Karst Hydrogeology Of The Haney Limestone, South-Central Kentucky, Sarah Marie Arpin
Masters Theses & Specialist Projects
South-central Kentucky has one of the world’s most intensively studied karst
areas, with most work focusing on the Mammoth Cave System and related caves and aquifers. However, slightly higher in the stratigraphic section than Mammoth Cave, the Haney Limestone is a locally important but less well studied carbonate aquifer. This research provides the most comprehensive synthesis to date of the karst hydrogeology of the Haney Limestone of south-central Kentucky, focusing on the distribution and controls on cave and karst features developed within. In contrast to drainage systems within the major limestones below, joints are the most dominant control on ...

Smart Dispatch Methods, Hannah K. Panno
Social Sciences
My senior project will be focused on smart dispatch methods for CAL FIRE. Currently the level of dispatch including how many personnel and how much equipment such as fire engines, water tanks, dozers, and aircrafts that are sent to a fire is based on subjectivity rather than science. A reliable dispatch system based on Fire Family Plus software needs to be implemented in San Luis Obispo County. A reliable dispatch should be grounded on the prominent elements of fire progression i.e. fuels, topography, and climatology. These fire catalysts will be applied and considered based on unique climate regions of ...

Proximal Sensing As A Means Of Characterizing Phragmites Australis, Travis Yeik
Theses and Dissertations in Geography
Phragmites australis is an invasive wetland weed found throughout much of the United States. Documenting and mapping the growth and spread of this emergent macrophyte can be an important step in developing and implementing successful management strategies. Characterizing the phenology of a vegetation species with a sensor capable of hyperspectral resolution, positioned at close proximity to the canopy of interest, is often a first step necessary for understanding the basic species-specific reflectance patterns, and for quantifying the manner in which light interacts with the plants comprising particular communities. Spectral data over a P. australis canopy were collected during 22 field ...

The Periglacial Landscape Of Utopia Planitia; Geologic Evidence For Recent Climate Change On Mars., Mary C. Kerrigan
Electronic Thesis and Dissertation Repository
The northern plains of Utopia Planitia, Mars, hosts an abundance of potential periglacial landforms including scalloped depressions, gullies, and polygon networks. This research was undertaken to investigate the distribution and stratigraphy of scalloped depressions in Utopia Planitia and to reconstruct the past environment in which this periglacial landscape formed. To that end, a revised geologic map of the region has been produced. We define, for the first time, a new Periglacial Unit, the youngest geologic unit in Utopia Planitia. We have also developed a model for the formation and evolution of the periglacial landscape examined by assessing the use of ...
Teleconnective Influences On The Strength Of Post-Tropical Cyclones, Jeremy Young Western Kentucky University
Teleconnective Influences On The Strength Of Post-Tropical Cyclones, Jeremy Young
Masters Theses & Specialist Projects
Over the 1951-2009 time period, 47% of all tropical systems in the Atlantic Basin transitioned to post-tropical storms. These storms are capable of producing hurricaneforce winds, torrential, flooding rains and storm surge that floods coastal areas. This study adds to previous climatological work by completing a case-study of Hurricane Ike (2008) and examining how teleconnections such as the El Niño Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), the Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) contribute to the strength of a transitioning post-tropical storm. T-tests performed show strong statistical relationships between an increase (decrease) in post-tropical storm ...
Examining Land Use/Land Cover Change And Potential Causal Factors In The Context Of Climate Change In Sagarmatha National Park, Nepal, Kamal Humagain Western Kentucky University
Examining Land Use/Land Cover Change And Potential Causal Factors In The Context Of Climate Change In Sagarmatha National Park, Nepal, Kamal Humagain
Masters Theses & Specialist Projects
In the context of growing tourism and global warming, the fragile landscape of the Himalayas is under immense pressure because of rapid land cover changes in developing countries like Nepal. Remotely sensed data combined with ethnographic knowledge are useful tools for studying such changes. The quantitative change can be measured analyzing satellite images whereas local people’s perceptions provide supportive information. To measure such changes in Sagarmatha National Park of Nepal, Multispectral Scanner (MSS) and Thematic Mapper (TM) images since 1972 were used. Normalized Difference Vegetation Index (NDVI) was calculated for different elevation classes and land cover types. These measurements ...
Multi-Temporal Analysis Of Crop Biomass Using Selected Environmental Variables And Remote Sensing Derived Indices, Nwakaku M. Ajaere University of Nebraska - Lincoln
Multi-Temporal Analysis Of Crop Biomass Using Selected Environmental Variables And Remote Sensing Derived Indices, Nwakaku M. Ajaere
Theses and Dissertations in Geography
Measuring biomass in crops is important for yield prediction, nutrient management and analysis of carbon sequestration. Studying crop phenology via biomass can also provide insight into not only the state of the ecosystem but also environmental factors which may affect crop growth. Remote sensing techniques, as an alternative to traditional in-situ sampling methods for biomass assessment, provide potentially more efficient data acquisition and cost-effective procedures. Numerous vegetation indices (VI) have been developed which use spectral reflectance data to measure plant biophysical characteristics. The first objective of this research was to examine the correlation between crop biomass and selected environmental variables ...
Fire Regimes Of Lower-Elevation Forests In Great Smoky Mountains National Park, Tennessee, U.S.A., Lisa Battaile LaForest

