Aquifer-nomenclature guidelines
R. L. Laney, C.B. Davidson
1986, Open-File Report 86-534
Guidelines and recommendations for naming aquifers are presented to assist authors of geohydrological reports in the United States Geological Survey, Water Resources Division. The hierarchy of terms that is used for water- yielding rocks from largest to smallest is aquifer system, aquifer, and zone. If aquifers are named, the names...
Aquifer model of the Susquehanna River valley in southwestern Broome County, New York
Allan D. Randall
1986, Water-Resources Investigations Report 85-4099
A finite-difference model of ground-water flow within stratified drift in the 14-mile reach of the Susquehanna River valley from Binghamton west to the Tioga County line (including Johnson City, Endicott, and Vestal) has been developed. Outwash is the most permeable and extensive type of stratified drift in the valley but...
Sediment transport characteristics of selected streams in the Susitna River Basin, Alaska, October 1983 to September 1984
J. M. Knott, Stephen W. Lipscomb, Terry W. Lewis
1986, Open-File Report 86-424-W
The upper reaches of the Susitna River have been considered for development of a large power generation system for south-central Alaska. This report presents a summary and discussion of sediment and hydraulic data obtained from October 1983 to September 1984 at ten sites on the Susitna, Chulitna, Talkeetna, and Yentna...
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...
Direction of ground-water flow and ground-water quality near a landfill in Falmouth, Massachusetts
J.H. Persky
1986, Water-Resources Investigations Report 85-4188
A landfill in Falmouth, Massachusetts, is upgradient of a pond used for municipal water supply, but analysis of groundwater flow directions and groundwater quality indicates that leachate from the landfill does not threaten the municipal water supply. A network of water table observation wells was established, and water table altitudes...
Selenium concentrations in leaf material from Astragalus Oxyphysus (diablo locoweed) and Atriplex Lentiformis (quail bush) in the interior Coast Ranges and the western San Joaquin Valley, California
J. A. Izbicki, T. F. Harms
1986, Water-Resources Investigations Report 86-4066
Leaf material from selenium accumulating plants was collected and analyzed for selenium to obtain a relative indication of selenium concentrations in soils and identify sites suitable for further soil study. Selenium concentrations of 14 samples of leaf material from Astragalus oxyphysus ranged from 0.08 to 3.5 microg/g dry weight and...
Discharge ratings for control gates at Mississippi River Lock and Dam 16, Muscatine, Iowa
Albert J. Heinitz
1986, Water-Resources Investigations Report 86-4136
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the lock and dams. Discharge ratings for the gates on Lock and Dam 16, at Muscatine, Iowa, were developed from current-meter discharge measurements made in the forebays of...
The relation of ground-water quality to housing density, Cape Cod, Massachusetts
J.H. Persky
1986, Water-Resources Investigations Report 86-4093
Correlation of median nitrate concentration in groundwater with housing density for 18 sample areas on Cape Cod yields a Pearson correlation coefficient of 0.802, which is significant at the 95 % confidence level. In five of nine sample areas where housing density is greater than one unit/acre, nitrate concentrations exceed...
Water resources of Yankton County, South Dakota
E. F. Bugliosi
1986, Water-Resources Investigations Report 84-4241
The major surface-water sources in Yankton County, South Dakota are Lewis and Clark Lake, Marindahl and Beaver Lakes, and the Missouri and James Rivers. The James River has an average flow of 375 cu ft/sec and the Missouri River at Yankton has an average flow of 26,410 cu ft/sec. Major...
Comparison of flood frequency estimates from synthetic and observed data on small drainage areas in Mississippi
B.E. Colson
1986, Water-Resources Investigations Report 86-4034
In 1964 the U.S. Geological Survey in Mississippi expanded the small stream gaging network for collection of rainfall and runoff data to 92 stations. To expedite availability of flood frequency information a rainfall-runoff model using available long-term rainfall data was calibrated to synthesize flood peaks. Results obtained from observed annual...
Quality of ground water in the Payette River basin, Idaho
D. J. Parliman
1986, Water-Resources Investigations Report 86-4013
As part of a study to obtain groundwater quality data in areas of Idaho were land- and water-resource development is expected to increase, water quality, geologic, and hydrologic data were collected for 74 wells in the Payette River basin, west-central Idaho, from July to October 1982. Historical (pre-1982) data from...
Organic compounds in ground water near a sanitary landfill in the Town of Brookhaven, Long Island, New York
K.A. Pearsall, E. J. Wexler
1986, Water-Resources Investigations Report 85-4218
Landfill leachate and groundwater near the Brookhaven landfill site were analyzed for volatile, acid-extractable, and base/neutral-extractable organic compounds classified by EPA as ' priority pollutants, ' and for dissolved organic carbon (DOC) and inorganic constituents. Thirteen priority pollutants were detected, including benzene, chlorobenzene, ethyl benzene, and naphthalene. The most commonly...
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...
Estimating magnitude and frequency of floods for Wisconsin urban streams
D.H. Conger
1986, Water-Resources Investigations Report 86-4005
Equations for estimating magnitude and frequency of floods for Wisconsin streams with drainage basins containing various amounts of existing or projected urban development were developed by flood-frequency and multiple-regression analyses. Multiple-regression techniques were used to develop equations for estimating flood frequencies at ungaged urban sites. The flood-frequency equations are based on...

A.J. Heinitz
1986, Open-File Report 86-476
Flood elevation profiles and flood peak discharges for the floods of 1953, 1962, 1973, and 1983 in the Floyd River basin are given in this report. The profiles cover the Floyd and West Branch Floyd Rivers. The 1953 flood is the greatest known on the Floyd River since at least...
