Flow resistance in sinuous or irregular channels
Luna Bergere Leopold, Ralph A. Bagnold, M. Gordon Wolman, Lucien M. Brush Jr.
1960, Professional Paper 282-D
The resistance to fully developed turbulent flow at constant depth in an open channel increases as the square of the mean velocity as long as the boundary conditions remain completely unchanged. The presence of the free water surface allows the possibility of departure from the relationship of resistance to the...
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...
Time, distance, and drawdown relationships in a pumped ground-water basin
Fred Kunkel
1960, Circular 433
Several reasonable values are assumed for coefficients of transmissibility and storage of lenticular alluvial deposits, These values when substituted in the Theis (1935) nonequilibrium formula as modified by Wenzel (1942) give curves from which time, distance, drawdown relationships are estimated....
Springs: their origin, development, and protection
G.H. Taylor
1960, Open-File Report 60-140
This paper has been prepared to describe springs briefly, to give some suggestions about developing and protecting them, and to list selected reports and books that contain more detailed explanations of springs and that describe how to develop and protect them from contamination....
Geology and ground-water resources of the Rawlins area, Carbon County, Wyoming
Delmar W. Berry
1960, Water Supply Paper 1458
The Rawlins area in west-central Carbon County, south-central Wyoming includes approximately 634 square miles of plains and valleys grading into relatively rugged uplifts. The climate is characterized by low precipitation, rapid evaporation, and a wide range of temperature. Railroading and ranching are the principal occupations in the area. The exposed...
Pumice and pozzolan deposits in the Lesser Antilles
Edwin Butt Eckel
1960, Open-File Report 60-48
Early in 1959 the International Cooperation Administration requested the U. S. Geological Survey to assign a geologist to a reconnaissance study of the pumice and pozzolan deposits of the Lesser Antilles. As a result, I made brief field examinations of all the reported deposits during the period May 25 -...
