NASA's Earth Observatory estimates two billion people are likely to be vulnerable to flooding by 2050. Cardiff University recognised the need for experts to have access to the most accurate models possible to predict flood risk and safeguard water quality.

There’s a critical need for accurate and reliable models to predict the movement of floodwater, and its contents, in the event of flood defences being breached.

Professor Roger Falconer Director of Hydro-environmental Research Centre

Studying the flows

Researchers led by Professor Roger Falconer sought to develop new models to predict the risk of flooding in rivers and floodplains, and manage demand for water quality.

A model was refined to give accurate solutions for dam breaks and embankment breach flows. The model has been further refined to simulate the effects of flooding in urban environments, treating buildings as impermeable rather than solid to replicate the effect of flooding on built-up floodplains. Further models have included evidence gathered from laboratory experiments on the motion of scaled cars and model people in rivers under flood conditions.

Our Impact

The models have been used to show the viability of Sabah Al Ahmad Sea City - a major coastal waterway development in Kuwait. In Romania, models have been used to map flood risk over 700km of the Siret River and its major tributaries following a major event in 2005 resulting in fatalities. And in the Philippines, the research is helping to map potential flood risk scenarios across the country.
