What is a picture worth? A history of remote sensing
Gerald K. Moore
1979, Hydrological Sciences Bulletin (24) 477-485
Remote sensing is the use of electromagnetic energy to measure the physical properties of distant objects. It includes photography and geophysical surveying as well as newer techniques that use other parts of the electromagnetic spectrum. The history of remote sensing begins with photography. The origin of other types of remote...

An industrial waste liquid containing organonitrile compounds and nitrate ion has been injected into the lower limestone of the Floridan aquifer near Pensacola, Florida since June 1975. Chemical analyses of water from monitor wells and backflow from the injection well indicate that organic carbon compounds are converted to CO2 and...
Hydraulic potential in Lake Michigan bottom sediments
K. Cartwright, C.S. Hunt, G.M. Hughes, R.D. Brower
1979, Journal of Hydrology (43) 67-78
The magnitude and direction of groundwater flux in the bottom sediments of Lake Michigan were deduced from measurements made during three shipboard cruises between 1973 and 1975. These factors affect the geochemical environment of the sediments and therefore the distribution of trace elements reported to be present. The near-shore, sandy-bottom...
Measurement of fluid velocity using temperature profiles: Experimental verification
K. Cartwright
1979, Journal of Hydrology (43) 185-194
Temperature profiling has been used to predict the rate and direction of groundwater movement. A controlled field experiment was conducted to ascertain the validity of the rate calculations made using this method. The vertical velocity, or leakage, of groundwater between two aquifers was calculated utilizing both hydrologic and temperature measurements...
Hydrogeology of glacial-terrain lakes, with management and planning applications
S.M. Born, S.A. Smith, D.A. Stephenson
1979, Journal of Hydrology (43) 7-43
The subject of the relationship between groundwater and lakes is characterized by sparse information and, in general, has received limited attention by hydrologists. Nevertheless, the hydrogeologic regime of lakes must be adequately assessed in order to intelligently manage lakes and their related shorelands. This paper is a compilation of hydrogeologic...
Effects of karst and geologic structure on the circulation of water and permeability in carbonate aquifers
V. T. Stringfield, J. R. Rapp, R.B. Anders
1979, Journal of Hydrology (43) 313-332
The results of the natural processes caused by solution and leaching of limestone, dolomite, gypsum, salt and other soluble rocks, is known as karst. Development of karst is commonly known as karstification, which may have a pronounced effect on the topography, hydrology and environment, especially where such karst features as...
Contribution of groundwater modeling to planning
J.E. Moore
1979, Journal of Hydrology (43) 121-128
The consideration of groundwater in water-resource planning frequently has been neglected because many planners believed that groundwater could not be adequately evaluated in terms of availability, quality, cost of development, or effect of development on the surface-water supply. The development of predictive groundwater models now provides the water planner with...
Simulated changes in potentiometric levels resulting from groundwater development for phosphate mines, west-central Florida
W.E. Wilson, J. M. Gerhart
1979, Journal of Hydrology (43) 491-515
A digital model of two-dimensional groundwater flow was used to predict changes in the potentiometric surface of the Floridan aquifer resulting from groundwater development for proposed and existing phosphate mines during 1976-2000. The modeled area covers 15,379 km2in west-central Florida.In 1975, groundwater withdrawn from the Floridan aquifer for irrigation, phosphate...
Risk preferences and flood insurance
Emil D. Attanasi, Michael R. Karlinger
1979, American Journal of Agricultural Economics (61) 490-495
A detailed theoretical model characterizing the individual's decision to purchase flood insurance is specified and the magnitude of the risk parameter is estimated using data based on transactions of flood insurance purchases. Empirical results for several samples of this subset of the general population indicated that consumers exhibited a relatively...
Monitoring of subsurface injection of wastes, Florida
John Vecchioli
1979, Groundwater (17) 244-249
Injection of waste liquids into Florida's subsurface is physically feasible in many places but should be accompanied by monitoring of the waste-receiving aquifer system in addition to the injection facility. Monitoring of the interaction of factors including hydrogeologic conditions, well construction, waste volumes and characteristics, and potable-water sources is desirable...
Hydrologic conditions in Broward County, Florida, 1976
T.R. Beaven
1979, Open-File Report 79-1258
During the 1976 water year, rainfall was 3.6 percent below average in Broward County, Fla. Water levels in the Pompano Beach and Dixie well fields were lower during the peak of the 1976 dry season than the peak of the record low dry season in 1971. Flow in the major...
Hydrologic and geologic data from the Upper East Coast Planning Area, southeast Florida
Wesley L. Miller
1979, Open-File Report 79-1543
The Upper East Coast Planning Area, one of five designated planning areas in the South Florida Water Management District, consists of St. Lucie, Martin, and eastern Okeechobee Counties. Existing hydrologic and geologic data have been compiled as a base for additional investigations to determine the water-bearing characteristics of the shallow...
Digital model of the Bayou Bartholomew alluvial aquifer stream system, Arkansas
J.E. Reed, Matthew E. Broom
1979, Open-File Report 79-685
A digital model of the Bayou Bartholomew aquifer-stream system in Arkansas was calibrated for the purpose of predicting hydrologic responses to stresses of water development. The simulated-time span for model calibration was from 1953 to 1970, during which time the system was stressed largely by ground- and surface-water diversions for...
Geohydrologic impacts of coal development in the Narragansett Basin, Massachusetts and Rhode Island
Michael H. Frimpter, Anthony Maevsky
1979, Water Supply Paper 2062
The hydrologic impacts of possible coal mining in the 900-square-mile Carboniferous Narragansett Basin in southeastern New England are described. Geophysical tests and hydrologic observations were made in thirteen 3-inch-diameter test holes which were 330 to 1,500 feet deep. Fractures and lithology, including graphite and coal, were identified and located from...
Simulation of wetlands forest vegetation dynamics
Richard L. Phipps
1979, Ecological Modelling (7) 257-288
A computer program, SWAMP, was designed to simulate the effects of flood frequency and depth to water table on southern wetlands forest vegetation dynamics. By incorporating these hydrologic characteristics into the model, forest vegetation and vegetation dynamics can be simulated. The model, based on data from the White River National...
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,...

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...
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...

Phil A. Kammerer Jr., Marvin G. Sherrill
1979, Water-Resources Investigations Report 79-95
The Nederlo Creek basin, in the "Driftless Area" of southwest Wisconsin, is geographically and hydrologically similar to other small basins in the area. Topography is rugged, with approximately 400 feet of relief between the boundary ridge tops and the valley floor. The water-retention structures (a dry floodwater- retention structure and...
Some basic considerations in the design of hydrologic data networks
Marshall E. Moss
1979, Water Resources Research (15) 1673-1676
Two preeminent considerations of data network design are the random nature of the hydrologic phenomena and the uses that will be made of the data. Information distilled from the data is usually measured in a parametric statistical sense, although the data user is more concerned with the integrated measure of...
Trees as indicators of past movements on the San Andreas Fault
R. E. Wallace, Valmore C. LaMarche Jr.
1979, Earthquake Information Bulletin (USGS) (11) 127-131
Trees are sources of information about fault movements that have occurred before the earliest historical reports. This kind of evidence can be used to improve estimates of when earthquakes will recur on faults known to be seismically active and to identify active faults that have no record of movement during...
