The RRC Manual of River Restoration Techniques aims to help river managers identify potential restoration techniques for use in river restoration and sustainable river management. It now includes 64 case examples which can be downloaded as PDFs at 35 sites across the UK. The panel ‘Tabular overview of techniques’ opens a simple list of all case examples with easy access PDF links for users accessing information using mobile devices.
How was the manual updated
- Existing case examples were updated where possible explain how the technique has performed and the site evolved.
- 17 new case examples were added to the 47 existing case examples
- A new section‘How to use this Manual’ has been added.
How do I use it?
Users are encouraged to read the ‘How to use this Manual’ section first to learn more about the resource.
- Case examples range from large-scale civil engineering projects through to small-scale interventions. They include details of the restoration techniques used illustrated with engineering section drawings, diagrams and photographs. Users can search by river name, site designation, restoration technique or Water Framework Directive (WFD) mitigation measure or use the interactive map.
are also provided. The Manual is now an online-only resource; however the RRC are able to print off hard copies with a small charge for p&p. Alternatively you can download each version of the Manual as one PDF (note: low-resolution only) to inform your project’s design and development.
Your chance to comment
The Manual has been put together with the support of contacts involved in the projects. However if you would like further explanation or to leave feedback, contact RRC.

- Alteration of channel bed (within culvert)
- Improve floodplain connectivity
- Increase in-channel morphological diversity
- Managed realignment of flood defence
- Preserve and, where possible, restore historic aquatic habitats
- Removal of hard bank reinforcement / revetment, or replacement with soft engineering solution
- Remove obsolete structure
- Re-opening existing culverts
- Set-back embankments (a type of managed retreat)
- Appropriate channel maintenance strategies and techniques e.g. minimise disturbance to channel bed and margins
- Retain marginal aquatic and riparian habitats (channel alteration)
- Sediment management strategies (develop and revise) which could include a) substrate reinstatement, b) sediment traps, c) allow natural recovery minimising maintenance, d) riffle construction, e) reduce all bar necessary management in flood risk areas
- Operational and structural changes to locks, sluices, weirs, beach control, etc
- Preserve and, where possible, enhance ecological value of marginal aquatic habitat, banks and riparian zone
- Appropriate techniques to align and attenuate flow to limit detrimental effects of these features (drainage)
- Restore form and function (channel and channel migration zone)
- Restore form (floodplain)
- Re-connect floodplain (remove or set back embankments)
- Remove structure (culvert, bank protection etc)
- Make flow regimes more natural
- Riparian planting
- Channel form and flow type & floodplain connectivity
- Barriers to connectivity
