Tender: Foresters Lodge River Restoration and Wetland Creation – Two-Stage Floodplain, New Sinuous Channel and In-Channel Woody Deflectors

About

An experienced environmental contractor is sought to deliver river restoration and wetland creation works at Foresters Lodge in line with the Design Report. The contractor will bench a two-stage floodplain and excavate a new sinuous second flow channel on the right-hand bank fed by hillslope drainage and higher flows via bankside scrapes and in-channel woody material, install in-channel woody deflectors by felling designated trees and fixing root plates/trunks into the bank, excavate scrapes and floodplain pools, and construct interconnected contoured scrapes to divert existing drains and springs into the new channel to improve on-site water retention and attenuation. These measures are intended to activate the upper bench at approximately Qmed (about a 1 in 2 year return period), divert spate flows at Q4/5 into the floodplain, reduce channel incision and erosive forces, promote sediment deposition and increase the reach’s resilience to drought and high-intensity rainfall events.
