Abstract

Cockburn Sound is a coastal embayment located to the south of Fremantle on the Western Australian coast. The region is an important industrial centre, receiving numerous discharges to the Sound including those by Kwinana Power Station, BP Refinery, Tiwest Refinery and Water Corporation. In addition, the embayment supports multiple uses including commercial fishing, defence, recreation and provision of drinking water. Current and potential water quality issues facing the embayment include reduced circulation and sediment plumes arising from dredging and infrastructure development and thermal and saline plumes resulting from industrial discharges. The Centre for Water Research at the University of Western Australia has conducted a series of detailed validations of the Estuary, Lake and Coastal Ocean Model (ELCOM), coupled with the Computation Aquatic Ecosystem Dynamics Model (CAEDYM) applied to Cockburn Sound. The high public profile of the site and the extent of the industrial use required extensive stakeholder interaction in the model construction and validation. The validated and calibrated three-dimensional model has provided an integrated tool for numerous applications, across various spatial and temporal scales, including: • The impact of the Perth Seawater Desalinisation Plant on stratification and dissolved oxygen dynamics in the Sound; • The influence of harbour modifications in Jervoise Bay on flushing of the Australian Maritime Complex harbours; • The impact of Fremantle Ports Kwinana Quays development on circulation within the Sound; and • The impact of cooling water discharge from proposed High Efficiency Gas Turbines on thermal plumes. This paper presents the extensive validation process of ELCOM in Cockburn Sound, and the application of this integrated tool to assess the impact of numerous interventions on varying spatial and temporal scales. Future modelling directions will also be discussed. © MODSIM 2009.All rights reserved.
