Summary: Much of the world relies on groundwater as a water resource, yet it is hard to know when and where rainfall actually replenishes our groundwater aquifers. Caves that are situated above the groundwater table are unique observatories of water transiting from the land surface to the aquifer. This session will show how networks of loggers deployed in Australian caves (and mines and tunnels) have helped understand when, where and how much rainfall is needed to replenish the groundwater.
