The Foraminiferal Genus Orbitolina in North America
Raymond Charles Douglass
1960, Professional Paper 333
The foraminiferal genus Orbitolina has been useful as an index fossil in the Cretaceous rocks of the circumglobal equatorial belt for nearly a century. In Europe and the Near and Middle East enough work has been done on the species to allow their use for approximate correlations within the Cretaceous...
Flood-frequency analyses, Manual of Hydrology: Part 3
Tate Dalrymple
1960, Water Supply Paper 1543-A
This report describes the method used by the U.S. Geological Survey to determine the magnitude and frequency of momentary peak discharges at any place on a stream, whether a gaging-station record is available or not. The method is applicable to a region of any size, as a river basin or...
Evaporation control research, 1955-58
Robert R. Cruse, Guy Earl Harbeck
1960, Water Supply Paper 1480
One hundred fifty-two compounds and compositions of matter were screened as potential evaporation retardants. The homologous straight-chain fatty alkanols are considered the best materials for retardants. Several methods of application of the alkanols to the reservoir surface were investigated. Although wick-type drippers for the application of liquids and cage rafts...
Borehole geophysical methods for analyzing specific capacity of multiaquifer wells : ground-water hydraulics
Gordon D. Bennett, Eugene P. Patten Jr.
1960, Water Supply Paper 1536-A
Conventional well-logging techniques, combined with measurements of flow velocity in the borehole, can provide information on the discharge-drawdown characteriBtic8 of the several aquifers penetrated by a well. The information is most conveniently presented in a graph showing aquifer discharges as functions of the water level in the well at a...
