Details

This project has developed methods and guidance to address the need for realistic planning scenarios that account for the risk of widespread flooding across England and Wales, flooding from multiple sources (river, surface water and sea) and the potential impacts.

The outputs of the project have:

  • highlighted the scale of the risk of flooding to England and Wales
  • changed the representation of flood risks for the public facing National Risk Register (NRR) and the Cabinet Office’s National Risk Assessment (NRA)
  • helped inform the National Flood Resilience Review (NFRR) and are being taken forward via that route. They will allow central government, emergency planners and responders to review their planning assumptions, emergency response and mutual aid capabilities, to increase the England and Wales preparedness for widespread flooding.

The Multivariate Event Modeller (MEM) tool was updated and openly published in 2024. To contribute to developing the code, please use the GitHub repository
