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…

Hydrological forecasting at EGU 2018 – what not to miss next week!

Hydrological forecasting at EGU 2018 – what not to miss next week!

The EGU 2018 Annual General Assembly will take place next week, from 8–13 April 2017 in Vienna as usual. The HEPEX community will be represented in many ways, and below you will find a quick guide to the most relevant sessions for hydrometeorological forecasters throughout the week. The sub-session on hydrological forecasting consists of 5 oral and poster sessions and 1 pico session. Get the EGU app now and tag the sessions! The very first day will kick off with…

Understanding public responses to flood warnings

Understanding public responses to flood warnings

Contributed by Michael Cranston, RAB Consultants, Scotland The Winter 2015 floods in the United Kingdom and Ireland led to severe and widespread flooding for many communities.  The introduction of storm naming by the Met Office and Met Eireann the same year has since led to the names of Desmond, Frank and Eva becoming synonymous with the flooding that was experienced during that winter. Storm Desmond (5 December) brought major flooding to Cumbria and southern Scotland with a new 24-hour UK…

Developing and running an ensemble prediction system – Interview with Jutta Thielen-del Pozo

Developing and running an ensemble prediction system – Interview with Jutta Thielen-del Pozo

Posted by Maria-Helena Ramos (IRSTEA) I met Jutta Thielen-del Pozo in 2005, when I went to the JRC in Ispra, Italy, to take a post-doctoral position. I had been doing research in hydrology for some time, but I didn’t know anything about ensemble predictions when I joined her team. They were developing the European Flood Awareness System (EFAS) and the first tests using weather ensemble predictions to issue EFAS warnings were just starting. I was fortunate enough to count with…

Flood memory and historical marks of high waters

Flood memory and historical marks of high waters

Contributed by Maria-Helena Ramos (Irstea, France) Last year, the Hepex Portal published a blog post by Richard Davies from floodlist.com about the UK and Ireland floods in December 2015 and January 2016. When navigating through the floodlist website, I found a page dedicated to flood and high water marks (here). I have always found these marks indicating the level reached by the waters of a river (or any other waterbody) after a flood event to be fascinating. It is not…
