Report 76-535
The McDermitt caldera is a Miocene collapse structure along the Nevada-Oregon border. The oval-shaped caldera is bounded by arcuate normal faults on the north and south and by rhyolite ring domes on the west. Precollapse ash-flow tuffs exposed within the south caldera rim consist of three cooling units and are...
