Lognormal field size distributions as a consequence of economic truncation
E. D. Attanasi, L.J. Drew
1985, Journal of the International Association for Mathematical Geology (17) 335-351
The assumption of lognormal (parent) field size distributions has for a long time been applied to resource appraisal and evaluation of exploration strategy by the petroleum industry. However, frequency distributions estimated with observed data and used to justify this hypotheses are conditional. Examination of various observed field size distributions across...

Chung Jin S.Lunardini Virgil J.Chakrabarti S.K.Wang Y.S.Sodhi D.S.Karal K., editor(s)
1985, Conference Paper, Proceedings of the International Offshore Mechanics and Arctic Engineering Symposium
Besides providing an exact solution for steady-state heat conduction processes (Laplace Poisson equations), the CVBEM (complex variable boundary element method) can be used for the numerical error analysis of domain model solutions. For problems where soil water phase change latent heat effects dominate the thermal regime, heat transport can be...

1985, Conference Paper, Proceedings of the Coastal Engineering Conference
Flow data were obtained in the surf zone across a barred profile during a storm. RMS cross-shore velocities due to waves in the intragravity band (wave periods greater than 20 s) had maxima in excess of 0. 5 m/s over the bar crest. For comparison to measured spectra, synthetic spectra...

Highly acidic contaminated water is moving through a shallow aquifer and interacting with streams near Globe, Arizona. Dissolved concentrations reach 3,000 mg/L iron, 150 mg/L copper, and 16,400 mg/L total dissloved solids; pH is as low as 3. 6. Samples from 16 PVC-cased observation wells include uncontaminated, contaminated, transition, and...

John R. Gray, Charles A. Peters
Graves Donald H., editor(s)
1985, Conference Paper, University of Kentucky, Office of Engineering Services, (Bulletin) UKY BU
Runoff, sediment transport, and precipitation were measured in three gaged basins composing two-thirds of the 20-acre site, and in a 3. 5-acre basin located 0. 3 mile south of the site. Locations and dimensions of surface collapses at the site were recorded by the site contractor. Volumes of collapsed material...
MAJOR SOURCE OF SIDE-LOOKING AIRBORNE RADAR IMAGERY FOR RESEARCH AND EXPLORATION: THE U. S. GEOLOGICAL SURVEY.
Allan N. Kover, John Edwin Jones
Carver Keith R., editor(s)
1985, Conference Paper, Digest - International Geoscience and Remote Sensing Symposium (IGARSS)
The US Geological Survey (USGS) instituted a program in 1980 to acquire side-looking airbore radar (SLAR) data and make these data readily available to the public in a mosaic format comparable to the USGS 1:250,000-scale topographic map series. The SLAR data are also available as strip images at an acquisition...

REGIONAL GROUND-WATER-QUALITY NETWORK DESIGN.
William E. Templin
Schmidt Kenneth D., editor(s)
1985, Conference Paper
This paper describes the approach used in designing a regional network to monitor the complex ground-water-quality conditions in the San Joaquin Valley, California. The actual network approximates the ideal network with the constraint of primarily using wells that are already being monitored by someone for some purpose. Further inventories of...
Evidence for lower crustal ductile strain localization in southern New York
Mark D. Zoback, W.H. Prescott, S.W. Krueger
1985, Nature (317) 705-707
Historic triangulation data have been analysed to determine whether intraplate seismicity is associated with ongoing ductile deformation in the lower crust. The model we have attempted to test is basically analogous to strain accumulation and release along plate-boundary strike-slip faults like the San Andreas Fault in California. That is, beneath...

1985, Conference Paper, NASA Conference Publication
This preliminary report examines those radiometric characteristics of the Landsat 4 Thematic Mapper (TM) that can be established without absolute calibration of spectral data. Analysis is based largely on radiometrically raw (B type) data of three daytime and two nighttime scenes; in most scenes, a set of 512 lines were...

