Magnitude and frequency of the floods of January 1997 in northern and central California; preliminary determinations
Richard A. Hunrichs, David A. Pratt, Robert W. Meyer
1998, Open-File Report 98-626
Preliminary determinations of the magnitude and frequency of peak flows resulting from the storms of December 1996 and January 1997 were made at 292 streamflow gaging stations located in 45 counties in northern and central California. Peak flows were the largest on record at 106 stations, and recurrence intervals were...
Evaluation of chemical data from selected sites in the Surface-Water Ambient Monitoring Program (SWAMP) in Florida
B. G. Katz, J.J. Collins
1998, Open-File Report 98-559
A cooperative study between the Florida Department of Environmental Protection (FDEP) and the U.S. Geological Survey was conducted to assess the integrity of selected water-quality data collected at 150 sites in the FDEP Surface-Water Ambient Monitoring Program (SWAMP) in Florida. The assessment included determining the consistency of the water-quality data...
Modified Mercalli intensities for some recent California earthquakes and historic San Francisco Bay Region earthquakes
William H. Bakun
1998, Open-File Report 98-584
Modified Mercalli Intensity (MMI) data for recent California earthquakes were used by Bakun and Wentworth (1997) to develop a strategy for bounding the location and moment magnitude M of earthquakes from MMI observations only. Bakun (Bull. Seismol. Soc. Amer., submitted) used the Bakun and Wentworth (1997) strategy to analyze 19th...
Corrections to "Estimating earthquake location and magnitude from seismic intensity data"
W. H. Bakun, C. M. Wentworth
1998, Open-File Report 98-614
The confidence parameters in Table 5 and Figures 7 -12 in Bakun and Wentworth (1997) were calculated using the site corrections for MI(4) rather than Bakun and Wentworth's (1997) preferred relation MI(3). The conclusions of Bakun and Wentworth (1997) are not changed by these corrections. The corrected Table 5 and...
Preliminary report on coal resources of the Wyodak-Anderson coal zone, Powder River Basin, Wyoming and Montana
Margaret S. Ellis, Gregory L. Gunther, Romeo M. Flores, Allen M. Ochs, Gary D. Stricker, Steven B. Roberts, Thomas T. Taber, Lisa R. Bader, John H. Schuenemeyer
1998, Open-File Report 98-789-A
The National Coal Resource Assessment (NCRA) project by the U.S. Geological Survey is designed to assess US coal with the greatest potential for development in the next 20 to 30 years. Coal in the Wyodak-Anderson (WA) coal zone in the Powder River Basin of Wyoming and Montana is plentiful, clean, and compliant with...
Bulk densities and porosities of Cenozoic and Cretaceous basin-filling strata and Cretaceous and older basement rocks, Los Angeles Basin, California, determined from measurements of core samples
L. A. Beyer, T. H. McCulloh
1998, Open-File Report 98-788
This report describes and provides a digital data file of selected bulk properties of subsurface rocks sampled in and around Los Angeles basin, California. Selected properties include measured dry bulk density (range 0.78 to 3.01 g/cm3), measured or estimated grain (matrix) density, calculated water saturated bulk density (range 1.47 to...
Water-level altitudes 1998, water-level changes 1977-98 and 1997-98, and compaction 1973-97 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
L.S. Coplin
1998, Open-File Report 98-96
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compaction since 1973 in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. The report, prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District,...
Review of Aquifer Test Results for the Lansdale Area, Montgomery County, Pennsylvania, 1980–95
Daniel J. Goode, Lisa A. Senior
1998, Open-File Report 98-294
Aquifer and aquifer-isolation test results in and around North Penn Area 6 Superfund site, Lansdale, Montgomery County, Pennsylvania are reviewed to provide estimated aquifer properties for use in a numerical model of ground-water flow. This review was made to support of remedial action investigations by U.S. Environmental Protection Agency (USEPA),...
Water-level altitudes 1998 and water-level changes 1990-98 and 1997-98 in the Chicot and Evangeline aquifers, Fort Bend County and adjacent areas, Texas
L.S. Coplin, H. X. Santos
1998, Open-File Report 98-95
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1990 in the Chicot and Evangeline aquifers in Fort Bend County and adjacent areas, Texas. The report, prepared in cooperation with the Ford Bend Subsidence District, presents maps for the Chicot and...
