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…

Improving forecasting of flooding from intense rainfall through interdisciplinary research

Improving forecasting of flooding from intense rainfall through interdisciplinary research

Contributed by Dr Linda Speight, University of Reading. In England and Wales alone 3 million properties are at risk of surface water flooding. Having spent the past year speaking to a number of experts in the field (see below), I feel confident saying the universal biggest challenge facing everyone involved in forecasting flooding from intense rainfall is communicating the uncertainties around the location and timing of flood events. Whether you are a researcher looking at developing novel ways to visualise…

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…

Risk Communication for Cyclone Early Warning – Do people get the message, and understand what it means for them?

Risk Communication for Cyclone Early Warning – Do people get the message, and understand what it means for them?

Contributed by Bapon Fakhruddin, Senior DRR and Climate Resilience Specialist, Tonkin+Taylor & Co-chair of the Risk Interpretation and Application of IRDR/ICSU Every year, New Zealand is impacted by ex-tropical cyclones (ETCs) – typically, one ETC makes landfall per year, between the months of November and April. As tropical cyclones approach New Zealand, they begin to lose their strength and undergo extratropical transition (ETT). Some of these weather systems are as large as New Zealand’s North Island when considering the full diameter…
