Storage of low-level radioactive wastes in the ground; hydrogeologic and hydrochemical factors
Stavros Stefanu Papadopulos, Isaac Judah Winograd
1974, Open-File Report 74-344
The status of mathematical simulation techniques, as they apply to radioactive waste burial sites, is briefly reviewed, and hydrogeologic and hydrochemical data needs are listed in order of increasing difficulty and cost of acquisition. Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be...
Straight line fitting of an observation path by least normal squares
William H. Kirby
1974, Open-File Report 74-187
In curtain hydro graphic problems, and perhaps in other geophysical problems, information must be collected as profiles along straight-line courses. When the inevitable deviations from perfect linearity occur, one must then find the straight line course that best approximates the actual observation path. Classical least squares (regression) does not solve...
Summary of activities, U.S. Geological Survey Saudi Arabian project, 1950 to 1974
Thor H. Kiilsgaard
1974, Open-File Report 74-129
The U. S. Geological Survey (USGS) first began work in the Kingdom of Saudi Arabia in 1950 under the sponsorship of the Ministry of Finance and National Economy. The basic objective of the work was to investigate the mineral and water resource potential in western Saudi Arabia, but little was...
Geothermal systems of northern Nevada
Richard Kenneth Hose, Bruce Edward Taylor
1974, Open-File Report 74-271
Hot springs are numerous and nearly uniformly distributed in northern Nevada. Most occur on the flanks of basins, along Basin and Range (late Miocene to Holocene) faults, while some occur in the inner parts of the basins. Surface temperatures of the springs range from slightly above ambient to, boiling; some...
Sediment characteristics of five streams near Harrisburg, Pa., before highway construction
Lloyd A. Reed
1974, Open-File Report 74-140
Rainfall, streamfiow, sediment, and turbidity data are being collected as part of a study to evaluate the effects of highway construction on sediment discharge. The study is also designed to determine the effectiveness of different erosion-control measures in reducing sediment discharges. The study area, near Enola, Pa., consists of five...
Time-dependent spectral analysis of thirty-one strong-motion earthquake records
Virgilio Perez
1974, Open-File Report 74-48
Velocity response spectral analysis as a function of time for 5 percent critical damping is presented for the horizontal components of thirty-one earthquake records (61 components). A nomograph that allows conversion of the velocity response envelope to a displacement response envelope and a pseudo-absolute acceleration response envelope spectrum is also...
Environmental impact analysis; the example of the proposed Trans-Alaska Pipeline
David A. Brew
1974, Circular 695
The environmental impact analysis made as required by the National Environmental Policy Act of 1969 for the proposed trans-Alaska pipeline included consideration of the (1) technologically complex and geographically extensive proposed project, (2) extremely different physical environments across Alaska along the proposed route and elsewhere in Alaska and in Canada...
Mineral resources of Antarctica
Nancy A. Wright, Paul L. Williams, editor(s)
1974, Circular 705
Although the existence of mineral deposits in Antarctica is highly probable, the chances of finding them are quite small. Minerals have been found there in great variety but only as occurrences. Manganese nodules, water (as ice), geothermal energy, coal, petroleum, and natural gas are potential resources that could perhaps be...
Floods in Indiana: technical manual for estimating their magnitude and frequency
L.G. Davis
1974, Circular 710
This manual provides methods for estimating the magnitude and frequency of floods on unregulated and unurbanized streams in Indiana that drain at least 15 square miles (38.8 square kilometres). The methods provide the design engineer with a means of estimating flood frequencies without having to analyze the records at individual...
Seismic hazards and land-use planning
Donald R. Nichols, Jane M. Buchanan-Banks
1974, Circular 690
Basic earth-science data are necessary for a realistic assessment of seismic hazards and as a basis for limiting corrective land-use controls only to those areas of greatest hazard. For example, the location, character, and amount of likely displacement and activity of surface faulting can be predicted if detailed geologic maps...
Large rivers of the United States
Kathleen T. Iseri, Walter Basil Langbein
1974, Circular 686
Information on the flow of the 28 largest rivers in the United States is presented for the base periods 1931-60 and 1941-70. Drainage area, stream length, source, and mouth are included. Table 1 shows the average discharge at downstream gaging stations. Table 2 lists large rivers in order of average...
Selenium, fluorine, and arsenic in surficial materials of the conterminous United States
Hansford T. Shacklette, Josephine G. Boerngen, John R. Keith
1974, Circular 692
Concentrations of selenium, fluorine, and arsenic in 912, 911, and 910 samples, respectively, of soils and other regoliths from sites approximately 50 miles (80 km) apart throughout the United States are represented on maps by symbols showing five ranges of values. Histograms of the concentrations of these elements are also...
Floods of September-October 1967 in south Texas and northeastern Mexico
Elmer E. Schroeder, R.U. Grozier, D. C. Hahl, A.E. Hulme
1974, Water Supply Paper 1880-B
Floods produced by Hurricane Beulah during September and October 1967 were outstanding because of the magnitude of the stage and discharge and because of the number of river basins affected. Previously known maximum stages were exceeded, at the downstream station, in five river basins in Texas by amounts ranging from...
Water quality of hydrologic bench marks; an indicator of water quality in the natural environment
James E. Biesecker, Donald K. Leifeste
1974, Circular 460-E
Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very...
