Bristol and NASA call for international co-operation on global-scale flood model
20 March 2014
Industry, governments and humanitarian agencies should come together to support the development of a global flood model, researchers say.
Professor Paul Bates and Dr Jeff Neal of the School of Geographical Sciences along with colleagues at NASA Jet Propulsion Lab have issued a call in the journal Nature for international co-operation to develop a high resolution and accuracy global Digital Elevation Model (DEM) in order to strengthen protection against damaging floods.
By 2050 worldwide annual losses due to flooding are predicted to reach US$1 trillion, yet current global DEMs cannot resolve the detail of terrain features that control flooding and hence do not allow flood risk to be predicted accurately in many countries.
A global-scale DEM would have an enormous impact on finance (such as flood re-insurance), humanitarian services (such as disaster relief) and scientific research.

The Cabot Institute
The Cabot Institute carries out fundamental and responsive research on risks and uncertainties in a changing environment. It drives new research in the interconnected areas of climate change, natural hazards, water and food security, low carbon energy, and future cities. Its research fuses rigorous statistical and numerical modelling with a deep understanding of social, environmental and engineered systems – past, present and future. It seeks to engage wider society by listening to, exploring with, and challenging its stakeholders to develop a shared response to 21st Century challenges. Find out more at www.bristol.ac.uk/cabot
