See how rivers evolve over time! This hybrid model maps surface water 500x faster than traditional models with 97.6% accuracy, helping us predict future water availability and flood risk. Read more: doi.org/10.1016/j.jh... @reedh2o.bsky.social #Hydrology

Groundwater feeds 90% of Brazil's rivers and supplies water to over half its cities, but data is scarce. These researchers made the 1st nationwide water table depth map to help close the gap. See how: doi.org/10.1088/1748... @ioppublishing.bsky.social @reedh2o.bsky.social #Hydrology

Four-panel figure. Panels a and b show maps of Brazil at high resolution. Panel a shows predicted depth to groundwater across the country, with shallow water tables in blue and deep ones in orange, following the outlines of major hydrologic regions. Panel b shows how uncertain each prediction is, using the same map layout. Panels c and d zoom into a section of the São Francisco river basin, overlaid with the locations of irrigation systems, which are large circular farm fields that pump groundwater. Panel c shows predicted groundwater depth in this zoomed in area, revealing a clear pattern of deeper water tables clustering around the irrigated fields. Panel d shows prediction uncertainty for the same area, which increases in the deeper zones. Together, the maps show that groundwater depth varies widely across Brazil, follows river networks, and picks up on real signs of groundwater pumping for irrigation, even though pumping data was not used to build the model.

#ThrowbackThursday! As summer winds down, we're looking back at Groundwater Modeling and More 26. We kicked off our summer with a bang! This amazing conference was packed with great presentations, keynotes, networking, and so much more. 🌎💧 📸 PC: Sameer Khan, Fotobuddy @reedh2o.bsky.social

A full lecture hall of attendees listening attentively to a keynote speaker. A slide with a world map figure is displayed at the front of the room.

🌊 QUEST 26 is a wrap! A week of educators exploring hydrology beneath the surface with hydrologic cycle activities, water's connection to ecosystems & communities, and local NJ phenomena for the classroom.💧📚 @reedh2o.bsky.social @princeton.edu #Hydrology

Two educators examine a clear cup during a classroom activity. One holds the empty cup near eye level while the other begins pouring blue water into it. Other educators talk in the background.

A group of educators smile with arms outstretched during an activity, while one crouches to move around the group.

Three educators examine rocks together. One points at a specific rock, one looks closer with a magnifying glass, and the third observes.
