MODELING TEMPERATURE AND DISSOLVED OXYGEN IN THE CHEATHAM RESERVOIR WITH CE-QUAL-W2 By Brett M. Batick Thesis Submitted to the Faculty of the Graduate School of Vanderbilt University In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE In Environmental Engineering August 2011 Nashville, Tennessee Approved: Professor Eugene J. LeBoeuf Professor Alan R. Bowers 1 ACKNOWLEDGEMENTS This project would not have been possible without the support of the United States Army Corps of Engineers (USACE), Nashville District Water Management Team. Specifically, I would like to acknowledge the support of Robert B. Sneed and Jeffrey S. Gregory of USACE. Without their support this project would not have happened. I would also like to thank my advisor Eugene J. LeBoeuf. His wisdom and guidance was immeasurable. Without his support, this thesis, and my transition marked by this thesis, would have been impossible. Thanks also to my family. Lana, Ethan, and Emily never lost sight of the goal. They were greatly supportive of my efforts and very understanding of the time requirements of this project. ii Table of Contents ACKNOWLEDGEMENTS ............................................................................................................... ii LIST OF TABLES ............................................................................................................................ v LIST OF FIGURES ......................................................................................................................... vi I.
