The Salt Cedar and Russian Olive Control Demonstration Act of 2006 (Public Law 109-320; hereafter the Act) directs the Department of the Interior to submit a report to Congress1 that includes an assessment of several issues surrounding these two nonnative trees, now dominant components of the vegetation along many rivers...
Automated masking of cloud and cloud shadow for forest change analysis using Landsat images
Chengquan Huang, Nancy Thomas, Samuel N. Goward, Jeffery G. Masek, Zhiliang Zhu, J.R.G. Townshend, James Vogelmann
2010, International Journal of Remote Sensing (31) 5449-5464
Accurate masking of cloud and cloud shadow is a prerequisite for reliable mapping of land surface attributes. Cloud contamination is particularly a problem for land cover change analysis, because unflagged clouds may be mapped as false changes, and the level of such false changes can be comparable to or many...
Monitoring and characterizing natural hazards with satellite InSAR imagery
Zhong Lu, Jixian Zhang, Yonghong Zhang, Daniel Dzurisin
2010, Annals of GIS (16) 55-66
Interferometric synthetic aperture radar (InSAR) provides an all-weather imaging capability for measuring ground-surface deformation and inferring changes in land surface characteristics. InSAR enables scientists to monitor and characterize hazards posed by volcanic, seismic, and hydrogeologic processes, by landslides and wildfires, and by human activities such as mining and fluid extraction...

Paul J. Umhoefer, L. Sue Beard, Melissa Lamb, editor(s)
2010, Book chapter, Miocene tectonics of the Lake Mead Region, central basin and range
The Lake Mead region contains major Miocene disruptions of structures formed during Mesozoic tectonic shortening. Erosion by the Colorado River and its tributaries has produced exceptional exposures of diverse structures and basin deposits recording the disruptions. Here we provide an overview of the results of studies of these features that...

How humans and nature have shaped the San Francisco Estuary since the Gold Rush
B. E. Jaffe
2009, Report, The Pulse of the Estuary: Monitoring and Managing Water Quality in the San Francisco Estuary
The San Francisco Estuary has undergone dramatic changes since the Gold Rush, as both natural forces and human activities have added and removed massive quantities of sediment, primarily sand and mud. A long-term perspective of sediment movement and patterns of sediment deposition and erosion is vital for effective management of...
Evaluating the power to detect temporal trends in fishery independent surveys: A case study based on Gillnets Set in the Ohio waters of Lake Erie for walleye
Tyler Wagner, Christopher S. Vandergoot, Jeff Tyson
2009, North American Journal of Fisheries Management (29) 805-816
Fishery-independent (FI) surveys provide critical information used for the sustainable management and conservation of fish populations. Because fisheries management often requires the effects of management actions to be evaluated and detected within a relatively short time frame, it is important that research be directed toward FI survey evaluation, especially with...

Christine M. Wieben, Ronald J. Baker
2009, Report, Barnegat Bay Partnership State of the Bay Technical Report
Based on the most recent and most accurate data available through 2008, the total load of nitrogen to the Barnegat Bay‐Little Egg Harbor (BB‐LEH) estuary from the most substantial sources (surface water, including surface‐water discharge and direct storm runoff; ground‐water discharge; and atmospheric deposition) is estimated to be 650,000 kilograms...
The observed relationship between wave conditions and beach response, Ocean Beach, San Francisco, CA
J.E. Hansen, P.L. Barnard
2009, Journal of Coastal Research 1771-1775
Understanding how sandy beaches respond to storms is critical for effective sediment management and developing successful erosion mitigation efforts. However, only limited progress has been made in relating observed beach changes to wave conditions, with one of the major limiting factors being the lack of temporally dense beach topography and...

Stephen D. Sebestyen, Elizabeth W. Boyer, James B. Shanley
2009, Journal of Geophysical Research (114)
[1] In coming decades, higher annual temperatures, increased growing season length, and increased dormant season precipitation are expected across the northeastern United States in response to anthropogenic forcing of global climate. We synthesized long-term stream hydrochemical data from the Sleepers River Research Watershed in Vermont, United States, to explore the...

2009, Report, Development and interpretation of the ADTI-WP2 Leaching Column Method (kinetic test procedure for the prediction of coal mine drainage quality). EPA Method 1627
Rocks associated with coal beds typically include shale, sandstone, and (or) limestone. In addition to common rock-forming minerals, all of these rock types may contain sulfide and sulfate minerals, various carbonate minerals, and organic material. These different minerals have inherently different solubility characteristics, as well as different acid-generating or acid-neutralizing...
Estimating phosphorus concentrations following alum treatment using apparent settling velocity
John Panuska, Dale M. Robertson
2009, Lake and Reservoir Management (15) 28-38
he apparent settling velocity (Vs) is a term used in empirical, steady-state, mass-balance lake models to represent the net phosphorus flux from the water column. The Vollenweider (1969) mixed-reactor lake model was rearranged and used to calculate Vs values for total phosphorus (TP) for three lakes treated with alum to...
Rehabilitation of Delavan Lake, Wisconsin
Dale M. Robertson, Gerald L. Goddard, D.R. Helsel, Kevin L. MacKinnon
2009, Lake and Reservoir Management (16) 155-176
A comprehensive rehabilitation plan was developed and implemented to shift Delavan Lake, Wisconsin, from a hypereutrophic to a mesotrophic condition. The plan was threefold: (1) reduce external phosphorus (P) loading by applying Best Management Practices in the watershed, enhance an existing wetland, and short-circuit the inflows through...
