Reconnaissance geologic map and geochemical analyses of stream-sediment and rock samples of the Anchorage A-6 quadrangle, Alaska
Sandra H. B. Clark, Martha E. Yount
1972, Miscellaneous Field Studies Map 351
A reconnaissance geologic map and analytical data for 70 stream-sediment samples and 34 rock samples for the Anchorage A-6 1:63,360 scale quadrangle are presented in this report, together with a statistical treatment of the geochemical data. The bedrock was mapped and samples collected during the summers of 1969, 1970, and...
Landslide susceptibility in San Mateo County, California
Earl E. Brabb, Earl H. Pampeyan, Manuel G. Bonilla
1972, Miscellaneous Field Studies Map 360
Information on areas susceptible to failure by landsliding is available in many general geologic maps and reports.  However, it is commonly presented in complex, technical language, together with data not connected with slope stability.  This derivative map is intended to convey such information in nontechnical form so that it will...
Water resources data for Michigan, water year 1971; Part 1, Surface water records
Water Resources Division, U.S. Geological Survey
1972, Water Data Report MI-71-1
Surface-water records for the 1971 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Michigan are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water...
Test observation well near Almira, Washington: description and preliminary results
Kenneth L. Walters
1972, Open-File Report 72-440
A 750-foot test-observation well drilled bear Almira, Wash., is one of several drilled to date (1971) in selected areas if the State. The test wells provide information on ground-water conditions where large-scale pumping from wells is rapidly increasing or ids expected to increase, but where data available from existing wells...
Tectonic map of Liberia based on geophysical and geological surveys
John Charles Behrendt, Cletus S. Wotorson
1972, Open-File Report 72-32
Interpretation of the results of aeromagnetic, total-gamma radioactivity, and gravity surveys combined with geologic data for Western Liberia from White and Leo (1969) and other geologic information allows the construction of a tectonic map of Liberia. The map approximately delineates the boundaries between the Liberian (ca. 2700 m.y.) province in...
Effect of aging on aluminum hydroxide complexes in dilute aqueous solutions
Ross Wilbert Smith, John David Hem
1972, Water Supply Paper 1827-D
Aqueous aluminum solutions containing 4?10 -5 mole/liter aluminum and a constant total ionic strength of 10 -2, but with varying ratios of hydroxide to aluminum (OH:Al), were prepared. Progress of these solutions toward equilibrium conditions over aging periods of as much as 2 years was studied by determining the composition...
Travel time for solutes, upper Sabine River basin, Texas, April 16-30, 1972
Willard B. Mills
1972, Open-File Report 72-257
The U.S. Geological Survey, in cooperation with the Sabine River Compact Administration, conducted time-of-travel studies in the Sabine River Basin on April 16-30, 1972. One study was made on the main stem of the Sabine River in four reaches from Lake Tawakoni to Toledo Bend Reservoir, a distance of 219...
An evaluation of water-quality records for Texas streams
J.F. Blakey, R.O. Hawkinson, T.D. Steele
1972, Open-File Report 72-37
Chemical data for 12 streamflow-sampling stations in Texas, each having from 8 to 24 years of available historical records, were analyzed to determine functional relationships between concentrations of the major inorganic constituents and specific conductance or stream discharge. Regression equations for each station were derived by using data for an...
Artificial recharge in the upper Santa Ana Valley, southern California
Joe A. Moreland
1972, Open-File Report 72-261
Artificial recharge has long been an integral part of water-supply management in the upper Santa Ana Valley. About 7,500 acres of unlined channels and 2,590 acres in 60 off-channel recharge facilities are available for water spreading.To estimate potential infiltration rates for the recharge facilities, 63 single-ring infiltrometer tests were conducted...
Applications of the generalized information processing system (GIPSY)
D.W. Moody, Olaf Kays
1972, Open-File Report 72-260
The Generalized Information Processing System (GIPSY) stores and retrieves variable-field, variable-length records consisting of numeric data, textual data, or codes. A particularly noteworthy feature of GIPSY is its ability to search records for words, word stems, prefixes, and suffixes as well as for numeric values. Moreover, retrieved records may be...
New Mexico district work-effort analysis computer program
W. L. Hiss, A.P. Trantolo, J.L. Sparks
1972, Open-File Report 72-165
The computer program (CAN 2) described in this report is one of several related programs used in the New Mexico District cost-analysis system. The work-effort information used in these programs is accumulated and entered to the nearest hour on forms completed by each employee. Tabulating cards are punched directly from...
An inventory of published and unpublished fluvial-sediment data for California, 1956-70
George Porterfield
1972, Open-File Report 72-300
This inventory was prepared to provide a convenient reference to published and unpublished fluvial-sediment data for water years 1956-70, and updates substantially previous inventories. Sediment stations are listed in downstream order, and an alphabetical list of stations is also included. Figure 1 shows the approximate location of sediment stations in...
