Thin Layer Placement

Dredge Cycle ReDistribution Continuum

Redistribution

HYDRAULIC DREDGEVacuum collecting sediment; pumps to provide dislodging force

Sediment transfer through pipeline, pump or hopperPump directly to disposal site in slurry form

EXTRACTION

MECHANICAL DREDGEDislodge hard-packed material and move to surface

Transported through barges and hoppers

DISTRIBUTIONHORIZONTAL TRANSPORT

HOPPER

THIN LAYER PLACEMENT

NATURAL

Use of hose or pipe for movement for direct placement

Movement of sediment to: drop into ocean, drop into CAD cell, deposit on land/distribution center

Placed on barge or hopper and distributed with hose in a thin layer

Deposited in a hook shaped pattern; uses existing patterns of wind, waves and ocean currents to aid in distribution

Switchgrass (Panicum Virgatum)Description: grows 3-5ft; drought resistantFunction: stabilizes soil and controls erosionHabitat: provides habitat for birds and insects

Smooth Cordgrass (Spartina Alterniflora)Description: grows up to 7ft; found in intertidal wetlands; most productive of marsh plantsFunction: 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 rootsHabitat: roots provide structure for organisms; habitat for birds, fish, and insects
