Hydrology and sedimentation of Bixler Run Basin, central Pennsylvania
Lloyd A. Reed
1976, Water Supply Paper 1798-N
Rainfall, streamflow, stream chemical, and sediment discharge data were collected from Bixler Run near Loysville, Pa., during the period from February 1954 to September 1969 as part of a project to evaluate sediment discharge from an agricultural area in which soil-conservation techniques were being adopted at a moderate rate. The...
Mineral deposits and occurrences in the McCarthy Quadrangle, Alaska
E.M. MacKevett Jr.
1976, Miscellaneous Field Studies Map 773-B
The McCarthy quadrangle contains numerous and diverse mineral deposits in various geologic settings. Copper is the dominant mineral commodity, both historically and in terms of potential future production. Gold and silver are the only other metals that have been produced. The metalliferous deposits are concentrated in a northwest-trending belt along...
Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina
Clyde E. Simmons
1976, Water Supply Paper 1798-O
The sediment-transport characteristics of streams were determined in a 15,500-square-kilometre (6,000-square-mile) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations in parts of 4 major river basins?the Roanoke, Pamlico,...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: November 1976
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1976, Open-File Report 76-300-K
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Stability of highwalls in surface coal mines, western Powder Ridge Basin, Wyoming and Montana
Fitzhugh T. Lee, William K. Smith, William Z. Savage
1976, Open-File Report 76-846
Preliminary results from the first part of a two-part investigation of the stability of highwalls in open-pit coal mines in the Fort Union Formation of the western Powder River Basin of Wyoming and Montana indicate that these highwalls are subject to time-dependent deformation. Field investigations and laboratory physical-properties tests of...
Finite difference model for aquifer simulation in two dimensions with results of numerical experiments
Peter C. Trescott, George Francis Pinder, S. P. Larson
1976, Techniques of Water-Resources Investigations 07-C1
The model will simulate ground-water flow in an artesian aquifer, a water-table aquifer, or a combined artesian and water-table aquifer. The aquifer may be heterogeneous and anisotropic and have irregular boundaries. The source term in the flow equation may include well discharge, constant recharge, leakage from confining beds in which...
Identification codes for organizations listed in computerized data systems of the U.S. Geological Survey
Melvin D. Edwards, Margery O. Drilleau
1976, Open-File Report 76-855
This report contains codes for the identification of public and private organizations listed in computerized data systems. These codes are used by the U.S. Geological Survey 's National Water Data Exchange (NAWDEX), National Water Data Storage and Retrieval System (WATSTORE), and National Cartographic Information Center (NCIC). The format structure of...
Use of an airborne Fraunhofer line discriminator for the detection of solar stimulated luminescence
Robert D. Watson, William R. Hemphill
1976, Open-File Report 76-202
Luminescence is the property of some materials to emit light when excited by external stimuli such as ultraviolet or visible light or by chemical or mechanical action. The Fraunhofer line discriminator (FLO) is an airborne electro-optical device which operates as a non-imaging radiometer and permits detection of solar stimulated luminescence...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: December 1976
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1976, Open-File Report 76-300-L
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Water-quality data for the Southern Ute Indian Reservation, southwestern Colorado
E. Carter Hutchinson, Robert E. Brogden
1976, Open-File Report 76-16
Water-quality data from a study by the U.S. Geological Survey on the Southern Ute Indian Reservation in southwestern Colorado are presented in two tables. The data were collected during 1973-76 from 338 ground-water and surface-water samples. All samples were analyzed for major catons and anions, and selenium and arsenic. Data...
Water resources of the Warm Springs Indian Reservation, Oregon
J. H. Robison, Antonius Laenen
1976, Water-Resources Investigations Report 76-26
Water-resources data for the 1,000-square-mile Warm Springs Indian Reservation in north-central Oregon were obtained and evaluated. The area is bounded on the west by the crest of the Cascade Range and on the south and east by the Metolius and Deschutes Rivers. The mountainous western part is underlain by young...
