Data on uranium and radium in ground water in the United States, 1954 to 1957
R. C. Scott, F. B. Barker
1962, Professional Paper 426
This report is one of a series resulting from a study by the U.S. Geological Survey to determine the occurrence and distribution of naturally radioactive substances in water. From 1954-57 uranium and radium concentrations were determined in 561 samples, mainly of ground water, having wide geologic and geographic distribution. These...
Water-supply possibilities at Capitol Reef National Monument, Utah
I. Wendell Marine
1962, Water Supply Paper 1475-G
A water supply of 50 gpm (gallons per minute) is estimated to be sufficient to supply the present and future water demand at the monument. The Coconino sandstone of Permian age seems to be capable of yielding this quantity to a well between 1,500 and 2,700 feet deep in the...
Methods of measuring soil moisture in the field
A.I. Johnson
1962, Water Supply Paper 1619-U
For centuries, the amount of moisture in the soil has been of interest in agriculture. The subject of soil moisture is also of great importance to the hydrologist, forester, and soils engineer. Much equipment and many methods have been developed to measure soil moisture under field conditions. This report discusses...
A national network of hydrological benchmarks
Luna Bergere Leopold
1962, Circular 460-B
We are engaged in great national programs of water control and development. An expanding population demands ever-increasing supplies of the natural resources which are to be found in or upon the landscape soil, water, minerals, food, timber, and fiber. By his works, by his extractions, man's mark upon his environment...
Theory of aquifer tests
J.G. Ferris, D.B. Knowles, R. H. Brown, R.H. Stallman
1962, Water Supply Paper 1536-E
The development of water supplies from wells was placed on a rational basis with Darcy's development of the law governing the movement of fluids through sands and with Dupuit's application of that law to the problem of radial flow toward a pumped well. As field experience increased, confidence in the...
Ground-Water Reconnaissance at Pinnacles National Monument, California
R. E. Evenson
1962, Water Supply Paper 1475-K
Ground-water supplies at Pinnacles National Monument have been obtained from springs that occur in fractures and along bedding planes of volcanic flows and deposits, and from springs discharged from perched water in a sedimentary fanglomerate formation. The spring-water yield is barely adequate to supply existing camp facilities, and therefore a...
Ground-water studies and analog models
Charles Joseph Robinove
1962, Circular 468
Hydrologists make ground-water studies to aid managers and users of water resources in solving their problems in the development and management of ground water. Geologic and hydrologic information provides the basic knowledge for construction of electric analog models that portray the ground-water system in miniature. Analog models can be analyzed...
Notes on earth fissures in southern Arizona
G.M. Robinson, D.E. Peterson
1962, Circular 466
This report describes earth fissures at six sites in southern Arizona. These notes are preliminary to a more extensive study and detailed analysis being prepared by hydrologists in the Water Resources Division. Earth fissures were first recorded in Arizona in 1927, and have been noticed with increasing frequency since 1949....
Reconnaissance of ground-water resources in the Eastern Coal Field Region, Kentucky
William E. Price, D. S. Mull, Chabot Kilburn
1962, Water Supply Paper 1607
In the Eastern Coal Field region of Kentucky, water is obtained from consolidated sedimentary rocks ranging in age from Devonian to Pennsylvanian and from unconsolidated sediments of Quaternary age. About 95 percent of the area is underlain by shale, sandstone, and coal of Pennsylvanian age. Principal factors governing the availability...
Current studies of the hydrology of prairie potholes
Jelmer B. Shjeflo
1962, Circular 472
The prairie potholes in the North-Central States and in Canada are of glacial origin. Because many of them contain ponds or marshes, they are important in the production of livestock and waterfowl. The objective of the present investigation is to determine the amount of water that accumulates in and is...
An application of thermometry to the study of ground water
Robert Schneider
1962, Water Supply Paper 1544-B
Except for studies of temperature data related to ground-water developments that induce infiltration from streams, little attention has been given to the possibility of using temperature fluctuations as a tool for studying the elements of the hydrologic cycle involving ground water. The temperature of the water discharged from large installations that...
Floods in Utah, magnitude and frequency
Vernon K. Berwick
1962, Circular 457
This report presents a procedure for estimating the magnitude and frequency of floods, within the range of the base data, for any site, gaged or ungaged. From the relation of annual floods to the mean annual flood, a composite frequency curve was derived for recurrence intervals of 1.1 to 50...
Floods in Nebraska on small drainage areas, magnitude and frequency
Emil W. Beckman, Norman E. Hutchison
1962, Circular 458
Flood hazard information is needed for small streams as well as for large ones. This report explains methods of defining the magnitude and frequency of floods in Nebraska on uncontrolled and unregulated streams which have about 300 square miles or less of drainage area contributing to surface runoff. Composite frequency...
Controlled induced recharge tests at Kalamazoo, Mich
Morris Deutsch
1962, Journal - American Water Works Association (54) 181-196
This article discusses the results of a controlled field testing program, which indicated that definite hydraulic and other advantages may be gained from induced recharging as practiced at Kalamazoo, Michigan. Results include the following: water levels and artesian pressures can be maintained at high stages, the results are lower pumping...
Statistical properties of tree ring data
N.C. Matalas
1962, International Association of Scientific Hydrology - Bulletin (7) 39-47
A statistical analysis is made of the sequences of annual tree ring widths and indices. The expected value of growth during any year is shown to be proportional to the standard deviation of the growth, so that the coefficient of variation is a measure of the sensitivity of the growth of a <span...
The distribution of tritium fallout in precipitation over North America
L. L. Thatcher
1962, International Association of Scientific Hydrology - Bulletin (7) 48-58
In 1958 the U.S. Geological Survey and the U.S. Weather Bureau jointly conducted a study of tritium fallout distribution over the continental United States, Alaska, and Puerto Rico. The observation period extended from early April to late July in most areas. While this was insufficient to cover the decay side of the...
Progress report on an international decade for hydrology
W. B. Langbein
1962, Article
As reported in the Transactions of March 1961 (p. 96), the ad hoc Panel on Hydrology convened to report on ways of stimulating research in scientific hydrology, recommended a program of international cooperation in hydrology—more specifically a plan for an ‘International Decade for Hydrology,’ as drawn for the Panel by R. L. Nace....
