Lithologic variations in slope development theory
Adrian E. Scheidegger
1964, Circular 485
This paper presents a comprehensive review and amplification of the writer's earlier slope development theory. In particular, the influence of lithology on evolving slope profiles is investigated and calculations are made for various conditions, such as presence of caprock, soft bottom, and hard and soft intermediate layers....
Magnitude and frequency of floods in Alaska south of the Yukon River
Vernon Kenneth Berwick, Joseph M. Childers, M.A. Kuentzel
1964, Circular 493
This report presents a method for evaluating the magnitude and frequency of floods on the basis of the analysis of flood records. One composite frequency curve is applied to the entire study region. This curve relates floods of various magnitudes at any site within the region to probable recurrence intervals...
Exploratory laboratory study of lateral turbulent diffusion at the surface of an alluvial channel
William W. Sayre, A.R. Chamberlain
1964, Circular 484
In natural streams turbulent diffusion is one of the principal mechanisms by which liquid and suspended-particulate contaminants are dispersed in the flow. A knowledge of turbulence characteristics is therefore essential in predicting the dispersal rates of contaminants in streams. In this study the theory of diffusion by continuous movements for...
A magnetic anomaly of possible economic significance in southeastern Minnesota
Isidore Zietz
1964, Circular 489
An aeromagnetic survey in southeastern Minnesota by the U. S. Geological Survey in cooperation with the State of Minnesota has revealed a high-amplitude, linear, and narrow magnetic feature that suggests a possible source of Precambrian iron-formation of economic value. For the past few years the U. S. Geological Survey has...
Preliminary report on the geologic and geophysical investigations of the Loveland Basin landslide, Clear Creek County, Colorado
Charles Sherwood Robinson, R. D. Carroll, Fitzhugh T. Lee
1964, Open-File Report 64-135
Geologic and geophysical investigations of the Loveland Basin landslide, which formed at the cut for the east portal of the Straight Creek tunnel, were made by the U.S. Geological Survey in cooperation with the U.S. Bureau of Public Road and the Colorado Department of Highways. The investigations indicate that the...
Seismic study of coal mine bumps, Carbon and Emery Counties, Utah
C. Richard Dunrud, Frank W. Osterwald
1964, Open-File Report 64-45
A continuously recording seismic network was constructed in 1962 by the U.S. Geological Survey to locate epicenters and record incidence of bumps (bounces, rock bursts) that occur in the bituminous coal mines of the Book Cliffs coal field near Sunnyside, Utah. The coal is mined because of its value as...
Magnetic properties of Pd, Pd-H and Pd-D from 300 degrees K to 4.2 degrees K
Arthur N. Thorpe
1964, Open-File Report 64-151
The magnetic properties of many substances first studied seriously by Faraday have played an important role in our modern technology. In particular, the magnetic properties of the transition elements are of great importance in the understanding of the electronic band form of these elements. Once the electronic band form is...
Seismic refraction survey in the Great Miami River Valley and vicinity, Montgomery, Warren, and Butler Counties, Ohio
Joel S. Watkins, Andrew M. Spieker
1964, Open-File Report 64-161
As part of a continuing program to define the thickness and extent of water-bearing sand and gravel deposits in southwestern Ohio, the U.S. Geological Survey, in cooperation with the Ohio Division of Water and The Miami Conservancy District, completed a seismic refraction survey of the Great Miami River valley and...
