Investigating Historical and Contemporary Land Cover Effects on Macroinvertebrate Communities and Water Quality of Virginia Piedmont Streams
(Virginia Tech, 2014-09-17)
I investigated the relationships between historical and contemporary land cover and macroinvertebrate communities, water quality, and nutrient levels in 10 streams in a historically agricultural region of the Virginia ...
A Dendrochronological Analysis of Vegetation Change and Climate History in Two Southern Appalachian Balds, Craggy Gardens and Big Bald, NC
(Virginia Tech, 2007-04-06)
In the southern Appalachians, unforested openings known as balds persist on or near mountain peaks. These high elevation openings support a variety of unusual biota and are considered globally rare as a result of their ...
Terrain and Landcover Effects of the Southern Appalachian Mountains on the Low-Level Rotational Wind Fields of Supercell Thunderstorms
(Virginia Tech, 2012-04-30)
That tornadoes cannot occur in mountains due to disruptive influences of the complex terrain is a common misperception. Multiple tornadoes occur each year in mountainous environments, including the Appalachian Mountains. ...
A Model to Convert Airport Geographic and Geometric Information into a Node-Link Network
(Virginia Tech, 2015-01-17)
An airport node-link network model is an important input for most airport simulation models. Developing, maintaining and updating detailed airport surface node-link models require significant work. A model to convert airport ...
Positional accuracy in a natural resource database: comparison of a single-photo resection versus affine registration
(Virginia Tech, 1995-04-05)
Effects of Stream Order and Data Resolution on Sinuosity Using GIS
(Virginia Tech, 2008-04-29)
This research focuses on estimation and analysis of stream sinuosity using GIS. Fifty-five streams including 13 streams of order 0, 17 streams of order 1, 15 streams of order 2 and 10 streams of order 3 in Virginia were ...
The Benefits of EcoRouting for a Parallel Plug-In Hybrid Camaro
(Virginia Tech, 2017-07-14)
EcoRouting refers to the determination of a route that minimizes vehicle energy consumption compared to traditional routing methods, which usually attempt to minimize travel time. EcoRoutes typically increase travel time ...
Influences of land use on the structure and function of headwater streams: A multiple scale analysis
(Virginia Tech, 2000-07-21)
The structure and function of stream ecosystems may be strongly influenced by land-use practices within watersheds. The magnitude of land-use impacts may depend upon the spatial arrangement of development in watersheds. ...
A GIS Model for Minefield Area Prediction: The Minefield Likelihood Procedure
(Virginia Tech, 2002-11-27)
Existing minefields left over from previous conflicts pose a grave threat to humanitarian relief operations, domestic everyday life, and future military operations. The remaining minefields in Afghanistan, from the decade ...
U/Pb Zircon Ages of Plutons from the Central Appalachians and GIS-Based Assessment of Plutons with Comments on Their Regional Tectonic Significance
(Virginia Tech, 2001-09-28)
The rocks of the Appalachian orogen are world-class examples of collisional and extensional tectonics, where multiple episodes of mountain building and rifting from the pre-Cambrian to the present are preserved in the ...
