Terry A. Kenney, Susan G. Buto
2008, Scientific Investigations Report 2008-5233
Predicted inundation maps for the Fremont River and Bull Creek in Hanksville, Utah, were developed using one-dimensional hydraulic models. Estimates of the 1-percent chance (100-year) peak streamflows were determined for the Fremont River and Bull Creek study reaches by using annual peak series data from streamflow-gaging stations and regional peak-flow...

Carl S. Carlson, Leslie A. DeSimone, Peter K. Weiskel
2008, Scientific Investigations Report 2008-5132
Continued population growth and land development for commercial, industrial, and residential uses have created concerns regarding the future supply of potable water and the quantity of ground water discharging to streams in the area of Interstate 495 in eastern Massachusetts. Two ground-water models developed in 2002-2004 for the Assabet and...

Jonathan W. Musser
2008, Scientific Investigations Report 2008-5223
Potential flow characteristics of future flooding along a 4.8-mile reach of the Flint River in Albany, Georgia, were simulated using recent digital-elevation-model data and the U.S. Geological Survey finite-element surface-water modeling system for two-dimensional flow in the horizontal plane (FESWMS-2DH). The model was run at four water-surface altitudes at the...

Allan D. Randall, Anne Finch
2008, Scientific Investigations Report 2008-5087
Water levels beneath parts of Averill Park, a residential hamlet in an upland area of till-mantled shale bedrock in east-central New York, have declined in response to increased withdrawals from new wells. Similar experiences in many upland localities in the northeastern United States have resulted in awareness that the rate...

Simulation of ground-water flow in the Shenandoah Valley, Virginia and West Virginia, using variable-direction anisotropy in hydraulic conductivity to represent bedrock structure
Richard M. Yager, Scott C. Southworth, Clifford I. Voss
2008, Scientific Investigations Report 2008-5002
Ground-water flow was simulated using variable-direction anisotropy in hydraulic conductivity to represent the folded, fractured sedimentary rocks that underlie the Shenandoah Valley in Virginia and West Virginia. The anisotropy is a consequence of the orientations of fractures that provide preferential flow paths through the rock, such that the direction of...

Faith A. Fitzpatrick, Marie C. Peppler, John F. Walker, William J. Rose, Robert J. Waschbusch, James L. Kennedy
2008, Scientific Investigations Report 2008-5235
In June 2008, heavy rain caused severe flooding across southern Wisconsin. The floods were aggravated by saturated soils that persisted from unusually wet antecedent conditions from a combination of floods in August 2007, more than 100 inches of snow in winter 2007-08, and moist conditions in spring 2008. The flooding...
Projecting cumulative benefits of multiple river restoration projects: an example from the Sacramento-San Joaquin River system in California
G. Mathias Kondolf, Paul L. Angermeier, Kenneth Cummins, Thomas Dunne, Michael Healey, Wim Kimmerer, Peter B. Moyle, Dennis Murphy, Duncan Patten, Steve F. Railsback, Denise J. Reed, Robert B. Spies, Robert Twiss
2008, Environmental Management (42) 933-945
Despite increasingly large investments, the potential ecological effects of river restoration programs are still small compared to the degree of human alterations to physical and ecological function. Thus, it is rarely possible to “restore” pre-disturbance conditions; rather restoration programs (even large, well-funded ones) will nearly always involve multiple small projects,...

2008, Human-Wildlife Conflicts (2) 48-59
White-tailed deer (Odocoileus virginianus) mortalities (n = 4,433) caused by collisions with automobiles during 2003 were modeled in 35 counties in eastern South Dakota. Seventeen independent variables and 5 independent variable interactions were evaluated to explain deer mortalities. A negative binomial regression model (Ln Y = 1.25 – 0.12 [percentage...
Non-random temporary emigration and the robust design: Conditions for bias at the end of a time series: Section VIII
Catherine A. Langtimm
2008, Book chapter, Modeling demographic processes in marked populations
Deviations from model assumptions in the application of capture–recapture models to real life situations can introduce unknown bias. Understanding the type and magnitude of bias under these conditions is important to interpreting model results. In a robust design analysis of long-term photo-documented sighting histories of the endangered Florida manatee,...

2008, Water Resources Research (45)
Understanding how changes in land use affect water quality of public supply wells (PSW) is important because of the strong influence of land use on water quality, the rapid pace at which changes in land use are occurring in some parts of the world, and the large...

Blase A. Reardon, J. T. Harper, Daniel B. Fagre
2008, Conference Paper, Proceedings of the Mass Balance Measurement and Modelling Workshop
Glacier National Park, Montana, USA, contains 27 cirque glaciers, most less than 1 km2 and together comprising about 17 km2. These glaciers lie at relatively low elevation (2000 – 3000 m a.s.l.) and latitude (48o N) and have undergone dramatic retreat since the mid-nineteenth century, when an estimated 150 glaciers...

Coastal Louisiana ecosystem assessment and restoration program: The role of ecosystem forecasting in evaluating restoration planning in the Mississippi River Deltaic Plain
Robert Twilley, Brady Couvillion, Imtiaz Hossain, Carola Kaiser, Alaina Owens, Gregory D. Steyer, Jenneke M. Visser
2008, Conference Paper, Mitigating impacts of natural hazards on fishery ecosystems
The development of ecosystem management plans to restore and rehabilitate natural resources requires an understanding of how specific ecological mechanisms regulate the structure and function of ecosystems. To achieve restoration goals, comprehensive plans and engineering designs must effectively change environmental drivers at the regionallevel to reduce stress conditions at the local environment...

2008, Conference Paper
A key issue faced in dam removal is the rate and timing of remobilization and discharge of stored reservoir sediments following the removal. Different removal strategies can result in different trajectories of upstream sediment transport and knickpoint migration. We examine this issue of for the Marmot Dam removal in Sandy...
