Project Description: The purpose of this demonstration project is to provide the foundation for use of thin layer placement of dredged material in similar location by developing a list of parameters and models predictions that are necessary for applying thin layer placement of dredged material to coastal wetlands. The project site is located adjacent to the AIWW as it traverses MCBCL behind the Onlsow Beach barrier island. The results of the Coastal Wetland monitoring program indicate that the marsh platform at the project site is 20-25 cm below “optimal” growth elevations for Spartina alterniflora. Approximately 5 to 10 cm of dredged material were placed in three experimental plots in March/April 2017. The site was monitored before thin layer implementation and will be monitored every 2 months for 2 years.
