Occurrence of strontium in natural water
M. W. Skougstad, C. Albert Horr
1960, Circular 420
The regions where the stable strontium content of surface waters is relatively low (less than 0.50 ppm) include the Pacific Northwest, Northeastern United States, and the Central Lowlands, Particularly the Lower Mississippi basin and the Western Gulf Coast area. Moderate concentrations of strontium (0.50 to 1.5 ppm) are found in...
Time, distance, and drawdown relationships in a pumped ground-water basin
Fred Kunkel
1960, Circular 433
Several reasonable values are assumed for coefficients of transmissibility and storage of lenticular alluvial deposits, These values when substituted in the Theis (1935) nonequilibrium formula as modified by Wenzel (1942) give curves from which time, distance, drawdown relationships are estimated....
Wetland and water supply
John Augustus Baker
1960, Circular 431
The Geological Survey has received numerous inquiries about the effects of proposed changes in the wetland environment. The nature of the inquiries suggests a general confusion in the public mind as to wetland values and an increasing concern by the public with the need for facts as a basis for...
A field instrument for quantitative determination of beryllium by activation analysis
William W. Vaughn, E.E. Wilson, J.M. Ohm
1960, Circular 427
A low-cost instrument has been developed for quantitative determinations of beryllium in the field by activation analysis. The instrument makes use of the gamma-neutron reaction between gammas emitted by an artificially radioactive source (Sb124) and beryllium as it occurs in nature. The instrument and power source are mounted in a...
Progress report on use of water by riparian vegetation, Cottonwood Wash, Arizona
E. L. Hendricks, William Kam, James E. Bowie
1960, Circular 434
Measurements of streamflow, ground-water levels, and meterological data obtained in a 4.1-mile reach of the flood plain of Cottonwood Wash, Mohave County, Ariz., define the use of water by riparian vegetation in that part of the stream valley. The computed evapotranspiration loss during the growing season of 1959 was 175...
Availability of ground water at the border stations at Laurier and Ferry, Washington
Kenneth Lyle Walters
1960, Circular 422
In the Laurier area, Washington, the Kettle River has cut into crystalline rocks in the deepest part of the valley. Sand and gravel fill were deposited in the valley during Pleistocene time by melt water from glaciers, and subsequent erosion and alluviation formed three terrace levels. The highest level, on...
Ecological systems and the water resources
Luna Bergere Leopold
1960, Circular 414-D
In ancient Sparta there were two principal classes of society, the citizen and the helot. The citizen was trained principally to be a warrior. The helot, a serf, was the tiller of the land but could be called to military duty. The history of Herodotus makes it amply clear that...
Conservation and protection
Luna Bergere Leopold
1960, Circular 414-A
When I was a child we had a burro I called Gacho. He was a typical burro, omnivorous in his eating habits and prone to streaks of extreme recalcitrance.Our yard wasn't very large, but it did produce enough grass and weeds to keep old Gacho in good fettle. His first...
The conservation attitude
Luna Bergere Leopold
1960, Circular 414-C
Forsaking his inheritance and its assurance of a comfortable existence, Guatama Buddha adopted the life of a pauper to seek the intellectual joys of pure contemplation. Under a mulberry tree, it is said, he propounded a 12-point program of ethical conduct stressing the development of a disinterested outlook in each...
Graphical correlation of gaging-station records
James K. Searcy
1960, Water Supply Paper 1541-C
A gaging-station record is a sample of the rate of flow of a stream at a given site. This sample can be used to estimate the magnitude and distribution of future flows if the record is long enough to be representative of the long-term flow of the stream. The reliability...
