Coastal wetland loss is a critical environmental problem across the United States. These ecosystems provide vital services to people and the environment including erosion control, flood protection, carbon sequestration, and maintenance of water quality. The natural flood protection has already been greatly weakened by coastal land loss in Louisiana and similar deltaic areas throughout the world. If this trend continues, many communities are at severe risk of physical and infrastructural damage. One of the proposed methods to reverse the erosion of the coastal wetlands is marsh creation. Comprehensive characterization of the dredged sediments is crucial in successfully constructing a marsh creation project. The settling characteristics of the dredged material are affected by organic content, solids concentration, and geotechnical properties of the sediments. The effects of organic content on settling characteristics are evaluated and discussed. The zone settling velocity was lower for dredged slurry with higher percentages of organic matter.
