25-year vision set out by flood hydrology roadmap

A flood hydrology roadmap, released on 22 March 2022, sets out a vision to help scientists and practitioners better predict future flood events and improve flood resilience across the UK.

The roadmap, which brings together views of more than 100 experts, will improve hydrological data, models and science, which can be used to inform how we adapt to flood risk for our rivers, surface water, groundwater and reservoirs.

These models will underpin flood risk management for decades to come, with benefits to areas including:

  • design and maintenance of flood defences;
  • national and local flood risk assessment and mapping;
  • design and operation of flood forecasting and warning schemes;
  • design and operation of sustainable drainage systems; and
  • understanding the impact of climate change on future flood risk.

The roadmap will also allow us to understand the impact of climate change on flood risk and will support modelling of past and future climate change impacts.

The Environment Agency has already secured £6.9 million over six years to start delivering on the roadmap and is working with the following to identify routes to further funding:

Dr Sean Longfield, Lead Scientist on Flood and Coastal Risk Management Research for the Environment Agency and author of the report, said: "This roadmap provides us with a fantastic opportunity to better understand the science behind flooding and will be an invaluable tool in helping us understand future flood risk".

"The Environment Agency is working hard to ensure recommendations from the roadmap are followed up on so we can develop the next generation of flood hydrology knowledge, methods, models and systems that will underpin flood and coastal risk management for decades to come".
