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

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…

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…

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Crowdsourced data for flood hydrology – Interview with flood chasers in France and Argentina

Contributed by MH Ramos, member of the IRSTEA Columnist Team A recent paper published in the Journal of Hydrology has drawn my attention: Crowdsourced data for flood hydrology: Feedback from recent citizen science projects in Argentina, France and New Zealand. The paper deals with the use of information from social media in applied sciences and operations, with a focus on collecting photos and videos  to better assess river flows and to improve flood mapping after severe events. It prompts reflections on the way qualitative and quantitative data can…

The human hydrological model

The human hydrological model

by Marie-Amélie Boucher, a HEPEX 2015 Guest Columnist Very recently, my fellow HEPEX columnist Jan Danhelka discussed the importance of the human forecasters in the whole process of weather and streamflow forecasting. His blog reminded me of a visit I made last year which somewhat challenged my views on flood forecasting. It was a technical tour about water management on Spencer Creek watershed that took place at the end of a conference. And there I met the first (and so far…

Developing a pilot surface water flood forecasting tool for Glasgow and operational use during the Commonwealth Games

Developing a pilot surface water flood forecasting tool for Glasgow and operational use during the Commonwealth Games

Contributed by Linda Speight This year, the 2014 Commonwealth Games were held in Glasgow and everyone in Scotland was keen for it to be a success. Glasgow however has a known history of summer surface water flooding (2002, 2007, 2011, 2012, 2013). The Scottish Flood Forecasting Service (SFFS) is responsible for flood forecasting in Scotland, and we felt that if heavy rain was to occur, our existing surface water forecasting capabilities would not be sufficient to meet the expected briefing…
