Availability of ground water in parts of the Acoma and Laguna Indian Reservations, New Mexico
George A. Dinwiddie, Ward Sundt Motts
1964, Water Supply Paper 1576-E
The need for additional water has increased in recent years on the Acoma and Laguna Indian Reservations in west-central New Mexico because the population and per capita use of water have increased; the tribes also desire water for light industry, for more modern schools, and to increase their irrigation program....
Sea water in coastal aquifers
Hilton H. Cooper
1964, Water Supply Paper 1613-C
Investigations in the coastal part of the Biscayne aquifer, a highly productive aquifer of limestone and sand in the Miami area, Florida, show that the salt-water front is dynamically stable as much as 8 miles seaward of the position computed according to the Ghyben-Herzberg principle. This discrepancy results, at least...
The effect of artesian-pressure decline on confined aquifer systems and its relation to land subsidence
J. H. Green
1964, Water Supply Paper 1779-T
Ground water in the Southwestern United States is derived chiefly from unconsolidated to semiconsolidated alluvial deposits. Where these deposits contain confined water, they may be susceptible to compaction and related land- surface subsidence, if artesian pressures are reduced. Compaction of artesian-aquifer systems can be estimated from core tests if the...
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....
Hydrogeologic reconnaissance of Poro Point and vicinity, Luzon Island, Philippines
George Frank Worts
1964, Water Supply Paper 1608-E
In 1961 a reconnaissance of the geology and ground-water hydrology of Poro Point, on the west coast of Luzon Island, Philippines, was made on behalf of the U.S. Department of the Navy. Poro Point, which marks the northern end of Lingayen Gulf, is about half a mile wide and projects...
A magnetic anomaly of possible economic significance in southeastern Minnesota
Isidore Zietz
1964, Circular 489
An aeromagnetic survey in southeastern Minnesota by the U. S. Geological Survey in cooperation with the State of Minnesota has revealed a high-amplitude, linear, and narrow magnetic feature that suggests a possible source of Precambrian iron-formation of economic value. For the past few years the U. S. Geological Survey has...
Ground water east of Jackson Lake, Grand Teton National Park, Wyoming
Laurence J. McGreevy, Ellis D. Gordon
1964, Circular 494
The project area, which lies east of and adjacent to Jackson Lake is on the downthrown eastern block of the Teton fault, a normal fault that trends northward along the west edge of Jackson Lake. Rocks of pre-Cretaceous age are deeply buried beneath this area. Sedimentary rocks of Cretaceous age...
The Water Supply of El Morro National Monument
Samuel Wilson West, Helene Louise Baldwin
1964, Water Supply Paper 1766
In the land of enchantment, between Gallup and Grants, N. Mex., near the Zuni Mountains, a huge sandstone bluff rises abruptly 200 feet above the plain. The Spaniards called it 'El Morro,' which means 'the headland' or 'bluff.' Around it are other mesas and canyons and stands of pinon and...
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...
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...
