Beneficial use of dredged sediment
Create a More Natural Shoreline
In recent years a couple of different projects have been undertaken at Brightlingsea (Essex) to reuse accreted sediment within the harbour. In 2017 a cutter suction dredger (CSD) was used to excavate and pump sediment around the yacht moorings (working alongside and underneath the boats and floating pontoons that remained in situ) in the South Channel and pump the silt into 23 borrow pits within the adjacent saltmarshes. These receptor pits had been dug after the 1953 floods in order to obtain material to build up the sea walls. They covered around 2 hectares and were situated between 500 and 1600 m upstream from the dredging area along Brightlingsea Creek. This work was undertaken under the EU Interreg 2 Seas initiative ‘Using Sediment As a Resource’ (USAR) this work was led by Exo Environmental and undertaken by Royal Smals Dredging and Miles Water Engineer Ltd.
