Research & Economic Development

The Center is equipped with a geographic information system (GIS) computer laboratory that enhances the analysis of groundwater and surface-water quality and quantity, hydrology and watershed analysis, networking and three-dimensional analysis, and integrated stream assessment and aquatic habitat analysis. The Center also provides an ARCGIS software suite that allows for the realistic representation of naturally and humanly developed spatial features for assessment and planning applications.

The Center's GIS computer laboratory supports the research and educational activities of faculty and graduate students. The lab is equipped with a network of Windows workstations with connectivity to various color printers, a plotter, and scanners. The GIS lab maintains the large spatial databases and models developed from research. Recently, the Center became home to the TNPORWS program, serving out the OASIS model, which provides water modeling software that incorporates river basin management, drought planning, water supply planning, hydropower generation, and conflict resolution.

The Center's GIS lab and resources are overseen by Yvette Clark, Research and Development Engineer.

Yvette Clark has 27 years' ArcGIS software, geodatabase design, model building and programming experience. She is also experienced in integrating water quality and quantity models with ArcGIS for watershed-based decision management and planning. Her skills include developing turnkey systems, including hardware, software and integrated models, to meet funding agency project requirements. Clark has worked with students and faculty to convert spatial data for educational and research endeavors and has also acquired skills in installing and configuring systems for department and research interests.


  • Through multiple grants with the Tennessee Department of Economic and Community Development, Clark earned more than 1.5 million dollars in external funding over a 17-year period.
  • She helped produce annotated bibliographies, including GIS information and water quality data, for the Duck River, Emory River and Missouri River watersheds. These projects can be found at
  • Clark developed materials to teach the use of the OASIS water modeling software to state stakeholders. OASIS model applications include river basin management, drought planning, water supply planning, hydropower generation, and conflict resolution.
  • She as taught courses for the Governor's School for Emerging Technology, the Department of Chemical Engineering, and the Department of Civil Engineering.
  • Clark has published six refereed articles, two non-refereed articles, and four technical reports. She has made 12 professional presentations and produced two educational guides.
  • Clark has served the state and university through several grant-funded projects that benefit the environment through hydrologic modeling and other GIS-related techniques.
