Sussex Wildlife Trust has been working in partnership with the Environment Agency and Woodland Trust undertaking Natural Flood Management within the Ouse Catchment since 2012. This initially started as the innovative pilot project Trees on the River Uck (TrUck), which was expanded to the whole 605 square kilometres of the Ouse Catchment in 2014, as well as being renamed the Sussex Flow Initiative. Two years later the partnership was joined by Lewes District Council. In 2018 the project expanded to delivered Natural Flood Management within the Powdermill Catchment in East Sussex.
Sussex Flow Initiative is working with landowners, local communities and others to naturally slow down and store flood water in the landscape through advocacy and delivery.

We also support Sussex Flow Projects on the Cuckmere and Combe haven. In 2019-20, this project also achieved some great stuff for Natural Flood Management. SFI Powdermill Annual Report 2019 20
Natural Flood Management (NFM) uses natural processes and landscapes to help reduce flood risk and to increase resilience to drought. The techniques we use deliver multiple benefits for people and wildlife. Natural Flood Management techniques include :-
- Re-wooding landscapes to reduce flooding and run off
- Planting hedgerows across slopes to capture rain
- Using permeable surfaces and rain gardens to store run off
- Restoring river channels and meanders
- Restoring natural washlands
- Natural erosion control
- Reversing drainage of moorland, woodland and heathland
- Using and managing Natural Woody Material in watercourses
- Increasing surface water storage i.e. in ponds
- Recycling roof and greywater run-off
- Reducing (sub surface) land drainage
The Government has produced a range of Guidance on Working with Natural Processes to reduce Flood Risk, including a Series of useful one page Summaries on different NFM techniques such as leaky dams.
