Background
Managed realignment means altering flood defences to allow land that was previously protected to be flooded as part a wider strategy for managing the shoreline or estuary. It can be a long-term, sustainable option for managing coasts and estuaries.
A review in 2003 concluded that guidance for practitioners on the designing and building managed realignment projects should be improved. This project provided technical guidance based on current good practice.
Outcome
The final report provides information to help designers and managers:
- improve how coastal and estuary managed realignment projects are designed and built
- increase the use of managed realignment while making sure it’s done well
- increase stakeholder confidence in managed realignment as an option for managing floods
- encourage more sustainable design and construction for flood management
- conserve and enhance natural coastal environments
The report covers:
- the objectives of managed realignment schemes
- how to decide whether managed realignment is appropriate for a particular site
- technical guidance on designing and implementing managed realignment schemes
This project ran from 2003 to 2004 at a cost of £97,200.
