In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein Feb 2001

In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Karst ground-water basin divides are generally depicted as two-dimensional lines on maps, but they are better considered as three-dimensional surfaces within the subsurface. Dye traces are necessary to map out these surfaces and to locate conduits inaccessible to cave surveyors, and are indispensable for understanding the geometry of the complex networks of flow paths through the aquifer. A key reason why the Mammoth Cave System is the world's longest known cave is that its passages extend over several major ground-water basins. The divides between these basins define the drainage system geometry and precise location of them is critical for understanding …

All-Inclusive List of Electronic Theses and Dissertations

The objective of this research is to develop cost-effect and accurate methods to identify optimal restorable drained wetland cropland sites. Landsat Thematic Mapper (TM) data analysis was used to identify the potential cropland candidate sites in the initial step. The result of digital TM data analysis shows that the overall classification accuracy in identifying classes of potential restoration candidate hydric soils is 86.7%. This accuracy shows that the TM data digital analysis is a cost-effective method for identifying poorly drained cropland hydric soils potentially suitable for wetland conversiOn. To support multi-factorial analysis in the final site screening, a Spatial Decision …


Comparative Analysis Of Thebes And Kirk Lithic Technology And Home Range Implications In Southwestern Indiana, Mark E. Cantin Aug 2000

Comparative Analysis Of Thebes And Kirk Lithic Technology And Home Range Implications In Southwestern Indiana, Mark E. Cantin

All-Inclusive List of Electronic Theses and Dissertations

Early Archaic populations are typically characterized as highly mobile forager groups with expansive home ranges, though little distinction is made between systems of penecontemporaneous groups. This thesis will investigate and compare home range size, technology, and material type and quality selection practices between two Early Archaic populations as manifested by Kirk and Thebes Cluster projectile points in a data set recovered from southwestern Indiana. The mechanisms behind and the relationships between chert selection and mobility will be shown as a complex feedback loop. As such, the role of curation, embeddedness, and risk management in technological organization and the potential influence …

Civilian Conservation Corps Rubble And Masonry Dams And Gully Morphology In Northeastern Iowa, Timothy Robert Beerman Jan 2000

Civilian Conservation Corps Rubble And Masonry Dams And Gully Morphology In Northeastern Iowa, Timothy Robert Beerman

Dissertations and Theses @ UNI

The Civilian Conservation Corps (CCC) was created in 1933 in an effort to help solve the problems associated with the lack of jobs for young men, the nations dwindling natural resources, and problems associated with soil erosion. The CCC's work in Iowa was primarily in the areas of reforestation and erosion control. Company 1749 of Cresco, Iowa stands out as an example of how the CCC worked to halt erosion. As a part of their erosion-control strategy, Company 1749 built a large number of rubble and masonry dams on gullies. These dams were designed to trap sediments and prevent further …


Intelligent Visualization And Automated Processing For Large Scale Geographic Information Systems, Yu Jiang Dec 1999

Intelligent Visualization And Automated Processing For Large Scale Geographic Information Systems, Yu Jiang

All-Inclusive List of Electronic Theses and Dissertations

This research focuses on developing a new output system that compacts maps in multiple projections into a single Geographic Information System (GIS) without visual errors, through constructing a discrete GIS database that is managed by a Relational Data Base Management System (RDBMS). Unlike in a traditional large GIS database, the data are "physically discrete but logically continuous." In a new discrete GIS database, every map keeps its individuality without a relationship to any other map, and the relationships among the maps are centrally managed by a RDBMS. A study site was chosen at the boundary of the state of Indiana …


Morphology Of Wetland Streams, Michael C. Jurmu Aug 1999

Morphology Of Wetland Streams, Michael C. Jurmu

All-Inclusive List of Electronic Theses and Dissertations

Recent understanding and concern with wetland environments has resulted in an increase in restoration and creation projects aimed at replicating these ecosystems. The unique characteristics within wetland environments result in different controls on streams traversing these areas, yet little research has been conducted to determine whether the morphology of these streams differs from streams in non-wetland, alluvial environments. Wetland streams from three different physiographic regions of the U.S. are compared to four morphological models and 12 additional features cited as typical in non-wetland streams. Analysis of this comparison will aid in determining whether wetland streams have differing morphology and which …


Analysis Of Lunar Basalt Flows In Oceanus Procellarum Using Clementine Data, Noel William Jackson Apr 1999

Analysis Of Lunar Basalt Flows In Oceanus Procellarum Using Clementine Data, Noel William Jackson

OES Theses and Dissertations

Remote sensing analyses of data set taken by Clementine in 1994 permit new observations about mineral distribution on the lunar surface, basalt flow stratigraphy, and thus the geologic evolution of the Moon. The northern section of Oceanus Procellarum contains numerous impact craters which penetrated the basalt and thus can be used as natural probes to estimate the number and thicknesses of flows.

