GGP Seminar: Todd Halihan - "Electrical Hydrogeology: A Picture is Worth 1000 Wells

Date and time: 12:15 PM - 1:30 PM, February 21, 2018

Description: GGP Seminar by Dr. Todd Halihan, "Electrical Hydrogeology: A Picture is Worth 1000 Wells"


Mankind uses economics, politics and basic instincts to make decisions about water. However, the data on the hydrologic cycle suggests we are developing water incorrectly for two basic reasons. The first is our instincts are built upon water that is visible, so we ignore evapotranspiration which causes salinization, reduced water availability, and increased infrastructure costs. The second is our development of water preceded satellite data and computing power. This resulted in ignoring complicated groundwater systems that need to be defined on the meter scale and adopting simple concepts like dams and center pivot irrigation that do not require significant data management. A framework to improve our water resources will be presented as well as some case studies on how these problems present themselves.
