Hydrodynamic Modelling for the Townsville Port Expansion Study

The proposed expansion of the Port of Townsville involves significant dredging of sea bed materials to provide for vessel access, maneuvering and berthing.

Background

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.

Outcomes and Benefits

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.
