Construction Of An Environmental Quality Index For Public Health Research, Lynne C. Messer, Jyotsna S. Jagai, Kristen M. Rappazzo, Danelle T. Lobdell

Community Health Faculty Publications and Presentations

Background

A more comprehensive estimate of environmental quality would improve our understanding of the relationship between environmental conditions and human health. An environmental quality index (EQI) for all counties in the U.S. was developed.

Methods

The EQI was developed in four parts: domain identification; data source acquisition; variable construction; and data reduction. Five environmental domains (air, water, land, built and sociodemographic) were recognized. Within each domain, data sources were identified; each was temporally (years 2000–2005) and geographically (county) restricted. Variables were constructed for each domain and assessed for missingness, collinearity, and normality. Domain-specific data reduction was accomplished using principal components …

Spatial Analysis Of Post-Hurricane Katrina Thermal Pattern And Intensity In Greater New Orleans: Implications For Urban Heat Island Research, Aram P. Lief

LSU New Orleans Theses and Dissertations

In 2005, Hurricane Katrina’s diverse impacts on the Greater New Orleans area included damaged and destroyed trees, and other despoiled vegetation, which also increased the exposure of artificial and bare surfaces, known factors that contribute to the climatic phenomenon known as the urban heat island (UHI). This is an investigation of UHI in the aftermath of Hurricane Katrina, which entails the analysis of pre and post-hurricane Katrina thermal imagery of the study area, including changes to surface heat patterns and vegetative cover. Imagery from Landsat TM was used to show changes to the pattern and intensity of the UHI effect, …

Risky Business: Recommendations For The Insurance Industry To Contribute To Greater Disaster Risk Reduction And Climate Change Adaptation, Jessie G. Rountree

Master's Projects and Capstones

The private insurance industry is susceptible to increasing risk from climate change and can serve as a catalyst to change behavior to minimize loss. The research examined the current impact and future potential of the insurance industry to reduce both physical and financial risk. The insurance industry currently raises awareness, assigns an economic value to risk, advocates for climate change action, and takes measures to reduce physical risk through mitigation. As well, the industry has proven to be a critical influencer to encourage risk-adverse behavior and regulation. Recommendations to the industry to have a greater impact include: 1) pursue more …

Refining Dendrochronology To Evaluate The Relationship Between Age And Diameter For Dominant Riparian Trees In The Redwood Creek Watershed, Devin Barry

Master's Projects and Capstones

Methods of dendrochronology by means of incremental coring

have been refined in this study for specific use in northern

California riparian floodplains. Little information is available

on riparian dendrochronology because of the challenges of

analyzing riparian tree species. Three dominant tree species

(Alnus rubra, Umbellularia californica, Acer macrophyllum)

in the floodplain of Redwood Creek were evaluated for the

relationship between age and diameter at breast height (DBH)

using a least squares linear regression analysis. Through this

study, complications with analysis for the riparian tree species

led to a more thorough investigation as to enhancing core

quality and annual growth ring …

Investigating Telogenetic Karst Aquifer Processes And Evolution In South-Central Kentucky, U.S., Using High-Resolution Storm Hydrology And Geochemistry Monitoring, Nicholas Lawhon

Masters Theses & Specialist Projects

Recent studies have investigated the hydrological and geochemical characteristics of karst aquifers in different settings; however, telogenetic karst aquifer processes remain poorly understood. In south-central Kentucky, the iconic Lost River Cave and Valley represents a large, complex telogenetic karst drainage basin with a series of discharge points along a collapsed section of the cave. Two Campbell Scientific® CR1000 automated dataloggers were installed at Blue Hole Four, a primary discharge point of the Lost River Karst Aquifer (LRKA). These dataloggers recorded spring discharge, water temperature, specific conductance (SpC), and pH at ten-minute intervals from January to November, 2013. During the year, …

Gouldian Finch Breeding Surveys 2014: Ord-East Kimberley Expansion Project - Weaber Plain Development Area, Sarah R. Pryke, Nina Svedin

Irrigated Agricultural Development in the North

As part of the requirement for State approval under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the Gouldian Finch Management Plan (GFMP), a baseline assessment and on-going monitoring of the endangered Gouldian finch (Erythrura gouldiae) is required during the construction and operation of the Ord River Irrigation Area Weaber Plain Development Project in the eastern Kimberley, Western Australia. This report details the findings from surveys of Gouldian finches during their annual breeding season (Feb-May 2014).

