By Richard Edwards, Salix


Raised riverbed forming riffles


Salix designed and constructed a river enhancement project at Ickenham for a gas pipeline river crossing as ecological mitigation to a degraded reach of river as part of a major pipeline project.


Salix were set the task of enhancing a degraded reach of the River Pinn near Ickenham, which, as a result of previous modification was now characterised by slow water flow, over deep and ponded sections with a silty bed and steep banks covered in nettles


Salix designed and constructed a 50 metre enhanced channel. Imported flint reject stone was used to create in channel features, riffles and a point bar, that has concentrated the low flows and revived water flow in the reach.


Diverse marginal and bankside vegetation was established using mature pre-established coir rolls and pallets.


Locally harvested tree trunks were used to create a double flow deflector. Additionally, a large backwater was created on line and just downstream of the enhanced reach.
