Preliminary report on tests of the application of geophysical methods to Arctic ground water problems
David F. Barnes, Gerald R. MacCarthy
1964, Open-File Report 64-9
Seismic refraction and electrical resistivity surveys were made during the summer and fall of 1952 in the Tanana Valley near Fairbanks, Alaska, as part of the studies of the application of geophysical techniques to ground-water problems in Alaska instigated in 1951 by the U.S. Army Engineer Research and Development Laboratories....
Apparatus and techniques for measuring bedload
David Wellington Hubbell
1964, Water Supply Paper 1748
The need for accurate determinations of the total sediment discharge of particles of bedload size has prompted this investigation of available and possible measuring apparatus and procedures. The accuracy of measurements of sediment discharge made with trap-type samplers is affected by the variability of sampler efficiency, by the oscillatory variation...
Sediment transported by Georgia streams
Vance C. Kennedy
1964, Water Supply Paper 1668
A reconnaissance investigation of the sediment transported by selected Georgia streams during the period December 1957 to June 1959 was made to provide a general understanding of the physical quality of stream water in Georgia and to supply facts needed in planning more detailed work. The investigation was made by...
Water levels in observation wells in Santa Barbara County, California, 1963
K. S. Muir
1964, Open-File Report 64-117
The U.S. Geological Survey, in cooperation with the Santa Barbara County Water Agency, continued the study of the ground-water resources of Santa Barbara County (fig. 1) in 1963. As part of the study, the Geological Survey made monthly water-level measurements in 247 wells; 17 of which were equipped with automatic...
Geology and ground-water conditions of the Redwood Falls area, Redwood County, Minnesota
George R. Schiner, Robert Schneider
1964, Water Supply Paper 1669-R
The Redwood Falls area includes about 80 square miles in southwestern Minnesota and is about 100 miles west of Minneapolis and St. Paul. Its surface is a gently undulating glacial-drift plain, interrupted in part by the large Minnesota River valley and the tributary Redwood River valley. The drift plain was...
Floods in Oklahoma: magnitude and frequency
A.O. Westfall, J.L. Patterson
1964, Open-File Report 64-170
This report presents methods by which the magnitude and frequency of expected floods for most streams in Oklahoma can be determined. Flood data were used to define flood-frequency curves applicable to the State. Composite frequency curves were drawn showing the relation of mean annual floods to floods having recurrence intervals...
Discharge characteristics of embankment-shaped weirs
Carl E. Kindsvater
1964, Water Supply Paper 1617-A
An embankment-shaped weir is an embankment overtopped by flood waters. Among the engineering problems frequently resulting from. this occurrence is the need to compute the peak discharge from postflood yield observations. The research described in this. report was concerned with the theoretical and experimental bases for the computation procedure. The...
Inventory of published and unpublished chemical analyses of surface waters in the continental United States and Puerto Rico, 1961
Thomas H. Woodard, Sumner Griggs Heidel
1964, Water Supply Paper 1786
This inventory contains a list of published and unpublished chemical analyses obtained through September 30, 1961, by agencies associated with the Subcommittee on Hydrology. Bulletin 6 of Subcommittee on Hydrology includes references to all surface-water analyses for states east of the Mississippi River known to exist in the files of...
Chemical quality of surface waters in the Brazos River basin in Texas
Burdge Irelan, H.B. Mendieta
1964, Water Supply Paper 1779-K
The Brazos River basin, which makes up 15 percent of the land area of Texas, extends from the High Plains, where altitudes reach 4,200 feet and the average precipitation ranges from 15 to 20 inches a year, to the Gulf of Mexico where the annual rainfall is 45-^50 inches. Large...
Chemical composition of snow in the northern Sierra Nevada and other areas
John Henry Frederick Feth, S. M. Rogers, Charles Elmer Roberson
1964, Water Supply Paper 1535-J
Melting snow provides a large part of the water used throughout the western conterminous United States for agriculture, industry, and domestic supply. It is an active agent in chemical weathering, supplies moisture for forest growth, and sustains fish and wildlife. Despite its importance, virtually nothing has been known of the...
Distribution of mercury, silver, tellurium, arsenic, and antimony in the Rowe Canyon area, White Pine County, Nevada
Garland Bayard Gott, Joseph Howard McCarthy Jr.
1964, Open-File Report 64-63
The accompanying geochemical maps are based in part on data published in U.S. Geological Survey Professional Paper 450-E, Article 180 (Brokaw and others, 1963), and in part on new data acquired since the publication of Professional Paper 450-E. The mercury was determined by atomic absorption techniques, as described by Vaughn...
Ground-water levels in observation wells in Oklahoma, 1961-62
P.R. Wood, M.D. Moeller
1964, Open-File Report 64-169
The investigation of the ground-water resources of Oklahoma by the U. S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water...
Magnitude and frequency of floods in Alaska south of the Yukon River
Vernon Kenneth Berwick, Joseph M. Childers, M.A. Kuentzel
1964, Circular 493
This report presents a method for evaluating the magnitude and frequency of floods on the basis of the analysis of flood records. One composite frequency curve is applied to the entire study region. This curve relates floods of various magnitudes at any site within the region to probable recurrence intervals...
