USGS research on energy resources, 1986; program and abstracts
Lorna M.H. Carter, editor(s)
1986, Circular 974
The extended abstracts in this volume are summaries of the papers presented orally and as posters in the second V. E. McKelvey Forum on Mineral and Energy Resources, entitled "USGS Research on Energy Resources-1986." The Forum has been established to improve communication between the USGS and the earth science community...
Evaluation of six methods for estimating magnitude and frequency of peak discharges on urban streams in New York
D.A. Stedfast
1986, Water-Resources Investigations Report 84-4350
Six methods of estimating peak discharges of urban streams were compared and evaluated for applicability to urban streams in New York. Discharge and frequency values developed from a series of synthesized annual flood records were compared with values obtained from the six methods. The synthesized flood records were computed from...
Computer programs for computing particle-size statistics of fluvial sediments
H.H. Stevens, D. W. Hubbell
1986, Water-Resources Investigations Report 86-4141
Two versions of computer programs for inputing data and computing particle-size statistics of fluvial sediments are presented. The FORTRAN 77 language versions are for use on the Prime computer, and the BASIC language versions are for use on microcomputers. The size-statistics program compute Inman, Trask , and Folk statistical parameters...
Analytical results and sample locality map of heavy-mineral-concentrate and rock samples from the Castle Peaks Wilderness Study Area (CDCA- 266), San Bernardino County, California
B. M. Adrian, J. G. Frisken, M.J. Malcolm, J.G. Crock
1986, Open-File Report 86-416
The report presents water-quality and geohydrologic information for 106 public water-supply wells in Illinois. These wells were sampled during April to December 1984 as part of a pilot program to develop a ground-water observation network in the State. The pilot program was designed to sample single-aquifer wells from three major...
Cost-effectiveness of the U.S. Geological Survey stream-gaging program in Indiana
J. A. Stewart, R. L. Miller, G.K. Butch
1986, Water-Resources Investigations Report 85-4343
Analysis of the stream gaging program in Indiana was divided into three phases. The first phase involved collecting information concerning the data need and the funding source for each of the 173 surface water stations in Indiana. The second phase used alternate methods to produce streamflow records at selected sites....
Aquifer-nomenclature guidelines
R. L. Laney, C.B. Davidson
1986, Open-File Report 86-534
Guidelines and recommendations for naming aquifers are presented to assist authors of geohydrological reports in the United States Geological Survey, Water Resources Division. The hierarchy of terms that is used for water- yielding rocks from largest to smallest is aquifer system, aquifer, and zone. If aquifers are named, the names...
Method for estimating low-flow characteristics of ungaged streams in Indiana
Leslie D. Arihood, Dale R. Glatfelter
1986, Open-File Report 86-323
Equations for estimating the 7-day, 2-year and 7-day, 10-year low flows at sites on ungaged streams are presented. Regression analysis was used to develop equations relating basin characteristics and low-flow characteristics at 82 gaging stations. Significant basin characteristics in the equations are contributing drainage area and flow-duration ratio, which is...
Evaluation of coal-mining impacts using numerical classification of benthic invertebrate data from streams draining a heavily mined basin in eastern Tennessee
A.D. Bradfield
1986, Water-Resources Investigations Report 85-4289
Coal-mining impacts on Smoky Creek, eastern Tennessee were evaluated using water quality and benthic invertebrate data. Data from mined sites were also compared with water quality and invertebrate fauna found at Crabapple Branch, an undisturbed stream in a nearby basin. Although differences in water quality constituent concentrations and physical habitat...
Effect of bank protection measures, Stehekin River, Chelan County, Washington
L. M. Nelson
1986, Water-Resources Investigations Report 85-4316
An investigation of the lower Stehekin River was conducted to study the effects on flood elevations and velocities from four bank protection and flood prevention measures that are being contemplated as a means of reducing erosional losses of river bank property. These measures are: bank armoring, armored revetment levees, spur...
