Hi everyone! Excited to share our new paper: “A groundwater well database for Brazil (GWDBrazil)” published in Scientific Data: www.nature.com/articles/s41... In partnership with Geological Survey of Brazil

🌍 New blog post! I present the study ‘Severe droughts reduce river navigability and isolate communities in the Brazilian Amazon’, which examines how #drought impacts community isolation in the #Amazon River basin. Read more on the AGU Water & Society TC blog👉 linkedin.com/feed/update/...

🌊 This week in our #AGU25 #CatchmentHydrology Early Career series, we highlight: “Deciphering surface water–groundwater connectivity using chemical and stable isotope tracers (H and O) in the headwaters of São Francisco River, Brazil” by Marcela Aragão et al. (2025).

🌡️ This week I highlight human-perceived heatwaves in Brazil 🇧🇷. A study by Ballarin et al. (2025) projects major increases in exposure, especially in São Paulo & Minas Gerais—both nearly quadrupling. Read more on the AGU Water & Society TC blog 👉 www.linkedin.com/feed/update/...

Hydrology Paper of the Day @gescilam.bsky.social on groundwater levels in Brazil and how streams are losing water: a geography of river classifications; agricultural use and arid conditions; climatic drivers and river connectivity determined by remote sensing; and a novel Effective Catchment Index.

🌊 This week we highlight the paper: “Widespread Potential for Streamflow Leakage Across Brazil” by @gescilam.bsky.social et al. (2024). ✨ Every two weeks until #AGU25, we’ll feature a publication in #CatchmentHydrology from an early career scientist who shared their work with us.

Earlier this year, we invited undergrads, grad students & postdocs with recent publications in #catchmenthydrology to share their work with us📄 Starting now, we’ll highlight one of these papers every two weeks until #AGU25 — helping #earlycareer scientists spread their research!🚀

🚨 The #AGU Catchment Hydrology TC Student Competition closes August 31! Please help us spread the word to undergrads, grad students, and postdocs working in #catchment #hydrology. 🌊 📌 Full details in our last post and on the TC website. #EarlyCareerScientists #StudentOpportunity

Thank you @kinarnicholas.bsky.social for sharing our article on @eos.org! Always a pleasure to follow your Hydrology Paper of the Day series—such a great way to stay connected with the latest in hydrology. 🌊📚

Grateful for the opportunity to share our findings in @eos.org on river–aquifer interactions in Brazil 🌊💧 (rdcu.be/egq5l). We highlight the widespread prevalence of potentially losing streams — hoping to support more integrated groundwater – surface water management in the country.

Water pumping can make rivers leak underground. It’s happening all over Brazil. eos.org/articles/bra...

The #AGU Catchment Hydrology TC wants to highlight your recent work! If you’re an undergrad, grad student, or postdoc with a recent publication from the last 6 months, we’d love to feature it on our social media. Submit your paper here 👉 forms.gle/7zHyarnmYZxX...

Thanks, @agucatchhydro.bsky.social, it was fun to participate in the #AGU Catchment Hydrology TC #EarlyCareer Competition last year. I hope to participate again this year.

Hydrology Paper of the Day @agucatchhydro.bsky.social on human-observable indicators of soil wetness: qualitative observation classes related to quantitative datasets; field testing conducted in the Alpthal valley of Switzerland; three test datasets; and statistical method validation.

AGU urges the Trump administration to immediately renew U.S. federal commitment to climate science. The U.S. must restore critical climate science leadership for a secure, prosperous future for the country and the world. Read AGU’s statement here: news.agu.org/press-releas...

AGU is committed to supporting our members through challenges affecting the scientific community. Whether you need career resources, mentorship, policy advocacy tools, or publishing support, we’re here to help.

Amongst all of this, our students are still publishing excellent papers. My recent Masters student Annie Holt, now at NWS, shows how geologic age and (region-dependent) wetland fraction metrics can be used to improve our predictions of baseflow in watersheds across the U.S.: doi.org/10.1002/hyp....

1/4 Yesterday was an extraordinary day in my #earlycareer as a researcher in Brazil. My master's/doctoral research (nature.com/articles/s41...) was featured on two of the largest open TV channels in #Brazil.

1/2 I attended my first #AGU Annual Meeting this year and was truly honored to receive the David S. Miller Young Scientist Scholarship, the #Ecohydrology TC Tiny Grant, and the #WaterQuality TC Tiny Grant! #Groundwater #Hydrology #EarlyCareer #ScienceCommunity

Excited to share that I’m one of the winners of the AGU Water Quality TC Haiku Your Research contest for #AGU24! The core message of both my work and haiku: we must manage surface and groundwater together. Big thanks to the AGU Water Quality TC for this opportunity! #AGU24 #ScienceCommunication

Excited to share that @pesquisafapesp.bsky.social Magazine published an article (in Portuguese) about our recent paper in Nat. Commun. Grateful for the opportunity to discuss our findings and share their importance with the general public. Check it out: revistapesquisa.fapesp.br/esgotamento-...

Research finds 55% of Brazilian streams seep into aquifers, revealing widespread water loss that could reshape water use strategies and impact river-reliant ecosystems. #Bluesci www.nature.com/articles/s41...

Big data in #Brazil suggests widespread potential for #river water loss to #aquifers particularly where there's extensive #groundwater pumping. Highlights need for conjunctive groundwater & surface #water management to balance water use & ecosystem needs www.nature.com/articles/s41...
