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...
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....
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...
Inventory of published and unpublished chemical analyses of surface waters in the continental United States and Puerto Rico, 1961
Thomas H. Woodard, Sumner Griggs Heidel
1964, Water Supply Paper 1786
This inventory contains a list of published and unpublished chemical analyses obtained through September 30, 1961, by agencies associated with the Subcommittee on Hydrology. Bulletin 6 of Subcommittee on Hydrology includes references to all surface-water analyses for states east of the Mississippi River known to exist in the files of...
Amazon River investigations, reconnaissance measurements of July 1963
Roy Edwin Oltman, H. O’R. Sternberg, F.C. Ames, L.C. Davis
1964, Circular 486
The first measurements of the flow of the Amazon River were made in July 1963 as a joint project of the University of Brazil, the Brazilian Navy, and the U.S. Geological Survey. The discharge of the Amazon River at Obidos was 7,640,000 cfs at an annual flood stage somewhat lower...
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...
Determination of ammonium citrate-soluble cobalt in soils and sediments
Frank Cogswell Canney, G.A. Nowlan
1964, Open-File Report 64-30
A rapid field method for the determination of cold-extractable cobalt in soils and sediments has been developed for use in geochemical prospecting. Readily available cobalt is dissolved by treating the sample with an aqueous ammonium citrate-hydroxylamine hydrochloride solution; the filtered citrate extract is then treated with 2-nitroso1-naphthol to form a...
