The 2009-2010 El Nino: Hydrologic Relief To U.S. Regions, Glenn A. Tootle, Thomas C. Piechota, Oubeidillah Aziz, William Paul Miller, Venkat Lakshmi, John A. Dracup, Carly Jerla

Civil and Environmental Engineering and Construction Faculty Research

Current forecasts by the U.S. National Oceanic and Atmospheric Administration (NOAA) are that the Pacific Ocean will experience El Niño conditions in late 2009 and into 2010. These forecasts are similar to past El Niño events in 1972–1973, 1982–1983, 1986–1987, and 2002–2003.

Evaluating the hydrologic conditions for these past El Niño events reveals that during these times, surface water supply conditions improved in many parts of the United States, including the Southeast, Midwest, and Southwest. At the same time, the Pacific Northwest and other specific regions of the United States experienced below-average water supply conditions. This is consistent with the …

The Effect Of Consumerism And Regulation On Household Solid Waste Management In The United States And Germany: A Comparative Study, Amir Vafa

School of Natural Resources: Dissertations, Theses, and Student Research

Private household recycling is a significant aspect of consumerism in economically developed countries and the inevitable question of household waste management has gained more importance among municipalities in recent years. The present study examined the effect of regulation on household solid waste management. Within a comparative, qualitative framework, the study explored and evaluated the pro-regulatory effects in Germany and the anti-regulatory policies in the United States by means of comparing two similar communities, Lincoln, Nebraska and Augsburg, Germany. By examining the present legislations, official documents, legal and operational procedures, and other relevant artifacts, laws, regulations and the degree of their …

The Ecological Advantages Of Nuclear Power, Fred P. Bosselman

All Faculty Scholarship

Major electric utilities are deciding whether to build nuclear power plants. How will their decision affect ecological processes and systems, both in the United States and globally? The article makes three arguments: (1) if nuclear power plants are not built, the gap will be filled by more coal-fired power plants; (2) the impact of coal-fired power plants on ecological processes and systems is likely to be increasingly disastrous; and (3) nuclear power’s ecological impacts are likely to be neutral or even positive.

Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew

Physics & Astronomy Faculty Publications

Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the fossil fuel mining locations created by the Kentucky Geological Survey geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single plain 1602 ft projection. This data was then exported into a spreadsheet showing latitude and longitude for each point to be used for modeling at different scales to determine the fractal dimension of the set. Following the porosity and diffusivity studies of Tarafdar and Roy[1] we extract fractal dimensions of the fossil fuel mining locations and search for evidence of scaling laws for the set of deposits. The …

A Review Of Offshore Wind Technology And The Development Of The Virginia Coastline And Outer Continental Shelf, Ryan D. Geary

Masters Theses, 2010-2019

Offshore wind power is an increasingly viable resource that is being considered by many coastal States in the U.S for development. This thesis provides a recommendation concerning the foundations that will be needed for the construction of offshore wind farms off the coast of Virginia. To accomplish this I reviewed current and prototype underwater foundation technologies in order to establish viable options for developers to use. I was also able to analyze a case study that conducted “an analysis and survey of the experiences and lessons learned by developers of offshore wind farms” in Europe. This case study focuses mainly …

A Simulation Model For Triclosan Concentrations In The North And Middle Rivers, Virginia, Preeyaporn Songkiatisak

Masters Theses, 2010-2019

Incidences of fish kills and intersex phenomena have occurred extensively in the Shenandoah River since 2004. Pharmaceuticals including triclosan have been detected at low concentrations in the Shenandoah River. Scientists hypothesize that triclosan, an antibacterial agent, may be one of the pharmaceuticals that is responsible for fish kills and intersex phenomena. Methyl triclosan (MTS) were found in fish tissues at a significantly higher concentration in the part of the Shenandoah River where fish kills are present compared to a non-impact river. Triclosan is widely used in personal care products, such as soaps, shampoos, and toothpastes and is rinsed down the …

Analysis Of Expedient Field Decontamination Methods For The Xmx/2l-Mil High-Volume Aerosol Sampler, Brandon C. Laroche

Theses and Dissertations

The XMX/2L-MIL is a high volume air sampler used by the Air Force Bioenvironmental Engineering community to collect biological aerosols. Without a verified decontamination technique, however, the XMX cannot be used effectively. The objective of this study was to evaluate several proposed methods for expedient field decontamination of the XMX. This study centered on the inactivation of Bacillus atrophaeus spores and vegetative Erwinia herbicola organisms from the XMX inner canister. The goals in this investigation were twofold: 1) to verify the antimicrobial efficacy of a 10% bleach solution and 2) to determine if wiping the components with a bleach-soaked paper …

