Ground-water conditions and geologic reconnaissance of the Upper Sevier River basin, Utah
Carl H. Carpenter, Gerald B. Robinson, Louis Jay Bjorklund
1967, Water Supply Paper 1836
The upper Sevier River basin is in south-central Utah and includes an area of about 2,400 .square miles of high plateaus and valleys. It comprises the entire Sevier River drainage basin above Kingston, including the East Fork Sevier River and its tributaries. The basin was investigated to determine general ground-water...
A comparison of methods of estimating potential evapotranspiration from climatological data in arid and subhumid environments
R.W. Cruff, T. H. Thompson
1967, Water Supply Paper 1839-M
This study compared potential evapotranspiration, computed from climatological data by each of six empirical methods, with pan evaporation adjusted to equivalent lake evaporation by regional coefficients. The six methods tested were the Thornthwaite, U.S. Weather Bureau (a modification of the Permian method), Lowry-Johnson, Blaney-Criddle, Lane, and Hamon methods. The test...
Geology and hydrology between Lake McMillan and Carlsbad Springs, Eddy County, New Mexico
Edward Riley Cox
1967, Water Supply Paper 1828
The hydrology of the Pecos River valley between Lake McMillan and Carlsbad Springs, Eddy County, N. Mex., is influenced by facies changes in rocks of Permian age. Water stored for irrigation leaks from Lake McMillan into evaporite rocks, principally gypsum, of the Seven Rivers Formation and from Lake Avalon into...
Swatara Creek basin of southeastern Pennsylvania: An evaluation of its hydrologic system
Wilbur Tennant Stuart, William J. Schneider, James W. Crooks
1967, Water Supply Paper 1829
Local concentrations of population in the Swatara Creek basin of Pennsylvania find it necessary to store, transport, and treat water because local supplies are either deficient or have been contaminated by disposal of wastes in upstream areas. Water in the basin is available for the deficient areas and for dilution...
Water requirements of the iron and steel industry
Faulkner B. Walling, Louis Ethelbert Otts Jr.
1967, Water Supply Paper 1330-H
Twenty-nine steel plants surveyed during 1957 and 1958 withdrew from various sources about 1,400 billion gallons of water annually and produced 40.8 million tons of ingot steel. This is equivalent to about 34,000 gallons of water per ton of steel. Fifteen iron ore mines and fifteen ore concentration plants together...
Marine sediment sample preparation for analysis for low concentrations of fine detrital gold
H. Edward Clifton, Arthur Hubert, R. Lawrence Phillips
1967, Circular 545
Analyses by atomic absorption for detrital gold in more than 2,000 beach, offshore, marine-terrace, and alluvial sands from southern Oregon have shown that the values determined from raw or unconcentrated sediment containing small amounts of gold are neither reproducible nor representative of the initial sample. This difficulty results from a...
Economic significance of revised age relations of rocks in the Cornucopia mining district, Elko County, Nevada
Robert Roy Coats
1967, Circular 549
Recent geologic work in the Cornucopia mining district, a small silver-gold mining district in northwestern Elko County, Nev., has resulted in significant revision of the geological interpretation. Rocks formerly thought to be premineralization in age, but unmineralized, are now known to be postmineral extrusives, resting unconformably on the altered andesite...
Measurement of peak discharge at width contractions by indirect methods
Howard Frederick Matthai
1967, Techniques of Water-Resources Investigations 03-A4
This chapter describes procedures for measuring peak discharges using open-channel width contractions. Field and office procedures limited to this method are described. The discharge equation based on the continuity and energy equations between an approach cross section and the contracted section under a bridge or contraction is given. Contractions...
Determination of gold in geologic materials by solvent extraction and atomic-absorption spectrometry
Claude Huffman, J.D. Mensik, L.B. Riley
1967, Circular 544
The two methods presented for the determination of traces of gold in geologic materials are the cyanide atomic-absorption method and the fire-assay atomic-absorption method. In the cyanide method gold is leached with a sodium-cyanide solution. The monovalent gold is then oxidized to the trivalent state and concentrated by extracting into...
Effects of the Truckee, California, earthquake of September 12, 1966
Reuben Kachadoorian, R. F. Yerkes, Arvi O. Waananen
1967, Circular 537
The Truckee, Calif., earthquake of September 12, 1966, had a magnitude of 5.4 on the Richter scale, as reported by the U.S. Coast and Geodetic Survey. It was felt over an area extending from San Francisco eastward to Salt Lake City and from Bakersfield northward beyond Chico, Calif. Ground breakage...
