As the project officer for the Sussex Flow Initiative (SFI) I was very pleased to meet with members of TTL recently to discuss ways that Natural Flood Management (NFM) can help reduce flooding across the Ouse catchment and help with flood resilience for Lewes town. SFI is hosted by the Sussex Wildlife Trust in partnership with the Woodland Trust and the Environment Agency – a partnership that started in 2012 with the Trees on the River Uck (TrUck) pilot project.
|NFM is an approach to flood mitigation that’s been researched, developed and implemented relatively recently and which works alongside man made flood defences (rather than replacing them), harnessing natural processes to slow and store more water upstream to reduce the peak of flooding downstream. Natural additions such as floodplain woodland, across slope hedgerows and shelter belts or leaky dams have all been shown to help to slow the flow of water, making the landscape better able to cope with heavy rainfall and reducing the power and magnitude of flooding. With over 50 different NFM techniques to choose from, these natural enhancements can be tailored to fit a given site, providing a range of further benefits for wildlife, water quality and river health.
