Salix’s River Dulais project demonstrating the use of large woody debris (LWD) is now ten years old and has been included in the manual of River Restoration Techniques.
The RRC manual 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 River Dulais (Afon Dulais) is a tributary of the River Towy and is an important spawning habitat for migratory fish. Unrestricted grazing along the banks had resulted in a loss of bankside vegetation. This had resulted in both reduced spawning ground and erosion on the river banks.
We installed forty root wads over eighty metres of bank as well as brushwood.
As a result of our work there has been stabilisation of the complex outer meander bend and each of the live root wads have grown well. Gravels and silt have accumulated and encouraged vegetation growth.
