THESES AND DISSERTATIONS AND GRADUATE WORK



Habersack, Matt; Virginia Tech, Ph.D (T. A. Dillaha): Research Problem: Characterization wildlife bacterial loadings to streams in Southwestern Virginia. The goal of this research is to model and predict the loadings and fate of fecal coliform (FC) and Escherichia coli (EC) bacteria from raccoons (Procyon lotor), muskrats(Ondatra zibethicus), and beavers(Castor canadensis) in streams in Southwest Virginia for TMDL development purposes. This will be accomplished by:

1. Quantifying fecal production rates and spatial distribution of fecal deposits

2. FC and EC concentrations of scat

3. In-situ die-off rates for bacteria isolates originating from the three species investigated



Hendricks, G. S. 2003. Performance evaluation of two hydrologic/water quality models on beef pastures at Buck Island Ranch. Masters Thesis. Agricultural and Biological Engineering Department, University of Florida, Gainesville. 124 p.



Henry, Leigh-Anne; MS, Virginia Tech (T.A. Dillaha): Research Question: How do fecal indicator bacteria partition between sediment-attached and free phases. Research objectives

1. Investigate the accuracy and reliability of different methods used to differentiate between free and soil-adsorbed bacteria.

a. Identify candidate methods.

b. Evaluate the accuracy and precision of identified methods using bacterial samples of known composition to determine each of the tests? accuracy and repeatability.

c. Select the best methods for different bacteria and sample matrices.

2. Use the selected methods to develop isotherm equations describing the partitioning between free and soil-attached bacteria for E. coli bacteria.

3. Determine the applicability of these isotherm equations using runoff samples obtained from a rainfall simulator experiment.

Wagner, Rachel; MS, Virginia Tech (T. A. Dillaha): Research Question: How do the different methods of developing and implementing benthic TMDLs differ in terms of the stressor reductions required to eliminate the benthic impairment? Methods being investigated include:

1. Alternative reference watersheds with the GWLF model (Stroubles Creek TMDL).

2. Regression model approach without reference watershed.

3. Reference watershed with different water quality models (SWAT and GWLF).

4. Reference watershed approach using SWAT and GWLF with three different reference watersheds to investigate the sensitivity of the method to reference watershed selection.

5. Quantify the land use/watershed changes required for TMDL implementation using GWLF and SWAT.
