A method of estimating flood-frequency parameters for streams in Idaho
L.C. Kjelstrom, R. L. Moffatt
1981, Open-File Report 81-909
Skew coefficients for the log-Pearson type III distribution are generalized on the basis of some similarity of floods in the Snake River basin and other parts of Idaho. Generalized skew coefficients aid in shaping flood-frequency curves because skew coefficients computed from gaging stations having relatively short periods of peak flow...
Bed form distribution and inferred sand transport on Georges Bank
David C. Twichell
1981, Open-File Report 81-764
Four bed-form provinces have been identified on Georges Bank using sidescan sonar and echo-sounding techniques: large sand waves, small sand waves, megaripples, and featureless sea floor. The large sand waves are found on the bank crest where the surface tidal currents are strongest, and are bordered, north and south, by...
Luminescence images of the Patrick Draw geosat petroleum test site, Wyoming
Robert Watson
1981, Open-File Report 81-606
In collaboration with the Geosat committee remote sensing test site program, luminescence images were acquired of parts of the Patrick Draw-Brady oil and gas test site in Wyoming. The Fraunhofer line discriminator was operated at 486.1 nanometer, 589.0 nanometer, and 656.3 nanometer Fraunhofer lines. Most of the luminescence highs occur...
Water-quality data for selected stations in the East Everglades, Florida
Bradley G. Waller
1981, Open-File Report 81-821
The results of water-quality samples collected from April 1978 through April 1980 from three canal stations, four marsh stations, and two ground-water stations within the East Everglades, Dade County, Florida, are tabulated in 37 tables. The major categories of parameters analyzed are field measurements, physical characteristics, macronutrients (carbon, nitrogen, and...
Floodflow characteristics related to channel geometry in Ohio
E.E. Webber, J.W. Roberts
1981, Open-File Report 81-1105
Techniques for estimating magnitude and frequency of flood-peak discharges, based on channel geometry parameters, are presented as a method for evaluating Ohio floods in geographic areas deficient in flow data. One hundred and sixty gaging stations were selected on streams with alluvial channels unaltered by man. Exposed bedrock is absent...
Annotated bibliography of remote sensing methods for monitoring desertification
A. S. Walker, Charles J. Robinove
1981, Circular 851
Remote sensing techniques are valuable for locating, assessing, and monitoring desertification. Remotely sensed data provide a permanent record of the condition of the land in a format that allows changes in land features and condition to be measured. The annotated bibliography of 118 items discusses remote sensing methods that may...
Chemical character of ground water in the shallow water-table aquifer at selected localities in the Memphis area, Tennessee
William Scott Parks, D. D. Graham, J.F. Lowery
1981, Open-File Report 81-223
Eight deep wells are being monitored in the Memphis, Tenn., area to detect any changes in the chemical character of water moving through the Memphis Sand towards major pumping centers. These wells are strategically located so as to intercept groundwater enroute through the Memphis Sand from the outcrop-recharge area. Although...
Publication search and retrieval system
Elizabeth A. Winget
1981, Open-File Report 81-1096
The publication search and retrieval system of the Branch of Atlantic-Gulf of Mexico Geology, U.S. Geological Survey, Woods Hole, Mass., is a procedure for listing and describing branch-sponsored publications. It is designed for maintenance and retrieval by those having limited knowledge of computer languages and programs. Because this branch currently...
