A new dataset on the water quality in Swiss river catchments is now available. CAMELS-CH-Chem incorporates up to 40 water quality parameters for 115 Swiss catchments between 1981 and 2020 💡

The last weeks we spent preparing the AWS for our @cryoscope.bsky.social field campaigns in Ladakh - apologies to my office mates for the mess 🙃 Everything is working & the shipment arrived in India. We are excited to start our field campaign soon, stay tuned for updates! @harshberia.bsky.social

Great start of our @cryoscope.bsky.social & @hyclimm.bsky.social collaboration in the beautiful Dischma Valley in Davos. Looking forward to join forces to explore the runoff generation processes in high Alpine environments together!

Last week, James Kirchner, @harshberia.bsky.social and @mfhydro.bsky.social visited us in Davos to discuss the ongoing field study of river water temperature and their study on river isotopes! Thanks for the nice discussions!

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 recharge. onlinelibrary.wiley.com/doi/10.1002/... @canopyinclouds.bsky.social @harshberia.bsky.social @scottallenunr.bsky.social

Successful 3-hr stream sampling during a major weekend storm, will be interesting to trace its signatures in streamflow isotopes. We installed a rain sampler and hosted Zuosinan Chen from @unioulu.bsky.social

Five years ago we started with first installations and sampling at our WaldLab Forest Experimental Site! 🌲 💧 Thanks to all the amazing people that supported me in the last years, enabled us to do exciting research and to @ethz.ch for celebrating the anniversary with this nice article! 🥳

Five years ago, an experiment began at ETH Hönggerberg: researchers set up an outdoor laboratory in the forest. They used sensors positioned in trees, the soil and in a stream to study water dynamics. ETH News accompanied the head of the experiment, Marius Floriancic. ethz.ch/en/news-and-...

To what extent do beech 🌳 and spruce 🌲 trees shift their water uptake to deeper layers in dry periods? Can deep roots alone sustain full tree transpiration? Find out out more in Stefanos excellent PhD paper in Tree Physiology, based on root measurements @waldlabor -> doi.org/10.1093/tree...

We invite contributions on experimental and modelling studies that present methodological developments and applications of isotope tracers to improve our process knowledge of water and nutrient fluxes between the subsurface, plants and the atmosphere, across different scales.

How much of groundwater seepage & mixing occur around main-river knickpoints? We conducted extensive synoptic sampling, mixing & groundwater modelling to learn more about this in our recent #AGU #GRL publication! So happy to see this paper out: agupubs.onlinelibrary.wiley.com/doi/10.1029/... 🥳

How much of streamflow in Swiss & Austrian Alpine rivers is younger than 1 month? How is this related to catchment characteristics & hydro-climatical variables?

We answered these questions in our recent @eurogeosciences.bsky.social publication together with BOKU

This is also a proud supervisor moment for myself, I had the honor to guide Maria from first results in her BSc thesis, through hours of fieldwork & data evaluation to the acceptance of an awesome paper! Very well done Maria, it was a pleasure working with you! 🌲🌳

To what extent do trees affect nutrient composition of precipitation reaching forest soils? Our recent
publication from WaldLab Zurich led by Maria Grundmann shows seasonal enrichment patterns & we assess potential drivers based on data from 222 rainfall events.

Last week we had the pleasure to host an international group of students Waldlabor Zürich for the 1st edition of the @ethzurich.bsky.social & EPFL Ecohydrology Summer School! Such an amazing group of people, I really enjoyed showing you around & introduce our latest results and sampling efforts!

Thanks to an @ethzurich.bsky.social Innovedum Fund we were able to update our hydraulic lab equipment -> hands-on weir experiments in mini-flumes, a pipe airflow kit & implement data evaluation in Jupyter Notebooks! A huge effort of all staff involved, but totally worth it! 🌊😍 #teaching
