J. Todd Petty, Jeff L. Hansbarger, Brock M. Huntsman, Patricia M. Mazik
2012, Transactions of the American Fisheries Society (141) 1060-1073
We quantified movements of brook trout Salvelinus fontinalis and brown trout Salmo trutta in a complex riverscape characterized by a large, open-canopy main stem and a small, closed-canopy tributary in eastern West Virginia, USA. Our objectives were to quantify the overall rate of trout movement and relate movement behaviors to...

Design and maintenance of a network for collecting high-resolution suspended-sediment data at remote locations on rivers, with examples from the Colorado River
Ronald E. Griffiths, David J. Topping, Timothy Andrews, Glenn E. Bennett, Thomas A. Sabol, Theodore S. Melis
2012, Techniques and Methods 8-C2
Management of sand and finer sediment in fluvial settings has become increasingly important for reasons ranging from endangered-species habitat to transport of sediment-associated contaminants. In all rivers, some fraction of the suspended load is transported as washload, and some as suspended bed material. Typically, the washload is composed of silt-and-clay-size...

Rotenone persistence model for montane streams
Peter J. Brown, Alexander V. Zale
2012, Transactions of the American Fisheries Society (141) 560-569
The efficient and effective use of rotenone is hindered by its unknown persistence in streams. Environmental conditions degrade rotenone, but current label instructions suggest fortifying the chemical along a stream based on linear distance or travel time rather than environmental conditions. Our objective was to develop models that use measurements...
Explaining differences between bioaccumulation measurements in laboratory and field data through use of a probabilistic modeling approach
Henriette Selck, Ken Drouillard, Karen Eisenreich, Albert A. Koelmans, Annemette Palmqvist, Anders Ruus, Daniel Salvito, Irv Schultz, A. Robin Stewart, Annie Weisbrod, Nico W. van den Brink, Martine van den Heuvel-Greve
2012, Integrated Environmental Assessment and Management (8) 42-63
In the regulatory context, bioaccumulation assessment is often hampered by substantial data uncertainty as well as by the poorly understood differences often observed between results from laboratory and field bioaccumulation studies. Bioaccumulation is a complex, multifaceted process, which calls for accurate error analysis. Yet, attempts to quantify and compare propagation...

Variance of discharge estimates sampled using acoustic Doppler current profilers from moving boats
Carlos M. Garcia, Leticia Tarrab, Kevin Oberg, Ricardo Szupiany, Mariano I. Cantero
2012, Journal of Hydraulic Engineering

The model focuses on the random processes in the sampled flow field and has been developed using statistical methods currently available for uncertainty...
Vulnerability of recently recharged groundwater in principal aquifers of the United States to nitrate contamination
Jason J. Gurdak, Sharon L. Qi
2012, Environmental Science & Technology (46) 6004-6012
Recently recharged water (defined here as <60 years old) is generally the most vulnerable part of a groundwater resource to nonpoint-source nitrate contamination. Understanding at the appropriate scale the interactions of natural and anthropogenic controlling factors that influence nitrate occurrence in recently recharged groundwater is critical to support best management...

Timothy D. Counihan, Jill M. Hardiman, Dave S. Burgess, Katrina E. Simmons, Glen S. Holmberg, Josh A. Rogala, Rochelle R. Polacek
2012, Open-File Report 2012-1130
Hydroelectric development on the mainstem Columbia River has created a series of impoundments that promote the production of native and non-native piscivores. Reducing the effects of fish predation on migrating juvenile salmonids has been a major component of mitigating the effects of hydroelectric development in the Columbia River basin. Extensive...
