Water resources of the Upper Colorado River Basin - basic data
William Vaughn Iorns, C. H. Hembree, D. A. Phoenix, G.L. Oakland
1964, Professional Paper 442
This is the basic data section of a report by the U.S. Geological Survey on the water resources of the Upper Colorado River Basin. This section contains tables of duration of water discharge at 176 stream-gaging sites, monthly and annual summaries of chemical quality and sediment data at sites of...
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...
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....
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...
