Preliminary report on geophysics of the Verde River headwaters region, Arizona
Victoria E. Langenheim, J. S. Duval, Laurie Wirt, Ed DeWitt
2000, Open-File Report 2000-403
This report summarizes the acquisition, data processing, and preliminary interpretation of a high-resolution aeromagnetic and radiometric survey near the confluence of the Big and Little Chino basins in the headwaters of the Verde River, Arizona. The goal of the aeromagnetic study is to improve understanding of the geologic framework as...
Graphs and tables used to describe electrical measurements of samples of unconsolidated materials, USGS Petrophysical Laboratory, Denver
David L. Campbell, Robert Horton
2000, Open-File Report 2000-377
The U.S. Geological Survey Petrophysical Laboratory (PetLab) in Denver CO measures electrical properties of samples of earth materials collected by U.S. Geological Survey personnel. This report describes the standard graphs and tables produced by PetLab to present geoelectrical measurements made on samples of unconsolidated materials....
Droughts in Georgia
Nancy L. Barber, Timothy C. Stamey
2000, Open-File Report 2000-380
Droughts do not have the immediate effects of floods, but sustained droughts can cause economic stress throughout the State. The word 'drought' has various meanings, depending on a person's perspective. To a farmer, a drought is a period of moisture deficiency that affects the crops under cultivation - even two...
Flood tracking chart for the Upper San Jacinto River Basin near Houston, Texas
Dana L. Barbie
2000, Open-File Report 2000-387
The “Flood Tracking Chart for the Upper San Jacinto River Basin near Houston, Texas” can be used to track river stage and to assess flood-crest information during substantial storms. Water-surface elevation during a flood will provide emergency-response personnel, residents, and the traveling general public essential information to make informed decisions...
Velocity and stage data collected in a laboratory flume for water-surface slope determination using a pipe manometer
Jonathan K. Lee, H. M. Visser, H. L. Jenter, M. P. Duff
2000, Open-File Report 2000-393
U.S. Geological Survey (USGS) hydrologists and ecologist are conducting studies to quantify vegetative flow resistance in order to improve numerical models of surface-water flow in the Florida Everglades. Water-surface slope is perhaps the most difficult of the flow resistance parameters to measure in the Everglades due to the very low...
A note on scrap in the 1992 U.S. input-output tables
George M. Swisko
2000, Open-File Report 2000-313
Introduction A key concern of industrial ecology and life cycle analysis is the disposal and recycling of scrap. One might conclude that the U.S. input-output tables are appropriate tools for analyzing scrap flows. Duchin, for instance, has suggested using input-output analysis for industrial ecology, indicating that input-output economics can trace the stocks and flows...
Fate and transport modeling of selected chlorinated organic compounds at Operable Unit 3, U.S. Naval Air Station, Jacksonville, Florida
J. Hal Davis
2000, Open-File Report 2000-255
Ground water contaminated by the chlorinated organic compounds trichloroethene (TCE), cis-dichloroethene (DCE), and vinyl chloride (VC) has been found in the surficial aquifer beneath the Naval Aviation Depot at the U.S. Naval Air Station, Jacksonville, Florida. The affected area is designated Operable Unit 3 (OU3) and covers 134 acres adjacent...
Summary of precipitation data for the Black Hills area of South Dakota, water years 1931-98
Daniel G. Driscoll, Ghaith R. Hamade, Scott J. Kenner
2000, Open-File Report 2000-329
Long-term precipitation records are sum-marized for the Black Hills area of South Dakota. Precipitation data are available for numerous gaging locations; however, few gages have continuous, long-term records, and periods of missing record are common. Thus, a geographic information system (GIS) utilizing an inverse-distance weighting method was developed to generate...
1890 and 1990 Bathymetry of Florida Bay
Mark Hansen, Nancy T. DeWitt
2000, Open-File Report 2000-0347
This Open File Report contains bathymetric data collected in Florida Bay by the US Geological Survey, South Florida Place-Based Studies Program using SANDS (System for Accurate Nearshore Depth Surveying). SANDS is a USGS developed, high precision bathymetric system which integrates depth soundings, boat motion, and GPS positioning needed for nearshore...
A primer on the occurrence of coalbed methane in low-rank coals, with special reference to its potential occurrence in Pakistan
John R. SanFilipo
2000, Open-File Report 2000-293
Introduction: This report compiles and updates a series of correspondence that took place between 1998 and early 2000 among the author and representatives of various consulting groups operating in the coal sector of Pakistan. The purpose of the original correspondence was to introduce basic concepts of coalbed methane (CBM) in...
Mapping Typha Domingensis in the Cienega de Santa Clara Using Satellite Images, Global Positioning System, and Spectrometry
Richard D. Sanchez, Earl E. Burnett, Fred Croxen
2000, Open-File Report 2000-314
The Cienega de Santa Clara, Sonora, Mexico, a brackish wetland area created near the delta of the Colorado River from drainage effluent flowing from the United States since 1977, may undergo changes owing to the operation of the Yuma Desalting Plant in the United States. This has become the largest...
Investigation of polyethylene passive diffusion samplers for sampling volatile organic compounds in ground water at Davis Global Communications, Sacramento, California, August 1998 to February 1999
Don A. Vroblesky, J. W. Borchers, T.R. Campbell, Willey Kinsey
2000, Open-File Report 2000-307
Fourteen wells were instrumented with diffusion samplers as a test to determine whether the samplers could be used to obtain representative volatile organic compound concentrations at a study site in Sacramento, California. Single diffusion samplers were placed in 10-foot-long well screens, and multiple diffusion samplers were positioned in 20-foot-long well...
Reprocessing of multi-channel seismic-reflection data collected in the Beaufort Sea
Warren F. Agena, Myung W. Lee, P. E. Hart
2000, Open-File Report 2000-460
Contained on this set of two CD-ROMs are stacked and migrated multi-channel seismic-reflection data for 65 lines recorded in the Beaufort Sea by the United States Geological Survey in 1977. All data were reprocessed by the USGS using updated processing methods resulting in improved interpretability. Each of the two CD-ROMs...
