📢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

Six people standing in a room, Sydney cityscape behind them

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!

Last chance to submit your abstract to the classical Runoff generation session!

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.

Before anyone says anything about whether there were flood warnings in Texas, read this.

261 days under review after 1st submission. This is exactly 40 days beyond your average time for acceptance after (!) re-submission. @natgeosci.nature.com please help!

Die @dfg.de bewilligte heute zwei neue Sonderforschungsbereiche/Transregios mit Beteiligung der #TUDresden zu den Themen Agile Mobilität und nichtalkoholi­sche Fettleberer­krankung. 🔬

A study in Communications Earth & Environment finds that snowmelt runoff in the western US is composed primarily of older groundwater, dating back 5.7 years on average. go.nature.com/4iXF5ZX ⚒️ 🧪

Thank you #EGU25! With our last presentation, the Groundwater Management group says goodbye. See you next year again 😊

Count on me to come around and ask stupid questions 😁

First prevention of our group at #EGU25 Go Tanía! 😊

Headwaters and Wildfire in California Wildfire is a fact of life in California, but good land management can reduce its severity—and harm to people and property. Learn more in our new fact sheet.

@ppicnotes.bsky.social has a new fact sheet regarding wildfires in California's headwater out today. Worth a read. 1/3

Thanks so much for taking care of it!

Dear @naturegeosci.bsky.social 160 days in review. Is that normal? I'm used to get notice much quicker from other Nature group journals...

Thank you @kinarnicholas.bsky.social that's a big honor for us 😊

This comes a bit more than 10 years after “Karst water resources in a changing world: Review of hydrological modeling approaches” in the same journal (doi.org/10.1029/2023...) with young me as first author. So proud of Kubra getting this out now :)

Our new review led by my PhD student K. Özdemir Çallı in Reviews of Geophysics explores solute transport modeling in karst systems—key for predicting & managing water quality in a changing world. 🌍🔬 🔗 doi.org/10.1029/2023...

Proud to be part of this team!

@matthiasforkel.bsky.social you are mentioned, too 😊

Learning about the use of social media in science at our faculty'sPhD event @tudresden.bsky.social by Benjamin Griebe. @bsky.app seems to be the preferred choice amongst scientists 😊

New EU funded project CRossWATER at the Institute of Groundwater Management at @tudresden.bsky.social to ensure water security in the European City of Görlitz-Zgorzelec. Read more at www.linkedin.com/pulse/new-eu... #Groundwater #Hydrology #ClimateAdaptation #WaterSecurity

**Paper alert!** Tamara Leins & Mirjam Scheller lead a new karst study at @tudresden.bsky.social on karst aquifer vulnerability to contamination under climate & land-use changes. 🌍💧

Amazing! Thank you Luka!

Welcome to my Blue account! This will replace my Twitter account @sub_heterogenty for well known reasons. Looking foward to scientifc exchange rather than hatred and spam 😁
