Water rights in areas of ground-water mining
Harold E. Thomas
1955, Circular 347
Ground-water mining, the progressive depletion of storage in a ground-water reservoir, has been going on for several years in some areas, chiefly in the Southwestern States. In some of these States a water right is based on ownership of land overlying the ground-water reservoir and does not depend upon putting...
Photogeologic procedures in geologic interpretation and mapping
Richard G. Ray
1955, Open-File Report 55-144
In the past few years increasing use has been made of aerial photographs for geologic interpretation and mapping within the U.S. Geological Survey. As a specialized technique in interpretation and mapping, however, photogeologic procedures were extensively used (1947-1953) in the Survey's geologic mapping of Naval Petroleum Reserve No. 4 in...
Computations of total sediment discharge, Niobrara River near Cody, Nebraska
Bruce R. Colby, C. H. Hembree
1955, Water Supply Paper 1357
A natural chute in the Niobrara River near Cody, Nebr., constricts the flow of the river except at high stages to a narrow channel in which the turbulence is sufficient to suspend nearly the total sediment discharge. Because much of the flow originates in the sandhills area of Nebraska, the...
Gravel and sand resources of the New England-New York region
Louis W. Currier
1955, Open-File Report 55-33
Deposits of sand and gravel are widespread in the New England-New York regions and constitute one of its principal mineral resources. Most of the pits are operated intermittently to supply local needs. Because of the great number and variety of known deposits, and because they have been worked at countless...
Reconnaissance of geology and ground water in the lower Grand River valley, South Dakota, with a section on Chemical quality of the ground water
Paul C. Tychsen, R.C. Vorhis, Eugene R. Jochens
1955, Water Supply Paper 1298
The area described in this report is the flood plain of the Grand River and the bordering benchlands in Perkins and Corson Counties, S. Dak., from a point about 6 miles west of the town of Shadehill to the confluence of the Grand and Missouri Rivers near Mobridge. The exposed bedrock...
Chemical quality of surface waters in Devils Lake basin, North Dakota
Herbert Swenson, Bruce R. Colby
1955, Water Supply Paper 1295
Devils Lake basin, a closed basin in northeastern North Dakota, covers about 3,900 square miles of land, the topography of which is morainal and of glacial origin. In this basin lies a chain of waterways, which begins with the Sweetwater group and extends successively through Mauvais Coulee, Devils Lake, East...
The natural channel of Brandywine Creek, Pennsylvania
M. G. Wolman
1955, Professional Paper 271
This study of the channel of Brandy wine Creek, Pennsylvania, consists of three parts. The first is an analysis of the changes which take place in the width, depth, velocity, slope of the water surface, suspended load, and roughness factor with changing discharge below the bankfull stage at each of...
Pleistocene geology of the southwestern Wind River Mountains, Wyoming
G.W. Holmes, J.H. Moss
1955, GSA Bulletin (66) 629-654
Patches of Buffalo till record the earliest glaciation in the southwestern Wind River Mountains. In places, these rest in youthful valleys cut in high gravel terrace. Two other younger and lower terraces are both topographically and stratigraphically associated with Buffalo till, which may indicate that the Buffalo advance was compound....
Salt-water encroachment as induced by sea-level excavation on Angaur Island
C.K. Wentworth, A.C. Mason, D.A. Davis
1955, Economic Geology (50) 669-680
Angaur, southwesternmost of the Palau Islands, 800 miles southwest of Guam, has an area of 3.2 square miles and consists of reef limestone of Pliocene through Recent age. In the northwestern part of the island a basin is formed by a ringlike ridge that has a maximum altitude of 150...
Sequence of alluviation along the Loup rivers, Valley County area, Nebraska
Robert D. Miller, Glenn R. Scott
1955, GSA Bulletin (66) 1431-1448
Alluviation along the North and Middle Loup rivers in Valley County, Nebraska, produced a series of alluvial silt beds on which are developed five interstadial soils of Brady (?), Cary and Mankato (?), Mankato (?), early Recent and late Recent age. No deposits of Illinoian age were found and in...
Violent mud-volcano eruption of lake city hot springs, northeastern California
Donald E. White
1955, GSA Bulletin (66) 1109-1130
During the night of March 1 and 2, 1951, an inconspicuous group of hot springs and small mud volcanoes in northeastern California burst into spectacular eruption, unequalled by other known mud volcanoes. The eruption cloud of steam, gases, and mud particles rose several thousand feet in the air and distributed...
Total sediment load measured in turbulence flume
Paul C. Benedict, Maurice L. Albertson, Donald Q. Matejka
1955, Transactions of the American Society of Civil Engineers (120) 457-484
The results of significant model tests in a glass-walled flume and prototype tests of a turbulence flume are presented. The velocity of flow and the transportation of the total sediment load in suspension were observed under varying conditions of flow. Also noted was the resistance to flow caused by vertical...
Determination of total sulfur content of sedimentary rocks by a combustion method
M. E. Coller, R. K. Leininger
1955, Analytical Chemistry (27) 949-951
Total sulfur has been determined in common sedimentary rocks by a combustion method. Sulfur contents range from 0.001 to 5.0%. Experiments show that the combustion method can be used in analyzing sedimentary rocks in which sulfur is present as sulfide, sulfate, or both. Pulverized samples from 0.100 to 0.500 gram...
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...
Field determination of microgram quantities of niobium in rocks
F. N. Ward, A. P. Marranzino
1955, Analytical Chemistry (27) 1325-1328
A rapid, simple, and moderately accurate method was needed for the determination of traces of niobium in rocks. The method developed is based on the reaction of niobium(V) with thiocyanate ion in a 4M hydrochloric acid and 0.5M tartaric acid medium, after which the complex is extracted with ethyl ether....
The sea lamprey
Vernon C. Applegate, James W. Moffett
1955, Scientific American (192) 36-41
Replicate samples of dehydrated :alfalfa-leaf meal were assayed for carotene content by four different analytical procedures. The results obtained by the modified A.O.A.C.method were significantly higher than those obtained by the other procedures....
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...
