Slurry/rock dredged materials is transported through self propelled dump barge or non propelled dump barge from the Back hoe dredger to the dumping in offshore Dry dredged material is transported by road on a vehicle. Slurry/sand dredged materials is transported though Trailer Suction hopper from the Trailer Suction dredger to the dumping in offshore Subsequent use of dredged material: This is also done through two steps such as: Land development and land reclamation of low lying areas Building dams to fend floods
