Survey results: views and opinions about Hepex and hydrological forecasting

July 18, 2018 Maria-Helena Ramos Comments 0 Comment

Contributed by Maria-Helena Ramos At the beginning of the year, we launched a short online survey to gather some views and opinions about Hepex and start a discussion on the future of Hepex: how should the community continue its efforts? What should Hepex be in 10 years’ time? During the 7th International Hepex Workshop in Melbourne we had an interactive poster that complemented this survey and collected some more views and opinions from the participants of the workshop. Below you…

What are the challenges for HEPEX over the next decade?

March 21, 2018 Fredrik Wetterhall Comments 1 comment

The question sounds grand and may be a bit difficult to give a simple answer to, but that was the question put forward to the participants at the HEPEX workshop in Melbourne in February. HEPEX was founded as an initiative in 2004 with the goal of bringing the hydrological and meteorological communities to “demonstrate how to produce reliable …hydrological ensemble forecasts that can be used to assist the water resources sector to make decisions that have important consequences for the…

The future of HEPEX: 100 years from now

June 13, 2014 Florian Pappenberger Comments 7 comments

Contributed by Florian Pappenberger and Maria-Helena Ramos Soon we will be celebrating 10 years of HEPEX and other posts have already highlighted what we have achieved. Our Science and Implementation plan also lists past achievements and looks into the immediate (3-5 years) future. The scientist and fiction writer Isaac Asmiov was brave (or foolish) enough to look what may happen 50 years in the future (for details see here). For 2014, he predicted: electroluminescent panels, new tools of communication, new…
