2006, Water Data Report UT-05-1
Water-resources data for the 2005 water year for Utah consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 165 gaging stations; stage and contents for 8...
Water-Quality Data for the Lower Russian River Basin, Sonoma County, California, 2003-2004
Robert Anders, Karl Davidek, Kathryn M. Koczot
2006, Data Series 168
In 2003, the U.S. Geological Survey, in cooperation with the Sonoma County Water Agency, began a study to determine the chemical, microbiological, and isotopic composition of the surface water and ground water in selected areas of the Lower Russian River Basin, Sonoma County, California. This report is a compilation of...
Coastal circulation and sediment dynamics in Hanalei Bay, Kauai, Part I, Measurements of waves, currents, temperature, salinity and turbidity; June–August, 2005
Curt D. Storlazzi, M. Kathy Presto, Joshua B. Logan, Michael E. Field
2006, Open-File Report 2006-1085
High-resolution measurements of waves, currents, water levels, temperature, salinity and turbidity were made in Hanalei Bay, northern Kauai, Hawaii, during the summer of 2005 to better understand coastal circulation and sediment dynamics in coral reef habitats. A series of bottom-mounted instrument packages were deployed in water depths of 10 m...
Water resources data--North Dakota water year 2005, Volume 1. Surface water
S.M. Robinson, R.F. Lundgren, B.A. Sether, S.W. Norbeck, J.M. Lambrecht
2006, Water Data Report ND-05-1
Water-resources data for the 2005 water year for North Dakota consists of records of discharge, stage, and water quality for streams; contents, stage, and water quality for lakes and reservoirs; and water levels and water quality for ground-water wells. Volume 1 contains records of water discharge for 107 streamflow-gaging stations;...
Assessment of undiscovered oil and gas resources of the Mackenzie Delta province, North America, 2004
Mitchell E. Henry, Thomas S. Ahlbrandt, Ronald R. Charpentier, Donald L. Gautier, Timothy R. Klett, Richard M. Pollastro, Christopher J. Schenk, Gregory F. Ulmishek
2006, Fact Sheet 2006-3002
Using a geology-based assessment methodology, the U.S. Geological Survey estimated a mean of 40 trillion cubic feet of undiscovered nonassociated gas, a mean of 10.5 billion barrels of undiscovered oil (with 46.6 trillion cubic feet of associated gas), and a mean of 4.0 billion barrels of undiscovered natural gas liquids...
MODFLOW-2005, the U.S. Geological Survey modular ground-water model - documentation of shared node local grid refinement (LGR) and the boundary flow and head (BFH) package
Steffen W. Mehl, Mary C. Hill
2006, Techniques and Methods 6-A12
This report documents the addition of shared node Local Grid Refinement (LGR) to MODFLOW-2005, the U.S. Geological Survey modular, transient, three-dimensional, finite-difference ground-water flow model. LGR provides the capability to simulate ground-water flow using one block-shaped higher-resolution local grid (a child model) within a coarser-grid parent model. LGR accomplishes...
User guide to the UNC process and three utility programs for computation of nonlinear confidence and prediction intervals using MODFLOW-2000
Steen Christensen, Richard L. Cooley
2006, Techniques and Methods 6-A10
This report introduces and documents the Uncertainty (UNC) Process, a new Process in MODFLOW-2000 that calculates uncertainty measures for model parameters and for predictions produced by the model. Uncertainty measures can be computed by various methods, but when regression is applied to calibrate a model (for example when using the...
Magnetic properties, acid neutralization capacity, and net acid production of rocks in the Animas River Watershed Silverton, Colorado
Anne E. McCafferty, Douglas B. Yager, Radley M. Horton, Sharon F. Diehl
2006, Conference Paper, 19th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems
Federal land managers along with local stakeholders in the Upper Animas River watershed near Silverton, Colorado are actively designing and implementing mine waste remediation projects to mitigate the effects of acid mine drainage from several abandoned hard rock metal mines and mills. Local source rocks with high acid neutralization capacity...
Occurrence of MTBE and other gasoline oxygenates in CWS source waters
Janet M. Carter, Stephen J. Grady, Gregory C. Delzer, Bart Koch, John S. Zogorski
2006, Journal - American Water Works Association (98) 91-104
Results from two national surveys indicate that the gasoline oxygenate methyl tertiary butyl ether (MTBE) is one of the most frequently detected volatile organic compounds in source waters used by community water systems in the United States. Three other ether oxygenates were detected infrequently but almost always co-occurred with MTBE....