I constructed a mosaic taken in three frequencies ( 415 nm, 750 nm, 950 nm), and a Ratio Image (750/415 = red, 750/950 = green, 415/750 = blue). On such an image, red indicates the iron-poor mature highland …

A Quantitative Analysis Of Interstitial Fluid-Chemistry And Limestone Dissolution Rates Within The Clastic Sediment Of A Karst Aquifer Conduit, Mammoth Cave, Kentucky, Kevin Vaughan Dec 1998

A Quantitative Analysis Of Interstitial Fluid-Chemistry And Limestone Dissolution Rates Within The Clastic Sediment Of A Karst Aquifer Conduit, Mammoth Cave, Kentucky, Kevin Vaughan

Masters Theses & Specialist Projects

Many active stream conduits within karst aquifers transport and deposit non-carbonate, clastic sediment. However, little is known about how these sediments impact conduit development and enlargement rates. For example, can dissolution take place at the sediment/bedrock interface beneath a flowing stream? If not, cavern enlargement might be dominated by flood conditions when the bare rock of the walls and ceiling are in contact with the dissolving fluids. An approach using limestone tablet weight loss experiments, along with water sampling and geochemical modeling, has been undertaken to understand the nature of fluid movement and chemistry with the sediment beneath an active …

Seasonal Effects On The Geochemical Evolution Of The Logsdon River, Mammoth Cave, Kentucky, Darlene Anthony Aug 1998

Seasonal Effects On The Geochemical Evolution Of The Logsdon River, Mammoth Cave, Kentucky, Darlene Anthony

Masters Theses & Specialist Projects

The following research describes the collection and evaluation of geochemical data from the Logsdon River, an open-flow conduit that drains a portion of the Turnhole Spring drainage basin within the Mammoth Cave karst aquifer of south-central Kentucky. This spatial survey of nearly 10 km of continuous base-level conduit included seasonal sampling of carbon dioxide partial pressures (Pco2)> dissolved ions, and saturation indices for calcite (SIcal). The highest PC02 values are found at the upstream site, closest to the Sinkhole Plain recharge area, which creates under-saturated conditions. Rapid outgassing of C02 into the cave atmosphere creates oversaturated conditions for several thousand …


Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer May 1998

Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer

Masters Theses & Specialist Projects

The dominant paradigms of the past decade involve the preservation of biodiversity through the use of landscape corridors and buffer zones, as well as the integration of economic growth through sustainable use. The International Biosphere Reserve (IBR) program, as defined in the Seville Strategy, encourages locations already involved in conservation to continue to protect biodiversity and foster harmonious relationships between humans and their environment through sustainable development. An excellent example of an IBR is the Mammoth Cave Area Biosphere Reserve (MCABR) in south-central Kentucky. In order to measure the significance of the implementation of the Seville Strategy in the MCABR, …

Description Of The Sections And Subsections Of The Interior Highlands Of Arkansas And Oklahoma, Thomas L. Foti, George A. Bukenhofer

Journal of the Arkansas Academy of Science

Sections and subsections of the Interior Highlands of Arkansas and Oklahoma are redefined, mapped and briefly summarized. The map was produced to support the Ozark- Ouachita Highlands Assessment (OOHA), being conducted by the USDA Forest Service. It revises the USDA Forest Service map "Ecological units of the eastern United States, first approximation" by Keys et al. (1995) and the earlier maps of the natural divisions of Arkansas (Foti, 1974; Foti, 1976; Pell, 1983) to reflect new knowledge and to achieve consistency with units recognized in Missouri. Four sections (natural divisions) are defined as opposed to the three of the previous …

Evaluation Of Selected Atmospheric Indices For The Prediction Of Thunderstorms At Omaha, Nebraska, Fred Ladehoff May 1997

Evaluation Of Selected Atmospheric Indices For The Prediction Of Thunderstorms At Omaha, Nebraska, Fred Ladehoff

Open Access Master's Theses (through 2010)

This study examines the values of five stability indices (the Showalter Index, the K Index, the Vertical Totals Index, the Cross Totals Index, and the Total Totals Index) for Omaha, Nebraska during the months of March through September, 1964 through 1973. Index means during thunderstorm periods and non-thunderstorm periods should show a distinct difference. Even though indices can be an important tool, it must be accentuated that indices should never be used as the sole factor in the prediction of thunderstorm or non-thunderstorm occurrences. This study shows that even at the highest skill scores, many mistakes would be made in …

Observation Of Shelfwater Overrunning The Southern Slope Sea, Ajoy Kumar Apr 1996

Observation Of Shelfwater Overrunning The Southern Slope Sea, Ajoy Kumar

OES Theses and Dissertations

Analyses of two years (1992 and 1993) of high resolution (1.47 km2) sea surface temperature satellite images of the southern Mid-Atlantic Bight (MAB), showed that unusually extensive overhang of shelf water occurs episodically, and coherently over along shelf distances of several hundred kilometers. These episodes are dubbed overrunning of the Slope Sea by shelf water. The overrunning volume has a "face" and a "back" (southern and northern limit). It transports substantial quantities of shelf water southward, and does not retreat onto the shelf, but eventually joins the western edge of the Gulf Stream in the vicinity of Chesapeake …

Hydrogeological And Hydrochemical Characterization Of The Matozinhos-Pedro Leopoldo Karst, Brazil, Augusto Auler Nov 1994

Hydrogeological And Hydrochemical Characterization Of The Matozinhos-Pedro Leopoldo Karst, Brazil, Augusto Auler

Masters Theses & Specialist Projects

The Matozinhos-Pedro Leopoldo limestone area is a tropical karst located near the metropolis of Belo Horizonte, East Central Brazil, in an area undergoing rapid urbanization and land degradation. Qualitative dye tracing experiments have determined the groundwater routes and catchment areas in the two major drainage basins in the area, Samambaia Basin and Palmeiras-Mocambo Basin. Other drainage basins were identified, but not traced due to the absence of related swallets. Fluorescein and optical brightener had a poor performance as tracers under tropical climate. Dilution due to the existance of lakes at some swallets prevented some dye traces. The water that flows …
