Bedrock topography of northwest Iowa
R.E. Hansen, D. L. Runkle
1986, IMAP 1726
Bedrock in Iowa (Hershey, 1969) generally is overlain by deposits of glacial drive and alluvium. The drift, consisting of glacial till and glacial outwash, ranges in thickness from zero to more than 500 feet in western Iowa; the alluvium in stream valleys ranges in thickness from less than 1 foot...
Hydraulic properties of rock units and chemical quality of water for INEL-1 — A 10,365-foot deep test hole drilled at the Idaho National Engineering Laboratory, Idaho
L. J. Mann
1986, Water-Resources Investigations Report 86-4020
A 10,365-ft deep test hole drilled at the INEL (Idaho National Engineering Laboratory) in southeastern Idaho provided hydraulic information for rock units underlying the Snake River Plain aquifer. Four aquifer tests showed that the hydraulic conductivity decreased with depth--from an average of 0.03 ft/day for the interval from 1,511 to...
Exploration for areas suitable for ground-water development, central Connecticut Valley lowlands, Massachusetts
B. P. Hansen
1986, Water-Resources Investigations Report 84-4106
Drilling and geophysical borehole logs for a 25-sq-mi section of the Connecticut River valley lowlands area of Amherst, Hadley, and Sunderland, Massachusetts, indicate that the area is mostly underlain by fine-grained lacustrine deposits. Nine test wells ranging in depth from 100 to 303 ft completely penetrate the unconsolidated valley fill....

Effect of urban stormwater runoff on ground water beneath recharge basins on Long Island, New York
H. F. Ku, D. L. Simmons
1986, Water-Resources Investigations Report 85-4088
Urban stormwater runoff was monitored during 1980-82 to investigate the source, type, quantity, and fate of contaminants routed to the more than 3,000 recharge basins on Long Island and to determine whether this runoff might be a significant source of contamination to the groundwater reservoir. Forty-six storms were monitored at...
Rock riprap design for protection of stream channels near highway structures; Volume 2, Evaluation of Riprap design procedures
J. C. Blodgett, C.E. McConaughy
1986, Water-Resources Investigations Report 86-4128
In volume 2, seven procedures now being used for design of rock riprap installations were evaluated using data from 26 field sites. Four basic types of riprap failures were identified: Particle erosion, translational slide, modified slump, and slump. Factors associated with riprap failure include stone size , bank side slope,...
Seismicity map of the state of Arizona

1986, Miscellaneous Field Studies Map 1852
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Arizona, even though earthquakes...
Water resources data, Arizona water year 1983
Natalie D. White, W. B. Garrett
1986, Water Data Report AZ-83-1
Water resources data for the 1983 water year for Arizona consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; measurements of ground-water levels; and quality of water from selected wells. Also included are discharge data for crest-stage partial-record stations...

Water levels in major artesian aquifers of the New Jersey Coastal Plain, 1983
J.A. Eckel, R.L. Walker
1986, Water-Resources Investigations Report 86-4028
Water levels and changes in water levels in the major aquifers of the New Jersey Coastal Plain are documented. Water levels in 1,071 wells were measured in 1983, and are compared with 827 water level measurements made in the same wells in 1978. Increased groundwater withdrawals from the major artesian...

Principles of logic and the use of digital geographic information systems
Charles Joseph Robinove
1986, Circular 977
Digital geographic information systems allow many different types of data to be spatially and statistically analyzed. Logical operations can be performed on individual or multiple data planes by algorithms that can be implemented in computer systems. Users and creators of the systems should fully understand these operations. This paper describes...

The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine their mineral values, if any, that may be present. Results must be made available to the public...
