Monitoring from the air. Photo: Aalborg University Drone Research Lab GRUNDFOS FOUNDATION RESEARCH The SuperTEM project will further develop the TEM method by creating two systems: the first to monitor dynamic groundwater processes and the second to characterize 3D geology in hard-to-access terrain. The monitoring system will be installed semi-permanently at key locations to provide images of the subsurface at daily intervals. The variations observed in these time-lapse images of the subsurface allows one to follow for in- stance changes in groundwater levels as a response to water extraction at a well. These images allow us to track dynamic groundwater processes key to understanding the state of aquifer systems and to ensure sustainable management practices. Everything without drilling. The second system will be used for high-resolution 3D characterization of the subsurface (photo). The receive components of the TEM system will be miniaturized such that it can be flown using a commercial drone. Such an ap- proach will permit characterization in rugged terrain (e.g., shrubs or unstable ground) or environmentally sensitive areas where highly detailed images are needed. HGG is working directly with the Drone Research Lab of Aalborg University to achieve these goals.
