The International Commission on Groundwater is going to submit a few problems via the LinkedIn forum. A few of us at Water Underground are going to put our thinking caps on and submit a problem or two. If you would like to be part of the discussion very early in 2018, get in touch with Tom Gleeson.
I am a hydrogeologist at University of Victoria, Canada who is interested in groundwater sustainability, mega-scale groundwater systems, groundwater recharge and discharge and fluid flow around geologic structures. My goal is fundamental and applied research and teaching to enable sustainable groundwater use.
