Traveltime and longitudinal dispersion in Illinois streams
J.B. Graf
1984, Open-File Report 84-468
Twenty-seven measurements of traveltime and longitudinal dispersion in 10 Illinois streams provide data needed for estimating traveltime of peak concentration of a conservative solute, traveltime of the leading edge of a solute cloud, peak concentration resulting from a given quantity of solute, and passage time of solute past a given...
Ground-water resources of Audrain County, Missouri
L. F. Emmett, J. L. Imes
1984, Open-File Report 84-245
The deep (principal) aquifer in Audrain County has an average thickness of about 1,300 feet and is composed of dolomite and minor quantities of sandstone of Cambrian and Ordovician age. The deep aquifer is the source of water for all public-supply and irrigation wells in Audrain County. Pumpage from the...
Preconstruction and simulated postconstruction ground-water levels at urban centers in the Red River Navigation Project area, Louisiana
J.E. Rogers
1984, Water-Resources Investigations Report 83-4154
The Red River Valley in Louisiana is 3 to 10 miles wide and is underlain by the Red River alluvial aquifer. This aquifer is in hydraulic connection with the Red River. Precipitation infiltrates the aquifer and water discharges from the aquifer at the Red River and major tributaries. Construction of...
Chemical quality of the Saw Mill River, Westchester County, New York, 1981-83
R.J. Rogers
1984, Water-Resources Investigations Report 84-4225
Surface waters, bottom sediments and coatings formed on artificial substrates (ceramic tiles) were analyzed to evaluate the chemical quality of the Saw Mill River, New York. Heavy metals, nutrients, and organic contaminants were studied. Dissolved orthophosphate concentrations were highest in the lower third of the river. Dissolved manganese was the...
Description and hydrogeologic implications of cored sedimentary material from the 1975 drilling program at the radioactive waste management complex, Idaho
C.T. Rightmire
1984, Water-Resources Investigations Report 84-4071
Samples of sedimentary material from interbeds between basalt flows and from fractures in the flows, taken from two drill cores at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory were analyzed for (1) particle-size dribution, (2) bulk mineralogy, (3) clay mineralogy, (4) cation-exchange capacity, and (5) carbonate...
Annual summary of ground-water conditions in Arizona, spring 1982 to spring 1983
Water Resources Division, U.S. Geological Survey
1984, Open-File Report 84-428
The withdrawal of ground water was slightly less than 4.2 million acre-feet in Arizona in 1982, which is about 1.2 million acre-feet less than the amount withdrawn in 1981. Most of the decrease in 1982 was in the amount of ground water used for irrigation in the Basin and Range...
Climatic data for Mirror Lake, West Thornton, New Hampshire, 1981-82
A.M. Sturrock, D.C. Buso, G.M. Bieber, L.G. Engelbrecht, T. C. Winter
1984, Open-File Report 84-816
Research on the hydrology of Mirror Lake, (north-central) New Hampshire includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: temperature of lake water surface, dry-bulb and wet-bulb air temperatures, wind speed, precipitation and solar radiation. Data are collected at raft and land...
The hydrogeologic framework for the southeastern Coastal Plain aquifer system of the United States
R.A. Renken
1984, Water-Resources Investigations Report 84-4243
Tertiary and Cretaceous age sand aquifers of the southeastern United States Coastal Plain constitute a distinct multistate hydrogeologic regime informally defined as the southeastern sand aquifer. Seven regional hydrogeologic units are defined; four regional aquifer units and three regional confining beds. Sand aquifers of this system consist of quartzose, feldspathic,...
