Water resources data, Missouri, water year 1983
L.A. Waite, D.O. Hatten, P. W. Cross
1984, Water Data Report MO-83-1
Water resources data for the 1983 water year for Missouri consist of records of stage, discharge, and water quality of lakes and reservoirs; contains records for water discharge at 110 gaging stations; stage and contents at 9 lakes and reservoirs; water quality at 24 gaging stations (including 1 lake) and...
Bathymetric map of Lydonia Canyon, U.S. Atlantic Outer Continental Shelf
Bradford Butman, John A. Moody
1984, Miscellaneous Field Studies Map 1710
Lydonia Canyon is one of several large submarine canyons that indent the eastern U.S. Continental Shelf along the southern flank of Georges Bank (Index map).  This bathymetric map of the upper part of Lydonia Canyon (water depths shallower than about 2,00 m) was prepared as part of a study of...
Seismicity map of the state of Colorado
C. W. Stover, B.G. Reagor, S. T. Algermissen
1984, Miscellaneous Field Studies Map 1694
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969). This data file has been recompiled and updated through 1981. Some revisions of epicenters and intensities in the original file...
The effect of eustatic sea-level changes on saltwater-freshwater relations in the northern Atlantic Coastal Plain
Harold Meisler, P. Patrick Leahy, LeRoy L. Knobel
1984, Water Supply Paper 2255
A finite-difference computer model was used to analyze the effect of eustatic sea-level changes on the development of the transition zone between fresh ground water and underlying saltwater in the northern Atlantic Coastal Plain. The model simulates, in cross section, the sedimentary wedge from the Delaware River estuary in New...
Appraisal of data for ground-water quality in Nebraska
R. A. Engberg
1984, Water Supply Paper 2245
This report summarizes existing data for groundwater quality in Nebraska and indicates their adequacy as a data base. Analyses have been made of water from nearly 10,000 wells by 8 agencies. Those analyses that meet reliability criteria have been aggregated by geologic source of water into four principal aquifer groupings--Holocene-Pleistocene...
Interpolating water-table altitudes in west-central Kansas using kriging techniques
L. E. Dunlap, Joseph M. Spinazola
1984, Water Supply Paper 2238
Kriging is a regionalization technique that incorporates the autocorrelation between known data values in its estimation of values at unmeasured sites. This technique is reproducible, accepts irregularly spaced data, uses only measured values closely surrounding points at which values are estimated, is an exact interpolator at measured data points, and...
Hydrologic characteristics of Nebraska soils
Jack T. Dugan
1984, Water Supply Paper 2222
The influence of the physical characteristics of soil on hydrology is frequently neglected. In this report, the effects of five characteristics on the hydrologic responses of soils in Nebraska are evaluated quantitatively, soils are grouped through use of a simplified coding system according to similarities in hydrologic responses, and are...
Rainfall-runoff data in the Albuquerque, New Mexico, metropolitan area, 1976-83
E.E. Fischer, J.J. Rote, J.B. Borland
1984, Open-File Report 84-448
Rainfall and discharge data from 13 flood-hydrograph stations in the Albuquerque, New Mexico, metropolitan area are presented. The period of record is from 1976, when the first three stations were installed, through 1983. The data include daily mean values for discharge for the period of record at each station, monthly...
Water-level hydrographs for observation wells in Virginia, 1982
Stephen Farrington, Natalie Carrington, W.V. Daniels Jr.
1984, Open-File Report 84-134
Water-well data for 1982 are presented from 147 observation wells in Virginia. Historical data from two wells are also included. A description of each observation well is provided that gives the well location, site identification number, hydrologic unit, owner, aquifer, well characteristics, general remarks, period of record, and extreme measurements...
Cost effectiveness of the stream-gaging program in Maine; A prototype for nationwide implementation
Richard A. Fontaine, M. E. Moss, J.A. Smath, W. O. Thomas
1984, Water Supply Paper 2244
This report documents the results of a cost-effectiveness study of the stream-gaging program in Maine. Data uses and funding sources were identified for the 51 continuous stream gages currently being operated in Maine with a budget of \$211,000. Three stream gages were identified as producing data no longer sufficiently needed...
Geohydrologic data for test well UE-25p1, Yucca Mountain area, Nye County, Nevada
R. W. Craig, K. A. Johnson
1984, Open-File Report 84-450
This report presents the following data for test well UE-25p 1 in Nye County, Nevada: drilling operations, lithology, availability of borehole geophysical logs, water levels, future availability of core analyses, water chemistry, pumping tests, borehole-flow surveys, and packer-injection tests. The well is one of a series of test wells drilled...
Geophysical interpretation of the gneiss terrane of northern Washington and southern British Columbia, and its implications for uranium exploration
John W. Cady, Kenneth F. Fox
1984, Professional Paper 1260
The Omineca crystalline belt of northeastern Washington and southern British Columbia has a regional Bouguer gravity high, and individual gneiss domes within the terrane are marked by local gravity highs. Models of crustal structure that satisfy the limited available seismic-refraction data and explain the gravity high over the gneiss terrane...
Annual water-resources review, White Sands Missile Range, New Mexico, 1983
R. R. Cruz
1984, Open-File Report 84-720
Ground-water data were collected at White Sands Missile Range in 1983. The total amount of water pumped from White Sands Missile Range supply wells in 1983 was 713,557,500 gallons. The Post Headquarters well field accounted for 686,499,200 gallons of the total. Seasonal water-level fluctuations in the supply wells ranged from...
Interpretation of core and well log physical property data from drill hole UPH-3, Stephenson County, Illinois
J.J. Daniels, G.R. Olhoeft, J. H. Scott
1984, Open-File Report 82-941
Laboratory and well log physical property measurements show variations in the mineralogy with depth in UPH-3. Gamma ray values generally decrease with depth in the drill hole, corresponding to a decrease in the felsic mineral components of the granite. Correspondingly, an increase with depth in mafic minerals in the granite...
Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980
S.D. Goodwin, B.I. Schultz, D.L. Parkhurst, N.S. Simon, Edward Callender
1984, Open-File Report 84-74
The chemical composition of bottom sediments and their associated pore waters from the tidal Potomac River and Estuary was studied from May 1978 through June 1980. Pore waters were routinely analyzed for pH, Eh, alkalinity, and concentrations of sulfide, sulfate, phosphate, carbon, ammonium, silica, iron, manganese, chloride, sodium, potassium, calcium,...
