3.1.3 Review – numerical modelling of dredge plumes

Description

This review provides a synthesis of the current knowledge on several key processes for sediment transport modelling, and standard practice of sediment transport modelling around the world with a particular focus on the applicability to tropical marine waters off north Western Australia, and tropical Australia more broadly. A number of EIA modelling studies around tropical Australia associated with coastal infrastructure developments are also reviewed. Factors contributing to the accuracy in model predictions are assessed and the effectiveness of monitoring and managing the impacts during dredge operations.

Aims

• To critically evaluate approaches in parameterizing important processes in hydrodynamic but especially in sediment transport.
• To provide recommendations on modelling and summarise best practice parameters and guidance in the final report
