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 …

Pastoral Resources And Their Management In The Sandstone-Yalgoo-Paynes Find Area, Western Australia, A M E Van Vreeswyk, P. T. Godden

Agriculture reports

This report covers about 94,700 square kilometres of rangelands in the Sandstone-Yalgoo-Paynes Find area of Western Australia. The area lies within 27°S and 30°S latitudes, and 115°30'E and 120°E longitudes and includes the towns of Sandstone, Yalgoo and Paynes Find. The northern, southern, and eastern limits of the survey area are largely defined by the boundaries of the 1:250,000 scale series map sheets.The western limit is the boundary between the pastoral and agricultural area.

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 …

The Role Of Soil Test Information In Reducing Groundwater Pollution, Ronald A. Fleming, Richard M. Adams, David E. Ervin

Economics Faculty Publications and Presentations

Testing soils for nutrients is expected to improve groundwater quality. However, it is unknown whether soil testing will improve groundwater quality sufficiently to decrease the demand for direct regulation of agricultural practices. Focusing on an irrigated agricultural region in eastern Oregon, the economic and environmental aspects of soil testing are assessed using a spatially distributed, dynamic simulation model which links economic behavior with the physical processes that determine groundwater quality. Results indicate that soil testing of all fields increases farm profits and reduces groundwater nitrate concentration. However, the benefits are small in terms of potential improvements in groundwater quality.

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, …

An Inventory And Condition Survey Of The Sandstone-Yalgoo-Paynes Find Area, Western Australia, A L. Payne, A M E Van Vreeswyk, K A. Leighton, H J. Pringle, P Hennig

Technical Bulletins

The inventory and condition survey of the Sandstone-Yalgoo-Paynes Find area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1992 and 1993, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the area’s natural resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers about …

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 …
