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....
Determination of radium in water
Franklin Butt Barker, J. O. Johnson
1964, Water Supply Paper 1696-B
Radium isotopes are common radioactive constituents of natural waters. The concentration of radium-226 in potable water is of particular significance because this isotope is generally considered the most hazardous of all radionuclides with respect to ingestion. The approximate concentration of radium-226 is determined after coprecipitating radium with barium sulfate. The...
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...
Geology applied to study of coal mine bumps and mining methods at Sunnyside, Utah
Frank W. Osterwald, C. Richard Dunrud
1964, Open-File Report 64-122
Coal mine bumps are a serious hazard to life and property in the mines of east-central Utah. Research into geologic factors associated with these bumps indicates that the bumps are spatially and genetically related to structural and stratigraphic features. Some bumps are directly related to stress accumulation along faults, either...
Hydrology and hydrogeology of Navajo Lake, Kane County, Utah
Milton Theurer Wilson, Harold E. Thomas
1964, Professional Paper 417-C
Navajo Lake, whose entire outflow disappears underground, is on the high Markagurit Plateau where the average annual precipitation is more than 30 inches. It nestles among the headwaters of several streams that flow into arid regions where competition for municipal, industrial, and irrigation water sup- plies is very keen. Several...
Extending Darcy's concept of ground-water motion
H.E. Skibitzke
1964, Professional Paper 411-F
The tensor nature of permeability and its effect in a given ground-water flow regime have been acknowledged by various investigators. The effect on the spread of a given dissolved substance can be qualitatively discussed on the basis of the tensor characteristic of the permeability coefficient. The correlation between the dispersion...
