Implementing Sustainable Dredged Sediment Management Practices for Supporting Coastal Wetlands

Many wetlands are subsiding due, in part, to reduced mineral sediment input. Navigation dredged sediment that is not beach quality (>15% fines) has been identified as a resource that can support wetland resilience. Numerous wetlands have been constructed using dredged sediment. However, these construction projects are infrequent, costly, and considered targets of opportunity where dredge schedules must align with construction schedules. Therefore, the majority of dredged sediment continues to be removed from the regional sediment system.
