Diving deep into Singapore's water cycle! 💦 From urbanized areas to tropical forests, we've set up experimental catchments across Singapore with friends @ NUS to unravel the hydrological response of these diverse landscapes (incl. water retention in tropical litter layers & isotope sampling)

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 💡

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!

A 4-year EU-funded research project uniting 19 partners across 8 countries to better understand snow, glacier and permafrost processes - how they respond to climate change, and how these shifts affect downstream hydrological and biogeochemical cycles.
