In Louisiana, when marshes subside, the soils and vegetation sink and flood.

Unfortunately, plants drown and die, and the marsh ends up becoming shallow open water. Marsh creation takes place when sediment is moved from a “borrow area” to a site of open water or damaged marsh to build a new soil platform for marsh vegetation.

Pipeline sediment delivery is a term used to describe the process of using dredged sediment. Sediment can be transported in a variety of ways including by barge, hopper dredge or through a pipeline in a water and sediment mixture called a slurry. Through pipeline sediment delivery, sediment can be moved for many miles very quickly over land or water to restore marshes, ridges, or barrier islands practically anywhere. The beneficial use of dredged material is an excellent source of sediment for the pipeline sediment delivery method