Nest And Brood Survival And Habitat Selection Of Ring-Necked Pheasants And Greater Prairie-Chickens In Nebraska, Ty Matthews

School of Natural Resources: Dissertations, Theses, and Student Research

Ring-Necked Pheasant (Phasianus colchicus) and Greater Prairie-chicken (Tympanuchus cupido pinnatus) populations have declined in the Midwest since the 1960’s. Research has suggested decreased nest and brood survival are the major causes of this decline due to the lack of suitable habitat. Habitat degradation has been attributed to the shift to larger crop fields, lower diversity of crops, and more intensive pesticide and herbicide use. A primary goal of the Conservation Reserve Program (CRP) is to mitigate the loss of wildlife habitat. Early research found that CRP increased the amount of suitable nesting and brood rearing cover …

Development Of The Mask Scentometer, A Comparison Of Ambient Odor Assessment Methods, And Their Application In Ground Truthing Atmospheric Dispersion Models, Christopher G. Henry

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

This dissertation is organized as four stand-alone papers. Paper No. 1 describes the development of the Mask Scentometer and reports dilution ratios measured during use by twelve different people. Dilution ratios at the Mask Scentometer’s five dilution-to-threshold (D/T) settings were found to be 0.35, 1, 2, 4.5 and 18. In Paper No.’s 2 and 4, ambient odor assessment methods were compared in both controlled laboratory conditions and in the field. Laboratory analysis of ambient air samples using dynamic triangular forced-choice olfactometry (DTFCO) did not correlate well with any of the ambient odor assessment methods. Average intensity-predicted D/T was roughly five …

Satellite-Based Estimation Of Chlorophyll-A Concentration In Turbid Productive Waters, Wesley Moses

School of Natural Resources: Dissertations, Theses, and Student Research

Inland, coastal, and estuarine waters, which are often turbid and biologically productive, play a crucial role in maintaining global bio-diversity and are of immense value to aquatic life as well as human-beings. Concentration of chlorophyll-a (chl-a) is a key indicator of the trophic status of these waters, which should be regularly monitored to ensure that their ecological balance is not disturbed. Remote sensing is a powerful tool for this.

Due to the optical complexity of turbid productive waters, standard algorithms that use blue and green reflectances are unreliable for estimating chl-a concentration. Algorithms based on red and near-infrared (NIR) reflectances …

Observations Of Badgers Preying On Black-Tailed Prairie Dogs, Daniel S. Licht

The Prairie Naturalist

American badgers (Taxidea taxus) often visit black-tailed prairie dog (Cynomys ludovicianus) colonies, most likely in search of prey (Lomolino and Smith 2004, Shaughnessy and Cifelli 2004). Badgers are well suited to hunting fossorial prey such as prairie dogs by excavating burrows and capturing individuals belowground (Lindzey 2003). However, the ecological literature is sparse regarding details of how badgers hunt and capture prairie dogs underground. Eads and Biggins (2008) documented three occurrences of a badger excavating prairie dogs. That badger (apparently the same individual) had a den within the prairie dog town where captures occurred. This note …

Mortality Of Cranes (Gruidae) Associated With Powerlines Over A Major Roost On The Platte River, Nebraska, Gregory D. Wright, Timothy J. Smith, Robert K. Murphy, Jeffery T. Runge, Robert R. Harms

The Prairie Naturalist

Two 69-kilovolt powerlines spanning the Platte River in south central Nebraska are suspected to cause substantial mortality to sandhill cranes (Grus canadensis) and pose a threat to endangered whooping cranes (G. americana) that roost overnight on the river during spring and fall migrations. Most studies of crane collisions with powerlines in the region have focused on counts of carcasses away from night roosts on the river and none have accounted for potential biases in detecting carcasses. We found 61 carcasses of sandhill cranes below over-river segments of the two powerlines during 4 March to 7 April …

Long Distance Molt Migration By A Giant Canada Goose From Eastern South Dakota, Bobby J. Anderson, Charles D. Dieter

