  • M.S., Civil Engineering, University of Florida, 1987
  • B.S., Civil Engineering, University of Florida, 1985

Dr. Glenn Tootle’s research efforts focus on climate and climate change impacts on water resources, including paleo (using tree rings) reconstructions of hydrologic variables, long lead-time forecasting of streamflow, drought frequency, weather modification impacts on streamflow, and alpine glacier impacts on streamflow.

As both lead and co-principal investigator, he has multiple awards from the National Science Foundation’s Paleo Perspectives for Climate Change program (NSF P2C2), the National Science Foundation’s Innovations at the Nexus of Food, Energy and Water Systems (NSF INFEWS) program, the National Science Foundation’s Research Traineeship Program (NRT), the National Oceanic and Atmospheric Administration’s sponsored Mississippi-Alabama Sea Grant Consortium, the Environmental Protection Agency’s Gulf of Mexico Program, and CIROH (USGS).

He regularly publishes articles pertaining to his research and has chaired both doctorate and master’s students while actively engaging undergraduate students in research. He served as an associate editor for the ASCE Journal of Hydrologic Engineering and consulted as a registered professional engineer in Florida and Nevada in the 1990s. He teaches courses in water resources and has led an abroad program (UA in Europe: Climate & Water) since 2012. In 2021, he was selected a Fulbright Research and Teaching Scholar to the Università di Trento (Italy).

He retired as a Captain from the U.S. Navy Civil Engineer Corps (Navy Seabees) after ~25 years, which included two post 9/11 mobilizations and service as commanding officer for Naval Mobile Construction Battalion TWO-FIVE.

Awards and Honors

In 2021, he served as a Fulbright Research and Teaching Scholar to the University of Trento (Italy). While in Trento, he developed two new UA courses (CE 270: Field Studies in Water and Climate and CE 574: Paleohydrology) which will be offered during the UA Faculty Led abroad program he leads each summer to Italy.
