Reservoirs in the United States
G. Earl Harbeck Jr.
1948, Circular 23
Man has engaged in the control of flowing water since history began. Among his early recorded efforts were reservoirs for muncipal water-supplies constructed near ancient Jerusalem to store water which was brought there in masonry conduits. 1/  Irrigation was practiced in Egypt as early as 2000 B. C. There the...
Flood of September 1946 at San Antonio, Texas
Seth D. Breeding
1948, Circular 32
A flood occurred in the streams in and near San Antonio, Teat., during the early morning hours of September 27, 1946, as a result of heavy rains falling during the previous night. Much property damage occurred in San Antonio and below, and four lives were lost. . It is the...
Discharge and runoff in the Missouri River basin
Bruce R. Colby, Roy E. Oltman
1948, Circular 37
Within the Missouri River Basin the precipitation and temperature vary greatly with both time and geographical location. Differences in weather and climate combine with differences in topography and geology to produce large differences in runoff from time to time and from place to place in the basin. The average annual...
Floods in Colorado
Robert Follansbee, Leon R. Sawyer
1948, Water Supply Paper 997
The first records of floods in Colorado antedated the settlement of the State by about 30 years. These were records of floods on the Arkansas and Republican Rivers in 1826. Other floods noted by traders, hunters and emigrants, some of whom were on their way to the Far West, occurred...
Index of surface-water records, part 3, Ohio River basin, to September 30, 1948
Water Resources Division, U.S. Geological Survey
1948, Circular 39
This report summarizes ground-water-quality data, for Wisconsin, stored in the U.S. Geological Survey 's computer system (WATSTORE). The summary includes water-quality data for 2,443 wells which tap one of the State 's three major aquifers (sand and gravel, Silurian dolomite, and sandstone). Data for dissolved solids, hardness, alkalinity, calcium, magnesium,...
Some solutional features of the limestone near Lexington, Kentucky
D.K. Hamilton
1948, Economic Geology (43) 39-52
Field work on the Ordovician limestones and shales of the Lexington area, Kentucky, has shown that no appreciable quantity of ground water is transmitted through interstitial openings in these rocks. Ground-water movement is restricted to joint planes and, to a lesser extent, bedding planes that have been enlarged by solution....
Quality of water in the upper Colorado River basin
C. S. Howard
1948, Eos, Transactions, American Geophysical Union (29) 375-378
In a drainage area as large as the Colorado River Basin there are naturally large differences in the quality of the surface waters. The chemical character of the water at six gaging stations on the Colorado River from near the headwaters to near the mouth is shown by the analyses...
Fluctuations in concentration of dissolved solids of some southwestern streams
J.D. Hem
1948, Eos, Transactions, American Geophysical Union (29) 80-84
The concentration of dissolved solids in waters of streams of the Southwestern United Stated fluctuates widely as the stream discharge changes. These fluctuations may be extensive in a period of a few days or even a few hours. Data in this paper show the extent of the day‐to‐day changes in...
Geology and ground-water resources of Iwo Jima 
F. A. Swenson
1948, GSA Bulletin (59) 995-1008
Iwo Jima, in the western Pacific Ocean, consists of Motoyama, a broad volcanic cone, at the north, and Mt. Suribachi at the south, with an undulating isthmus between. Motoyama is largely light-gray-buff tuff. A thick andesitic lava flow under Suribachi, exposed in several places, is overlain by a thick deposit...
Report of Committee on Ground Water, 1945–1946
S. W. Lohman
1948, Eos, Transactions, American Geophysical Union (29) 117-123
The principal activity of the Committee during the year was the arranging and presentation of a symposium on methods of estimating ground‐water supplies. The response was gratifying and resulted in the presentation of 11 interesting papers at the 1946 meeting. The report of the Subcommittee on Permeability by C. E....
Development of limestone reservoirs in Comal County, Texas
W.O. George
1948, Eos, Transactions, American Geophysical Union (29) 503-510
The Edwards limestone, and to a lesser extent the Comanche Peak limestone and the lower part of the Glen Rose limestone below, all of Lower Cretaceous age, form one of the most extensive ground‐water reservoirs in Texas. As a result of normal faulting, these formations are connected by underground channels...
Hydrology of limestone terrane in Schoharie County, New York
Jean Milton Berdan
1948, Eos, Transactions, American Geophysical Union (29) 251-253
During the summer of 1946 the writer studied the ground‐water resources of Schoharie County, New York, as a part of the program of ground‐water investigation being carried on in cooperation between the United States Geological Survey and the New York State Water Power and Control Commission. Because the outcrop belt...
Runoff from rain and snow
A. M. Piper
1948, Eos, Transactions, American Geophysical Union (29) 511-524
The basic principles of the idealized hydrologic cycle are reviewed with emphasis on storage and movement of water in the soil. A distinction is made between ground‐water runoff and overland runoff in terms of storage and lag, expressed as accumulated deviations from uniform flow over a period of several years....
Trends in runoff in the Pacific Northwest
C. C. McDonald, W. B. Langbein
1948, Eos, Transactions, American Geophysical Union (29) 387-397
The diminution in runoff in the Pacific Northwest, particularly the Columbia River Basin, during the past 50 years, and its hydrologic significance are discussed in this paper. An analysis of the rainfall‐runoff relations for the Basin is made in order to explain the different influence of short‐ and long‐term precipitation...
Quality of water in the northwest
C. S. Howard
1948, Eos, Transactions, American Geophysical Union (29) 379-383
AbstractThe quality of natural waters, as judged by the dissolved mineral content, is quite varied throughout the Northwest. The concentrations of dissolved solids range from less than 50 ppm for many of the surface waters in Washington and Oregon, to several thousand ppm in...
Effect of water temperature on flow of a natural stream
William Stewart Eisenlohr Jr.
1948, Eos, Transactions, American Geophysical Union (29) 240-242
Approximately three per cent of the variation in streamflow of the Kootenai River near Copeland, Idaho, has been found to be associated with variation in water temperature. This has been determined by correlation analysis of residuals in streamflow that were not accounted for by either gage height or slope....
A sensitive field test for heavy metals in water
Lyman C. Huff
1948, Economic Geology (43) 675-684
A semiquantitative colorimetric analytical method using dithizone to detect traces of heavy metals in natural water is described. Although reagents of exceptional purity are required, only simple equipment is needed and the test can be made in a few minutes in the field. A combined mixed color and mono color...
Geology and ground water of the Casablanca Basin, Chile
G. C. Taylor Jr.
1948, Economic Geology (73) 661-674
"In the uplands the Cretaceous granodiorite and granite contain water in the weathered zones, and in joints and fractures. These yield small supplies of good water to springs and to shallow domestic and stock wells. The alluvial fill of the lowlands contains a zone of saturation that is sustained by...
