In this project we studied the wave-current interaction and coastal sediment transport using numerical modelling and field data. The analysis was carried out at the Port Phillip Heads. Starting from existing data such as bathymetry and current speeds, the SCHISM-WWM numerical model was set-up using the appropriate mesh size to model wave-current interaction and coastal sediment transport. Once validated, the model was able to provide the missing data for the locations where the field observation are not available.

Hydrodynamics model can also be coupled with ship response models to investigate the Under keel clearance (UKC), which is the minimum distance between the sea floor and the vessel. UKC is essential to operate ships and port facilities safely and, through loading, critical to the profits of the shipping business. Improvements in accuracy of UKC will allow ships to load more and ports to dredge less, increasing revenues and reducing costs for million of dollars. This can also be extended to support a broad range of marine activities such as nearshore and offshore navigation, offshore oil and gas operations, marine renewable energy, recreational activities and ship simulation technology.
