Groundwater technical procedures of the U.S. Geological Survey
William L. Cunningham, Charles W. Schalk
2011, Techniques and Methods 1-A1
A series of groundwater technical procedures documents (GWPDs) has been released by the U.S. Geological Survey, Water-Resources Discipline, for general use by the public. These technical procedures were written in response to the need for standardized technical procedures of many aspects of groundwater science, including site and measuring-point establishment, measurement...
Spawning migration movements of Lost River and shortnose suckers in the Williamson and Sprague Rivers, Oregon, following the removal of Chiloquin Dam-2009 Annual Report
Craig M. Ellsworth, Scott P. VanderKooi
2011, Open-File Report 2011-1147
The Chiloquin Dam was located at river kilometer (rkm) 1.3 on the Sprague River near the town of Chiloquin, Oregon. The dam was identified as a barrier that potentially inhibited or prevented the upstream spawning migrations and other movements of endangered Lost River suckers (Deltistes luxatus), shortnose suckers (Chasmistes brevirostris),...
A geospatial approach to identify water quality issues for National Wildlife Refuges in Oregon and Washington
Jo Ellen Hinck, Kimberly Chojnacki, Susan E. Finger, Greg Linder, Kevin Kilbride
2011, Journal of Fish and Wildlife Management (2) 12-21
Many National Wildlife Refuges (Refuges) have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. Competing duties limit the time available for Refuge staff to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until...
A two-phase debris-flow model that includes coupled evolution of volume fractions, granular dilatancy, and pore-fluid pressure
David L. George, Richard M. Iverson
2011, Conference Paper, Debris-flow hazards : mitigation, mechanics, prediction, and assessment : proceedings of 5th international conference : Padua, Italy, 14-17 June 2011
Pore-fluid pressure plays a crucial role in debris flows because it counteracts normal stresses at grain contacts and thereby reduces intergranular friction. Pore-pressure feedback accompanying debris deformation is particularly important during the onset of debrisflow motion, when it can dramatically influence the balance of forces governing downslope acceleration. We consider...
Simulation of groundwater flow in a volatile organic compound-contaminated area near Bethpage, Nassau County, New York: A discussion of modeling considerations
Paul E. Misut
2011, Open-File Report 2011-1128
The 2010 Bethpage groundwater-flow model (ARCADIS, 2010) was based on a steady state assumption. Although it is widely acknowledged that significant water-level changes have occurred in the past, the reviewed model does not represent changing water levels. The steady state approach limits the effectiveness of the following: 1. identification of sources...

Kirk P. Smith
2011, Open-File Report 2011-1077
Records of water quantity, water quality, and meteorological parameters were continuously collected from three reservoirs, two primary streams, and five subbasin tributaries in the Cambridge, Massachusetts, drinking-water source area during water years 2007-08 (October 2006 through September 2008). Water samples were collected during base-flow conditions and storms in the Cambridge...

H. Bangum, O. Ritzmann, N. Maercklin, J.I. Faleide, Walter D. Mooney, Shane T. Detweiler
2011, Eos, Earth and Space Science News (86) 160-161
The Barents Sea and its surroundings is an epicontinental region which previously has been difficult to access, partly because of its remote Arctic location (Figure 1) and partly because the region has been politically sensitive. Now, however, this region, and in particular its western parts, has been very well surveyed...

Misidentification of freshwater mussel species (Bivalvia:Unionidae): Contributing factors, management implications, and potential solutions
Colin P. Shea, James T. Peterson, Jason M. Wisniewski, Nathan A. Johnson
2011, Journal of the North American Benthological Society (30) 446-458
Surveys of freshwater mussel populations are used frequently to inform conservation decisions by providing information about the status and distribution of species. It is generally accepted that not all mussels or species are collected during surveys, and incomplete detection of individuals and species can bias data and can affect inferences....

2011, Applied Geochemistry (26) S32-S35
The Prairie Pothole Region, which occupies 900,000 km2 of the north central USA and south central Canada, is one of the most important ecosystems in North America. It is characterized by millions of small wetlands whose chemistry is highly variable over short distances. The study involved the geochemistry of surface...

Clint C. Muhlfeld, Leslie A. Jones, E. William Schweiger, Isabel W. Ashton, Loren L. Bahls
2011, Park Science (28) 88-91
Didymosphenia geminata (didymo) is a freshwater alga native to North America, including Glacier National Park, Montana. It has long been considered a cold-water species, but has recently spread to lower latitudes and warmer waters, and increasingly forms large blooms that cover streambeds. We used a comprehensive monitoring data set from...
Statistical Comparisons of watershed scale response to climate change in selected basins across the United States
John Risley, Hamid Moradkhani, Lauren E. Hay, Steve Markstrom
2011, Earth Interactions (15) 1-26
In an earlier global climate-change study, air temperature and precipitation data for the entire twenty-first century simulated from five general circulation models were used as input to precalibrated watershed models for 14 selected basins across the United States. Simulated daily streamflow and energy output from the watershed models were used...
