Innovative Sediment Distribution Pipe For Targeted Placement

All Natural or Nature-Based Feature (NNBF) projects along the coastline involve the construction of features that require, or would benefit from, targeted placement of sediment with specific gradation characteristics. These projects include marsh restoration projects where coarse-grained sediment (sand) is desired for building levees to improve containment of fine-grained sediment (silts and clay) material for maximum time of deposition on a marsh, as well as for its placement into deeper depressions (pans, pools, and ditches) to more efficiently achieve target elevation. Beach nourishment projects also have a maximum allowable fine-grained content that is allowed to be placed on the beach.
