In Österreich erwartet man einen Ernteausfall wie in den Dürrejahren 2017/2018. Die Folgen der Klimaerhitzung werden immer sichtbarer. Das Trügerische sind die vermeintlichen "Pausen" dazwischen.
Hydrology Paper of the Day @sub-heterogenty.bsky.social on how hydrological processes are represented in current models of karst groundwater systems: transport processes and scales of dispersion; fluid mechanics; diffusion and dispersion; chemistry and tracers; equations; and future research.

📢We are organising an #EGU26 session dedicated to groundwater-dependent ecosystems! 🌱 📅 Abstract deadline: 15 January 🔗 Session: shorturl.at/FtcXO Please share with colleagues working at the interface of groundwater, ecology, biodiversity, and/or conservation across local to global scales!
Two exciting PhD positions available in a common project between my group @tudresden.bsky.social and @lytarasova.bsky.social group @ufz.de
Larisa Tarasova@lytarasova.bsky.social · 12mo agoWe are looking for 2 PhDs in our @dfg.de #HydroSIGNs project with @sub-heterogenty.bsky.social to study resilience of hydrological systems to #global change. Interested in merging large-sample analysis and field work to study these beautiful springs and the streams they feed? Apply via links below ⬇️
It was 'student night' at IAH NSW in Sydney ( and online everywhere). Thanks to Akhi Kumar, Danyang Sun, Nane Weber and Yaggesh Sharma for presenting their groundwater research. I might have photobombed the official photo!
Great new @tudresden.bsky.social and @ufz.de collaboration with @lytarasova.bsky.social about to start soon!
Larisa Tarasova@lytarasova.bsky.social · last yr.Happy to share that our project #HydroSIGNS with @sub-heterogenty.bsky.social is funded by the @dfg.de🤩 if you are interested in resilience of #hydrological systems to #global change, #isotopes, #karst springs and some exciting #field work, stay tuned➡️we will be offering 2 PhDs to start early 2026!

Before anyone says anything about whether there were flood warnings in Texas, read this. www.forbes.com/sites/marsha...
Catastrophic Flooding In Texas - Were There Warnings?
Deadly flooding in the flash flood alley of Texas is raising questions about warnings. Here's a preliminary (but not conslusive) analysis.

Thank you #EGU25! With our last presentation, the Groundwater Management group says goodbye. See you next year again 😊
Hydrology Paper of the Day @margaretzimmer.bsky.social on how subsurface geology influences discharge and transport processes in two headwater catchments of the Diablo Range, California affected by wildfire: sedimentary and mélange lithologies, and understanding spatiotemporal DOC export.
Margaret Zimmer@margaretzimmer.bsky.social · 2y agoLatest paper out of the WS hydrology lab! Here we show spatial variability in lithology is important for streamflow behavior and carbon export, but geogenic solute export behavior is similar. agupubs.onlinelibrary.wiley.com/doi/full/10....
