Abstract:

This report provides guidelines for the evaluation of vegetative stabilization alternatives for dredged material disposal areas using salt marsh wetland plants. The guidelines provide a methodology for classifying dredged material shorelines with respect to wave energy low, moderate, or high energy sites and specify a vegetative stabilization strategy standard planting techniques, root-anchored techniques, or wave protection structures for each energy regime. Such guidelines provide dredged material planners and operations personnel the means to use dredged material for combined beneficial uses of wetlands creation, habitat development, and erosion control. The report also presents two case studies of salt marsh creation on dredged material sites located in North Carolina along the Atlantic Intracoastal Waterway and in Texas along the Gulf Intracoastal Waterway near Galveston. These studies provide guidelines for creating salt marsh on moderate- to high-energy sites exposed to both ship and wind generated waves.
