The 3rd annual hydrogeophysics field camp, offered by Dr. Kamini Singha, has come to completion. Nine undergraduate participants, from rising sophomores to rising seniors, spent three weeks collecting a wide range of data from the CZO and nearby Lake Perez. New data included images from the optical televiewer and gamma logs, GPR, pumping/slug tests and electrical resistivity measurements. Using COMSOL, a multiphysics software designed for analysis and visualization, the students built numerical models and learned the intricacies of field data interpretation.
