Microcumpter computation of water quality discharges
Dennis R. Helsel
1983, Open-File Report 82-901
A fully prompted program (SEDQ) has been developed to calculate daily and instantaneous water quality (QW) discharges. It is written in a version of BASIC, and requires inputs of gage heights, discharge rating curve, shifts, and water quality concentration information. Concentration plots may be modified interactively using the display screen....
Geothermal resources of the western arm of the Black Rock Desert, northwestern Nevada: Part I, geology and geophysics
Donald H. Schaefer, Alan H. Welch, Douglas K. Mauzer
1983, Open-File Report 81-918
Studies of the geothermal potential of the western arm of the Black Rock Desert in northwestern Nevada included a compilation of existing geologic data on a detailed map, a temperature survey at 1-meter depth, a thermal-scanner survey, and gravity and seismic surveys to determine basin geometry. The temperature survey showed...
Water-resources investigations of the U.S. Geological Survey in the Souris-Red Rivers basin in Minnesota, North Dakota, and South Dakota
J. E. Heisel
1983, Open-File Report 83-218
Information obtained on water resources by Federal and State agencies in the Souris-Red Rivers basin along the Canadian border in the midwestern United States is available for analysis to address flood, drought, and supply problems. It consists of streamflows, ground water measurements, and quality of water determinations. This summary contains...
A statistical summary of data from the U.S. Geological Survey's national water quality networks
R. A. Smith, R. B. Alexander
1983, Open-File Report 83-533
The U.S. Geological Survey Operates two nationwide networks to monitor water quality, the National Hydrologic Bench-Mark Network and the National Stream Quality Accounting Network (NASQAN). The Bench-Mark network is composed of 51 stations in small drainage basins which are as close as possible to their natural state, with no human...
Hornblende-rich, high grade metamorphic terranes in the southernmost Sierra Nevada, California, and implications for crustal depths and batholith roots
Donald Clarence Ross
1983, Open-File Report 83-465
The southernmost Sierra Nevaaa widely exposes hornblende-rich, gneissic to granoblastic, amphibolite- to granulite-grade, metamorphic rocks and associated magmatic rocks, all of mid-Cretaceous age. Locally, red garnet, in part in euhedral crystals as large as 10 cm, as well as strongly pleochroic hyperstnene, characterize these rocks. These hornblende-rich rocks dominate the...
Flood characteristics of urban watersheds in the United States
Vernon B. Sauer, W.O. Thomas Jr., V.A. Stricker, K. V. Wilson
1983, Water Supply Paper 2207
A nationwide study of flood magnitude and frequency in urban areas was made for the purpose of reviewing available literature, compiling an urban flood data base, and developing methods of estimating urban floodflow characteristics in ungaged areas. The literature review contains synopses of 128 recent publications related to urban floodflow....
Petrographic (thin section) notes on selected samples from hornblende-rich metamorphic terranes in the southernmost Sierra Nevada, California
Donald Clarence Ross
1983, Open-File Report 83-587
Medium- to high-grade metamorphic rocks that are commonly hornblende-rich, and probably largely of 'oceanic' affinity, are widespread in the southernmost Sierra Nevada, California. These metamorphic rocks are largely amphibolite, mafic and felsic gneiss, granofels, and hypersthene granulite The mineral assemblages suggest that these rocks are at least in part of...
Quaternary geologic map of the Chicago 4 degrees x 6 degrees quadrangle, United States
Ned K. Bleuer, David M. Mickelson, William R. Farrand, Richard P. Goldthwait, David S. Fullerton
Gerald M. Richmond, editor(s)
1983, IMAP 1420(NK-16)
The Quaternary Geologic Map of the Chicago 4 degree x 6 degree Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during...
Computer-generated mineral commodity deposit maps
Paul G. Schruben, J. Thomas Hanley
1983, Open-File Report 83-410
This report describes an automated method of generating deposit maps of mineral commodity information. In addition, it serves as a user's manual for the authors' mapping system. Procedures were developed which allow commodity specialists to enter deposit information, retrieve selected data, and plot deposit symbols in any geographic area within...
Geothermal resources of southern Idaho
Don R. Mabey
1983, Circular 866
The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150?C. Water from many of these systems is valuable for direct heat applications, but is lower than...
