Water-supply possibilities at Capitol Reef National Monument, Utah
I. Wendell Marine
1962, Water Supply Paper 1475-G
A water supply of 50 gpm (gallons per minute) is estimated to be sufficient to supply the present and future water demand at the monument. The Coconino sandstone of Permian age seems to be capable of yielding this quantity to a well between 1,500 and 2,700 feet deep in the...
Evolution of methods for evaluating the occurrence of floods
M. A. Benson
1962, Water Supply Paper 1580-A
A brief summary is given of the history of methods of expressing flood potentialities, proceeding from simple flood formulas to statistical methods of flood-frequency analysis on a regional basis. Current techniques are described and evaluated. Long-term flood records in the United States show no justification for the adoption of a...
Salinity of the Delaware Estuary
Bernard Cohen, Leo T. McCarthy Jr.
1962, Water Supply Paper 1586-B
The purpose of this investigation was to obtain data on and study the factors affecting the salinity of the Delaware River from Philadelphia, Pa., to the Appoquinimink River, Del. The general chemical quality of water in the estuary is described, including changes in salinity in the river cross section and...
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...
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...
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...
