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 Ecological Advantages Of Nuclear Power, Fred P. Bosselman Dec 2009

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 …

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 Dec 2009

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 …

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 …


Nest And Brood Survival And Habitat Selection Of Ring-Necked Pheasants And Greater Prairie-Chickens In Nebraska, Ty Matthews Dec 2009

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 …

Botti, Steve Brink, David Cleland, Larry Kapustka, Danny Lee, Valerie Luzadis, Laura Falk Mccarthy, Naureen Rana, Douglas B. Rideout, Matt Rollins, Peter Woodbury, Mike Zupko

United States Environmental Protection Agency: Publications

Ecological risk assessments typically are organized using the processes of planning (a discussion among managers, stakeholders, and analysts to clarify ecosystem management goals and assessment scope) and problem formulation (evaluation of existing information to generate hypotheses about adverse ecological effects, select assessment endpoints, and develop an analysis plan). These processes require modification to be applicable for integrated assessments that evaluate ecosystem management alternatives in terms of their ecological, economic, and social consequences.We present 8 questions that define the steps of a new process we term integrated problem formulation (IPF), and we illustrate the use of IPF through a retrospective case …

Development Of Regional Hydraulic Geometry Curves For The Santa Cruz Mountains, Sarah Howell Dec 2009

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.

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 Dec 2009

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 …


Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham Dec 2009

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham

Masters Theses & Specialist Projects

Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.

An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …

From The Bronx Into The Wild! My Adventurous Experience At The Bronx Zoo, Lauren Noll Dec 2009

From The Bronx Into The Wild! My Adventurous Experience At The Bronx Zoo, Lauren Noll

Student Theses 2001-2013

Many people defend zoos, claiming that they provide great opportunities in education, scientific research, and the overall preservation of wildlife worldwide. However, many people will take the opposing side, arguing that it is wrong to deprive animals of their natural habitats and lifestyles. One of the greatest controversies of our time pertains to the moral issues associated with keeping animals in captivity, such as in zoos and aquariums.


Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer Dec 2009

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 …

We currently know very little of the condition of marine and coastal natural resources in the Pilbara …


Analysis Of Mammoth Cave Pre-Park Communities, Matthew Brunt Dec 2009

Analysis Of Mammoth Cave Pre-Park Communities, Matthew Brunt

Masters Theses & Specialist Projects

Before the creation of Mammoth Cave National Park, this area was home to numerous communities, each with a sense of identity. To prepare for the creation of the National Park, all residents living within these communities were relocated, and many of these communities were lost to the passage of time. Today, public memory of these lost communities is being fostered by the descendents of the pre-park area.

Through the use of a Historical Geographic Information System, 1920 Edmonson County manuscript census data, and statistical analysis, the demographic composition of these lost communities was explored. This project not only brought to …

"All The Crises Reached A Concerted Crescendo" - The Arab Oil Embargo And Why The United States Was Unprepared For It, Jonathan D. Chilcote

Masters Theses & Specialist Projects

During the 2008 spike in oil prices, oil companies and government officials were brought under close scrutiny as many Americans began to question why prices were able to rise so quickly. Americans had become accustomed to living in an economy where cheap oil was the norm, and demanded answers when that situation changed. What most of them did not know is that they were repeating history and mimicking the response to the 1973 oil embargo. Just as in 2008, the United States faced a crisis in 1973 with which it was unprepared to effectively cope. This thesis analyzes the reasons …
