Water Resources Division, U.S. Geological Survey
1961, Professional Paper 424-B
The scientific and economic results of work by the United States Geological Survey during the fiscal year 1961, the 12 months ending June 30, 1961, will be summarized in four volumes of which this is the first. This volume includes 146 short papers on a variety of subjects in the...
Water levels in observation wells in Santa Barbara County, California, in 1960
P.M. Merritt
1961, Open-File Report 61-96
Investigation of the ground-water resources of Santa Barbara County was continued during 1960 by the U. S. Geological Survey in cooperation with the Santa Barbara County Water Agency. Monthly water-level measurements were made in 193 wells, in 9 of which automatic water-level recorders were operated. Earlier measurements, covering the period...
Progress in the application of landform analysis in studies of semiarid erosion
Stanley Alfred Schumm, R. F. Hadley
1961, Circular 437
The analysis of topographic and hydrologic data gathered during studies of erosion in semiarid areas of Western United States show the following relation: (a) Mean annual sediment yield from small drainage basins is related to a ratio of basin relief to length; (b) mean annual runoff from small drainage basins...
Floods in Wisconsin: Magnitude and frequency
D.W. Ericson
1961, Open-File Report 61-44
Flood data from gaging stations on Wisconsin rivers and streams are listed in this report. From these data, composite frequency curves were defined which express the ratio of floods of various recurrence intervals to the mean annual flood. Multiple correlation techniques were used to obtain formulas that relate the basin...
Data on wells at Ladd Air Force Base, Alaska
Alvin J. Feulner
1961, Open-File Report 61-50
Ladd Air Force Base, in central Alaska, obtains its water supply from wells. A tabulation of 104 wells gives available data on depth, diameter, yield, and depth of permafrost encountered. Also given are 23 well logs and 21 chemical analyses of well waters and treated waters from Ladd Air Force...
Floods in Arkansas, magnitude and frequency
James L. Patterson
1961, Open-File Report 62-99
This report presents methods by which the magnitude and frequency of expected floods for most streams in Arkansas may be determined. Flood data have been used to define flood-frequency curves applicable to the State.Composite frequency curves have been defined showing the relation of the mean annual flood to floods having...
