HYDRAULIC DREDGE
Use of hose or pipe for movement for direct placement
Vacuum collecting sediment; pumps to provide dislodging force Sediment transfer through pipeline, pump or hopper Pump directly to disposal site in slurry form
HOPPER
Movement of sediment to: drop into ocean, drop into CAD cell, deposit on land/distribution center
MECHANICAL DREDGE
THIN LAYER PLACEMENT
Dislodge hard-packed material and move to surface Transported through barges and hoppers
Placed on barge or hopper and distributed with hose in a thin layer
NATURAL
Deposited in a hook shaped pattern; uses existing patterns of wind, waves and ocean currents to aid in distribution

Buoyant Matrix
Switchgrass (Panicum Virgatum) Description: grows 3-5ft; drought resistant Function: stabilizes soil and controls erosion Habitat: provides habitat for birds and insects
Smooth Cordgrass (Spartina Alterniflora) Description: grows up to 7ft; found in intertidal wetlands; most productive of marsh plants Function: aids in erosion prevention; pollution filtration Habitat: provides habitat for birds and insects
Function: fluctuates with the tides; anchored to the ground; filtration of pollutants; present along industrialized coastlines; allows for carbon sequestration; nutrient uptake from roots Habitat: roots provide structure for organisms; habitat for birds, fish, and insects
Regional Intervention Sites and Prototypes prototypical deployment strategy
Floating Wetlands Parameters: areas with vertically built and heavily constructed edges Transitional and temporary in places waiting for rehabilitation Benefits: temporary and movable; habitat creation; pollutant filtration
Marsh Revitalization Parameters: locations set back from federal channel and high levels of activity; must experience inundation Benefits: reduced sedimentation; pollutant filtration; habitat creation; use of excess dredge
MHT
MLT
Planted Rip-Rap Parameters: locations in need of stabilization along edges of shoreline Benefits: reduced sedimentation through stabilization; reduce dredge maintenance; habitat creation
