GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

Contributed by Shaun Harrigan, ECMWF. In an ideal world we would have river discharge measurements for every river spanning many decades and updated in real time. We all know this is very far from reality with severe gaps in the global observing network (Lavers et al., 2019), and provides a fundamental challenge for hydrological monitoring and forecasting. A way forward pioneered in the field of meteorology and climate is to optimally combine available in situ and satellite Earth system observations…

Flash flooding is a serious threat in the UK – here’s how scientists are tackling its prediction

Contributed by Christopher J White, University of Strathclyde ; Michael Cranston, RAB; Laura Kelly, University of Strathclyde ; Linda Speight, University of Reading. 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…

Protect your city from floods with the IMPREXive game

Protect your city from floods with the IMPREXive game

We all know that the HEPEX community loves games and interactive challenges. We have already six games available in our Resources page. One of these games (“Pathways to running a flood forecasting centre: an adventure game”, by Louise Arnal & colleagues) has inspired a very nice online game developed by Arctik, a public relations, communications and evaluation consultancy, within the EU Horizon 2020 Imprex research project. Do you want to play it? In the game, you’ve landed a job as…

Improving Hydro-Met services in developing countries

Improving Hydro-Met services in developing countries

Contributed by Florian Pappenberger, ECMWF.  It is in the DNA of every HEPEX-er to believe that better hydrological forecasts contribute to human wellbeing and economic prosperity. We also know that the forecasts themselves are not enough and need to be accompanied by adequate warnings and receptive civil societies (amongst many other factors). A particularly important role in ensuring that a forecast has impact, falls to the National Hydro-Meteorological Services (NMHSs). A recent guide by the World Bank focuses on the…
