Projecting The Economic Impact Of The Fayetteville Shale Play For 2008-2012, Katherine A. Deck
Projecting The Economic Impact Of The Fayetteville Shale Play For 2008-2012, Katherine A. Deck
Publications and Presentations
In 2006, the Center for Business and Economic Research released an economic impact study of the newly developing natural gas industry related to the Fayetteville Shale. The Fayetteville Shale is an unconventional gas reservoir located on the Arkansas side of the Arkoma Basin, ranging in thickness from 50 to 325 feet and ranging in depth from 1,500 to 6,500 feet. That study concluded that from 2005 to 2008, economic output of over $5.5 billion and 9,683 jobs would be generated as a result of investments in the Fayetteville Shale. Those estimates were based on the best information available when the …
Runoff Using A Combined Geographic Information System And Curve Number Approach, Keshia M. Koehn
Runoff Using A Combined Geographic Information System And Curve Number Approach, Keshia M. Koehn
Inquiry: The University of Arkansas Undergraduate Research Journal
Stormwater runoff can transport nutrients, sediments, chemicals, and pathogens to surface water bodies. Managing runoff is crucial to preserving water quality in rapidly developing urban watersheds like Northwest Arkansas. A watershed containing much of the University of Arkansas campus was identified as the target area for this study because stormwater from this location drains into the West Fork of the White River, designated as an impaired water body due to siltation. The project objective was to develop a methodology to test existing stormwater drainage infrastructure, identify potential areas of improvement, and estimate potentially contaminated runoff by combining two widely used …

This study projects the general economic impact from exploration and development activities related to the Fayetteville Shale. The Fayetteville Shale is an unconventional gas reservoir located on the Arkansas side of the Arkoma Basin, ranging in thickness from 50 to 325 feet and ranging in depth from 1,500 to 6,500 feet. The Fayetteville Shale is aerially extensive and may be present across numerous counties in central and eastern Arkansas, including the counties of Cleburne, Conway, Faulkner, Independence, Johnson, St. Francis, Prairie, Van Buren, White, and Woodruff.
Laboratory-Scale Evaluation Of Incandescent And Compact Florescent Lamps For Poultry House Lighting, Leanne Gabriel, Donald M. Johnson
Laboratory-Scale Evaluation Of Incandescent And Compact Florescent Lamps For Poultry House Lighting, Leanne Gabriel, Donald M. Johnson
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
This laboratory-scale study compared 1000- and 2000-h rated 60W incandescent lamps and 6000-h rated 60W-equivalent compact florescent lamps over 6000 h of simulated broiler-house operation. The four original 1000-h incandescent lamps were replaced 22 times and the four 2000-h incandescent lamps were replaced 14 times. None of the four compact florescent lamps failed during the 6000-h experiment, although one was broken due to human error. Both types of incandescent lamps had significantly higher (p < .0001) mean illuminance (lx) than did the compact florescent lamps. The compact florescent lamps used significantly less (p < .0001) power (W) and had significantly higher (p < .0001) efficiency (lx/W) than the incandescent lamps. Despite a higher initial purchase price, the total cost (purchase + replacement + electrical) of operating compact florescent lamps was approximately 36% lower than the total cost of operating either type of incandescent lamp over the 6000 h period. The results of this study indicate that even at a least-cost price for electricity ($0.04/kW/h), growers can reduce total broilerhouse lighting costs by replacing incandescent lamps with compact florescent lamps.
Water Resources Issues In The Arkansas Delta, Kenneth F. Steele
Water Resources Issues In The Arkansas Delta, Kenneth F. Steele
Technical Reports
Despite its location in Northwest Arkansas, the Arkansas Water Resources Center (AWRC) is active state-wide. This fact is underscored by the focus of the Center’s session on "Water Resource Issues in the Arkansas Delta" during its recent joint Conference. Water issues in the Delta include declining water tables, salt water intrusion, and water quality (especially suspended sediment, nitrate and pesticides). Presented papers focused on best management practices for cotton production, economics of on-farm reservoirs, chloride content of irrigation water, and landowner education. The AWRC short course was an excellent one on chemical transport in the vadose zone by Dr. Glenn …
Quality Of Surface And Ground Water And Best Management Practices, Kenneth F. Steele
Quality Of Surface And Ground Water And Best Management Practices, Kenneth F. Steele
Technical Reports
Arkansas is fortunate to have outstanding water resources, especially in terms of water quality. However, this is not to say that there are no problems. The Arkansas Water Resources Center (AWRC) in cooperation with other state and federal agencies is characterizing our water resources and providing data important to the wise use of these resources. One wise use of our water resources is to mitigate the impact of non-point sources of pollution on water quality through the use of best management practices. These proceedings address not only the characterization of the quality of ground and surface water but also address …
Diversity Of Arkansas Water Resources Research, Kenneth F. Steele
Diversity Of Arkansas Water Resources Research, Kenneth F. Steele
Technical Reports
In order to understand, protect, and manage our water resources effectively knowledge is required from many diverse areas of science, engineering, economics, and sociology. These proceedings of the conference on the Diversity of Arkansas Water Resources Research reflect this need and demonstrate how researchers in the state are responding to water issues and problems in Arkansas. The papers in these proceedings are representative of the research in Arkansas, but are only a sample of the work being conducted by universities and government agencies in Arkansas. We are grateful that Arkansas has the expertise available to provide the information necessary to …
Water Resources Studies Along The Arkansas-Oklahoma Border, Kenneth F. Steele
Water Resources Studies Along The Arkansas-Oklahoma Border, Kenneth F. Steele
Technical Reports
The watershed approach to water resource issues recently has been re-discovered. Scientists and managers recognize the need to consider the entire watershed when delineating and solving today's water resource problems. A simple example is the effect that streams have on the ultimate "health" of a reservoir. Although technically the term watershed should be used only in reference to surface water, the importance of ground water is included in the watershed approach to problems. In recognition that we all "live upstream and downstream," the Arkansas Water Resources Center and the Oklahoma Water Resources Institute sponsored a conference titled "Water Resource Studies …

Gis Characterization Of Beaver Watershed, H. D. Scott, J. M. Mckimmey
Technical Reports
Beaver Reservoir watershed is located in Northwest Arkansas including portions of Madison, Washington, Benton, Carroll, Franklin and Crawford counties. This watershed is important to the Northwest Arkansas region because it supplies most of the drinking water for the major towns and cities, and several rural water systems. The watershed consists of 308,971 ha with elevations ranging from approximately 341 m to 731 m above mean sea level. It includes the Springfield Plateau and the Boston Mountains provinces within the Ozark Plateau physiographic region. There are approximately 581 km of streams, 532 km of shore line, and 3712 km of roads …
