In the preprint, led by Stacey Priestley (CSIRO), we discuss the first results from Australia’s NGROS network. This network uses loggers in underground spaces such as caves, tunnels and mines, to observe potential recharge events. We then relate them to specific rain events, to work out how frequently groundwater recharge might occur and how much rainfall is needed. TL;DR – groundwater recharge at our sites in southern and eastern Australia is only likely to occur a few times a year when rainfall is very high to extreme.

Like most preprints, this manuscript is currently in the review process for publication. We’d value any comments and feedback.
