The 2018 and 2019 droughts are still fresh in our memory, when extended areas in Europe suffered, once more, from extreme drought. Climate projection studies show that drought very likely will become more frequent. Similar to the 2015 drought (Van Lanen et al., 2016), impacts of the 2018 drought in Europe were tremendous and affected many sectors. For example, farmers…

It’s becoming a familiar scene on the news: sodden British people wading through streets up to their knees in flood water. From Stirling to Sheffield, many parts of the UK in 2019 felt the impact of severe surface water flooding – often referred to as flash flooding – that followed torrential rain. As the climate changes and the…

Contributed by Ilias Pechlivanidis and Marie-Amélie Boucher. Marie-Amélie Boucher has been a HEPEXer since 2007, with a strong involvement in HEPEX-related events, i.e. organizing committee member of the HEPEX 2016 workshop in Québec, and lecturer of the hydrological forecasting course for the Early Career Scientists (ECS) at EGU2017 in Vienna and IAHS 2019 in Montréal, and others. On a scientific level, she is one of the members that brings knowledge to the community on Nordic hydrological processes and forecasting practices…

Hydrometeorological forecast verification: the detail matters!

Hydrometeorological forecast verification: the detail matters!

Contributed by Seonaid Anderson, CEH.  Spending time and effort developing a novel hydrological ensemble prediction system, demonstrating its value, comparing with existing systems, justifying all that effort… there are many reasons why we verify our ensemble prediction systems. Before we dive into the number crunching, a few obvious questions need to be asked. What period to use for evaluation? This is often as long as possible, while maintaining relevance to the current application and subject to the usual computing constraints. What…

Contributed by Mark Trigg*.  It’s hot, and very, very dry. The rains have failed, and the animals are dying. Around the table people are concerned that it will be people dying next. The cycle seems to repeat every 10 years and the response is exactly the same, every time – we must do something and save lives. “Drill more boreholes and put in big pumps and generators”, someone cries, “no matter the cost!”. A timid voice rises above the ongoing…
