Flood control problems
Luna Bergere Leopold, Thomas Maddock Jr.
1955, Journal of Soil and Water Conservation in India (3) 169-173
Throughout the world, alluvial soils are among the most fertile and easiest cultivated. Alluvial valleys are routes for transportation either by water or by road and railroad. Rivers are sources of water, a necessity of life. But these river valleys and alluvial deposits, which have so many desirable characteristics and...
Rapid determination of water in silicate rocks
Leonard Shapiro, W. W. Brannock
1955, Analytical Chemistry (27) 560-562
A rapid and simple method for the determination of total water in silicate rocks has been developed by modifying the Penfield procedure. In this method, the time required for a single determination has been reduced to less than 10 minutes. Comparison of the data obtained by this modification and the...
Determination of boron in silicates after ion exchange separation
Henry Kramer
1955, Analytical Chemistry (27) 144-145
Existing methods for the determination of boron in silicates are not entirely satisfactory. Separation as the methyl ester is lengthy and frequently erratic. An accurate and rapid method applicable to glass, mineral, ore, and water samples uses ion exchange to remove interfering cations, and boron is determined titrimetrically in the...
Sediment investigations of the Platte River near Overton, Nebraska
C.D. Albert, H.P. Guy
1955, Report
This report contains results of sediment-transport investigations on the Platte River near Overton,. Nebr. from January 1950 to September 1953. The basic data of suspended-sediment studies, results of bed-material analyses, and determinations of water-surface slopes from staff readings are given. The data indicate that a reliable determination of suspended sediment, hence...
Ground water resources of southeastern Oakland County, Michigan
J.G. Ferris, E.M. Burt, G.J. Stramel, E. G. Crosthwaite
1954, Report
The area covered by this report comprises a square which measures three townships on a side and enclose 318 square miles in southeastern Oakland County. The investigation of the ground-water resources of this area was made by the U.S. Geological Survey in cooperation with the Detroit Metropolitan Area Regional Planning...
Geology and ground-water resources of Wichita and Greeley Counties, Kansas
G.C. Prescott Jr., J.R. Branch, W.W. Wilson
1954, Kansas Geological Survey Bulletin (108)
This report describes the geography, geology, and ground-water resources of Wichita and Greeley counties in western Kansas. The area consists of a flat to gently rolling plain, which slopes eastward [at] about 15 feet per mile. A short reach of Ladder Creek (Beaver) is the only perennially flowing stream in...
Infectious diseases of Pacific salmon
Robert R. Rucker, B. J. Earp, E. J. Ordal
1954, Transactions of the American Fisheries Society (83) 297-312
Investigations on infectious diseases of Pacific salmon due to micro-organisms other than viruses are reviewed. The etiological agents include trematodes, fungi, protozoa and bacteria. Bacteria have been found to be the most important agents of disease in the several species of Pacific salmon. Kidney disease, due to a small, unnamed...
A virus disease of sockeye salmon: Interim report
S.W. Watson, R.W. Guenther, R.R. Rucker
1954, Special Scientific Report - Fisheries 138
Since 1951 a disease, usually occurring in late spring or early summer, has caused severe losses in 3- to 12-month-old fingerling sockeye salmon in hatcheries in the State of Washington. The disease is characterized by an explosive outbreak, mortality usually 80 percent or greater, and a residual spinal deformity in...
Summary of geology and ground-water resources of the Eastern Shore peninsula, Virginia: a preliminary report
Allen Sinnott, G. Chase Tibbitts Jr.
1954, Virginia Division of Geology Mineral Resources Circular 2
The U.S. Geological Survey, in cooperation with the Virginia Division of Geology (Virginia Division of Mineral Resources), conducted an investigation of the geology and ground-water resources of the Coastal Plain of Virginia. This report summarizes preliminary findings from exploratory test drilling done to ascertain whether there are any satisfactory water-bearing...
Geology of the Starr molybdenum mine, Okanogan County, Washington
S.C. Creasey
1954, Book chapter, Molybdenum occurrences of Washington (Report of Investigations 18)
The Starr molybdenum mine, Okanogan County, Wash., is about 5 airline miles west of Tonasket in the north-central part of the State. The mineralized zone has been explored to a depth of 250 feet by means of three adit levels, one sublevel, and a raise which connects two of the...
Progress report on selected ground-water basins in Utah
H.A. Waite, W.B. Nelson, B. E. Lofgren, John Henry Frederick Feth
1954, Technical Publication 9
This technical publication consists essentially of the interpretation of data collected in connection with a detailed inventory of ground-water pumpage and water-level trends in four irrigation districts in southern Utah. Much of this information was assembled in a preliminary report entitled "Inventory of ground-water pumpage in three irrigation districts in...
Haemoproteus infections in waterfowl
C. M. Herman
1954, Proceedings of the Helminthological Society of Washington (21) 37-42
It is proposed that Haemoproteus nettionis (Johnston and Cleland, 1909) Coatney, 1936 be accepted as the correct name for the Haemoproteus of Anatidae. A list of synonyms and amended description of the parasite is given. Infections are reported from wood ducks (Aix sponsa) and from domestic ducks and geese, the...
Uranium-bearing lignite and its relation to the White River and Arikaree formations in northwestern South Dakota and adjacent states
N.M. Denson, G.O. Bachman, H. D. Zeller
1954, Trace Elements Investigations 467
In northwestern South Dakota and adjacent areas uranium-bearing lignite beds occur at many horizons in the Hell Creek formation of late Cretaceous age and the overlying Ludlow, Tongue River, and Sentinel Butte members of the Fort Union formation of Paleocene age. Uranium analyses of 275 surface and auger samples and...
A postglacial chronology for some alluvial valleys in Wyoming
Luna Bergere Leopold, John P. Miller
1954, Water Supply Paper 1261
Alluvial terraces were studied in several major river basins in eastern Wyoming. Three terraces are present along nearly all the streams and large tributaries. There are several extensive dissected erosion surfaces in the area, but these are much older than, and stand well above, the recent alluvial terraces with which...
