More than 30 years of InSAR data, historical archaeological data, groundwater level data, and ground fissure data are available on the new Arizona subsidence web app #groundwater

Low Snow Reserves – again.
Switzerland heads into spring with 30–60 % of normal snowpack. Less melt = less groundwater recharge. Rain gauges won't show you what's underground. Direct measurement will.

Over on LinkedIn, my colleague Prof. Wendy Timms has a nice video of her on groundwater recharge fieldwork in the lava caves at Byaduk. Check it out!
Come underground in this rough cut quick video from the past few days (and earlier)! We are exploring the relationship between each rainfall event and water underground - led by Prof Andy Baker FRSN FAGU with a wide research team. The Australian Research Council funded setup of this National Observatory*. Shout out to local helpers including catchment managers, geotech engineers and gold geologists, my family, and students and uni staff who have ventured into our underground spaces in mines, tunnels and caves for this valuable data (2022-to date). It's a followup to an IAH2025 presentation* on implications of record low soil moisture deficits across parts of Australia for water availability in catchments and basaltic aquifers and associated reports on drip seepage in local mines. Now back to the computer and catching up on desk work.... *The IAH presentation is here with links to download several journal papers and articles: https://lnkd.in/geCsZSji

It's possible to turn around a groundwater crisis
A look at cases where groundwater depletion has rebounded and how: reduced water use, deliberate recharge, switching to alternate supplies. In a few cases ground subsidence has rebounded slightly.
