The ground-water system in southeastern Laramie County, Wyoming
Marvin A. Crist, William B. Borchert
1972, Open-File Report 72-80
Increased development of irrigation wells in southeastern Laramie County, Wyo., has caused concern about the quantity of water available. Ground water from approximately 230 large-capacity wells is used to irrigate most of the 18,165 acres under irrigation. The purpose of this study is to provide more knowledge about the character...
An inventory of published and unpublished fluvial-sediment data for California, 1956-70
George Porterfield
1972, Open-File Report 72-300
This inventory was prepared to provide a convenient reference to published and unpublished fluvial-sediment data for water years 1956-70, and updates substantially previous inventories. Sediment stations are listed in downstream order, and an alphabetical list of stations is also included. Figure 1 shows the approximate location of sediment stations in...
Reconnaissance geology of the Precambrian rocks in the Ayn Qunay quadrangle, Kingdom of Saudi Arabia
William C. Overstreet, Jesse William Whitlow, Abdullah O. Ankary
1972, Open-File Report 72-281
The Aya Qunay quadrangle covers an area of 2833 sq km in central Saudi Arabia, Only the western edge of the quadrangle is underlain by Precambrian rocks, which were the subject of this investigation. Toward the east the Precambrian rocks are unconformably overlain by Permian and younger sedimentary rocks. The...
Artificial recharge in the upper Santa Ana Valley, southern California
Joe A. Moreland
1972, Open-File Report 72-261
Artificial recharge has long been an integral part of water-supply management in the upper Santa Ana Valley. About 7,500 acres of unlined channels and 2,590 acres in 60 off-channel recharge facilities are available for water spreading.To estimate potential infiltration rates for the recharge facilities, 63 single-ring infiltrometer tests were conducted...
Tectonic map of Liberia based on geophysical and geological surveys
John Charles Behrendt, Cletus S. Wotorson
1972, Open-File Report 72-32
Interpretation of the results of aeromagnetic, total-gamma radioactivity, and gravity surveys combined with geologic data for Western Liberia from White and Leo (1969) and other geologic information allows the construction of a tectonic map of Liberia. The map approximately delineates the boundaries between the Liberian (ca. 2700 m.y.) province in...
Reconnaissance geology of the Jabal Bitran quadrangle, Kingdom of Saudi Arabia
Viktor P. Kahr, W.C. Overstreet, J. W. Whitlow, A.O. Ankary
1972, Open-File Report 72-204
The Jabal Bitten quadrangle covers an area of 2833 sq km in the eastern part of the Precambrian Shield in Saudi Arabia. The rocks in the quadrangle are divided geographically alone arcuate north-trending lines into an eastern area of granite intruded by a swarm of dikes of rhyolite and andesite,...
Hydrologic interpretations based on infrared imagery of Long Island, New York
Edward J. Pluhowski
1972, Water Supply Paper 2009-B
Six remote-sensing flights over Long Island's north and south shores were made during the period July 13, 1967, to February 25, 1970. Infrared imagery in the 8- to 14-micrometer range was obtained; results varied from poor to excellent in quality. The ability of the RS 7 and Reconofax IV imagers...
Effect of aging on aluminum hydroxide complexes in dilute aqueous solutions
Ross Wilbert Smith, John David Hem
1972, Water Supply Paper 1827-D
Aqueous aluminum solutions containing 4?10 -5 mole/liter aluminum and a constant total ionic strength of 10 -2, but with varying ratios of hydroxide to aluminum (OH:Al), were prepared. Progress of these solutions toward equilibrium conditions over aging periods of as much as 2 years was studied by determining the composition...
