Space, time, and the third dimension (model error)
Marshall E. Moss
1979, Water Resources Research (15) 1797-1800
The space-time tradeoff of hydrologic data collection (the ability to substitute spatial coverage for temporal extension of records or vice versa) is controlled jointly by the statistical properties of the phenomena that are being measured and by the model that is used to meld the information sources. The control exerted...
The flow mechanism in the Chalk based on radio-isotope analyses of groundwater in the London Basin
R.A. Downing, F.J. Pearson, D. B. Smith
1979, Journal of Hydrology (40) 67-83
14C analyses of groundwaters from the Chalk of the London Basin are re-interpreted and the age of the groundwater is revised. Radio-isotope analyses are used to examine the flow mechanism in the aquifer. The evidence supports the view that a network of micro-fissures and larger intergranular pores in the matrix...
Uranium transport in the Walker River Basin, California and Nevada
L. V. Benson, D. L. Leach
1979, Journal of Geochemical Exploration (11) 227-248
During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within...
Fall foods of migrant common snipe in North Dakota
E.K. Fritzell, G.A. Swanson, M.I. Meyer
1979, Journal of Wildlife Management (43) 253-257
Studies of foods consumed by common snipe (Capella gallinago) during fall migration (Sperry 1940, Erickson 1941, Choate in Tuck 1972, Tuck 1972) have shown that diets vary among habitats. More recently, Fogarty and Arnold (1977) expressed the need for more detailed information on snipe food habits and more refined knowledge...
Disequilibrium in the 238uranium series in samples from Yeelirrie, Western Australia
R.S. Lively, R.S. Harmon, A. A. Levinson, C.J. Bland
1979, Journal of Geochemical Exploration (12) 57-65
Uranium-series disequilibrium studies carried out on samples from the Yeelirrie uranium deposit, Western Australia, indicate that uranium and radium have been migrating within the deposit during recent times, and are actually being removed from the deposit. Samples collected for 230Th/234U age dating were found to be substantially out of equilibrium,...
Major geochemical processes in the evolution of carbonate-Aquifer systems
B.B. Hanshaw, W. Back
1979, Journal of Hydrology (43) 287-312
As a result of recent advances by carbonate petrologists and geochemists, hydrologists are provided with new insights into the origin and explanation of many aquifer characteristics and hydrologic phenomena. Some major advances include the recognition that: (1) most carbonate sediments are of biological origin; (2) they have a strong bimodal...
Geochemical and hydrologic considerations and the use of enthalpy-chloride diagrams in the prediction of underground conditions in hot-spring systems
R.O. Fournier
1979, Journal of Volcanology and Geothermal Research (5) 1-16
Thermal water ascending in a hot-spring system may cool by conduction of heat to the surrounding rock, by boiling, by mixing with cooler water, or by a combination of these processes. Complete or partial chemical reequilibration may occur as a result of this cooling. In spite of these complexities, in...
International cooperation in water resources
J.R. Jones, R.M. Beall, E.V. Giusti
1979, GeoJournal (3) 481-487
Advancements in hydrology proceeded slowly until the late 1800's when new ventures created a surge of interest and accomplishment. Progress waned again until the middle 20th century when an International Hydrological Decade was conceived, eventually receiving wide multinational support from governmental agencies and nongovernmental institutions. Organized by UNESCO, the Decade...
A review of numerical simulation of hydrothermal systems
J.W. Mercer, C.R. Faust
1979, Hydrological Sciences Bulletin (24) 335-344
Many advances in simulating single and two-phase fluid flow and heat transport in porous media have recently been made in conjunction with geothermal energy research. These numerical models reproduce system thermal and pressure behaviour and can be used for heat-transport problems other than those associated with geothermal energy development, such...

Hydrologic information for land-use planning, Fairbanks vicinity, Alaska
Gordon L. Nelson
1978, Open-File Report 78-959
The flood plain on the Chena and Tanana Rivers near Fairbanks, Alaska, has abundant water in rivers and in an unconfined alluvial aquifer. The principal source of ground water is the Tanana River, from which ground water flows northwesterly to the Chena River. Transmissivity of the aquifer commonly exceed 100...
A theoretical basis for exploration for native copper in northern Wisconsin
Walter S. White
1978, Circular 769
Exploration for native copper in the Keweenawan lavas of northern Wisconsin has been concentrated in areas of relatively shallow overburden that have sparse to numerous outcrops. Lack of success of this exploration suggests that if large deposits, comparable to those of northern Michigan, are present, they are more likely to...

Robert M. Beall
1978, Water Supply Paper 2042
A map of the Ohio River basin above the Muskingum River shows patterns of mean annual runoff for the new climatologic and hydrologic reference period, 1941-70, and provides an up-to-date, consistent basis for consideration of this streamflow characteristic. The primary data base consisted of 98 long-term gaging-station records collected within...

John Michael Kernodle
1978, Open-File Report 78-356
Two programs are documented which solve a discretized analytical equation derived to determine head changes at a point in a one-dimensional ground-water flow system. The programs, written for programmable calculators, are in widely divergent but commonly encountered languages and serve to illustrate the adaptability of the linear model to use...
