Previsico's Flood Forecasting Technology

State-of-the-art flood forecasting technology

Our state-of-the-art flood forecasting technology was developed following two decades of research and development at Loughborough University, together with key stakeholders including the Environment Agency and the UK Cabinet Office.

Our forecasting technology uses live modelling to produce actionable forecasts which enable people and organisations to proactively mitigate flood impacts. Uniquely, these forecasts are remodelled every 3 hours and updated using the very best weather data, in partnership with IBM’s Weather Company.

 This 2D flood simulation software uses high-quality topographic and hydrological data to produce fast and accurate representations of flow routing across flood plains including surface water, river, and coastal flooding. The model is broadly outlined in Yu and Lane (2006a,b).

 Further research that underpins the technology was published in internationally respected journals over two decades, including Nature Sustainability. These publications can be found below.

Coverage

Our services are currently available across the whole of the UK and widely available across the USA. The service can be set up anywhere globally on request. Existing other coverage for the service includes regions in China, Indonesia, Thailand, Japan and Kenya.

WE HELP MITIGATE FLOOD RISK

Most flood impacts are avoidable with the right early warning systems. Our cutting-edge modelling technology predicts floods which are missed by traditional approaches. We work with insurers, businesses and governments to help mitigate the growing devastation caused by flooding by delivering actionable warnings, data and analytics to enable proactive measures to be taken.
