Hydrogeology and leachate movement near two chemical-waste sites in Oswego County, New York
H. R. Anderson, Todd S. Miller
1986, Water-Resources Investigations Report 84-4148
Forty-five observation wells and test holes were installed at two chemical waste disposal sites in Oswego County, New York, to evaluate the hydrogeologic conditions and the rate and direction of leachate migration. At the site near Oswego groundwater moves northward at an average velocity of 0.4 ft/day through unconsolidated glacial...
Ground-water resources in Mendocino County, California
C. D. Farrar
1986, Water-Resources Investigations Report 85-4258
Mendocino County includes about 3,500 sq mi of coastal northern California. Groundwater is the main source for municipal and individual domestic water systems and contributes significantly to irrigation. Consolidated rocks of the Franciscan Complex are exposed over most of the county. The consolidated rocks are commonly dry and generally supply...

Habitat Suitability Index Models: Brown thrasher
Brian S. Cade
1986, FWS/OBS 82/10.118
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the brown thrasher (Toxostoma rufum). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Potentiometric map of the Cockfield Aquifer in Mississippi, fall 1984
Daphne Darden
1986, Water-Resources Investigations Report 86-4042
This map, the second in a series for the Cockfield aquifer in Mississippi, follows a map that delineated the 1980 potentiometric surface of the aquifer. This water level map is based on water level measurements made in about 80 wells in the Cockfield aquifer in the fall of 1984. The...
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...
Pilot study for collection of bridge-scour data
R.D. Jarrett, J. M. Boyle
1986, Water-Resources Investigations Report 86-4030
Scour around bridges is a serious problem on many rivers; bridge failure often is attributed to undermining of piers or abutments by scour. A pilot study was made at four bridge sites in Colorado to develop and test guidelines for collecting scour data onsite during high flows. These guidelines potentially...

Effects of surface coal mining on suspended-sediment discharge in a small mountain watershed, Fayette County, Pennsylvania
T.M. Mastrilli, D.E. Stump
1986, Water-Resources Investigations Report 85-4093
Data collected in the upper Stony Fork basin from July 1980 to November 1981 indicate that logging operations associated with block-cut surface mining temporarily increased suspended-sediment discharge of Stony Fork. However, the strip-mining operation did not increase the suspended sediment discharges of Stony Fork because of effective sediment-control measures. These...

Three-dimensional model simulation of steady-state ground-water flow in the Albuquerque-Belen Basin, New Mexico
J. M. Kernodle, W. B. Scott
1986, Water-Resources Investigations Report 84-4353
As part of the Southwest Alluvial Basins study, model was constructed to simulate the alluvial aquifer system underlying the Albuquerque-Belen Basin. The model was used to simulate the steady-state flow condition assumed to have existed prior to 1960. Until this time there apparently were no long-term groundwater level changes of...
