Hydrogeology and flow of water in a sand and gravel aquifer contaminated by wood-preserving compounds, Pensacola, Florida
B.J. Franks
1988, Water-Resources Investigations Report 87-4260
The sand and gravel aquifer in southern Escambia County, Florida , is a typical surficial aquifer composed of quartz sands and gravels interbedded locally with silts and clays. Problems of groundwater contamination from leaking surface impoundments are common in surficial aquifers and are a subject of increasing concern and attention....
Discharge ratings for control structures at McHenry Dam on the Fox River, Illinois
G. G. Fisk
1988, Water-Resources Investigations Report 87-4226
Twenty-three measurement of discharge were used to determine discharge ratings for the five adjustable sluice gates, spillway and fish ladder at McHenry Dam on the Fox River in Illinois. Discharge ratings were determined for free weir, free orifice, and submerged orifice flow regimes. Hydraulic conditions that identify flow regimes at...
Sediment sources in the Lake Tahoe Basin, California-Nevada; preliminary results of a four-year study, August 1983-September 1987
B. R. Hill, J.R. Hill, K.M. Nolan
1988, Open-File Report 88-333
Data were collected during a 4-yr study of sediment sources in four drainage basins tributary to Lake Tahoe, California-Nevada. The study areas include the Blackwood, General, Edgewood, and Logan House Creek basins. Data include changes in bank and bed positions at channel cross sections; results of stream-channel mapping; analyses of...
Geologic studies in Alaska by the U.S. Geological Survey during 1987
John P. Galloway, Thomas D. Hamilton, editor(s)
1988, Circular 1016
This volume is a continuation of the annual United States Geological Survey (USGS) Circulars reporting results of work in progress on earth science investigations in Alaska. The series began in 1975 under the title "The United States Geological Survey in Alaska - Accomplishments during 19xx" and has continued since 1986...
The role of sediments in the chemistry of aquatic systems - Proceedings of the sediment chemistry workshop, February 8-12, 1982
Wesley L. Bradford, Arthur J. Horowitz, editor(s)
1988, Circular 969
A workshop on sediment chemistry was held at the U.S. Geological Survey National Headquarters in Reston, Virginia, February 8-12, 1982, to discuss the state of the science and possible future directions for research and operational programs in the Water Resources Division of the U.S. Geological Survey. Technical papers presented broad...
Manmade organic compounds in the surface waters of the United States; a review of current understanding
James A. Smith, P.J. Witkowski, Thomas V. Fusillo
1988, Circular 1007
This report reviews the occurrence and distribution of manmade organic compounds in the surface waters of the United States. On the basis of their aqueous solubilities, nonionic organic compounds partition themselves among water, dissolved organic matter, particulate organic matter, and the lipid reservoirs of aquatic organisms. Ionized organic compounds can...
Climatic data for Williams Lake, Hubbard County, Minnesota, 1986
D.O. Rosenberry, A.M. Sturrock, T. C. Winter
1988, Open-File Report 88-304
Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: water-surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these studies, such as...
