Our team has been developing a novel teaching and research field site for fractured rock hydrogeology. Dozens of wells and multiple consulting reports with extensive hydrogeologic information are available at the site, which is only 15-minute walk away from our office. Fractured outcrops are not only accessible from a nearby river bluff but also from an underground cavern where an exposed ceiling shows vertical fractures. The team conducts extensive fieldwork every summer, including dye tracing and hydraulic testing using a multi-packer system. We are developing a 3D numerical groundwater model based on multiscale characterization of the fractured aquifer. Peter and his colleagues have also incorporated field activities at the site into several courses at UMN.