Fire Regimes Of Lower-Elevation Forests In Great Smoky Mountains National Park, Tennessee, U.S.A., Lisa Battaile Laforest
Doctoral Dissertations
Disturbance is a natural part of any forest ecosystem. When disturbance regimes are altered, the forest stands will reflect those changes. Southern Appalachian xeric pine-oak woodlands are one forest type that has experienced such change, primarily in the form of fire suppression. The western side of Great Smoky Mountains National Park contains stands of large trees that escaped earlier intensive logging, show evidence of past fire, and provide an ideal setting for reconstructing stand histories. For three lower-elevation (ca. 500 m ASL) study sites, I used crossdated yellow pine tree-ring chronologies and records from cross-sections taken from living and dead ...
Diatoms In Castor Lake (North-Central Washington, Usa) – Proxies Of Climate And Hydrologic Variation, Kelly D. Hollingshead Western University
Diatoms In Castor Lake (North-Central Washington, Usa) – Proxies Of Climate And Hydrologic Variation, Kelly D. Hollingshead
Electronic Thesis and Dissertation Repository
This research provides a high temporal resolution (1 sample / 2-3 years) record of hydrologic variation for the last 2,000 years using a lake sediment record from Castor Lake, a closed-basin system in Washington, USA. The core was dated using 137Cs, 14C, and tephrochronology. Approximately 600 diatoms were identified and enumerated in 198 samples from a Castor Lake freeze core and Livingstone-piston core. A diatom-inference model for salinity was applied to reconstruct fossil diatom salinity. Diatom-inferred salinity for the last century tracked Palmer Drought Severity Index, indicating diatom community composition tracks effective moisture and can be used to ...
Using Landscape Pattern Metrics To Characterize Ecoregions, Martha Isabel Posada Posada University of Nebraska - Lincoln
Using Landscape Pattern Metrics To Characterize Ecoregions, Martha Isabel Posada Posada
Dissertations & Theses in Natural Resources
Ecological regions, or ecoregions, are areas that exhibit “relative homogeneity in ecosystems”. The principal objective of this research was to determine if and how landscape structure (quantified by landscape pattern metrics) may be related to ecoregions defined using Omernik’s approach to ecoregionalization. Nine key landscape pattern metrics (number or LULC classes and the proportion of each class, number of patches, mean patch size and area-weighted fractal dimension, perimeter-area fractal dimension, contagion, mean Euclidean nearest neighbor distance and interspersion and juxtaposition index) where used to asses landscape structure in a sample of 26 Omernik Level III ecoregions located in the ...

Government Documents On Rare Earth Minerals, Bert Chapman
Libraries Faculty and Staff Presentations
Rare earth minerals contain unique chemical and physical properties such as lanthanum, are found in small concentrations, need extensive precise processes to separate, and are critical components of modern technologies such as laser guidance systems, personal electronics such as Blackberries, and satellites. The U.S. has some rare earth resources, but is heavily dependent on access to them from from Afghanistan, Bolivia, and China. Losing access to these resources would have significant economic, military, and political implications. This presentation will highlight government information resources on rare earth minerals from agencies such as the Department of Energy (DOE), Department of Defense ...
Dealing With Culturally Sensitive Areas In Industrial Project Design, Alan Ehrlich Western University
Dealing With Culturally Sensitive Areas In Industrial Project Design, Alan Ehrlich
The International Indigenous Policy Journal
Potential cultural impacts from proposed industrial developments can affect culturally sensitive areas that are important to Aboriginal peoples. These cultural impacts are important for legal, political, and moral reasons and can have a major influence on project approval or rejection during environmental impact assessment. It is in the interest of developers to identify and consider potential impacts on culturally sensitive areas early in the project proposal process in order to design projects that minimize or avoid these impacts. A key strategy is to engage communities effectively in the process. Different types of mitigation measures, including off-site cultural mitigation, may be ...
