Tyler Mahoney

Asst Professor

Dr. Mahoney's expertise lies in monitoring and modeling of hydrologic processes and water quality at the watershed scale. As a graduate student, Dr. Mahoney focused on simulating active pathways of sediment transport and investigating sources of sediment within stream networks. Upon graduating from the University of Kentucky, Dr. Mahoney completed a post-doc at the US Environmental Protection Agency in the Office of Research and Development under the ORISE program. While at the EPA, Dr. Mahoney focused on creating process-based hydrologic models to investigate the spatiotemporal variation in streamflow expansion and contraction in headwater stream networks. Dr. Mahoney's work at the EPA will help inform policy makers of the behavior of non-perennial streams in the Appalachian region of the United States. 

Dr. Mahoney's lab in the W.S. Speed building will focus on discerning the source, fate, and transport of sediment in watersheds nearby Louisville, and modeling sediment transport and streamflow permanence.
