Joseph W. Long, Nathaniel G. Plant
Jane McKee Smith, Patrick Lynett, editor(s)
2010, Conference Paper, Proceedings of 32nd International Conference on Coastal Engineering
A modeling system that considers both long- and short-term process-driven shoreline change is presented. The modeling system is integrated into a data assimilation framework that uses sparse observations of shoreline change to correct a model forecast and to determine unobserved model variables and free parameters. Application of the assimilation algorithm...

G.L. Wingard, J.W. Hudley, F.E. Marshall
2010, Fact Sheet 2010-3047
Restoring the greater Everglades ecosystem of south Florida is arguably the largest ecosystem restoration effort to date. A critical goal is to return more natural patterns of flow through south Florida wetlands and into the estuaries, but development of realistic targets requires acknowledgement that ecosystems are constantly evolving and changing...

Jennifer A. Dougherty, Peter W. Swarzenski, Richard S. Dinicola, Martin Reinhard
2010, Journal of Environmental Quality (39) 1173-1180
Organic contaminants, such as pharmaceuticals and personal care products (PPCPs), pose a risk to water quality and the health of ecosystems. This study was designed to determine if a coastal community lacking point sources, such as waste water treatment plant effluent, could release PPCPs, herbicides, and plasticizers at detectable levels...

Dorothy F. Payne
2010, Conference Paper, Proceedings of the 21st Salt Water Intrusion Meeting, Azores, Portugal, 2010
Sea‐level rise and changes in precipitation patterns may contribute to the occurrence and affect the rate of saltwater contamination in the Hilton Head Island, South Carolina area. To address the effects of climate change on saltwater intrusion, a threedimensional, finite‐element, variable‐density, solute‐transport model was developed to simulate different rates of...

Calibrating recruitment estimates for mourning doves from harvest age ratios
David A. Miller, David L. Otis
2010, Journal of Wildlife Management (74) 1070-1078
We examined results from the first national-scale effort to estimate mourning dove (Zenaida macroura) age ratios and developed a simple, efficient, and generalizable methodology for calibrating estimates. Our method predicted age classes of unknown-age wings based on backward projection of molt distributions from fall harvest collections to preseason banding. We...
Climate change and climate systems influence and control the atmospheric dispersion of desert dust: implications for human health
Dale W. Griffin
Richard C. Ragaini, editor(s)
2010, Conference Paper, International Seminar on Nuclear War and Planetary Emergencies 42nd session
The global dispersion of desert dust through Earth’s atmosphere is greatly influenced by temperature. Temporal analyses of ice core data have demonstrated that enhanced dust dispersion occurs during glacial events. This is due to an increase in ice cover, which results in an increase in drier terrestrial cover. A shorter...
Hydraulic alterations resulting from hydropower development in the Bonneville Reach of the Columbia River
James R. Hatten, Thomas R. Batt
2010, Northwest Science (84) 207-222
We used a two-dimensional (2D) hydrodynamic model to simulate and compare the hydraulic characteristics in a 74-km reach of the Columbia River (the Bonneville Reach) before and after construction of Bonneville Dam. For hydrodynamic modeling, we created a bathymetric layer of the Bonneville Reach from single-beam and multi-beam echo-sounder surveys,...
Discriminating silt-and-clay from suspended-sand in rivers using side-looking acoustic profilers
Scott Wright, David J. Topping, Cory A. Williams
2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010: Hydrology and sedimentation for a changing future: Existing and emerging issues
The ability to accurately monitor suspended-sediment flux in rivers is needed to support many types of studies, because the sediment that typically travels in suspension affects geomorphology and aquatic habitat in a variety of ways (e.g. bank and floodplain deposition, bar morphology, light penetration and primary productivity, tidal wetland deposition...

Michael T. Lee
2010, Conference Paper
Suspend-sediment and water-quality data were measured during two periods of high flow, one during April 20-23, 2009 and a second during September 22-November 3, 2009. On the basis of streamflow and continuous and discrete water-quality measurements, the two periods of high flow had different flood and nutrient loading characteristics. Some...
An automated and universal method for measuring mean grain size from a digital image of sediment
Daniel D. Buscombe, David M. Rubin, Jonathan A. Warrick
2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010 : Hydrology and sedimentation for a changing future : existing and emerging issues
Existing methods for estimating mean grain size of sediment in an image require either complicated sequences of image processing (filtering, edge detection, segmentation, etc.) or statistical procedures involving calibration. We present a new approach which uses Fourier methods to calculate grain size directly from the image without requiring calibration. Based...
