Acid Rain: The Effects, Torrey Mortimer Nov 2009

Acid Rain: The Effects, Torrey Mortimer

Social Sciences

In a world experiencing increasing population, urbanization, and developing nations looking to compete on a global market with post-industrial nations, the effects of acid precipitation require greater consideration. As the world’s energy demand rises, and with the cheapest and most abundant source of energy being coal, the occurrence of acid precipitation is on the rise.

The goal of my project is to research and report on the effects of acid deposition on humans, animals and the environment that surrounds them. When I have completed my project, I hope to be able to explain the impacts that acid deposition has on …


A River Transformed: Historic Geomorphic Changes Of The Lower Rio Grande In The Big Bend Region Of Texas, Chihuahua, And Coahuila, David James Dean May 2009

A River Transformed: Historic Geomorphic Changes Of The Lower Rio Grande In The Big Bend Region Of Texas, Chihuahua, And Coahuila, David James Dean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the last century, the construction and management of large dams and stream-flow diversions, and periodic drought have resulted in significant declines in stream flow of the lower Rio Grande in the Big Bend region. Reductions in mean annual flow and peak discharge have resulted in channel narrowing by the formation of vertically accreting inset floodplains. Narrowing has been temporarily interrupted by infrequent large dam releases greater than 1000 m3/s that have temporarily widened the channel; however, after each of these events, narrowing has resumed. Prior to 1942, floods of this magnitude occurred approximately once every 4 years …


Is It Windy Enough For You? The Potential For Wind Energy To Generate Electricity, Income, And Energy Security In Rural East-Central Nebraska, Roy M. Zach Apr 2009

Is It Windy Enough For You? The Potential For Wind Energy To Generate Electricity, Income, And Energy Security In Rural East-Central Nebraska, Roy M. Zach

Student Work

Citizens living in the Columbus, Nebraska area once met all of their local electric power needs via the Columbus and Monroe hydropower facilities. Today, this area imports significant quantities of electricity via high voltage power transmission lines, thereby creating dependencies on areas far away. The purpose of this study was to examine the potential for wind power within this area of Nebraska—in order to generate electricity, income, and energy security at a more local level. A thorough analysis of the local wind resource, and its comparison to the local electric power demand, demonstrates the economic feasibility of producing electricity from …


Exploitation Of Geographic Information Systems For Vehicular Destination Prediction, Richard T. Muster Mar 2009

Exploitation Of Geographic Information Systems For Vehicular Destination Prediction, Richard T. Muster

Theses and Dissertations

Much of the recent successes in the Iraqi theater have been achieved with the aid of technology so advanced that celebrated journalist Bob Woodward recently compared it to the Manhattan Project of WWII. Intelligence, Surveillance, and Reconnaissance (ISR) platforms have emerged as the rising star of Air Force operational capabilities as they are enablers in the quest to track and disrupt terrorist and insurgent forces. This thesis argues that ISR systems have been severely under-exploited. The proposals herein seek to improve the machine-human interface of current ISR systems such that a predictive battle-space awareness may be achieved, leading to shorter …


A Gis Analysis On Possible Photovoltaic Cell Use For Energy Reduction During Peak Hours In Huntington, West Virginia, James Eric Tadlock Jan 2009

A Gis Analysis On Possible Photovoltaic Cell Use For Energy Reduction During Peak Hours In Huntington, West Virginia, James Eric Tadlock

Theses, Dissertations and Capstones

Solar panels are one of the fastest growing renewable energy technologies. This study aims to identify to what extent roof-mounted solar panels can reduce the need of power provided by Appalachian Power Company. Data from the Reliability First Corporation was employed to determine the individual average household power usage. Three study areas in Huntington, West Virginia, were selected to determine if solar panels could be implemented. Roofs in the study areas were digitized to calculate the available area. Based on the average household usage, four different sized photovoltaic systems were determined. Potential power production was computed to identify any offset …


Modeled Red Spruce Distribution Response To Climatic Change In Monongahela National Forest, James Michael Stanton Jan 2009

Modeled Red Spruce Distribution Response To Climatic Change In Monongahela National Forest, James Michael Stanton

Theses, Dissertations and Capstones

In Monongahela National Forest of West Virginia, red spruce grows in high-elevation island ecosystems that are particularly sensitive to changes in climatic conditions. The ecological niche modeling application Maxent was used to project the distribution response of red spruce to climatic change for the purposes of conservation planning. Red spruce distribution data was acquired from the United States Forest Service. Three sets of nineteen bioclimatic variables, corresponding to present, 2050, and 2080 conditions, were derived from 1961-1990 monthly temperature and precipitation means and the IPCC A2 emissions scenario of HadCM3. The modeling revealed rapidly diminishing red spruce habitat suitability from …


Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover Jan 2009

Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover

Dissertations, Theses, and Masters Projects

A quantification of the role that barrier island overwash plays in the evolution of Onslow Beach, a barrier island located on Marine Corps Base Camp Lejeune, North Carolina, is presented. Ground-penetrating radar (GPR) and sediment vibracores provide an estimate of the relevant-sand prism above a silty/peat contact underlying the island. The average thickness from the surface, as determined from lidar, to this geologically-defined base, is less than 1 m and equates a total volume of approximately 1.8 ± 1.1 × 106 m3 over the 4.8 km stretch of Onslow Beach from 1 km north of the New River Inlet to …
