Pre-, post-processing or both?

by Marie-Amélie Boucher, a HEPEX 2015 Guest Columnist Do you think it is better to pre-process the meteorological forecasts, to post-process the hydrological forecasts or to do both? Why? Following this blog about future directions for post-processing research, this challenge was … Continue reading

Analogues are the new deterministic forecasts

by Marie-Amélie Boucher, a HEPEX 2015 Guest Columnist According to Krzysztofowicz (2001), “Probabilistic forecasts are scientifically more honest [than deterministic forecasts], enable risk-based warnings of floods, enable rational decision making, and offer additional economic benefits.” More than 10 years later, I … Continue reading

On the life and death of hydrologic models

 by Marie-Amélie Boucher, a HEPEX 2015 Guest Columnist During the 1950-2000 period, a very large quantity of hydrologic models of all varieties were created due to a rapid increase of computational capacities (Roche et al. 2013). Now, on the one … Continue reading

From operational hydrological forecast to reservoir management optimization

Contributed by Marie-Amélie Boucher The interaction between end-users and researchers has long been a central preoccupation of the HEPEX community (see, for instance, this post and this announcement). The recent workshop on operational hydrological forecasting and reservoir management optimisation that … Continue reading

On the economic value of hydrological ensemble forecasts

Contributed by Marie-Amélie Boucher, Maria-Helena Ramos and Ioanna Zalachori It is often assumed that probabilistic forecasts should lead to better water and risk management through increased benefits (economic or not) to users in their decision-making processes. Most often, this assumption … Continue reading
