Data Drought and Data Flood

Data Drought and Data Flood

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…

OpenIFS@home: Using citizen science to improve our understanding of weather and hydrological forecasts

OpenIFS@home: Using citizen science to improve our understanding of weather and hydrological forecasts

The history of HEPEX is deeply connected to ensemble forecasting and uncertainty analysis. Indeed, none of us could even imagine a forecast without uncertainties (apart from McFool). One direction of research is to investigate the value in improving forecasts using a coupled system and truly understand the interactions between the atmosphere and the land surface whilst analysing the associated uncertainties. However, any analysis is limited by the resources one has available. To run a large number of ensembles, one would…

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 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…

Nice hydrographs for everyone, from everyone: Introducing eWaterCycle II

Nice hydrographs for everyone, from everyone: Introducing eWaterCycle II

Contributed by Rolf Hut, TU Delft. “Nice hydrographs! Can you now compare your model to ‘that other hydrology groups model’?” The PhD student suppresses the urge to roll her eyes. Her supervisor is asking her to go back into code-hell. That other model is written in Fortran and she works in Python. It took her two months to get the Python model used in her group running in the first place. Realizing she needed to install an obtuse library on…
