Receiving water modelling involves the development of numerical tools to assist in the prediction of the fate and transport of dissolved and particulate species and pollutants in waterways.
Use of these models in a predictive mode enables stakeholders to assess likely changes in ambient water quality resulting from either management intervention strategies such as sewage treatment plant upgrade, or the discharge of newly proposed effluent.
For more than 20 years, BMT WBM has undertaken projects of this nature both within Australia and internationally on a range of receiving water environments including estuaries, rivers, lakes, reservoirs and coastal waters.
Recent Relevant Projects
Red Sea Modelling (Saudi Arabia)
The Red Sea is an iconic water body that supports extensive coral and associated reef ecosystems. BMT WBM undertook a modelling study of the Red Sea and a fringing lagoon to assist a large aquaculture operation to better manage its effluent stream entering the Red Sea in the vicinity of these corals. BMT WBM set up, calibrated and executed a range of predictive models of the area to assist our client in executing appropriate management interventions.
South East Queensland Water Quality Improvement Plan (Queensland)
Moreton Bay and its estuaries are of high social, economic and environmental value. BMT WBM assisted the Healthy Waterways Partnership to set future management strategies by setting up hydrodynamic and water quality numerical models of all these waterways. These models were used in predictive mode to estimate the water quality response of these waterways to future catchment land use and sewage treatment plant discharge changes. Management strategies were developed for the next 7 years with the goal of delivering sustainable pollutant loads to the combined system, based on these modelling outcomes.
Wivenhoe Dam Sustainable Loads Study (Queensland)
Wivenhoe Dam is Brisbane City’s largest potable water supply. Through the establishment of a suite of catchment and multidimensional receiving water quality numerical models, BMT WBM assisted SEQWater to better understand the response of Wivenhoe Dam to catchment-derived pollutant loads. In particular, the suite of models were used in concert to examine a range of water quality issues at varying spatial and temporal scales and as such to develop sustainable pollutant loads for each.
