Why do trees preferably transpire winter precipitation? 🌳💦 In our latest commentary we argue that it's not a big surprise but the effect of seasonal differences in soil water recharge. https://t.co/HCNhhSW7tc

[UMass Amherst @UMassAmherst]

In engineering, there’s always an ideal—but real-world design means innovating under imperfect conditions.

UMass Amherst hosted the ASCE Northeast Student Symposium, where students built & raced concrete canoes 🛶

[AGU Catchment Hydrology @AGUCatchHydro]

The #AGU Catchment Hydrology TC is spotlighting key catchments from the HYP special issue, Research and Observatory Catchments: The Legacy and the Future!
🧵 Today, we kick off with “Jonkershoek: Africa's oldest catchment experiment—80 years and counting”!

[Enrico Bertuzzo @enricobertuzzo]

I have not been on Twitter for a while...but I give it another shot for promoting the latest chapter of @GiuliaGrandi dissertation, now published in WRR, where we look at how transit time affects the concentration and the quality of DOC in the streamflow.

[AGU's Eos @AGU_Eos]

It's #WorldWaterDay!

Water your plans for the day? We'll be diving into some Eos stories to celebrate: https://t.co/bC6tcmXW4a

Colin finished his two-month visiting professorship in IIS UTokyo. We had a very exciting academic+cultural interactions, and learned and enjoyed a lot!!
Thanks Colin for choosing Yamazaki lab for your sabbatical place.

If you're interested in all the ways that lake ice influences ecosystems and humans, be sure to check out this manuscript! [SNL Stefon voice]] It's got everything! Winter recreation, carbon cycling, lake effect snow, and even a section on shoreline erosion.

[Fabian Quichimbo @flquichi]

Thrilled to announce my latest work! In this study, we explored the variables that control mean transit times (MTT) and their distribution (TTD). How can transit time be used as a coherent catchment descriptor? 👇

Very happy to host Michail during his stay at our lab !! He is doing a terrific job at testing this DIY autosamplers for rain and river waters developed by Benjamin FIscher and himself - we'll be deploying them in our #Suyuque #Catchments soon !
