We have a PhD position at @ETH for "Tracer-aided ecohydrological modelling in snow-dominated ecosystems"
We start evaluations on **15th October**. Please spread the word

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

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

Winter precipitation is the major source of summer tree transpiration @waldlabor ! 🌲💦🌳Read more about seasonality signals in soil & xylem waters in our recent @EcohydrologyEds publication: onlinelibrary.wiley.com/doi/… @ScottTAllen1 @JamesWKirchner @KirchnerLabETH

By how much do throughfall & stemflow differ isotopically from incoming precipitation across seasons? New @waldlabor publication out in HP showing (relatively small) offsets in forest precipitation isotopes: onlinelibrary.wiley.com/doi/… @KirchnerLabETH @usys_ethzh

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 @EGU_HESS reporting some exciting findings from our @waldlabor field site! 🥳💦

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 @eellhhaammm et al geo.uzh.ch/en/events/feature…

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 @wberghuijs @jprancevic @JamesWKirchner

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/s41561-0… @jprancevic @JamesWKirchner @kirchnerlabeth @vu_science
This week @KirchnerLabETH said goodbye to @JLAKnapp, who after 2.5 years in Zurich is heading for bigger & better things @durham_uni where she will be an assistant professor. Thanks for your time with us, and all the best in your new job @JLAKnapp

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

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

Our paper on event-scale cQ relationships is published in @EGU_HESS! 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.