Processing of Landsat imagery to map surface mineral alteration on the Alaska Peninsula: A section in USGS research on mineral resources, 1985 program and abstracts
Frederic H. Wilson, James York
1985, Circular 949
Landsat images were digitally processed to facilitate assessment of the mineral resources of the Port Moller, Stepovak Bay, and Simeonof Island 1:250,000 quadrangles. Field mapping and assessment of these quadrangles were begun in 1983 as part of the Alaska Mineral Resource Assessment Program (AMRAP). It was quickly realized that time...
Freshwater runoff and salinity distribution in the Loxahatchee River estuary, southeastern Florida, 1980-82
G.M. Russell, B. F. McPherson
1984, Water-Resources Investigations Report 83-4244
Freshwater mixed with seawater over a distance of 5 to 10 river miles in the Loxahatchee River estuary during a recent study. Large freshwater inflows vertically stratified the estuary and shifted the mixing zone seaward. In the northwest fork of the estuary, the saltwater-freshwater interface moved daily about 0.5 to...
Hydrogeology of a zone of secondary permeability in the surficial aquifer of eastern Palm Beach County, Florida
L. J. Swayze, W. L. Miller
1984, Water-Resources Investigations Report 83-4249
The surficial aquifer is the primary source of freshwater for the heavily developed coastal area in eastern Palm Beach County, Florida. Well fields are generally located in a discontinuous zone of higher secondary permeability, the northernmost extension of the Biscayne aquifer in the surficial aquifer, that extends from the Juno...
Nutrient input from the Loxahatchee River Environmental Control District sewage-treatment plant to the Loxahatchee River Estuary, southeastern Florida
W. H. Sonntag, B. F. McPherson
1984, Water-Resources Investigations Report 84-4020
Two test discharges of treated-sewage effluent were made to the Loxahatchee River in February and September 1981 from the ENCON sewage-treatment plant to document nutrient loading and downstream transport of the effluent to the estuary under maximum daily discharge allowable by law (4 million gallons per day). Concentrations of total...
Quality of water recovered from a municipal effluent injection well in the Floridan aquifer system, Pompano Beach, Florida
D.J. McKenzie, G. A. Irwin
1984, Water-Resources Investigations Report 84-4100
Approximately 69 million gallons of backflow from an injection well used for the disposal of secondary treated municipal effluent in the Floridan aquifer system near Pompano Beach, Florida, was periodically sampled for inorganic quality from March 1975 through March 1977. Analyses of the backflow effluent showed a concomitant increase in...
Attenuation of stormwater contaminants from highway runoff within unsaturated limestone, Dade County, Florida
Bradley G. Waller, Howard Klein, Lawrence J. Lefkoff
1984, Water-Resources Investigations Report 84-4083
Infiltration of stormwater in heavily urbanized parts of Dade County, Florida, is a prime source of recharge to the unconfined Biscayne aquifer, the sole source of drinking water for southeast Florida. Ponded stormwater at the test site contained greater concentrations of lead, zinc, manganese, nitrogen (except nitrate), and phosphorus than...

Terry F. Rees, Jess M. Cleveland, Kenneth L. Nash
1984, Nuclear Technology (65) 131-137
The speciation of plutonium, neptunium, and americium was determined in groundwaters from four sources in the Basin and Range Province: the lower carbonate aquifer, Nevada Test Site (NTS) (Crystal Pool); alluvial fill, Frenchman Flat, NTS (well 5C); Hualapai Valley, Arizona (Red Lake south well); and Tularosa Basin, New Mexico (Rentfrow...

Marti L. Miller, Julie A. Dumoulin, S.W. Nelson
1984, Circular 939
The lower Tertiary Orca Group is juxtaposed against the Upper Cretaceous Valdez Group along the Contact fault system (Winkler and Plafker, 1974, 198; Plafker and others, 1977)(fig. 33). In both groups, turbidites are the dominant rock type, with lesser mafic volcanic rocks (table 10). The Valdez Group, on the north,...

1984, Utah Geological and Mineralogical Survey Water-Resources Bulletin 24
Determinations of peak discharge for floods of May to June 1983 were made for 11 streams along the northern Wasatch Front from Salt Lake City to North Ogden. At nine of the streams, the floods during the spring of 1983 equaled or exceeded the 100-year flood. The peak discharge at...
