Suspended-sediment concentration and pool sedimentation data for the Gibbon River, Yellowstone National Park, Wyoming, September 2000 through October 2001
Peter R. Wright, Ronald B. Zelt
2003, Open-File Report 2003-185
This report presents data on streamflow, suspended-sediment concentration, geomorphic measurements of pools, and particle-size distribution of surficial bed material, collected along a 5-mile reach of the Gibbon River in Yellowstone National Park. The study was done in cooperation with the National Park Service. The Park Service was concerned about the...
Determination of upstream boundary points on southeastern Washington streams and rivers under the requirements of the Shoreline Management Act of 1971
Johnna L. Higgins
2003, Water-Resources Investigations Report 2003-4042
Regulation of the shorelines of the State of Washington, as mandated by the Shoreline Management Act of 1971, requires knowledge of the locations on streams and river reaches where specific regulatory criteria are satisfied. The U.S. Geological Survey conducted a study in 1971 to determine the upstream boundary points of...
Four models used for numerical simulation of a borehole radar antenna
Karl J. Ellefsen, David L. Wright
2003, Open-File Report 2003-155
In this report are four different models that represent an antenna used by personnel at the U.S. Geological Survey for crosswell investigations. The four models vary in complexity and concomitantly the accuracy with which they represent the actual antenna. These models are used in numerical simulations of the antenna to...
Descriptions of mineral occurrences and interpretation of mineralized rock geochemical data in the Stikine geophysical survey area, Southeastern Alaska
Cliff D. Taylor
2003, Open-File Report 2003-154
Detailed descriptions of some of the more significant mineral occurrences in the Stikine Airborne Geophysical Survey Project Area are presented based upon site-specific examinations by the U.S. Geological Survey in May of 1998. Reconnaissance geochemical data on unmineralized igneous and sedimentary host rocks, and mineralized rocks are also presented and...
The plan to coordinate NEHRP post-earthquake investigations
Thomas L. Holzer, Roger D. Borcherdt, Craig D. Comartin, Robert D. Hanson, Charles R. Scawthorn, Kathleen Tierney, T. Leslie Youd
2003, Circular 1242
This is the plan to coordinate domestic and foreign post-earthquake investigations supported by the National Earthquake Hazards Reduction Program (NEHRP). The plan addresses coordination of both the NEHRP agencies—Federal Emergency Management Agency (FEMA), National Institute of Standards and Technology (NIST), National Science Foundation (NSF), and U. S. Geological Survey (USGS)—and...
Bacterial contamination at Huntington Beach, California — Is it from a local offshore wastewater outfall?
Jingping Xu, Marlene Noble, Leslie Rosenfeld, John Largier, Peter Hamilton, Burt Jones, James W. Hendley II, Peter H. Stauffer
2003, Fact Sheet 024-03
During the summers of 1999 and 2000, beaches at Huntington Beach, California, were repeatedly closed to swimming because of high bacteria levels in the surf zone. The city’s beaches are a major recreational and commercial resource, normally attracting millions of visitors each summer. One possible source of the bacterial contamination...
Archive of Boomer and Chirp Seismic Reflection Data Collected During USGS Cruise 01RCE02, Southern Louisiana, April and May 2001
Karynna Calderon, Shawn V. Dadisman, James G. Flocks, Dana S. Wiese
2003, Open-File Report 2003-88
In April and May of 2001, the U.S. Geological Survey conducted a geophysical study of the Mississippi River Delta, Atchafalaya River Delta, and Shell Island Pass in southern Louisiana. This study was part of a larger USGS River Contaminant Evaluation (RCE) Project. This disc serves as an archive of unprocessed...
Comparison of temperature, specific conductance, pH, and dissolved oxygen at selected basic fixed sites in south-central Texas, 1996-98
Patricia B. Ging, Cassi L. Otero
2003, Open-File Report 2003-87
One component of the surface-water part of the U.S. Geological Survey National Water-Quality Assessment Program is the use of continuous water-quality monitors to help characterize the spatial and temporal distribution of general water quality in relation to hydrologic conditions. During 1996-98, six continuous water-quality monitors in the South-Central Texas study...
Java Programs for Using Newmark's Method and Simplified Decoupled Analysis to Model Slope Performance During Earthquakes
Randall W. Jibson, Matthew W. Jibson
2003, Open-File Report 2003-5
Landslides typically cause a large proportion of earthquake damage, and the ability to predict slope performance during earthquakes is important for many types of seismic-hazard analysis and for the design of engineered slopes. Newmark's method for modeling a landslide as a rigid-plastic block sliding on an inclined plane provides a...
Simulation of ground-water flow and land subsidence in the Antelope Valley ground-water basin, California
David A. Leighton, Steven P. Phillips
2003, Water-Resources Investigations Report 2003-4016
Antelope Valley, California, is a topographically closed basin in the western part of the Mojave Desert, about 50 miles northeast of Los Angeles. The Antelope Valley ground-water basin is about 940 square miles and is separated from the northern part of Antelope Valley by faults and low-lying hills. Prior to...
Geologic map of the Buckeystown quadrangle, Frederick and Montgomery Counties, Maryland, and Loudoun County, Virginia
Scott Southworth, David K. Brezinski
2003, Geologic Quadrangle 1800
The Buckeystown quadrangle is underlain mostly by rocks of the western Piedmont province and a portion of the eastern Blue Ridge province. The western Piedmont province is underlain by Late Proterozoic(?) and Lower Cambrian(?) metasedimentary rocks of the Westminster terrane, Lower and Middle Cambrian metasedimentary rocks and Upper Cambrian to...
