Dredging, an essential activity of coastal infrastructure development, has the potential to impact the marine environment. As part of the Environmental Impact Assessment (EIA) process, dredge plume modelling is routinely undertaken to help predict the intensity and extent of potential impacts to marine benthic habitat. To improve the quality and robustness of impact prediction, CSIRO has led the development of a practical guideline on key aspects of dredge plume modelling which require careful consideration and analysis. The Guideline represents a synthesis of extensive literature review, new research, and key learnings from the Western Australian Marine Science Institution (WAMSI) Dredge Science Node (Themes 2 and 3). The Guideline strongly recommends that a public database to support dredge plume modelling be established and all relevant data be made available. The database will greatly improve the availability of reference information at the EIA stage, assisting both those responsible for the EIA preparation, and for interpreting and approving the dredge activity. It is hoped that the dredge plume modelling guideline will provide increased confidence in modelling outcomes, leading to a reduction in the monitoring and management burden required by regulators and increased transparency and public confidence in the EIA process.
