1982, Open-File Report 82-704
A Schlumberger dc resistivity survey of the Gibson Dome-Lockhart Basin area, San Juan County, Utah, has revealed the following electrical characteristics of the area: (1) the area between the northern part of Davis Canyon and Gibson Dome is electrically quite uniform and resistive at the depth of the Pennsylvanian evaporite...
Determination of ultimate carbonaceous BOD and the specific rate constant (K1)
J. K. Stamer, J. P. Bennett, Stuart W. McKenzie
1982, Open-File Report 82-645
Ultimate carbonaceous biochemical oxygen demand (BODu) and the specific rate constant (K1) at which the demand is exerted are important parameters in designing biological wastewater treatment plants and in assessing the impact of wastewater on receiving streams. An analytical method is presented which uses time-series concentrations of BOD, defined as...
Leaching characteristics of ash from the May 18, 1980, eruption of Mount St. Helens Volcano, Washington

1982, Open-File Report 82-987
Leaching of freshly erupted air-fall ash, unaffected by rain, from the May 18, 1.980,eruption of Mount St. Helens volcano, Washington, shows that Ca 2+, Na+, Mg+, SO4 2-, and Cl- are the predominant chemical species released on first exposure of the ash to water. Extremely high correlation of Ca with...

Reconnaissance of stormwater-runoff water quality of the Big Piney Creek segment of the Cedar-Piney Creeks watershed, Yell County, Arkansas
James C. Petersen
1982, Open-File Report 82-761
A reconnaissance of the Big Piney Creek watershed was made between June 1981 and January 1982 to assess the water quality of selected streams in the watershed. Streamflow was measured and water samples were collected three times at each of three sites during the study. All samples were collected during...

Hydrology of the Floridan Aquifer in Northwest Volusia County, Florida
A. T. Rutledge
1982, Open-File Report 82-108
Northwest Volusia County, in east-central Florida, is a 262-square-mile area including the southern part of the Crescent City Ridge and the northern tip of the DeLand Ridge. The hydrogeologic units in the area include the Floridan aquifer, which is made up of parts of the Lake City Limestone, the Avon...

Sediment and channel-geometry investigations for the Kansas River bank stabilization study, Kansas, Nebraska, and Colorado
W. R. Osterkamp, R.E. Curtis, H.G. Crowther
1982, Open-File Report 81-128
Analysis of hydrologic data from the Kansas River basin suggests that the channels of the lower Solomon, Saline, and Smoky Hill Rivers have narrowed and stabilized as a result of construction of upstream reservoirs. The Kansas River channel, however, remains relatively unstable and locally active. Streamflow regulation and sediment trapping...
Regional geohydrology of the northern Louisiana salt-dome basin; Part I, conceptual model and data needs
G.N. Ryals
1982, Open-File Report 82-343
As part of the National Waste Terminal Storage Program, the U.S. Geological Survey is conducting a regional study of the geohydrology of the northern Louisiana salt-dome basin and developing a regional multi-layered ground-water flow model to determine regional flow paths. In the salt-dome basin the Tokio Formation and Brownstown Marl...

Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...

The mathematical method of determining in-situ stresses by overcoring, using either the U.S. Bureau of Mines Borehole Deformation Gage or the Commonwealth Scientific and Industrial Research Organisation Hollow Inclusion Stress Cell, is summarized, and data reduction programs for each type of instrument, written in BASIC, are presented. The BASIC programs...

A model for the simulation of flow of variable-density ground water in three dimensions under steady-state conditions
Emanuel Weiss
1982, Open-File Report 82-352
A computer program has been developed as part of the U.S. Geological Survey's national program of Regional Aquifer System Analysis (RASA) that generates input to ground-water flow models to enable them to simulate variable-density ground-water flow. Information required for the program's operation is: aquifer elevation, thickness, and ground-water density. Included...
A computer program for calculating relative-transmissivity input arrays to aid model calibration
Emanuel Weiss
1982, Open-File Report 82-447
A program is documented that calculates a transmissivity distribution for input to a digital ground-water flow model. Factors that are taken into account in the calculation are: aquifer thickness, ground-water viscosity and its dependence on temperature and dissolved solids, and permeability and its dependence on overburden pressure. Other factors affecting...
