Michael R. Stevens, Jennifer L. Flynn, Verlin C. Stephens, Kristine L. Verdin
2011, Scientific Investigations Report 2011-5047
During 2009, the U.S. Geological Survey, in cooperation with Gunnison County, initiated a study to estimate the potential for postwildfire debris flows to occur in the drainage basins occupied by Carbonate, Slate, Raspberry, and Milton Creeks near Marble, Colorado. Currently (2010), these drainage basins are unburned but could be burned...

James K. Otton
2011, Open-File Report 2011-1140
Studies of the natural environment in the Grants Mineral Belt in northwestern New Mexico have been conducted since the 1930s; however, few such investigations predate uranium mining and milling operations, which began in the early 1950s. This report provides an annotated bibliography of reports that describe the hydrology and geochemistry...

2011, Environmental Toxicology and Chemistry (30) 1213-1222
The acute oral toxicity of the anticoagulant rodenticide diphacinone was found to be over 20 times greater in American kestrels (Falco sparverius; median lethal dose 96.8 mg/kg body weight) compared with Northern bobwhite (Colinus virginianus) and mallards (Anas platyrhynchos). Modest evidence of internal bleeding was observed at necropsy, although histological...

2011, Ecology Letters (14) 274-281
Many ecosystems worldwide are dominated by introduced plant species, leading to loss of biodiversity and ecosystem function. A common but rarely tested assumption is that these plants are more abundant in introduced vs. native communities, because ecological or evolutionary-based shifts in populations underlie invasion success. Here, data for 26 herbaceous...
Coastal subsidence in Oregon, USA during the giant Cascadia earthquake of AD 1700
A. D. Hawkes, B. P. Horton, A.R. Nelson, C. H. Vane, Y. Sawai
2011, Quaternary Science Reviews (30) 364-376
Quantitative estimates of land-level change during the giant AD 1700 Cascadia earthquake along the Oregon coast are inferred from relative sea-level changes reconstructed from fossil foraminiferal assemblages preserved within the stratigraphic record. A transfer function, based upon a regional training set of modern sediment samples from Oregon estuaries, is calibrated...

R. M. Nielson, B. R. Gray, L.L. McDonald, P.J. Heglund
2011, Aquatic Botany (95) 221-225
Estimation of site occupancy rates when detection probabilities are <1 is well established in wildlife science. Data from multiple visits to a sample of sites are used to estimate detection probabilities and the proportion of sites occupied by focal species. In this article we describe how site occupancy methods can...

Neil C. Sturchio, J.K. Bohlke, Baohua Gu, Paul B. Hatzinger, W. Andrew Jackson
Mark Baskaran, editor(s)
2011, Book chapter, Handbook of environmental isotope geochemistry
Isotopic measurements can be used for tracing the sources and behavior of environmental contaminants. Perchlorate (ClO 4 − ) has been detected widely in groundwater, soils, fertilizers, plants, milk, and human urine since 1997, when improved analytical methods for analyzing ClO 4 −concentration became available for routine use....

2011, Conference Paper, Debris-flow hazards : mitigation, mechanics, prediction, and assessment : proceedings of 5th international conference : Padua, Italy, 14-17 June 2011
Recent advances in downscaling climate model precipitation predictions now yield spatially explicit patterns of rainfall that could be used to estimate shallow landslide susceptibility over large areas. In California, the United States Geological Survey is exploring community emergency response to the possible effects of a very large simulated storm event...
Entrainment of bed sediment by debris flows: results from large-scale experiments
Mark E. Reid, Richard M. Iverson, Matthew Logan, Richard G. LaHusen, Jonathan W. Godt, Julie P. Griswold
2011, Conference Paper, Debris-flow hazards : mitigation, mechanics, prediction, and assessment : proceedings of 5th international conference : Padua, Italy, 14-17 June 2011
When debris flows grow by entraining sediment, they can become especially hazardous owing to increased volume, speed, and runout. To investigate the entrainment process, we conducted eight largescale experiments in the USGS debris-flow flume. In each experiment, we released a 6 m3 water-saturated debris flow across a 47-m long, ~12-cm...

Linda Pickett Garinger, Aaron S. King, Andrew C. Ziegler
2011, Scientific Investigations Report 2011-5070
Declining water levels and concerns about the migration of a known saltwater plume upgradient from public supply wells prompted the City of Wichita to investigate the feasibility of using artificial recharge to replenish the water supply in the Equus Beds aquifer. After preliminary testing, the City of Wichita began Phase...
