We were also present with two posters.

Prof. Thorsten Wagener introduced the Potsdam WaterHub during his keynote at the Geo.X Annual Meeting 2025. The theme of this year's Geo.X meeting was "Water in Motion".

This work eventually got some media coverage.

😱 Every second person dies from unnecessary risk-taking behavior during #disasters. We need to educate the public to reduce #disaster mortality further.
👉 #ClimateChange is kicking in; we are facing more and more socio-natural #hazards without prior experience.

A new study in NHESS investigates the decreasing groundwater recharge rates in Brandenburg.

A few years ago, we visited the soil-survey archives of a region in Brazil. We digitised the data and began developing a framework for developing soil maps that accurately (pedologically) represent soil profiles in the tropics. The result is here: www.sciencedirect.com/science/arti...

Submarine canyons preferentially form where the seafloor is steepest—not where rivers bring much sediment. Our global study reveals what controls canyon distribution and the world’s oceans.

Für ihre herausragenden Beiträge zum Verständnis und zur Minderung von Hochwasserrisiken sowie zur Entwicklung von kommunalen Anpassungsstrategien wurde Prof. Dr. Annegret Thieken durch die @egu.eu die Plinius-Medaille 2025 verliehen. Mehr Infos: www.uni-potsdam.de/de/medieninf...

🏆 Celebrating outstanding science at #EGU25

🏅 Annegret Thieken – for shaping flood risk management pratices
🏅 Mariana Madruga de Brito – for her innovative use of NLP for climate impacts
🏅 Sergio M. Vicente Serrano – for advancing drought assessment tools

Really inspiring work! 🙌

Analysing 1,686 glacier lake outburst floods (GLOFs), Veh et al. (2025) found that despite growing glacier lakes from climate change, GLOFs are getting smaller. Most dangerous ice-dammed lakes are declining.

New study uses global observations and shows that large-scale #irrigation changes local #rainfall, leading to more afternoon rain events 10 to 50 km downwind of irrigated areas. This can help constrain #climate models and support #WaterManagement. @gerics.bsky.social www.nature.com/articles/s41...

Here's my first blog entry on using #TopoToolbox with #Python. See how to run Boris Gailleton's GraphFlood and display water depth along with a longitudinal river profile.

#Urbanisation has long raised #LandslideRisks. In #Medellín, we traced this link back nearly a century. #InformalSettlements face 2–3.5× more fatalities/km² than formal areas. Urban development strategies must consider #Geohazards.

Do we do research, where it matters? Globally research on floods, droughts, and landslides is so biased that 100 times more people need to be affected in low-income countries before they receive a similar research attention than high-income countries agupubs.onlinelibrary.wiley.com/doi/10.1029/...

There is no need to use full landslide polygons in hazard models! We use topology & morphology to separate source & runout areas with <20% accuracy.

#Monsoon rains are vital to feeding billions but pose great risks during extreme events, such as the 2022 #Pakistan floods. We reviewed recent research on monsoon precipitation, focusing on complex networks that may have helped predict #ExtremeRainfall.

What a giant review. Sebastian Gnann from the @uni-freiburg.de (and formerly @unipotsdamwater.bsky.social) together with numerous coauthors (including myself) review how #topography affects to global terrestrial water cycle.
