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...
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...
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...
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...
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...
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...
Floods at Mount Clemens, Michigan
S.W. Wiitala, Arlington D. Ash
1962, Hydrologic Atlas 59
The approximate areas inundated during the flood of April 5-6, 1947, by Clinton River, North Branch and Middle Branch of Clinton River, and Harrington Drain, in Clinton Township, Macomb County, Mich., are shown on a topographic map base to record the flood hazard in graphical form. The flood of April...
Portrayal of drainage and vegetation on topographic maps
W.J. Schneider, J. C. Goodlett
1962, Open-File Report 62-121
Accurate measurements of drainage networks are necessary for studies in many scientific disciplines, especially hydrology. To this end, topographic maps must show accurate classification as well as a consistent pattern of the stream network.A recent study in Georgia has developed two photo-interpretive keys which permit accurate drainage classification during the...
The concept of entropy in landscape evolution
Luna Bergere Leopold, Walter Basil Langbein
1962, Professional Paper 500-A
The concept of entropy is expressed in terms of probability of various states. Entropy treats of the distribution of energy. The principle is introduced that the most probable condition exists when energy in a river system is as uniformly distributed as may be permitted by physical constraints. From these general...
