Application of digital mapping technology to the display of hydrologic information; a proof-of-concept test in the Fox-Wolf River Basin, Wisconsin
G. K. Moore, L.G. Baten, G.J. Allord, C.J. Robinove
1983, Water-Resources Investigations Report 83-4142
The Fox-Wolf River basin in east-central Wisconsin was selected to test concepts for a water-resources information system using digital mapping technology. This basin of 16,800 sq km is typical of many areas in the country. Fifty digital data sets were included in the Fox-Wolf information system. Many data sets were...
Map showing outcrops of basaltic rocks of early Quaternary and Tertiary age, Basin and Range province, Southern California
Kurt Roggensack, David A. Lopez
1983, Water-Resources Investigations Report 83-4116-G
This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain detailed information on subjects that characterize the geohydrology of the province, including the ground-water hydrology/ ground-water...
Guide to North Dakota's ground-water resources
Q.F. Paulson
1983, Water Supply Paper 2236
Ground water, the water we pump from the Earth through wells or that which flows naturally from springs, is one of North Dakota's most valuable resources. More than 60 percent of the people living in the State use ground water for one purpose of another. It is the only source...
Ground water in carbonate rocks and regolith in the Fairview area, Tennessee
C.R. Burchett, Ann Zurawski, A.K. Sparkes, E. F. Hollyday
1983, Water-Resources Investigations Report 83-4134
Fourteen test wells drilled in the Fairview area, Tennessee, produce from 3 to 100 gallons per minute and have an average yield of 32 gallons per minute, measured while blowing water from the wells with compressed air. In comparison, the average yield of supply wells reported by drillers is 13...
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...
Geology and resources of the Andersonville, Georgia, kaolin and bauxite district
Harland E. Cofer, John Phillip Manker
1983, Open-File Report 83-580
The kaolin and kaolin-rich sediments of the Andersonville district were deposited in an estuary environment with restricted circulation and little tidal or longshore current influence. Micaceous kaolinitic clays were deposited during late Paleocene time on broad, shallow water flats between deeper water distributary channels in the estuarine system. During the...
Maps showing selected geology and phosphate resources of the Upper Valley quadrangle, Caribou County, Idaho
Pamela Dunlap Derkey, Pamela Palmer, Nancy J. Wotruba
1983, Mineral Investigations Resource Map 71
This report summarizes information on the thickness, grade, lateral continuity, phosphate resources, and ownership of phosphate-bearing units in the Meade Peak Phosphatic Shale Member of the Phosphoria Formation in the Upper Valley quadrangle. This report is one of a series of quadrangle reports prepared by the Idaho Bureau of Mines...
Application of total-count aeroradiometric maps to the exploration for heavy-mineral deposits in the coastal plain of Virginia, with a section on field-spectrometer-data reduction
A. E. Grosz, Kenneth L. Kosanke
1983, Professional Paper 1263
Total-count contoured aeroradiometric maps for the Coastal Plain of Virginia were used in an effort to locate economic heavy-mineral placer deposits. The principle behind this approach is that heavy- mineral suites commonly contain radioactive minerals that, if the concentration of heavy minerals is exposed at or within inches of the...
Nonparametric tests for trends in water-quality data using the statistical analysis system
Charles G. Crawford, James R. Slack, Robert M. Hirsch
1983, Open-File Report 83-550
Two nonparametric procedures to test for trends in water-quality data (SEASKEN AND SEASRS) have been developed for the Statistical Analysis System* (SAS). The procedure SEASKEN tests for a monotonic trend in time by a modified form of Kendall's tau, the Seasonal Kendall test. The procedure SEASRS tests for a step...
Geological and operational summary, Norton Sound COST No. 1 well, Norton Sound, Alaska
Ronald F. Turner, J.G. Bolm, C.M. McCarthy, D. A. Steffy, Paul Lowry, T.O. Flett
1983, Open-File Report 83-124
Title 30, Code of Federal Regulations (CFR), paragraph 251.14 stipulates that geological data and processed geological information obtained from Deep Stratigraphic Test wells drilled on the Outer Continental Shelf (OCS) be made available for public inspection 60 calendar days after the issuance of the first Federal lease within 50 nautical...
Evaluation of water levels in major aquifers of the New Jersey coastal plain, 1978
R.L. Walker
1983, Water-Resources Investigations Report 82-4077
Increased withdrawals from the major artesian aquifers that underlie the New Jersey Coastal Plain have caused water-level declines and large regional cones of depression. These cones of depression are delineated on detailed potentiometric surface maps produced from water-level data collected in the field in 1978. Water levels for 1978 are...
