Remotely operated vehicle-based methodology for the reduction of costs and operational delays associated with rock dredging for channel deepening

Rock dredging for river channel deepening presents problems concerning the identification of whether the blasted rock is properly fragmented for the following operations and whether the excavation and disposal reach the determined project level. These issues lead to decision making that involves exp...
