Resilience of Nature Based Features for Protection of Constructed Wetlands

Project Information

Wetlands support both habitat and flood risk reduction missions of the Corps. Wetlands that are managed or supported by the Corps are often near navigation infrastructure or in open-water. Therefore, protection from erosive forces is sometimes required. The Corps therefore builds berms to absorb wave energy and protect both constructed and natural wetlands from erosive forces produced by naturally occurring waves or navigation activity. These constructed berms are typically sandy. Dredged sediment is sometimes used in the construction process. However, most dredged sediment is a mixture of sand, silt and clay which limits their application to berm construction. Increased use of mixed sediment for construction of protective berms would greatly expand this sustainable, beneficial use of dredged material.
