St. Joseph River at Elkhart, Indiana, Flood-Inundation HEC-RAS Model

Zachary W. Martin
Flood profiles were computed for the USGS streamgage 04101000, St. Joseph River at Elkhart, Ind., reach by means of a one-dimensional, step-backwater hydraulic modeling software developed by the U.S. Army Corps of Engineers. The hydraulic model was calibrated using the current stage-discharge rating at the USGS streamgage 04101000, St. Joseph River at Elkhart, Ind., and the documented high-water marks from the flood of March 1982. The hydraulic model was then used to compute six water-surface...

Fire impacts on permafrost in Alaska: Geophysical and other field data collected in 2014

Burke Minsley, Pastick (CTR), Neal J, Bruce K. Wylie, Dana R N Brown & Andy Kass
Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and resilience of different landscapes to permafrost degradation are needed. Geophysical and other field observations reveal details of both...

Middle Rio Grande Multitemporal Land Cover Classifications - 1935, 1962, 1987, 1999, and 2014

Roy E. Petrakis
The San Acacia Reach of the Middle Rio Grande has experienced multiple management and river flow fluctuations, resulting in threats to its riparian and aquatic ecosystems. This research used remote sensing data, GIS, a review of management decisions, and an assessment of climate to quantify how riparian vegetation has been altered over time. This research focused on four management phases from 1935-2014, each highlighting different management practices and climate-driven river patterns, providing unique opportunities to...

Organic matter decomposition along coastal wetland landscape gradient from tidal freshwater forested wetland to oligohaline marsh in Southeastern U.S.A. (2010-2011)

Camille L. Stagg, Donald R. Schoolmaster, Ken W. Krauss, Nicole Cormier & William H. Conner
Coastal wetlands significantly contribute to global carbon storage potential. Sea-level rise and other climate change-induced disturbances threaten coastal wetland sustainability and carbon storage capacity. It is critical that we understand the mechanisms controlling wetland carbon loss so that we can predict and manage these resources in anticipation of climate change.

Will fluctuations in salt marsh - mangrove dominance alter vulnerability of a subtropical wetland to sea-level rise?

Karen L. McKee
To avoid submergence during sea-level rise, coastal wetlands build soil surfaces vertically through accumulation of inorganic sediment and organic matter. At climatic boundaries where mangroves are expanding and replacing salt marsh, wetland capacity to respond to sea-level rise may change. To compare how well mangroves and salt marshes accommodate sea-level rise, we conducted a manipulative field experiment in a subtropical plant community in the rapidly subsiding Mississippi River Delta. Experimental plots were established in spatially...

Digital elevation models of the State Route 530 landslide near Oso, Washington, July 2014 to July 2015

Scott W. Anderson
Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. Due to the photogrammetric methods used to collect these surveys, there may be substantial artifacts near the edges of the surveys, in areas of vegetation, or over extents of bare water, and should be used with caution in these areas. Details of the collection and processing of...

William F. Coon, Elizabeth A. Nystrom & John F. Wernly
From July 14-20, 2016, the U.S. Geological Survey, in cooperation with the City of Ithaca, New York, conducted a bathymetric survey of the Cayuga Inlet flood-control channel and selected mouths of tributaries to Cayuga Inlet and Cayuga Lake in Ithaca, New York. U.S. Geological Survey personnel collected bathymetric data using an acoustic Doppler current profiler. The survey plan produced a dense dataset of water depths that were converted to bottom elevations by subtracting the depths...

Laura A. DeCicco, Lori A. Sprague, Jenny C. Murphy, Gretchen P. Oelsner, Henry M. Johnson, James A. Falcone & Edward G. Stets
In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has been conducted on streams and rivers throughout the Nation. Outside of the NAWQA...

Temperature data for study of shallow mountain bedrock limits seepage-based headwater climate refugia, Shenandoah National Park, Virginia

Martin Briggs, John W Lane, Craig D Snyder, Eric A White, Zachary C Johnson, David L Nelms & Nathaniel P Hitt
A combination of long-term daily temperature records and depth to bedrock measurements were used to parameterize one-dimensional models of shallow aquifer vertical heat transport in Shenandoah National Park, VA, USA. Spatially discontinuous roving water surface and bank temperatures surveys were performed with a handheld thermal infrared camera in September and December 2015 along the main channel of a headwater stream supporting coldwater-dependent brook trout (Salvelinus fontinalis). We also installed vertical arrays of thermal data loggers...

Anna G. Boegehold, Karim Alame, Nicholas S Johnson & Donna R. Kashian
These data contain information about sub-lethal effects of cyanobacteria exposure on quagga mussel. Sub-lethal effects of cyanobacteria exposure on quagga mussel (Dreissena rostriformis bugensis) sperm were evaluated. After inducing mussels to spawn using serotonin, sperm were collected and exposed to 11 cultures of cyanobacteria including Anabaena flos-aquae, Aphanizomenon flos-aquae, Dolichospermum lemmermanii, Gloeotrichia echinulata, five cultures of Microcystis aeruginosa, M. wesenbergii, and Planktothrix suspensa. Sperm motility, using endpoints of cumulative distance traveled and mean velocity, was...

Hydrodynamic Data of Bushy Park Reservoir, South Carolina 2013-2015

Paul A. Conrads & Timothy H. Lanier
The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the City of Charleston and the surrounding areas including the industries in the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, there are taste-and-odor water-quality concerns. The U.S. Geological Survey (USGS) worked in cooperation with the Charleston Water System to study the hydrology and...
