Land subsidence caused by ground water withdrawal in urban areas
T.L. Holzer, A.I. Johnson
1985, GeoJournal (11) 245-255
At least eight urban areas in the world have encountered significant economic impact from land subsidence caused by pumping of ground water from unconsolidated sediment. The areas, most of which are coastal, include Bangkok, Houston, Mexico City, Osaka, San Jose, Shanghai, Tokyo, and Venice. Flooding related to decreased ground elevation...
TOPOGRAPHY, STRESSES, AND STABILITY AT YUCCA MOUNTAIN, NEVADA.
Henri Wolfs, William Z. Savage
1985, Conference Paper, Proceedings - Symposium on Rock Mechanics
Plane-strain solutions are used to analyze the influence of topography on the state of stress at Yucca Mountain, Nye County, Nevada. The results are in good agreement with the measured stress components obtained in drill holes by the hydraulic-fracturing technique, particularly those measured directly beneath the crest of the ridge,...
U. S. G. S. MODULAR GROUND-WATER FLOW MODEL: DESIGNED TO BE UNDERSTOOD AND ADAPTED.
Michael G. McDonald, Arlen W. Harbaugh
1985, Conference Paper
The paper discusses a carefully designed model program and its complementary complete description of all of the physical and mathematical concepts used in the model. The model program consists of a series of independent subroutines called modules. Modules are grouped by hydrologic function into 'packages. ' A report describing the...
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...
Hydrologic changes associated with the October 28, 1983, Idaho earthquake
R.L. Whitehead, R.W. Harper, H.G. Sisco
1985, Pure and Applied Geophysics PAGEOPH (122) 280-293
Significant hydrologic changes were observed after the magnitude 7.3 earthquake that occurred on October 28, 1983, in central Idaho. Groundwater levels rose by as much as 3 meters near the epicenter. Discharge in many streams and springs increased, in some instances by more than 100%. One warm spring ceased flowing...
INDUCED SEISMICITY MECHANISM AT THE GEYSERS, CALIFORNIA.
David Oppenheimer
1985, Conference Paper, Transactions - Geothermal Resources Council
Induced microearthquake activity at The Geysers geothermal reservoir is observed in the vicinity of eight geothermal steam power units. The earthquakes do not align with mapped faults but occur adjacent to steam wells. The sense of motion as deduced from focal mechanisms is strike-slip to reverse in the upper 1...

Impulsive radon emanation on a creeping segment of the San Andreas fault, California
C.-Y. King
1985, Pure and Applied Geophysics PAGEOPH (122) 340-352
Radon emanation was continuously monitored for several months at two locations along a creeping segment of the San Andreas fault in central California. The recorded emanations showed several impulsive increases that lasted as much as five hours with amplitudes considerably larger than meteorologically induced diurnal variations. Some of the radon...
ON PREDICTING INFRAGRAVITY ENERGY IN THE SURF ZONE.
Sallenger Jr., Robert A. Holman
Billy L. Edge, editor(s)
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...
Dissolution of alkaline earth sulfates in the presence of montmorillonite
D. D. Eberl, Edward R. Landa
1985, Water, Air, & Soil Pollution (25) 207-214
In a study of the effect of montmorillonite on the dissolution of BaSO4 (barite), SrSO4 (celestite), and 226Ra from U mill tailings, it was found that: (1) More of these substances dissolve in an aqueous system that contains montmorillonite than dissolve in a similar system without clay, due to the...
APPLICATION OF THE AERIAL PROFILING OF TERRAIN SYSTEM.
Edward J. Cyran
1985, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
The U. S. Geological Survey has completed the performance evaluation flight tests of the Aerial Profiling of Terrain System (APTS) and is now performing a series of application tests to determine its effectiveness and efficiency as an earth-science data collection tool. These tests are designed to evaluate the APTS at...

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...
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...
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...
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...
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...
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...
