Low-flow characteristics of Wisconsin streams at sewage-treatment plants
W.A. Gebert, B. K. Holmstrom
1974, Water-Resources Investigations Report 74-45
Low-flow characteristics of Wisconsin streams at 415 sewage -treatment plants are presented in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow that occurs on the average of once in 2 years (Q7, 2) and the annual minimum 7 -day mean flow that occurs on the...
Application of surface geophysics to ground-water investigations
Adel A. R. Zohdy, Gordon P. Eaton, Don R. Mabey
1974, Techniques of Water-Resources Investigations 02-D1
This manual reviews the standard methods of surface geophysics applicable to ground-water investigations. It covers electrical methods, seismic and gravity methods, and magnetic methods. The general physical principles underlying each method and its capabilities and limitations are described. Possibilities for non-uniqueness of interpretation of geophysical results are...
Population ecology of the mallard: II. Breeding habitat conditions, size of the breeding populations, and production indices
Richard S. Pospahala, David R. Anderson, Charles J. Henny
1974, Resource Publication 115
This report, the second in a series on a comprehensive analysis of mallard population data, provides information on mallard breeding habitat, the size and distribution of breeding populations, and indices to production. The information in this report is primarily the result of large-scale aerial surveys conducted during May and July,...
Optical data processing and projected applications of the ERTS-1 imagery covering the 1973 Mississippi River Valley floods
Morris Deutsch, Fred Ruggles
1974, Water Resources Bulletin (10) 1023-1039
Flooding along the Mississippi River and some of its tributaries was detected by the multispectral scanner (MSS) on the Earth Resources Technology Satellite (ERTS-1) on at least three orbits during the spring of 1973. The ERTS data provided the first opportunity for mapping the regional extent of flooding at the...
Survey of remote sensing applications
Morris Deutsch
1974, Water Well Journal (28) 35-38
Data from the first earth resources technology satellite (ERTS) as well as from NASA and other aircraft, contain much of the information indicative of the distribution of groundwater and the extent of its utilization. Thermal infrared imagery from aircraft is particularly valuable in studying groundwater discharge to the sea and...
EROS: A space program for Earth resources
Water Resources Division, U.S. Geological Survey
1974, Report
The EROS Program, administered by the U. S. Geological Survey, works with representatives of departmental bureaus and offices to coordinate research and application of remote-sensing technology to the day to-day operations of the department. Most of the research and applications have been made possible by the experimental data acquisition systems...
Strain-gage measurements in Carlsbad Caverns, New Mexico
J. S. McLean
1974, Journal of Research of the U.S. Geological Survey (3) 281-283
Displacement transducers installed on a near-vertical joint in the lunchroom in Carlsbad Caverns measured small movements along the joint with a resolution of 3.7X 10-6 in (9.4X10-6 cm). During 1973 the maximum annual displacement horizontally, vertically, and perpendicularly to the plane of the joint was 4.7X10-4, 4.0X10-4, and 1.1X10-4 in...
Preliminary findings of a leachate study on two landfills in Suffolk County, New York
Grant E. Kimmel, Olin C. Braids
1974, Journal of Research of the U.S. Geological Survey (3) 273-280
Plumes of leachate-enriched ground water extend 10,600 and 5,000 ft (3,200 and 1,500 m) downgradient from landfills in the towns of Babylon and Islip, respectively, and extend vertically beneath the landfills to the base of the upper glacial aquifer, whose thickness ranges from 71 to 77 ft (22-24 m) at...
Upward migration of deep-well waste injection fluids in Floridan Aquifer, south Florida
M. I. Kaufman, D.J. McKenzie
1974, Journal of Research of the U.S. Geological Survey (3) 261-271
Geochemical data from an industrial deep-well waste injection system southeast of Lake Okeechobee indicate a decrease in sulfate concentration concomitant with an increase in hydrogen sulfide concentration, a result of oxidation of injected organic waste by anaerobic bacteria. Subtle decreases in the sulfate-chloride ratio suggest that the waste migrated upward...
Geometry and growth of the White Sands dune field, New Mexico
Edwin D. McKee, Richard J. Moiola
1974, Journal of Research of the U.S. Geological Survey (3) 59-66
Recent studies of the cores from four drill holes at the White Sands dune field in New Mexico demonstrated that the eolian sand body below the present active dunes ranges in thickness from 23 to 34 ft in the area tested. It consists of one to two older generations of...
Stratigraphic relationships within the Baraga Group of Precambrian age, central Upper Peninsula, Michigan
W.F. Cannon, John S. Klasner
1974, Journal of Research of the U.S. Geological Survey (3) 47-51
Details of the stratigraphic section in parts of northern Michigan have been known for many years, but correlation of units between geographically separated areas has been partly speculative. Mapping in the Witch Lake quadrangle has filled the gap between well-studied areas of the Marquette trough and parts of Iron and...
