Please, help us spread the word about Catchment Hydrology TC Student Competition!

AGU Catchment Hydrology Technical Committee@agucatchhydro.bsky.social · 2mo ago

🌍 The #AGU Catchment Hydrology TC Student Competition is now open! Open to undergrads, grad students & postdocs! 🎓 Share a seminal paper from the hydrology literature published before the year 2000. Submit your <100-word entry here: 📌 padlet.com/agucatchment... #HydrologyCommunity #EarlyCareer

We are seeking a highly motivated PhD student to join a newly funded project on “Coupling in situ high-frequency soil moisture data and remote sensing products to bridge spatio-temporal gaps explaining forest health, evapotranspiration, and water availability dynamics across forest biomes”.

Fully Funded PhD Position in Forest Ecohydrology and Machine Learning

We are seeking a highly motivated PhD student to join a newly funded project on "Coupling in situ high-frequency soil moisture data and remote sensing products to bridge spatio-temporal gaps explaining forest health, evapotranspiration, and water availability dynamics across forest biomes". The student will join Dr. Matthias Sprenger’s Watershed Hydrology Lab and work closely with Dr. Katie Martin (Watershed Ecology Lab) and Dr. Mirela Tulbure (Geospatial Analysis for Environmental Change Lab). The successful candidate will enroll in the graduate program at the Department of Forestry and Environmental Resources at North Carolina State University. This project advances the fields of forest ecohydrology by bridging the gap between in-situ observations and global satellite data using machine learning approaches. 
Required qualifications: M.Sc. with a strong academic background in Critical Zone or environmental science, hydrology, forestry, natural resources, soil science, or similar. Proficiency in one programming language (python or R). Evidence of self-motivation, independence, and interest in research. Strong written and oral communication skills.
Desired qualification: Experience with scientific writing, knowledge of statistical analysis and machine learning models, GIS skills.
Benefits: Tuition and student health insurance, $30,000 annual stipend.
Desired start date: July 2026
Interested students should fill in this form by May 25 and may wish to email Dr. Matthias Sprenger (mspreng@ncsu.edu) if there are any questions.

Hydrology Paper of the Day @gescilam.bsky.social and colleagues on communication in an age of water scarcity: issues and challenges identified in conjunction with the scientific community at EGU24; data from interviews and surveys; and the need for trust, appropriate audiences, equity, and clarity

Happy to contribute to this community paper on science communication in hydrology within the IAHS HELPING decade. We propose the FUSS framework: messages should be Few, Unambiguous, Short, and Structured. Link to paper: www.tandfonline.com/doi/full/10.... #WaterScience #ScienceCommunication

I was interviewed at AGU25 and asked what I liked most about being part of the #AGU. Without hesitation, I replied: the feeling of belonging. This year, I was deeply honored to receive the Horton Research Grant. A recognition I share with an inspiring group of scientists whose work I greatly admire.

I am honored to have received first place in the Young Researcher Award, in the PhD category, from the Brazilian Association of Water Resources (ABRHidro) at the XXVI Brazilian Symposium on Water Resources. For those who would like to explore the study in detail, here is the link: rdcu.be/eSBJl

HUGE HYPE for our #CatchmentCup2025 WINNER by overwhelming majority: the ONÇA Catchment in Brazil!!! Thank you to everyone who voted for their favorite catchments throughout the past month to make this all possible. Happy last day of Catchment Cup and Happy Halloween 🎃 from AGU H3S! 🎉🎉🎉

Keep those votes rolling in for #CatchmentCup2025! The first catchment in our championship round is the Onca Catchment located in Brazil! The Onca Catchment is the longest continuous monitoring of an outcrop area of ​​the Guarani Aquifer System from 2000 to the present day... (1/2)

Hydrology Paper of the Day @gescilam.bsky.social on quality control, validation and standardization of groundwater data for Brazil: removing duplicate data with uncertain provenance; matching the purpose of groundwater wells with water sector use; and mapping well density and water levels.

Gescilam Uchôa@gescilam.bsky.social · 10mo ago

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
