www.drought.ch – Early recognition of critical droughts in Switzerland

www.drought.ch – Early recognition of critical droughts in Switzerland

In recent years Switzerland experienced some unprecedented drought situations. At the political level solutions have been requested for early recognition of hydrological droughts. A prototype information platform has been developed to guide water resources management during situation where water resources drop below critical levels. www.drought.ch has been developed after a two-stage dialog with stakeholders from different sectors including hydropower, forestry, agriculture and river navigation. Since June 2013 the platform is presenting daily updates information on anomalies in precipitation, streamflow, lake…

Testbeds in HEPEX: lessons learned and way forward

Testbeds in HEPEX: lessons learned and way forward

Contributed by Maria-Helena Ramos and Andy Wood How were testbeds initially defined? The testbed activity was first summarized in the 2006 Implementation Plan for The Hydrological Ensemble Prediction Experiment (HEPEX) (Wood et al., 2006). In the first two HEPEX workshops (Reading in 2004 and Boulder in 2005), it was decided that HEPEX’s projects and activities would be organized in pilot ‘testbeds’ (download here the proposal from the Boulder 2005 workshop). “The test beds are collections of data and models for specific…

Intercomparison of streamflow post-processors Post-Processing hydrologic model simulations (Phase 1)

Intercomparison of streamflow post-processors Post-Processing hydrologic model simulations (Phase 1)

Contributed by James Brown, Nathalie Voisin and Maria-Helena Ramos The experiment was launched in June 2012 and the first results are currently being anlaysed. See our poster presented at EGU 2013: Posters HS4.3/AS4.20/NH1.13 – Ensemble hydro-meteorological forecasting for improved risk management: across scales and applications Our aims is: To establish the advantages and disadvantages of different post-processing techniques and strategies when accounting for hydrologic uncertainty To foster ongoing collaboration among the HEPEX participants on the topic of streamflow post-processing and…
