Geologic studies in Alaska by the U.S. Geological Survey during 1987
John P. Galloway, Thomas D. Hamilton, editor(s)
1988, Circular 1016
This volume is a continuation of the annual United States Geological Survey (USGS) Circulars reporting results of work in progress on earth science investigations in Alaska. The series began in 1975 under the title "The United States Geological Survey in Alaska - Accomplishments during 19xx" and has continued since 1986...
A modular three-dimensional finite-difference ground-water flow model
Michael G. McDonald, Arlen W. Harbaugh
1988, Techniques of Water-Resources Investigations 06-A1
This report presents a finite-difference model and its associated modular computer program. The model simulates flow in three dimensions. The report includes detailed explanations of physical and mathematical concepts on which the model is based and an explanation of how those concepts are incorporated in the modular structure of the...
Tides, and tidal and residual currents in Suisun and San Pablo bays, California, results of measurements, 1986
J. W. Gartner, B. T. Yost
1988, Water-Resources Investigations Report 88-4027
Current meter data collected at 11 stations and water level data collected at one station in Suisun and San Pablo Bays, California, in 1986 are compiled in this report. Current-meter measurements include current speed and direction, and water temperature and salinity (computed from temperature and conductivity). For each of the...
Tolerances of plants to drought and salinity in the western United States
Farrel Allen Branson, Reuben Fred Miller, Stephen K. Sorenson
1988, Water-Resources Investigations Report 88-4070
Differing capacities of plant species to tolerate drought and salinity are causative factors for presence of species and communities in various habitats. It is proposed that minimum xylem pressure potentials measured are indicative of drought tolerance and that minimum cell osmotic potentials are indicative of salt tolerance of plant species....
Tritium migration from a low-level radioactive-waste disposal site near Chicago, Illinois
J.R. Nicholas, R. W. Healy
1988, Water Supply Paper 2333
This paper describes the results of a study to determine the geologic and hydrologic factors that control migration of tritium from a closed, low-level radioactive-waste disposal site. The disposal site, which operated from 1943 to mid1949, contains waste generated by research activities at the world's first nuclear reactors. Tritium has...
Volatilization of benzene and eight alkyl-substituted benzene compounds from water
R. E. Rathbun, D. Y. Tai
1988, Water Supply Paper 2342
Predicting the fate of organic compounds in streams and rivers often requires knowledge of the volatilization characteristics of the compounds. The reference-substance concept, involving laboratory-determined ratios of the liquid-film coefficients for volatilization of the organic compounds to the liquid-film coefficient for oxygen absorption, is used to predict liquid-film coefficients for...
Preliminary evaluation of ground-water flow in Bear Creek Valley, the Oak Ridge Reservation, Tennessee
Z. C. Bailey
1988, Water-Resources Investigations Report 88-4010
Bear Creek Valley, Tennessee contains hazardous waste disposal sites where contaminants leach into ground and surface water. Groundwater flow and the potential migration of contaminants is poorly understood. The Valley is underlain by calcareous shale that contains limestone units. Ridges to the north and south are underlain by interbedded sandstones,...
A water-resources appraisal of the Mount Shasta area in northern California, 1985
J. C. Blodgett, K.R. Poeschel, J.L. Thornton
1988, Water-Resources Investigations Report 87-4239
Present Mount Shasta, California, area hydrologic characteristics were documented to compare future changes due to land use or volcanic activity. Lower flanks of Mount Shasta consist of broad aprons of pyroclastic-flow, debris flow, and fluvial deposits, with incised channels on upper parts of the mountain. Data include glacial areas and...
Well construction, lithology, and geophysical logs for boreholes in Bear Creek Valley near Oak Ridge, Tennessee
Z. C. Bailey, D. W. Hanchar
1988, Water-Resources Investigations Report 88-4068
Twenty-four wells were constructed at nine sites at Bear Creek Valley to provide geologic and hydrologic information. Lithologic samples and suits of geophysical logs were obtained from the deepest boreholes at six of the sites. Two of these boreholes at the base of Chestnut Ridge were completed in the Maynardville...
Water resources data for Mississippi, water year 1987
E.J. Tharpe, M.L. Plunkett, F. Morris, W. T. Oakley
1988, Water Data Report MS-87-1
Water resources data for the 1987 water year for Mississippi consist of records of stage, discharge, and water quality of streams; stage, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records of water discharge at 78 gaging stations; stage...
Seismicity map of the state of Colorado
C. W. Stover, B.G. Reagor, S. T. Algermissen
1988, Miscellaneous Field Studies Map 2036
This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000.  This map shows only those earthquakes with epicenters located within the boundaries of Colorado, even though earthquakes in...
A computer program incorporating Pitzer's equations for calculation of geochemical reactions in brines
Niel Plummer, D.L. Parkhurst, G.W. Fleming, S.A. Dunkle
1988, Water-Resources Investigations Report 88-4153
The program named PHRQPITZ is a computer code capable of making geochemical calculations in brines and other electrolyte solutions to high concentrations using the Pitzer virial-coefficient approach for activity-coefficient corrections. Reaction-modeling capabilities include calculation of (1) aqueous speciation and mineral-saturation index, (2) mineral solubility, (3) mixing and titration of aqueous...
