Nice hydrographs for everyone, from everyone: Introducing eWaterCycle II

Nice hydrographs for everyone, from everyone: Introducing eWaterCycle II

Contributed by Rolf Hut, TU Delft. “Nice hydrographs! Can you now compare your model to ‘that other hydrology groups model’?” The PhD student suppresses the urge to roll her eyes. Her supervisor is asking her to go back into code-hell. That other model is written in Fortran and she works in Python. It took her two months to get the Python model used in her group running in the first place. Realizing she needed to install an obtuse library on…

Can hydrological forecasting contribute to Science & Art projects?

Can hydrological forecasting contribute to Science & Art projects?

Contributed by Maria-Helena Ramos and Louise Arnal. In 1991, L. D. James starts his book chapter stating that “[i]n content, hydrology is a science; in practice it is an art”. The discussion that follows reflects on the links between science and practice at the time of writing, questioning how much “the art of hydrology [was becoming] increasingly outdated” and highlighting the “pressure for new methods” to keep on securing decision makers in water resources planning with “sound scientific information for…

23 (+1) unsolved questions in hydrology

23 (+1) unsolved questions in hydrology

Contributed by Bettina Schaefli Have you heard about the “23 unsolved problems” initiative of IAHS, in reference to the 23 unsolved problems of Hilbert? After the launch of this initiative in November 2017, the web-based discussion culminated in a round of brainstorming at EGU 2018 and in a voting process at the Vienna Catchment Science Symposium. Personally, I did not contribute any question at the discussion stage. I simply could not think of a question that relates to observed phenomena,…

An invitation: help HEPEX program apps to teach the value of probabilistic forecasts

An invitation: help HEPEX program apps to teach the value of probabilistic forecasts

Contributed by Florian Pappenberger, Andy Wood, Maria-Helena Ramos, Schalk-Jan van Andel, Louise Crochemore, and Louise Arnal This is a blog for people who usually do not read this blog. This is a blog which asks for help so that our learning and teaching games and tools become more useful and widespread. This is a blog hoping that we can find some enthusiastic volunteers. The more people know how to use probabilistic forecasts, the better their decisions and the lower the…

Making connections through HEPEX – A CSIRO experience

Making connections through HEPEX – A CSIRO experience

By QJ Wang, Andrew Schepen, David Robertson, James Bennett, Durga Lal Shrestha, Yong Song and Tony Zhao members of the CSIRO Columnist Team HEPEX has a reputation as a strong community of like-minded, supportive researchers and practitioners who are collectively bent on significantly advancing the science and applications of ensemble hydrological forecasting. HEPEX provides a unique forum where meeting people and exchanging ideas has the very real potential to open up new, exciting collaborative research opportunities. Indeed, this has been the…
