The South Australian Department for Water, Land & Biodiversity Conservation and the Murray-Darling Basin Commission are working together with BMT to apply state-of-the-art models to assist in optimising river flow benefits for improved environmental management of the Coorong.
Advice has also been provided since 2002 on the dredging strategy which has been adopted to keep the mouth open in the absence of sufficient river flow.
Outcomes and Benefits
The model provides a reliable basis for quantified evaluation of various flow management options to keep the river mouth open with minimal inflow of beach system sand to the Coorong. The models also have much wider application to other environmental issues throughout the Lower Murray of significance to aquatic communities, migratory bird habitats, fisheries and water quality.
The model extends to the limits of tidal influence in the Coorong and upstream through the Lakes Alexandrina and Albert to Lock1, incorporating the barrages, and offshore to include wave and coastal processes. The model has been used to assess the potential impacts and benefits for a range of hydrodynamic, water quality and ecological processes, including bird habitat conditions within the Ramsar wetland areas.
Services and Expertise Provided:
BMT was commissioned to develop a three dimensional hydrodynamic, sediment transport and water quality model of the Tamar River, Tasmania. The model was extensively calibrated and used by a range of stakeholders to examine the efficacy and impact of a range of management measures.
BMT developed a 3D hydrodynamic and water quality model of the region around the Abrolhos Islands in Western Australia. In collaboration with BMT Oceanica and University of Western Australia, model results were used to assess the impact of proposed finfish aquaculture on the surrounding environment.
The Brisbane River Catchment Flood Study is the most detailed and comprehensive flood study ever undertaken in Australia. The hydraulic models that were developed underwent rigorous calibration. A sophisticated Monte Carlo approach was used to hydraulically model 11,340 flooding scenarios. The result was a robust and defendable set of design events. The study was fully peer reviewed by a panel of independent experts.
BMT was contracted by TOTAL (Paris) to undertake cooling water discharge modelling studies on behalf of Shtokman Development AG.
