Simulating unsteady transport of nitrogen, biochemical oxygen demand, and dissolved oxygen in the Chattahoochee River downstream from Atlanta, Georgia
Harvey E. Jobson
1985, Water Supply Paper 2264
As part of an intensive water-quality assessment of the Chattahoochee River, repetitive water-quality measurements were made at 12 sites along a 69-kilometer reach of the river downstream of Atlanta, Georgia. Concentrations of seven constituents (temperature, dissolved oxygen, ultimate carbonaceous biochemical oxygen demand (BOD), organic nitrogen, ammonia, nitrite, and nitrate) were...
APSAS; an Automated Particle Size Analysis System
Lawrence J. Poppe, A.H. Eliason, J.J. Fredericks
1985, Circular 963
The Automated Particle Size Analysis System integrates a settling tube and an electroresistance multichannel particle-size analyzer (Coulter Counter) with a Pro-Comp/gg microcomputer and a Hewlett Packard 2100 MX(HP 2100 MX) minicomputer. This system and its associated software digitize the raw sediment grain-size data, combine the coarse- and fine-fraction data into...
Interpretation of geochemical data from panned concentrates of wadi sediments using R-mode factor analysis, Jabal Habashi Quadrangle, sheet 26F, Kingdom of Saudi Arabia
M. S. Allen, R.R. Tidball, R.M. Samater, G.I. Selner
1985, Open-File Report 85-5
Panned-concentrate samples from wadi sediments were collected over terranes of Precambrian age intrusive, volcanic, sedimentary, and metamorphic rocks, within the Jabal Habashi quadrangle, sheet 26F, Kingdom of Saudi Arabia. Multivariate analysis of the chemical data indicates that a significant base-metal association occurs in three areas within the quadrangle. An association...
Effects of artificial recharge on the Ogallala aquifer, Texas
Richmond Flint Brown, W.S. Keys
1985, Water Supply Paper 2251
Four recharge tests were conducted by injecting water from playa lakes through wells into the Ogallala Formation. Injection was by gravity flow and by pumping under pressure. At one site, 34-acre feet of water was injected by gravity and produced a significant increase in yield of the well. At a...
Development and testing of highway storm-sewer flow measurement and recording system
F. A. Kilpatrick, W.R. Kaehrle, Jack Hardee, E. H. Cordes, M. N. Landers
1985, Water-Resources Investigations Report 85-4111
A comprehensive study and development of measuring instruments and techniques for measuring all components of flow in a storm-sewer drainage system was undertaken by the U.S. Geological Survey under the sponsorship of the Federal Highway Administration. The study involved laboratory and field calibration and testing of measuring flumes, pipe insert...
Water quality and streamflow data for the West Fork Trinity River in Fort Worth, Texas
S. C. McCutcheon
1985, Water-Resources Investigations Report 84-4330
Water-quality data were collected on a 13.6-mile reach of the West Fork Trinity River in Fort Worth, Texas to test a dynamic Lagrangian model. Flow was steady. Loads of dissolved constituents varied with time at the beginning of the study reach and in the reach, primarily because of photosynthesis. River...
Hydrologic effects of ground- and surface-water withdrawals in the Milford area, Elkhart and Kosciusko counties, Indiana
H.A. Lindgren, J. G. Peters, D.A. Cohen, E. J. Crompton
1985, Water-Resources Investigations Report 85-4166
Agricultural irrigation in northern Indiana has increased rapidly since 1975 and might double by the year 2000. A 16.5 square-mile area in north-central Indiana was studied to determine possible effects of increased irrigation on local water supply. In 1982, an average of 2 inches of water was used to irrigate...
Description of water-systems operations in the Arkansas River basin, Colorado
P.O. Abbott
1985, Water-Resources Investigations Report 85-4092
To facilitate a current project modeling the hydrology of the Arkansas River basin in Colorado, a description of the regulation of water in the basin is necessary. The geographic and climatic setting of the Arkansas River basin that necessitates the use, reuse, importation, and storage of water are discussed. The...
Geohydrology of rocks penetrated by test well USW H-4, Yucca Mountain, Nye County, Nevada
M.S. Whitfield, E.P. Eshom, William Thordarson, D. H. Schaefer
1985, Water-Resources Investigations Report 85-4030
Test well USW H-4 is one of several wells drilled in the southwestern part of the Nevada Test Site for hydraulic testing, hydrologic monitoring, and geophysical logging. The work was performed in cooperation with the U.S. Department of Energy. The rocks penetrated by the well to a total depth of...
Water-resources appraisal of the Camp Swift lignite area, central Texas
J.L. Gaylord, R.M. Slade, L.M. Ruiz, C.T. Welborn, E.T. Baker
1985, Water-Resources Investigations Report 84-4333
The Camp Swift lignite area was studied to describe the hydrogeology and to provide baseline data of the ground-water and surface-water resources that could be affected by the strip mining of lignite. The investigation was centered on the 18-square mile Camp Swift Military Reservation where a reported 80 to 100...

1985, Water Data Report MO-84-1
Water resources data for the 1984 water year for Missouri consist of records of stage, discharge, and water quality of lakes and reservoirs; contains records for water discharge at 112 gaging stations; stage and contents at 9 lakes and reservoirs; water quality at 71 sampling stations (including 1 lake) and...
Geologic characteristics of sediment- and volcanic-hosted disseminated gold deposits - Search for an occurrence model
Donald E. White, Robert O. Fournier, James J. Rytuba, Robert O. Rye, Charles G. Cunningham, Byron R. Berger, Miles L. Silberman, Harold F. Bonham Jr., Donald G. Strachan, Donald J. Birak, Robert J. Hawkins, Edwin W. Tooker
Edwin W. Tooker, editor(s)
1985, Bulletin 1646
The current expansion of resource information, particularly on "disseminated" gold, and the improved technologies now available for resource investigations should place us in an enhanced position for developing a better predictive methodology for meeting one of the important responsibilities of the U.S. Geological Survey-to examine and assess the mineral resources...
