Hydrology Paper of the Day @jpgannon.bsky.social @hydrochrista.bsky.social @domciruzzi.bsky.social on understanding the teaching of hydrology at the undergraduate level: course titles, assessments, and objectives; textbooks and grading; and the need for shared educational resources and objectives.

Snow drought continues across much of the western U.S. For much of the region, below normal precipitation is partly to blame (OR, CO, UT, NM), while above normal temperatures have occurred across nearly the entire region.

New preprint led by Aaron Heldmyer and Roy Sando: Random forest + donor gages to predict daily streamflow drought across CONUS. Regional drivers differ—soil moisture, precip, SWE matter most. doi.org/10.5194/egus...

🔥💧 New paper out in Environmental Research: Water led by Brian Ebel! Synthesis shows how wildfires fundamentally shift hydrologic processes and streamflow generation—from infiltration and runoff to baseflow and flood response — post wildfire. iopscience.iop.org/article/10.1...

I wrote a commentary discussing Daniele's huge new global synthesis of controls on hydrological processes in forested catchments: read it here: rdcu.be/eXTrq . Some surprising findings on the importance of overland flow, soils and antecedent conditions.

New paper! Real-time flood inundation mapping (FIM) services are an incredibly valuable tool for emergency management and affected communities. But do their visualizations help users quickly and accurately interpret information to make decisions? onlinelibrary.wiley.com/doi/10.1002/...

I’ve always been more of a photographer than anything else when it comes to art. Still trying sketching sometimes, but also enjoying creating vector art versions of my #riversfromabove photos, and some other travel photos. I feel like style is “you love/hate it” without much in the middle. Thoughts?

A piece that felt particularly relevant to write

Hydrology Paper of the Day @andy-baker.bsky.social on quantifying the drip of water underground as part of rainfall recharge: groundwater monitoring near the water table in Australia; why mines, tunnels and caves are essential monitoring locations; and relating rock aquifer response to rainfall.

Working with large-sample hydrology datasets and curious about how maps with varying levels of detail influence the identification of geology–streamflow relationships? Check out our latest preprint at HESS! #Hydrology #CatchmentHydrology #LargeSampleHydrology #Eawag #hightlightpaper #HESS

@rarakihydro.bsky.social leads an exiting new preprint that maps dominant hydrologic processes across >14k US watersheds using streamflow signatures + ML. It’s been such fun following Ryoko and Hilary’s leadership alongside Admin, Anne and Gemma. egusphere.copernicus.org/preprints/20...

Happening this morning! Run don’t walk to room 228-230 to hear @zhaozhechen.bsky.social talk hydroclimate-ET synchrony!! @agu.org

In case you missed it live, a full recording of my rapid-response livestream regarding news surrounding the proposed imminent and sudden dismantling of the National Center for Atmospheric Research (NCAR) is now available.

Another example - from just today - of excellent and essential climate and weather research from @ncar-ucar.bsky.social with clear impacts on flood-prone communities doi.org/10.1038/s432... #NCAR

I 'll have a special rapid-response livestream for 8:30am PT today to discuss dire implications of this proposal to dismantle NCAR. Due to extreme fire weather in Boulder today (and associated pre-emptive power outages/NCAR closure), I am going live ASAP. www.youtube.com/live/FTKW68R...

The latest UK Hydrological Summary has been published 🌧️ November was UK's wettest month so far in 2025 & many areas have shifted from drought concerns to flood risk. Groundwater levels notably low and reservoir levels still below average in parts. Winter rainfall amount will be crucial. 🧪 1/

Photos from the Patapsco River in Maryland yesterday. Lucky to have the snow stick to the trees despite the high winds! #riversfromabove

The fact that parts of Washington are seeing record-breaking flooding this week is not surprising given that 1) many locations saw record 24hr precipitation (well above 100yr ARI) & 2) near-record temperatures *simultaneously* (no snow in mtns, so all precip became runoff). #WAwx

A powerful atmospheric river has drenched Washington state with nearly 5 trillion gallons of rain over the past week. The deluge is linked to warm water and air, along with unusual weather conditions tracing back to tropical cyclone flooding in Indonesia.

Officials warned of “locally catastrophic” river flooding in Washington state Wednesday amid a major atmospheric river storm that was poised to drop 20 inches of rain in the Cascade Range. Two rivers north of Seattle, the Snohomish and Skagit rivers, were predicted to crest at record levels.

Washington Gov. Bob Ferguson declares a statewide emergency in response to flooding occurring throughout the Pacific Northwest. www.king5.com/article/weather...

Bettina Schaefli and I warmly invite you to submit abstracts to a new EGU session HS2.2.5 New Developments in Hydrological Synthesis Abstract submission: www.egu26.eu/session/55911 1/6

On Wednesday, widespread heavy rain & very high snow levels (7,000-9,000 feet) will cause enormous runoff into already swollen rivers. Widespread moderate to major flood is likely, with some rivers expected to experience *record* flooding (esp. Skagit & Snohomish). #WAwx [2/3]

Been focused on photos of rivers from above for a few years, but starting to try my hand at rivers from below. Wish I could be snorkeling every day! sites.google.com/view/riversf...

New paper alert: "Diverging Impacts of Snow Fraction and Soil Drainage on Seasonal and Annual Water Balances Across Snow-Influenced Catchments" Led by Zeqiang Wang. A synthesis of some controls on spatial variations in snow-influenced hydrology across the USA. doi.org/10.1029/2025...

Born out of our WaterSciCon sessions and workshop in 2024 (thanks @cuahsi.bsky.social and @agu.org!) this was a really fun one to write! We hope it spurs thoughts and new collaborations.

Just now getting around to posting about this. Nice to be part of this study with Quan Zhang and a host of others! We find that the water use efficiency from increased CO2 does not lead to higher tree growth. You can find the study here: www.nature.com/articles/s41...

Hydrology Paper of the Day @felipesaa.bsky.social @lytarasova.bsky.social on accurate modelling of nitrate concentration: capturing soil moisture patterns and hydrological connectivity during wet and dry conditions; pattern identification with explainable AI; and catchments in the Midwestern US.

Ever wonder how streams and rivers differ in naming across the country and what the most common names are? Here are the most common names of stream/river segments by HUC2 region across the U.S.

Hydrological extreme impact on aquatic species in the news: phys.org/news/2025-10...

Expected impacts from this weekend's major SoCal storm--which now appears likely to feature widespread flood risk and also a few severe thunderstorms--continue to increase. I will have a blog post and YouTube livestream at a TBD time later today to discuss. #CAwx

“On the Structure of Temporal Variability of Streamflow Responses and the Role of Timescale Interactions — A Synthesis” A nice synthesis showing how streamflow variability emerges from interacting timescales — fast events like storms intertwined with slower processes like soil moisture and memory.
