Dear IAHS member,

The IAHS Panta Rhei Working Group is producing a series of opinion papers in Hydrological Sciences Journal. For the paper  "The role of experimental research in hydrological sciences - current state, challenges, needs and potentials" we decided to do something different. Instead of the opinion paper reflecting the authors' opinion we want it to reflect how the community feels about this topic.

We would like to hear your opinions, independent of whether you are a modeller, data miner or experimentalist.  It would be great if you could take 10 minutes to complete the survey we prepared.  You can find it here:  https://www.soscisurvey.de/hydrology/ 
(Do it right now - don't put it off... the survey is only open until March 24th.)

And please - pass this link on to anybody who might be interested!

Thank you very much for your help,
Theresa Blume, Ilja van Meerveld, Markus Weiler
