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...
Manganese in the United States, exclusive of Alaska and Hawaii
Max D. Crittenden, Louis Pavlides
1962, Mineral Investigations Resource Map 23
The manganese deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. The deposits have been divided into several genetic types distinguished on the map by symbols. The principal distinction is between syngenetic deposits, in which the manganese was deposited contemporaneously with the enclosing...
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...
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...
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...
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...
Bentonite deposits of the northern Black Hills district, Wyoming, Montana, and South Dakota
Maxwell M. Knechtel, Sam H. Patterson
1962, Bulletin 1082-M
The northern Black Hills bentonite mining district includes parts of Crook County, Wyo., Carter County, Mont., and Butte County, S. Dak. Within this district, many beds of bentonite occur interspersed with sedimentary strata of Cretaceous age that have an average total thickness of about 3,000 feet and consist chiefly of...
