Abstract: Earth imaging data – acquired using satellite, airborne, and ground-based geophysical methods - can be used to provide information about the properties and processes in groundwater systems. Over the past ten years in California, the combination of extensive periods of drought and the introduction of groundwater legislation has raised the awareness of 1) how little we know about the functioning of groundwater systems and 2) how difficult it is to get the data we need to study and manage these systems. Significant improvements in geophysical technology and in the spatial/temporal coverage with satellite data have allowed us to develop new ways to integrate various forms of data to image the groundwater systems of California. We are now using data from satellites (primarily InSAR) and from airborne and ground-based EM systems to map and monitor saltwater intrusion in coastal aquifers; develop groundwater models; and search for and assess potential sites for recharge. With recent financial commitments from the state, Earth imaging technologies will play a critical role in supporting the sustainable management of California’s freshwater resources.
