Bridging the gap between forecasters and operational hydrologists: an OzEWEX summer institute project

Bridging the gap between forecasters and operational hydrologists: an OzEWEX summer institute project

Contributed by Melanie Loveridge, Bex Dunn and Yiling Liu How often do we assume that we understand the users’ needs, which may later be proven untrue? At the recent OzEWEX Australian Climate and Water Summer Institute – held in Canberra, Australia – we got the chance to bridge the gap between forecasters and operational hydrologists. Fifteen of us were invited to the OzEWEX summer institute, which provides early career researchers the chance to see the current and emerging data and…

Which scales matter for water resources management?

Which scales matter for water resources management?

Contributed by Andreas Hartmann, Axel Bronstert, Bettina Schaefli The discussion about which scale is the most relevant for water resources management is an increasingly important debate of hydrological modelling principles over the last decade. The session “(Ir‑)relevant scales in hydrology: Which scales matter for water resources management?” convened at this year’s EGU General Assembly 2017 tried to put some new light (and fire) into this ongoing debate. Solicited speakers representing the plot scale, hillslope and catchment scale, and the large-scale…
