Client: Port of Townsville/AECOM
The proposed expansion of the Port of Townsville involves significant dredging of sea bed materials to provide for vessel access, maneuvering and berthing. A significant quantity of the dredged material will be used to reclaim land, providing for further port development.
A TUFLOW-FV model was developed which enabled efficient 3D modeling of hydrodynamics and suspended sediment transport. The model was used to simulate the advection and dispersion of sediment plumes produced during dredging operations.
The model was also used to simulate potential re-suspension of sediment from the dredge material placement area, and natural re-suspension of sediments throughout Cleveland Bay. The model results were used to estimate sedimentation rates in the harbour and dredged channels.
Fremantle Ports trusted BMT to oversee marine monitoring of major dredging and reclamation works, in full public view, for Western Australia's largest metropolitan port.
Fremantle Ports engaged BMT to project manage and provide expert technical advice on marine environmental assessment of a major port facility.
BMT was engaged by Gippsland Ports to investigate the existing system to maintain safe navigation through the channel.
BMT undertook an analysis of recent wind and wave conditions at the site to evaluate the relative severity of winter storms and provide an indication of the metocean drivers behind wrack accumulation and removal.
