How do solute concentrations vary as function of streamflow during hydrologic events? Find out from our #shareEGU20 display (session HS 2.3.2 on water quality time series): meetingorganizer.copernicus.org/EGU2020/EGU202… Please check it out and comment!

UPCOMING EVENT! Join Wouter Berghuijs for a webinar on the patterns and processes of catchment hydrology. 1500 (BST), Fri 22 May Register for the event here: forms.gle/dJDbL8uGGubwWQ… SoGE, University of Oxford #hydrology #catchment #water

Our paper on event-scale cQ relationships is published in HESS Journal! We investigate the variability of cQ relationships during rain events and how event patterns differ from long-term cQ patterns, &we link the observed variability to event characteristics. hydrol-earth-syst-sci.net/24/2561/2020/h…

Wondering about the age distribution of Alpine groundwaters? In the last weeks we Kirchner Lab ETH took bedrock groundwater samples at multiple tunnel (construction) sites across the European Alps. A huge thank you to everyone supporting our field campaigns! D-USYS@ETH

Learn about 'Global controls of river network geometry' with Seybold Hansjörg & Berghuijs Wouter Reinier. Today's Source-to-Sink (S2S) chat at 14:00 BST / 9 AM EDT. Join live at youtube.com/channel/UCPQZB…

I spent the day collecting groundwater samples in #Alptal. I will definitely miss this place!

We are hiring! Several open postdoctoral research positions in catchment #hydrology, #ecohydrology, and #geomorphology at Kirchner Lab ETH. For more info: pes.ethz.ch/the-group/open…

This week Kirchner Lab ETH said goodbye to Julia Knapp, who after 2.5 years in Zurich is heading for bigger & better things Durham University where she will be an assistant professor. Thanks for your time with us, and all the best in your new job Julia Knapp

Tectonics controls how a river's gradient changes as it descends along its course. Most river profiles appear largely unaffected by climate and instead reflect the slow dance of Earth’s crust. nature.com/articles/s4156… @jprancevic James Kirchner @kirchnerlabeth @vu_science

Our latest paper led by Hansjörg Seybold shows that longitudinal profile of rivers are predominantly controlled by #tectonics and erosional processes and are mostly independent of climatic effects Wouter Berghuijs @jprancevic James Kirchner nature.com/articles/s4156…

River networks are striking features engraved into the surface of the #Earth. What erosional mechanisms created these distinctive geometric signatures? It's #groundwater that shapes river network branching angles, says a new paper by Elham Freund et al geo.uzh.ch/en/events/feat…

How much recent precipitation can be found in different depths of the subsurface and which of these waters contribute to streamflow? New pre-print available HESS Journal reporting some exciting findings from our Waldlabor Zürich field site! 🥳💦

By how much do throughfall & stemflow differ isotopically from incoming precipitation across seasons? New Waldlabor Zürich publication out in HP showing (relatively small) offsets in forest precipitation isotopes: onlinelibrary.wiley.com/doi/full/10.10… Kirchner Lab ETH D-USYS@ETH

Winter precipitation is the major source of summer tree transpiration Waldlabor Zürich ! 🌲💦🌳Read more about seasonality signals in soil & xylem waters in our recent Ecohydrology publication: onlinelibrary.wiley.com/doi/full/10.10… Scott Allen James Kirchner Kirchner Lab ETH

How much of streamflow in Swiss & Austrian Alpine rivers is younger than 1 month? How is this related to catchment characteristics and hydro-climatical variables? We answered these questions in our recent @EGU HESS publication in collaboration with our friends SoPhy BOKU

Using continuous 3-year soil water isotope sampling in different depths & hillslope locations @Waldlabor we reveal the mysteries of streamflow generation. Thanks HESS Journal for highlighting this huge (still ongoing) sampling effort!
