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 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), the National Oceanic and Atmospheric Administration’s sponsored Mississippi-Alabama Sea Grant Consortium and the Environmental Protection Agency’s Gulf of Mexico Program.

He regularly publishes articles pertaining to his research and has chaired five doctorate and over 20 master’s students. He served as an associate editor for the ASCE Journal of Hydrologic Engineering from 2008-2014 and consulted as a registered professional engineer in Florida and Nevada in the 1990s. He teaches courses in water resources, including an abroad course primarily based in Innsbruck, Austria, and courses in the UA Honors College.

In 2020-2021, he received a Fulbright Research and Teaching Scholar award to the University of Trento (Italy). He will teach a course in Paleohydrology while conducting research in climate and water.

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.
