Hydrodynamic and sedimentary processes in sedimentation fields: the requirement for continued maintenance to preserve restored intertidal habitat

of sediment. This loss occurred despite indications from on-site sediment trap data that there is the potential for sediment to accrete at more than 10 cm/year at mudflat sites and up to 9 cm/year at saltmarsh sites. These results suggest that the created marsh is not self-sustaining, and continued maintenance of the sedimentation fields might be required. Further research is required into sedimentary processes in sedimentation fields, both to inform the management of such schemes and to identify suitable locations for future sedimentation field construction. Assessments of marsh functioning and ecosystem service delivery in sedimentation fields are also needed to provide justification for future implementations of this restoration method.
