Project summary

Edit project overview to modify the project summary.


The project aimed to restore natural processes along the Pow Burn between Farnell and Powmouth. The river had been straightened and extensively dredged. Arable land use encroached extensively on the river corridor. Restoration measures included 1) Restoration of an inset riparian corridor by moving back embankments and creating a multi stage channel with the aim of encouraging frequent out of channel flow supporting natural riparian habitats 2) Installation of flow deflectors to create hydraulic diversity driving geomorphic adjustment of the channel form. 3) Excavation of backwater channels and flood relief channels to take pressure off the main channel and increase ecological interactions between the river and riparian zones. The project was led by the Esk Rivers and Fisheries Trust (ERFT) and funded by the SEPA Water Environment Fund (WEF)
