A national network of hydrological benchmarks
Luna Bergere Leopold
1962, Circular 460-B
We are engaged in great national programs of water control and development. An expanding population demands ever-increasing supplies of the natural resources which are to be found in or upon the landscape soil, water, minerals, food, timber, and fiber. By his works, by his extractions, man's mark upon his environment...
Silver in the United States, exclusive of Alaska and Hawaii
Edwin Thor McKnight, W.L. Newman, Harry Klemic, A. V. Heyl
1962, Mineral Investigations Resource Map 34
The productive silver districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. Only those districts known or believed to have contained 100,000 troy ounces or more silver are shown. Three size categories, based on production and estimated reserves, are distinguished and indicated by...
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...
Flow through openings in width constrictions
Jacob Davidian, P.H. Carrigan Jr., John Shen
1962, Water Supply Paper 1369-D
A highway embankment across a stream channel may have one or several bridge openings. In 1953, the pattern of flow through a single opening was quantitatively described by C. E. Kindsvater, R. W. Carter, and H. J. Tracy. The present investigation of the flow pattern at constrictions with two to...
Methods of measuring soil moisture in the field
A.I. Johnson
1962, Water Supply Paper 1619-U
For centuries, the amount of moisture in the soil has been of interest in agriculture. The subject of soil moisture is also of great importance to the hydrologist, forester, and soils engineer. Much equipment and many methods have been developed to measure soil moisture under field conditions. This report discusses...
An application of thermometry to the study of ground water
Robert Schneider
1962, Water Supply Paper 1544-B
Except for studies of temperature data related to ground-water developments that induce infiltration from streams, little attention has been given to the possibility of using temperature fluctuations as a tool for studying the elements of the hydrologic cycle involving ground water. The temperature of the water discharged from large installations that...
Floods in New Mexico, magnitude and frequency
Leon A. Wiard
1962, Circular 464
This report presents a method of determining the magnitude and frequency of floods that can be expected in New Mexico The discharge of the mean annual flood for various regions in the State is defined. Curves relate mean annual flood and drainage area. Drainage area was the only basin characteristic...
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...
Rainwater as a chemical agent of geologic processes; a review
Dorothy Carroll
1962, Water Supply Paper 1535-G
Chemical analyses of the rainwater collected at several localities are given to show the variations of the principal constitutents. In rock weathering and soil-forming processes, the chemical composition of rainwater has an important effect which has been evaluated for only a few arid areas. In humid regions the important amounts...
