Project summary

Edit project overview to modify the project summary.


Local Levy funding (~£350,000) was allocated by the North East Regional Flood and Coastal Committee (RFCC). The Environment Agency used ~£250,000 to commission Newcastle University to monitor the catchment, conduct hydraulic modelling, design run-off attenuation features (RAFs), engage with landowners and the community, and appoint specialist contractors to deliver the interventions. The remaining funds were used to repair a damaged wall on the bridge in Belford village and to improve the drainage network in the village. (Note that only 2 landowners were willing to take part at the early stages.) Monitoring of individual RAFs has shown that they are able to have a significant impact (up to 10% reduction) on the flood peak in small to medium events, but that they were overwhelmed by larger events (by filling with floodwater during the rising limb of the hydrograph during observed storms). The RAFs have also provided multiple benefits including sediment capture and water quality improvements.
