Title: Analysis of Fremantle Inner Harbour Siltation Pattern

Authored by: Nicholls, M. A.

Abstract:

Situated in the mouth of the Swan River on the west coast of Australia, Fremantle Harbour is the major port for Western Australia. Analysis of bathymetric surveys of the Inner Harbour has revealed that areas of the harbour are becoming silted, which can impact future shipping activities. This CEED project sponsored by the Fremantle Port Authority determined factors causing siltation in the Inner Harbour and predict future depths of the harbour.

Analysing the bathymetry data from surveys of the harbour, a channel was found to have formed in the Inner Harbour. The meandering nature of this channel was found to be responsible for the patterns of siltation and erosion. An ADCP survey of harbour currents confirmed the finding of the meandering channel. Regression analysis of the bathymetry data allowed a model to be produced that could predict future harbour depths.
