We need better topography data for better flood inundation simulation

We need better topography data for better flood inundation simulation

Contributed by Dai Yamazaki. In recent years, technical barriers for executing flood inundation simulation are getting lower and lower, thanks to increasing computational power and increasing availability of satellite observation data. Flood inundation models are now being used for flood risk assessment and monitoring, such as making a flood hazard map at any location in the world and forecasting flood hazard in a real-time manner. The physics equations used in flood inundation models are relatively simple, compared to those of…

An Interview with Rafael Pimentel – Winner of the HEPEX Logo Competition

An Interview with Rafael Pimentel – Winner of the HEPEX Logo Competition

Contributed by Ilias Pechlivanidis. Rafael (also known as Rafa) has been a key member of SMHI’s Hydrology R&D group for about 2 years. I personally got to meet him a year earlier at EGU to discuss about hydrological processes in data-sparse mountainous regions and Spanish reservoir regulations which are quite difficult to describe. However what makes Rafa unique is the multi-dimensionality of his character that can jump from serious to funny and from hydrological world explorer to the winner of…

HEPEX has had a makeover!

HEPEX has had a makeover!

You may have noticed that this website, and the HEPEX social media accounts, are looking a little different. At the HEPEX workshop in February 2018, it was decided that the HEPEX online platforms could do with a bit of an update, and that HEPEX should finally get an official logo.  So a few months ago, we asked for your help to give HEPEX a shiny new logo! The competition received many designs which we put to a public vote before giving…

Skilful seasonal forecasts of streamflow over Europe?

Skilful seasonal forecasts of streamflow over Europe?

Contributed by Louise Arnal, University of Reading & ECMWF Editor’s Note: Don’t miss the brilliant cartoon summary at the bottom of this post! Over recent decades, seasonal streamflow forecasting methods have evolved and diversified, reflecting changes in our scientific understanding of streamflow predictability on seasonal timescales and our increasing computer power. The first operational model-based ensemble seasonal streamflow forecast, called the ESP1,2 (ensemble streamflow prediction), relies on the correct knowledge of the initial hydrological conditions (IHC; i.e. of snowpack, soil…

Workshop Summary: Hydrological Services for Business

Workshop Summary: Hydrological Services for Business

contributed by Shaun Harrigan, ECMWF Over 60 participants ranging from consultancy companies, hydro-meteorological services, (re)insurance, and academia were welcomed at the European Centre for Medium-Range Weather Forecasts (ECMWF) in Reading, UK from the 8th to 9th of May 2018 to meet with the Global Flood Awareness System (GloFAS) development team. They were provided the opportunity to shape the future of GloFAS forecasting products and service provision. GloFAS is part of the Copernicus Emergency Management Service. The first session introduced GloFAS…
