Geology and ground-water resources of Fond du Lac County, Wisconsin
Thomas G. Newport
1962, Water Supply Paper 1604
The principal water-bearing rocks underlying Fond du Lac County, Wis., are sandstones of Cambrian and Ordovician age and dolomite of Silurian age. Other aquifers include dolomite of Ordovician age and sand. and gravel of Quaternary age. Crystalline rocks of Precambrian age, which underlie all the water-bearing formations, form a practically...
A formula for computing transmissibility causing maximum possible drawdown due to pumping
G.M. Robinson, Herbert E. Skibitzke
1962, Water Supply Paper 1536-F
By modifying the Theis nonequilibrium formula a relation is found in which the maximum possible drawdown is expressed in terms of a unique value for the aquifer coefficient of transmissibility. The relation is valid for any specified period and rate of pumping, for a given aquifer coefficient of storage, and...
Ground-water provinces of Brazil
Robert Schneider
1962, Water Supply Paper 1663-A
As part of a study of the status of investigations and development of ground water in Brazil, made under the auspices of the United States International Cooperation Administration and with the cooperation of the Government of Brazil, the country was divided into seven ground-water provinces. The identification and delineation of...
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...
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...
Explorations for water supplies on the public domain, 1960
William Stewart Eisenlohr
1962, Circular 461
In making reconnaissances for water supplies on the public domain as part of the Soil and Moisture Conservation Program of the Department of the Interior, the Geological Survey obtains information on the availability of water that is useful for other purposes or in other areas. This report contains the information...
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...
Data on uranium and radium in ground water in the United States, 1954 to 1957
R. C. Scott, F. B. Barker
1962, Professional Paper 426
This report is one of a series resulting from a study by the U.S. Geological Survey to determine the occurrence and distribution of naturally radioactive substances in water. From 1954-57 uranium and radium concentrations were determined in 561 samples, mainly of ground water, having wide geologic and geographic distribution. These...
The man and the hill
Luna Bergere Leopold
1962, Circular 460-A
He was sitting on a large slab of rock. As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed...