The Prairie Naturalist

To reduce crop damage by resident giant Canada geese (Schaible et al. 2005), the South Dakota Department of Game, Fish and Parks (SDGFP) initiated a program to reduce goose nesting success in eastern South Dakota. One management tool used by SDGFP personnel was the destruction of giant Canada goose nests. When a giant Canada goose has its nest destroyed, they are known to initiate a molt migration (Mykut 2002, Luukkonen et aI. 2008). We attached Platform Transmitting Terminals (PTT; model ST -19) to document and describe molt migrations of giant Canada geese following nest destruction. We captured 3 adult nesting …

Noteworthy Winter Prey Of Short-Eared Owls In Southern Texas: A Case Study, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa

The Prairie Naturalist

The winter range of North American short-eared owls (Asio flammeus) encompasses much of the United States, including southern Texas, where it is a common winter resident (Oberholser 1974, Rappole and Blacklock 1985). Winter food habits of short-eared owls are relatively weJl documented, but the majority of investigations have been conducted in eastern Canada and northeastern U.S. (Clark 1975, Holt 1993); midwestern U.S. (Colvin and Spaulding 1983); and British Columbia and Pacific northwestern U.S. (Bogiatto et al. 2001). The short-eared owl has a narrow trophic niche, generally preying on small mammals, with voles (Microtus spp.) and deer mice …

Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge

The Prairie Naturalist

I examined patterns of bison (Bison bison L.) hair use by passerine birds nesting in the Tallgrass Prairie Preserve, Osage County, Oklahoma, 2002-2004. I collected and dissected 103 nests of 15 species into their constituent components. Nests were predominately composed of herbaceous material such as grass stems and leaves. Woody material and mud were rarely used. Bison hair was the most prominent zoological material used in nests, with lesser amounts and occurrence of arthropod silk, snake skin, feathers, jack rabbit (Lepus californicus Oray) fur, and man-made materials such as cellophane and string. At least one nest of 13 …

Monitoring Meadows With A Modified Robel Pole In The Northern Black Hills, South Dakota, Daniel W, Uresk, Daryl E. Mergen, Ted A. Benzon

The Prairie Naturalist

We used a modified Robel pole to measure vegetation for a study conducted in the northern Black Hills, South Dakota. Objectives were to determine the relationship between visual obstruction readings and clipped standing herbage, and develop guidelines for monitoring standing herbage. The relationship between visual obstruction readings and standing herbage was linear and regression coefficients were significant (P≤ 0.001). Herbage ranged from 140 to 3313 kg· ha-1 with a mean of 1386 kg· ha^-1 (SE = 320 kg· ha^-1) for 123 transects. Visual obstruction readings (VOR) ranged from 0.6 to 30.4 (number of 1.27 cm bands …

Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer

Earth and Soil Sciences

Human induced disruption of the environment is prevalent in every culture. In Brazil, the effects of massive deforestation have become apparent since the nineteen eighties. However, along with deforestation, and a coinciding loss in an economic resource for the country, is a significant loss of natural habitat and species extinction. The Amazon in Brazil contains a large proportion of the world’s species diversity that is threatened by the socio-economic activities of modern Brazilian culture. Historically and presently, indigenous groups have contributed to insignificant levels of ecological disruption and are themselves threatened by the activities of modern Brazilians. The effects of …

Development Of Regional Hydraulic Geometry Curves For The Santa Cruz Mountains, Sarah Howell

Natural Resources Management and Environmental Sciences

This study was conducted to develop regional hydraulic geometry curves for the Santa Cruz Mountains that could be used in stream related and/or engineering projects. Data used to form these curves was collected from the USGS and by conducting stream geometry surveys. The resulting regional curves had high R² values ranging from .82 to .92. Compared to other regional curves in nearby areas, the Santa Cruz Mountains regional curve equations have higher exponents, meaning bankfull channel measurements increase at faster rates as drainage areas increases. Further measurements and analysis should be done before applying these curves to project sites.

Evaporation Estimation Of Rift Valley Lakes: Comparison Of Models, Assefa M. Melesse, Wossenu Abtew, Tibebe Dessalegne

Department of Earth and Environment

Evapotranspiration (ET) accounts for a substantial amount of the water flux in the arid and semi-arid regions of the World. Accurate estimation of ET has been a challenge for hydrologists, mainly because of the spatiotemporal variability of the environmental and physical parameters governing the latent heat flux. In addition, most available ET models depend on intensive meteorological information for ET estimation. Such data are not available at the desired spatial and temporal scales in less developed and remote parts of the world. This limitation has necessitated the development of simple models that are less data intensive and provide ET estimates …
