Dispersion Of Ammonia From Concentrated Animal Feeding Operations, Austin D. Wardall Oct 2016

Dispersion Of Ammonia From Concentrated Animal Feeding Operations, Austin D. Wardall

Masters Theses & Specialist Projects

The purpose of this research is to investigate the dispersion of ammonia (NH3) from three Concentrated Animal Feeding Operations (CAFOs) in western Kentucky, as well as to investigate the Weather Research and Forecasting – Chemistry (WRF-Chem) model’s sensitivity response to initial NH3 concentrations under both wet conditions (significant precipitation) and dry conditions (no precipitation). As expected, pollutant concentrations generally were significantly higher near their points of origin and generally declined away from the sources. Contrary to expectations, ammonia tended to rise through the planetary boundary layer (PBL) regardless of atmospheric conditions. Results showed modeled NH3 pollution levels at the surface …

Icelandic Fisheries: Scenario Planning For Climate Change, Tara Sorrels Sep 2016

Icelandic Fisheries: Scenario Planning For Climate Change, Tara Sorrels

Mahurin Honors College Capstone Experience/Thesis Projects

This study aimed to develop an understanding of how a scenario planning process could be used to assist businesses to adapt to climate change. The focus of this study was on the Icelandic fishing industry since Iceland is experiencing firsthand climate change impacts. Mitigation strategies are the main focus in climate change research, but this study focused on a possible adaptation method that requires changing management practices in order to reduce the impact of climate change on the economy. Tours of Icelandic fisheries and interviews with individuals within the Icelandic fishing industry were conducted to assess the current adaptive capacity …

Karst Landscape Influence On The Planetary Boundary Layer Atmosphere, Zachary S. Sullivan Jul 2016

Karst Landscape Influence On The Planetary Boundary Layer Atmosphere, Zachary S. Sullivan

Masters Theses & Specialist Projects

Karst landscapes cover approximately 20% of the ice-free land area worldwide. The soluble nature of the bedrock within a karst landscape allows for the formation of caverns, joints, fissures, sinkholes, and underground streams, which affect the hydrological behavior of the region. Currently, the Noah Land-Surface Model (Noah- LSM), coupled with the Weather Research and Forecasting (WRF) model, does not provide a representation of the physical behavior of a karst terrain. Previous research has attempted to model karst behavior through soil moisture and land cover/land use changes to determine the influence this unique landscape may have on atmospheric phenomenon. This highlights …

The Influence Of Tropical Cyclones On Droughts And Warm Season Precipitation In Tennessee And Kentucky, Lamar S. Coats Apr 2016

The Influence Of Tropical Cyclones On Droughts And Warm Season Precipitation In Tennessee And Kentucky, Lamar S. Coats

Masters Theses & Specialist Projects

The Southeast United States during summer and fall is often affected by droughts and tropical cyclones. Both phenomena rank among the most expensive of natural hazards, although droughts are not as feared by the public as hurricanes. When a tropical cyclone causes a pendulum swing from drought to wet conditions, it is known as a “drought-busting tropical cyclone.” The majority of the research related to drought busting tropical cyclones investigates only the storms during their tropical cyclone phase, which covers the southeastern states that have boundaries adjacent to the Atlantic Ocean. An unanswered question from this literature is whether or …

Advancing Methods To Measure The Atmospheric Co2 Sink From Carbonate Rock Weathering, Devon Salley Mr. Apr 2016

Advancing Methods To Measure The Atmospheric Co2 Sink From Carbonate Rock Weathering, Devon Salley Mr.

Masters Theses & Specialist Projects

With rising atmospheric CO2 concentrations, a detailed understanding of processes that impact atmospheric CO2 fluxes is required. While a sink of atmospheric carbon from the continents to the ocean from carbonate mineral weathering is, to some degree, offset by carbonate mineral precipitation in the oceans, efforts are underway to make direct measurements of these fluxes. Measurement of the continental sink has two parts: 1) measurement of the dissolved inorganic carbon (DIC) flux leaving a river basin, and 2) partitioning the inorganic carbon flux between the amount removed from the atmosphere and the portion from the bedrock. This study attempted to …

Technique Comparisons For Estimating Fragility Analysis In The Central Mid-West, Kimberly Ann Walker Apr 2016

Technique Comparisons For Estimating Fragility Analysis In The Central Mid-West, Kimberly Ann Walker

Masters Theses & Specialist Projects

Climate change studies and examinations of increasing sea levels and temperatures show storm intensity and frequency are increasing. As these storms are increasing in intensity and frequency, the effects of these storms must be monitored to determine the probable damages or impacts to critical infrastructure [2, 35]. These storms suddenly create new demands and requirements upon already stressed critical infrastructure sectors [1]. A combined and interdisciplinary effort must be made to identify these stresses and to mitigate any failures. This effort is needed so that the 21st Century Smart Grid is robust and resilient enough to ensure that the grid …
