Aquatic organism passage at road-stream crossings—synthesis and guidelines for effectiveness monitoring
Robert L. Hoffman, Jason B. Dunham, Bruce P. Hansen
2012, Open-File Report 2012-1090
Restoration and maintenance of passage for aquatic organisms at road-stream crossings represents a major management priority, involving an investment of hundreds of millions of dollars (for example, U.S. Government Accounting Office, 2001). In recent years, passage at hundreds of crossings has been restored, primarily by replacing barrier road culverts with...

National assessment of hurricane-induced coastal erosion hazards--Gulf of Mexico
Hilary F. Stockdon, Kara S. Doran, David M. Thompson, Kristin L. Sopkin, Nathaniel G. Plant, Asbury H. Sallenger Jr.
2012, Open-File Report 2012-1084
Sandy beaches provide a natural barrier between the ocean and inland communities, ecosystems, and resources. However, these dynamic environments move and change in response to winds, waves, and currents. During a hurricane, these changes can be large and sometimes catastrophic. High waves and storm surge act together to erode beaches...
Evidence for mid-Holocene shift in depositional style in Mobile Bay, Alabama
David Twichell, Kyle Kelso, Elizabeth A. Pendleton
2012, Open-File Report 2012-1081
The Holocene stratigraphy of Mobile Bay, Alabama, was mapped using a combination of high-resolution seismic data and sediment cores to refine changes in the bay's evolution during this time. The base of the Holocene-era stratigraphy is an erosional surface formed during the last glacial maximum. Overlying Holocene deposits are primarily...

2012, Open-File Report 2012-1085
This report provides a perspective on the amount of water necessary for conventional gold heap-leach operations. Water is required for drilling and dust suppression during mining, for agglomeration and as leachate during ore processing, to support the workforce (requires water in potable form and for sanitation), for minesite reclamation, and...
Observations of coastal sediment dynamics of the Tijuana Estuary Fine Sediment Fate and Transport Demonstration Project, Imperial Beach, California
Jonathan A. Warrick, Kurt J. Rosenberger, Angela Lam, Joanne C. T. Ferreira, Ian M. Miller, Meg Rippy, Jan Svejkovsky, Neomi Mustain
2012, Open-File Report 2012-1083
Coastal restoration and management must address the presence, use, and transportation of fine sediment, yet little information exists on the patterns and/or processes of fine-sediment transport and deposition for these systems. To fill this information gap, a number of State of California, Federal, and private industry partners developed the Tijuana...

In 2006, the...
An annotated bibliography for lamprey habitat in the White Salmon River, Washington
M. Brady Allen
2012, Open-File Report 2012-1086
The October 2011 decommissioning of Condit Dam on the White Salmon River at river kilometer (rkm) 5.3 removed a significant fish passage barrier from the White Salmon River basin for the first time in nearly a century. This affords an opportunity to regain a potentially important drainage basin for Pacific...
