Bedrock geology of the Mount Carmel and Southington quadrangles, Connecticut
Crawford Ellswroth Fritts
1962, Open-File Report 62-48
New data concerning the geologic structure, stratigraphy, petrography, origin, and ages of bedrock formations in an area of approximately 111 square miles in south-central Connecticut were obtained in the course of detailed geologic mapping from 1957 to 1960. Mapping was done at a scale of 1:24,000 on topographic base maps...
Geology and ground-water resources of the Ahtanum Valley, Yakima County, Washington
B. L. Foxworthy
1962, Water Supply Paper 1598
The Ahtanum Valley covers an area of about 100 square miles in an important agricultural district in central Yakima County, Wash. Because the area is semiarid, virtually all crops require irrigation. Surface-water supplies are inadequate in most of the area, and ground water is being used increasingly for irrigation. The...
Effect of reservoir storage on peak flow
William D. Mitchell
1962, Water Supply Paper 1580-C
For observation of small-basin flood peaks, numerous crest-stage gages now are operated at culverts in roadway embankments. To the extent that they obstruct the natural flood plains of the streams, these embankments serve to create detention reservoirs, and thus to reduce the magnitude of observed peak flows. Hence, it is...
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...
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...
Biogeochemistry of vanadium
Helen L. Cannon
1962, Open-File Report 62-25
Vanadium is known to occur in soils as vanadates of copper, zinc, lead, uranium, ferric iron, manganese, calcium, and potassium. Vanadium replaces aluminum in clays and occurs in porphyrin complexes in bituminous sediments.Small amounts of vanadium are stimulating to plants; large amounts are toxic. Ten to 20 ppm vanadium in...
Relation between ground water and surface water in Brandywine Creek basin, Pennsylvania
F. H. Olmsted, A. G. Hely
1962, Professional Paper 417-A
The relation between ground water and surface water was studied in Brandywine Creek basin, an area of 287 square miles in the Piedmont physiographic province in southeastern Pennsylvania. Most of the basin is underlain by crystalline rocks that yield only small to moderate supplies of water to wells, but the...
Floods of December 1961 in Mississippi and adjoining states
James D. Shell
1962, Circular 465
Widespread floods occurred over parts of Mississippi, Louisiana, and Alabama after heavy rains during December 18, 1961. A series of low-pressure systems produced as much as 19 inches of rainfall in some areas. Heavy rainfall, 7 to 11 inches, on December 10 resulted in outstanding floods on small streams in...
