Magnitude and frequency of floods in the United States, part 3–A. Ohio River Basin except Cumberland and Tennessee River Basins
Paul R. Speer, Charles R. Gamble
1965, Water Supply Paper 1675
This report presents a means of determining the probable magnitude and frequency of floods of any recurrence interval from 1.1 to 50 years at most points on streams in the Ohio River basin except Cumberland and Tennessee River basins.Curves are defined that show the relation between the drainage area and...
Bauxite and Kaolin Deposits of the Irwinton district, Georgia
Walter B. Lang, Walter C. Warren, Raymond M. Thompson, Elizabeth F. Overstreet
1965, Bulletin 1199-J
The Irwinton district is in the central part of Georgia at the inner margin of the Coastal Plain province. The oldest rocks exposed in the district are crystalline rocks of the Piedmont province. They are unconformably overlain by nonmarine sedimentary strata of Late Cretaceous age, including gravel, micaceous sand, and...
Density comparison method for the measurement of isotopic variations in prepared waters
Joseph Howard McCarthy Jr., Thomas Seward Lovering, Herbert Williams Lakin
1965, Open-File Report 65-103
The falling-drop method of density determination has been modified so that the densities of a standard and a sample water are compared simultaneously. A constant temperature bath that does not vary more than 0.0001°C and an accurate double micropipet are described. The method has sufficient sensitivity and precision to distinguish...
Plant microfossils of the Hazard No. 7 coal, Perry County, Kentucky
Robert M. Kosanke
1965, Open-File Report 65-89
The cooperative mapping program between the Kentucky Geological Survey and the U. S. Geological Survey has yielded a number of interesting and valuable by-products. As a part of the stratigraphic studies involving Carboniferous coal fields, R. M. Kosanke has been involved in a detailed analysis of spore floras from various...
Determination of uranium in natural waters
Franklin Butt Barker, J. O. Johnson, K.W. Edwards, B.P. Robinson
1965, Water Supply Paper 1696-C
A method is described for the determination of very low concentrations of uranium in water. The method is based on the fluorescence of uranium in a pad prepared by fusion of the dried solids from the water sample with a flux of 10 percent NaF 45.5 percent Na2CO3 , and...
