HEPEX 2018 Year in Review

HEPEX 2018 Year in Review

In the last HEPEX blog post of the year, we’re taking a look back at our highlights of 2018! This year, we published 36 blog posts, with contributions from HEPEX-ers across the globe.  But first of all, a quick reminder of important HEPEX events coming up soon: The abstract deadline for EGU 2019 (7-12 April, Vienna) is fast approaching – don’t forget to submit your abstract by 10th January! Click here for an overview of hydrological-forecasting-related sessions, and here for information…

Lessons from calibrating a global flood forecasting system

Lessons from calibrating a global flood forecasting system

Contributed by Feyera Hirpa, University of Oxford. Hydrological models are key tools for predicting flood disasters several days ahead of their occurrence. However, their usability as a decision support tool depends on their skill in reproducing the observed streamflow. The forecast skill is subject to a cascade of uncertainties originating from errors in the models’ structure, parametrization, initial conditions and meteorological forcing. The Global Flood Awareness System (GloFAS) is an operational flood forecasting system that produces ensemble streamflow forecasts with…

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…

Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Acqua Alta: Flooding and Flood Forecasting in Venice, Italy

Contributed by Luigi Cavaleri, Institute of Marine Science (CNR), Venice, Italy. Venice is sinking at a rate of 1-2 mm/y. Combined with the present rate of sea level rise, ~3mm/y, this leads to ever more critical conditions for the possibility of flooding. With half of the city now no more than 80 cm above the present mean sea level and a tidal spring excursion of about 1 metre, any small surge will imply flooding in large parts of the city. A…

Hydrological Forecasting at EGU 2019: Time to write your abstract

Hydrological Forecasting at EGU 2019: Time to write your abstract

The sessions for the European Geosciences Union General Assembly (7-12 April 2019, Vienna) have been announced, and we’re excited to see that the Hydrological Forecasting sub-division will have 14 sessions covering a fantastic range of topics, including of course the HEPEX-sponsored Ensemble Hydrometeorological Forecasting session! You can contribute to the advancement of hydrological prediction by presenting your scientific developments, applications, operational approaches and more at EGU 2019 – abstract submission is now open until 10 January 2019, 13:00 CET. Why…