Water-Use Restriction Information: Information Sharing Between Public Water Systems And State Government Offices, Christopher Carparelli

National Drought Mitigation Center: Faculty Publications

In many states there is an absence of communication between the state and local levels about many aspects of water resource management. This research examines the interaction between the state and local levels regarding water-use restrictions for public water systems (PWSs). This information is useful for state-level drought planning and mitigation through the assessment of drought impacts on public water supplies. Officials from five state-level entities that collect and disseminate local water-use restriction information were interviewed over the phone for this research. Each official was asked eleven questions about how and why their state collects and disseminates PWS water-use restriction …

Long-Term Effects Of Broiler Litter Application Rate On Runoff, Leaching, And Soil Respiration From A Captina Silt Loam, Richard Mcmullen

Graduate Theses and Dissertations

Producers in regions with intense broiler (Gallus gallus) production take advantage of the plant nutrients contained in broiler litter (BL) to enhance yields of forage grasses. However, application of BL to pasture lands in karst regions, like the Ozark Highlands, can potentially reduce water quality if BL-derived contaminants enter surface or groundwater via runoff or drainage. Additionally, BL applications stimulate carbon dioxide (CO2) release from the soil to the atmosphere and may contribute to global warming. The objectives of this study were to determine long-term trends in runoff and soil leachate water quality and to evaluate soil respiration …

Variable Bounds Analysis Of A Climate Model Using Software Verification Techniques, Peter Revesz, Robert Woodward

School of Computing: Conference and Workshop Papers

Software verification techniques often use some approximation method that identifies the limits of the possible range of values that variables in a computer program can take during execution. Current climate models are complex computer programs that are typically iterated time-step by time-step to predict the next value of the climate-related variables. Because these iterative methods are necessarily computed only for a fixed number of iterations, they are unable to answer many long-range questions that may be posed regarding climate change, for example, whether there are natural fluctuations or whether a tipping point is reached after which there is no return …

Estimating Nitrogen Fixation Rates, Importance, And Short-Term Efficiency In Small, Temperate Reservoirs Using Delta15n Techniques, Bryant Christopher Baker

Graduate Theses and Dissertations

Nitrogen (N2) fixation can give certain species of cyanobacteria a competitive advantage in lake and reservoir phytoplankton. These species of cyanobacteria, along with others that cannot fix N2, can form toxic compounds that impair water quality when present in high concentrations. N2 fixation rates may be substantial in small (< 1.0 km2), temperate reservoirs since these systems experience thermal stratification and often nitrogen (N) limitation throughout a substantial proportion of the year. However, the effects of N2 fixation on N cycling, alleviation of short-term N limitation, and water quality are not well-understood. A mesocosm experiment and ecosystem-scale observational study were conducted to 1) determine the efficiency of N2 fixation under varying N relative to phosphorus (P) supply, 2) examine the effects of N2 fixation on autotrophic biomass accumulation and microcystin production, and 3) measure N2 fixation rates and importance to autotrophic N demand and zooplankton N assimilation. Results of the mesocosm experiment indicated that N2 fixation was increased at low N:P supply under high P. However, N2 fixation was inefficient at alleviating N limitation when fixed N was the primary source of N. Additionally, microcystin production occurred only at high N:P supply when N2 fixation was low, indicating that reducing external N inputs may have a positive effect on water quality. Results of whole-reservoir determination of N2 fixation using seston δ15N natural abundances indicated that N2 fixation rates throughout the warm season were substantial and influenced by water temperature. Annual N2 fixation rates ranged from 2.2 - 6.6 g N m-2 yr-1, and contributed up to 19% of the annual autotrophic N demand. Zooplankton were assimilating fixed N in most of the study reservoirs, representing a possible mechanism of ecosystem fixed N retention. Collectively, these results suggest that N2 fixation plays a substantial role in N cycling in small, temperate reservoirs, but likely cannot alleviate short-term N limitation.
