@hydrochrista.bsky.social @domciruzzi.bsky.social, and I asked hydrologists across the country for their syllabi so we could investigate how instructors were teaching hydrology courses and think about the future... Here’s what we found + suggestions agupubs.onlinelibrary.wiley.com/doi/10.1029/...
The Current State of Undergraduate Hydrology Courses in North America: A Path Forward
Examined syllabi for introductory courses in hydrology The titles, topics, and approaches to assessment varied widely across courses Found limited consensus in how hydrology courses are taught a...

Wrapping up your PhD? I’m planning to hire a postdoc in the next few months (start date flexible). Will start formally advertising soon, but you heard it here first!! Possible research topics include - critical zone hydrology, agricultural water quality, SW-GW interactions. Reach out if interested!
Recently, all the AAAS Science & Tech Policy Fellows at EPA were terminated from our positions with little notice and for no clear reason. This effectively ended a partnership that had been going since 1980 and which had brought hundreds of scientists to the EPA as fellows, many of whom stayed. 1/7
Coastal Massachusetts in August? Sure! Apply to attend our CUAHSI-sponsored workshop on stakeholder-informed spatial modeling for hydrologic sciences. Let me know if you have any questions! www.cuahsi.org/workshops/st...

Hydrology Paper of the Day @margaretzimmer.bsky.social on how subsurface geology influences discharge and transport processes in two headwater catchments of the Diablo Range, California affected by wildfire: sedimentary and mélange lithologies, and understanding spatiotemporal DOC export.
Margaret Zimmer@margaretzimmer.bsky.social · last yr.Latest paper out of the WS hydrology lab! Here we show spatial variability in lithology is important for streamflow behavior and carbon export, but geogenic solute export behavior is similar. agupubs.onlinelibrary.wiley.com/doi/full/10....
Pleased to announce my lab will soon be hiring a postdoc! Join an interdisciplinary group working on ecosystem change following the last glacial maximum in southeast Alaska. Substantial modeling skills are a big plus! Applications due April 20th. coreykrabbenhoft.com/join-us-2/

Oh I absolutely can’t wait to read this new paper! The “little bit of everything” in this paper is everything I love!
Nate Jones@floodhydrology.bsky.social · last yr.Big CONGRATS to @kacizarek.bsky.social!!! Her new paper is out in @agu.org's JGR-B! The paper has a little bit of everything -- N biogeochemistry, intermittent stream hydrology, concentration-connectivity relationships! Check it out here: agupubs.onlinelibrary.wiley.com/doi/full/10....

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...
National Science Foundation fires roughly 10% of its workforce
NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.

Check out this thread with Fact Sheets and interactive tools to learn about NSF’s impact across the US, in your state, and at universities in your community!
Dr. Jennifer Wade@volcanojw.bsky.social · last yr.Some folks have asked, given recent news, “how do I show my friends/family the impact of NSF?” We have some easy Fact Sheets for you! Here’s a brief thread about this website: new.nsf.gov/about/fact-s... which hosts a ton of useful one-pagers.
A little bit delayed, but I hear it's picking up over here so sending this out into the world: our Lafayette team including Rachel Hurley (now grad student at WPI), Dave Brandes, and me put out this piece on flashiness across the Mid-Atlantic: onlinelibrary.wiley.com/doi/abs/10.1...
Drivers and Buffers of Stream Flashiness in the Mid‐Atlantic United States
In this study, we investigated flashiness across 195 Mid-Atlantic sites, each within one of seven different physiographic regions. Our findings identified several drivers and buffers of flashiness, e...
