Thanks so much for entrusting me to kick off #USRSE25! What a great conference and a super engaged audience. So much fun

What’s an aquifer? It’s layers of rock or sediment that hold and move water underground —like a hidden reservoir beneath our feet. We demo this with both a physical & virtual model for outreach events. Curious? Ask us more! #Groundwater #Hydrology @reedh2o.bsky.social

💧 Water science has a language all its own. Here’s a quick look at some essential hydrology terms—perfect for students, educators, and water nerds alike. #Hydrology #WaterScience 🔁 Repost to help folks learn the lingo! @reedh2o.bsky.social

💧 #FunFactFriday 💧 Billions of people rely on groundwater every day—but most don’t even know it! 💧🌍 Do you know where your water comes from? 👇 #WaterFacts #Hydrology @reedh2o.bsky.social

Discussions are beginning around a possible MODFLOW & More Conference in 2026.💧We’d love your input as we consider options. Please take a few minutes to complete our short survey: igwmc.princeton.edu/modflow-2026... Also, check out 2024 highlights + past short course info @reedh2o.bsky.social

IGWMC led a hydrology unit for QUEST teachers last week! 💧 Participants learned how Earth’s water is distributed through the #Freshwater #Saltwater Challenge, then used #aquifer models to explore groundwater flow and aquifer types. @reedh2o.bsky.social

Students took on Water and Climate Week at @thewatershedinstitute —exploring #hydrology, #modeling, #ML, #coastalhydrology & #SciComm. The week ended with climate art inspired by places they love. @reedh2o.bsky.social

Ever wondered how hydrologists observe water movement over time? A hydrograph shows streamflow changes from rain, snowmelt, and more. We use them to study floods, seasonality, and how water moves through landscapes. #Hydrology #Groundwater #Hydrograph @reedh2o.bsky.social

As groundwater flows through layers of soil and rock, those materials help filter out impurities. 💧⏳ That’s why water from aquifers often needs less treatment than surface water. What’s a cool science fact you love? Drop it below! ⬇️ #FunFactFriday #WaterScience @reedh2o.bsky.social

We were so excited to be invited to facilitate Mole Day at Foundations Academy Charter School on June 2! Students explored water science through aquifer models, crafting water cycle bracelets, and taking the freshwater challenge.💧 #STEM #WaterEducation #MoleDay @reedh2o.bsky.social

US climate scientists need all the help they can get. Including from foul-mouthed comedians! 🤡😱😱 Watch Emmy Award-Winning David Cross team up with Prof Michael Oppenheimer in the US launch of the hit series "Climate Science Translated". #climate #arresteddevelopment #climatescience

Flashback to Water and Climate Academy week! 🌊 Students explored how water science connects to climate change—diving into hydrological topics—then shared insights through science communication. @reedh2o.bsky.social #FlashbackFriday #Hydrology #MachineLearning #SciComm #ClimateChange

Spring Into Science 2025 was a blast! 🔬💧 Students explored aquifer models, our density tank & met Jerome the Drone 🚁. Great to see young scientists dive into water sustainability! 💙 #SpringIntoScience #Hydrology #STEM @reedh2o.bsky.social

Some groundwater is under so much pressure that it flows to the surface without the need for pumping! 🌊 What’s a surprising water fact you know? Tell us below! ⬇️ #FunFactFriday #WaterCycle @reedh2o.bsky.social

The fact that my awesome group is excited to teach kids about water makes me so happy. Hope this brightens your feed. #maxwellgroupadventures

You can get my book even though it still says "pre-order"! press.princeton.edu/books/paperb... (for a 30% discount, use code P327 on the PU Press website)!

🌍💧 Happy #WorldWaterDay! Glaciers store & slowly release water, feeding rivers & groundwater. But rapid melting disrupts this balance, threatening water supplies. Protecting these icy lifelines secures our future! #GlacierPreservation #Groundwater @reedh2o.bsky.social @un-water.bsky.social

#FlashbackFriday to Spring Into Science 2024! 💧🔬 Students explored aquifer models, a density tank & met Jerome the Drone 🚁. Come see us for Spring Into Science 2025 on April 5! #STEM #Outreach @reedh2o.bsky.social Sign up: scienceoutreach.princeton.edu/events/2025/...

How do disasters shape learning?🌏 A decade after Super Typhoon Haiyan, this study analyzed 15K+ news articles, 300 papers & survivor stories to understand recovery & resilience. @reedh2o.bsky.social #DisasterRecovery #Resilience #RiskComms www.nature.com/articles/s44...

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week. "...the birthplace of weather and climate forecasting"

Jerone the Drone gives us a new view of water! 🚁💧 Its high-res images of temperature & elevation reveal patterns in soil moisture, terrain & hidden details—like dense vegetation and even wildlife! 🌍 #RemoteSensing @reedh2o.bsky.social

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...

💙 Water has our hearts this Valentine’s Day! 💧🌍 Let’s celebrate our love for hydrology and the hidden water that sustains us. #ValentinesDay #HydrologyLove #WaterScience @reedh2o.bsky.social

Flashback to QUEST 2024! 💧 This program helps K-12 educators with science & math teaching. One week, led by @reedh2o.bsky.social & the IGWMC team, explored hydrology by interfacing with real data, modeling, and using interactive tools. 📸 PC: Sameer Khan, Photobuddy #FlashbackFriday #Hydrology

💧 Hydrologic models often oversimplify water systems. This method brings in small-scale channel details to improve predictions without increased computational costs! www.frontiersin.org/journals/wat... #Hydrology #WaterModeling @reedh2o.bsky.social

🌊 How does groundwater impact coastal flooding? A Princeton Alliance for Collaborative Research and Innovation (PACRI) project between UMES and IGWMC is tackling this question in the Chesapeake Bay. Research and education driving innovation! #ClimateChange #Hydrology @reedh2o.bsky.social

💧 Heavy groundwater pumping can worsen sea-level rise and saltwater intrusion. This study by @reedh2o.bsky.social uses machine learning to map groundwater changes in coastal New Jersey—guiding sustainable water management. #Groundwater #ClimateResilience www.frontiersin.org/journals/wat...

🌍💧 Can machine learning predict groundwater levels worldwide? A study by @reedh2o.bsky.social shows that combining U.S. and Denmark data improves groundwater predictions in Denmark—moving us closer to global monitoring. @ioppublishing.bsky.social #Groundwater #MachineLearning

Thanks for the recognition! Honored to be featured as the hydro paper of the day!

Groundwater travels farther and deeper than researchers thought! 🌍💧 This study led by @reedh2o.bsky.social reveals how deep and inter-basin groundwater flows sustain streams, with big implications for water resilience in a changing climate. @naturewaterjnl.bsky.social #Hydrology #ClimateResilience

How long are flowpaths from recharge through groundwater to streams? How connected are watersheds over the CONUS? tldr; much longer and way more connected than we thought. New paper in @naturewaterjnl.bsky.social with Chen Yang and Laura Condon @igwmc.bsky.social www.nature.com/articles/s44...

AGU24 was an amazing time to explore groundwater research! 💧From ML applications to a variety of hydrological models, science communication, and education—our IGWMC researchers covered so much! Did you chat with one of us at #AGU24? 🌍🔍 @agu.org @reedh2o.bsky.social

One of the best things about #agu24 is catching up with friends and former group members. This year was no exception! @igwmc.bsky.social #maxwellgroupadventures
