Recent activity of glaciers of Mount Rainier, Washington
Robert S. Sigafoos, E. L. Hendricks
1972, Professional Paper 387-B
Knowing the ages of trees growing on recent moraines at Mount Rainier, Wash., permits the moraines to be dated. Moraines which are ridges of boulders, gravel, sand, and dust deposited at the margins of a glacier, mark former limits of a receding glacier. Knowing past glacial activity aids our understanding...
Fluvial sediment in Salem Fork watershed, West Virginia
R.F. Flint
1972, Water Supply Paper 1798-K
Suspended sediment discharged from the 8.32-square-mile Salem Fork study area in Harrison County, W. Va., averaged 3,500 tons per year during the first 4-year period of investigation and 1,770 tons per year during the second 4-year period. The difference as attributed to increased flow control, effected by the completion of...
Electric analog studies of flow to wells in the Punjab aquifer of West Pakistan
Maurice John Mundorff, G.D. Bennett, Masood Ahmad
1972, Water Supply Paper 1608-N
A series of experiments was performed with a steady-state electric analog simulating a cylindrical segment of the aquifer underlying the plains of the Punjab region of West Pakistan. In most of the experiments recharge was assumed to be from the surface, within a specified radius of influence, and distributed uniformly...
Water resources data for Mississippi, water year 1971
Water Resources Division, U.S. Geological Survey
1972, Water Data Report MS-71-1
Water resources data for the 1971 water year for Mississippi including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. In Part 1, records are included...
Map showing length of freeze-free season in the Salina quadrangle, Utah
1972, IMAP 591-E
In general, long freeze-free periods occur at low elevations, and short freeze-free periods occur at high elevations. But some valley floors have shorter freeze-free seasons than the glancing foothills because air cooled at high elevations flows downward and is trapped in the valleys. This temperature pattern occurs in the western...
Regional and other general factors bearing on evaluation of earthquake and other geologic hazards to coastal communities of southeastern Alaska
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-230
The great Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in seismically active regions. As a result, nine communities in southeastern Alaska were selected for reconnaissance investigations as an integral part of an overall program to evaluate earthquake and other geologic hazards...
Low-flow investigations
H. C. Riggs
1972, Techniques of Water-Resources Investigations 04-B1
This manual describes methods of defining the low-flow characteristics of streams, shows how certain basin characteristics influence the mean and variability of annual low flows, and recommends procedures for data collection, analysis, and reporting....
Ground-water levels in observation wells in Oklahoma, 1969-70
R.L. Moore
1972, Open-File Report 72-463
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies;...
Map showing springs in the Salina quadrangle, Utah
1972, IMAP 591-G
A spring is “a place where, without the agency of man, water flows from a rock or soil upon the land or into a body of surface water” (Meinzer, 1923, p. 48).About 450 springs are located on this map. Locations and names are from the U.S. Forest Service maps (1963,...
The hydraulic geometry of some Alaskan streams south of the Yukon River
William W. Emmett
1972, Open-File Report 72-108
Channel geometry surveys were conducted to determine bankfull stage, discharge, and other hydraulic parameters at 22 locations along the proposed route of the trans-Alaska pipeline corridor south of the Yukon River. Combined with the records from gaging stations located at some of the sites, the data are sufficient to describe...
Falling-stream turbidimeter as a means of measuring sediment concentrations in streams
Harold P. Guy, Richard C. Olson
1972, Report
An optical (photocell) sensing device was used to measure the relative transparency characteristics of sediment suspensions with a view toward improving our ability to measure the temporal variations of suspended-sediment concentration moving in streams. The instrument used was a commercial "falling stream" turbidimeter that measured the relative transparency of a...
Preliminary mariner 9 report on the geology of Mars
John F. McCauley, M. H. Carr, J.A. Cutts, W.K. Hartmann, Harold Masursky, D.J. Milton, R.P. Sharp, Don E. Wilhelm
1972, Icarus (17) 289-327
Mariner 9 pictures indicate that the surface of Mars has been shaped by impact, volcanic, tectonic, erosional and depositional activity. The moonlike cratered terrain, identified as the dominant surface unit from the Mariner 6 and 7 flyby data, has proven to be less typical of Mars than previously believed, although...
The martian atmosphere: Mariner 9 television experiment progress report
C.B. Leovy, G.A. Briggs, A.T. Young, B.A. Smith, James B. Pollack, E.N. Shipley, R.L. Wildey
1972, Icarus (17) 373-393
Atmospheric phenomena appearing in the Mariner 9 television pictures are discussed in detail. The surface of the planet was heavily obscured by a global dust storm during the first month in orbit. Brightness data during this period can be fitted by a semi-infinite...
Ground-water outflow from Chino Basin, Upper Santa Ana Valley, southern California
James J. French
1972, Water Supply Paper 1999-G
Ground-water outflow from Chino basin was calculated ,by a direct method using the equation Q = PIA, in which Q is the quantity of ground-water outflow, P is the average coefficient of permeability of the sediments through which the flow occurs, I is the average hydraulic gradient, and A is...
Floods in Arkansas, magnitude and frequency characteristics through 1968
James L. Patterson
1971, Arkansas Geological Commission Water Resources Circular 11
Techniques are presented for estimating the magnitude and frequency of floods on Arkansas streams. Modern topographic maps now available and computer techniques facilitate in making a comprehensive analysis in which physical and climactic characteristics of river basins are related to flood characteristics at gaging stations. Equations derived from the analysis...
Relation of drainage problems to high ground-water levels, Coconut Grove area, Oahu, Hawaii
L.A. Swain, C.J. Huxel Jr.
1971, Open-File Report 72-365
Purpose and Scope In 1969, hydrologic data-collection sites were established in and around the Coconut Grove area for the purpose of measuring directly the relationship between rainfall, runoff, ground-water levels, the level of water in Kawainui Swamp and the canals, and tidal fluctuations. The primary objective was to identify the causes...
Selected fluvial monazite deposits in the southeastern United States
William C. Overstreet, A. M. White, P. K. Theobald, D. W. Caldwell
1971, Open-File Report 71-222
Farther southwest in Georgia, around Griffin and Zebullon, along streams tributary to the Flint River in the monazite belt the flood plains are generally small and discontinuous, and only about 1 percent of the sediment is gravel. The area between Griffin, Zebullon, and the Flint River is underlain by biotite...

Appraisal of streamflow in Tualatin River basin, Washington County, Oregon
C. H. Swift III
1971, Open-File Report 71-275
This report describes the within-year time distribution of streamflow; the magnitude and frequency of annual minimum, mean, and maximum flows; and the within-year storage required to sustain selected flows in the Tualatin River basin. The report does not include an appraisal of instantaneous peak discharges in the basin.  Data were derived by statistical methods and...
