Andrew Reeve is a hydrogeologist and faculty member at the University of Maine. His current research activities include studying peatland hydrology with a focus on the role of hydrology in carbon-dynamics in peatlands, assessing groundwater interaction with surface water systems, and exploring the hydrogeologic use of bore-hole geophysics. In all these activities, Reeve uses computer modeling and other computational tools to integrate and interpret field data.

Reeve’s SSI project (Safeguarding a Vulnerable Watershed) involves developing a computer model that integrates river discharge with lake level fluctuation, with a focus on the Sebago Lake Watershed in southern Maine. The Sebago team is creating an interactive virtual watershed that will allow users to simulate how changing weather patterns, human changes to the landscape, and other management practices influence flow to and water level in Sebago Lake. This computer model, delivered to users through the internet, will serve as an educational and outreach tool.
