Installation and service manual for the U.S. Geological Survey manometers
James D. Craig
1983, Techniques of Water-Resources Investigations 08-A2
The purpose of this manual is to describe the installation, operation, and maintenance of the bubble-gage manometers currently (1982) used by the U.S. Geological Survey. Other applications of these devices, such as the long manometer and differential manometer, are discussed, and accessories available for them are described. The bubble gage (water-stage...
Computation of continuous records of streamflow
E.J. Kennedy
1983, Techniques of Water-Resources Investigations 03-A13
Records of continuous streamflow, published in the U.S. Geological Survey annual Water Data Reports for the States and territories, are computed from field data, mainly discharge measurements and recorder charts or tapes. This manual describes the computation procedures used and some details of related field operations. It was compiled mostly...
Use of flumes in measuring discharge
F. A. Kilpatrick, V.R. Schneider
1983, Techniques of Water-Resources Investigations 03-A14
Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes. In this chapter, the underlying design principles for each group are discussed; the most commonly used flumes are described and their discharge ratings presented. There is also discussion of considerations in choosing and fitting the appropriate...
Selected hydrologic data, Kolob-Alton-Kaiparowits coal-fields area, south-central Utah
Gerald G. Plantz
1983, Open-File Report 83-871
The Kolob-Alton-Kaiparowits coal-field area (pi. 1) includes about 4,500 square miles in parts of the Colorado River Basin and the Great Basin. The area varies in altitude from less than 4,000 to more than 10,000 feet, and is comprised chiefly of plateaus, benches, and terraces that are dissected by deep,...
Comparison of abundances of chemical elements in mineralized and unmineralized sandstone of the Brushy Basin Member of the Morrison Formation, Smith Lake District, Grants uranium region, New Mexico
C. T. Pierson, C.S. Spirakis, J. F. Robertson
1983, Open-File Report 83-818
Statistical treatment of analytical data from the Mariano Lake and Ruby uranium deposits in the Smith Lake district, New Mexico, indicates that organic carbon, arsenic, barium, calcium, cobalt, copper, gallium, iron, lead, manganese, molybdenum, nickel, selenium, strontium, sulfur, vanadium, yttrium, and zirconium are concentrated along with uranium in primary ore....
The effects of water content and water resistivity on the dispersion of resistivity and dielectric constant in quartz sand in the frequency range 10^2 to 10^8 Hz
W.R. Eberle
1983, Open-File Report 83-914
Using modifications of previously developed methods, measurements were made of the resistivity and the dielectric constant of two similar quartz sands of different porosity over the frequency range 102-108 Hertz for various water contents and water resistivities. Dispersion is pronounced in all the resistivity data above 106 Hz. As water...
Paleomagnetic results from seven middle Paleozoic plutons in the Appalachian Piedmont of North and South Carolina
J.T. Hagstrum
1983, Open-File Report 83-916
Seven isotopically dated plutons of similar middle Paleozoic age (approx. 400 Ma) were sampled for paleomagnetic study. The results from 12 sites (152 samples) within these plutons show two types of remanence behavior that appear fairly consistent with rock composition. The more leucocratic rocks (9 sites) tend to yield single-component...
Forward and inverse cartographic projection procedures
G. I. Evenden
1983, Open-File Report 83-625
A set of procedures for performing 19 common cartographic transformations between geographic and artesian coordinate systems are presented along with instruction for usage, installation and testing results. These procedures are written in the RATFOR preprocessor language and effort was made to ensure transportability of the code as well as consistency...
The environmental history and present condition of Saudi Arabia's northern sand seas
John W. Whitney, D.J. Faulkender, Meyer Rubin
1983, Open-File Report 83-749
Saudi Arabia's northern sand seas are composed dominantly of stable dune systems, even though the modern climate is arid. The stable dunes are large and support a sparse semidesert vegetation. Active dunes are small and commonly confined to the crests of stable dunes; they comprise less than 5 percent of...
