The Water Research Laboratory has extensive modelling capabilities and computing resources for undertaking complex environmental modelling studies. These modelling capabilities include: 1D, 2D and 3D hydrodynamic and water quality, near field dispersion, sediment transport/turbidity, reservoir mixing, wave refraction and catchment runoff.
Currents, waves, pollutant transport and water quality are all complex processes that can be investigated with the proper use of numerical modelling. At WRL, a strong emphasis is placed on understanding the physical and chemical properties of the processes being modelled to ensure reliable modelling outcomes. Studies often start with pilot modelling to assist in the design of data collection programs, followed by development of calibrated models to undertake scenario testing. Staff undertaking modelling are experienced engineers and scientists who both understand environmental processes and the mathematics behind the modelling.
WRL has undertaken environmental modelling of many ocean outfalls and STP/sewer overflow releases to determine either the current impacts or to assess relative impacts from different discharge scenarios. Other studies include the assessment of environmental flow regimes and their relative effects on ecology, utilising models to aid with the design of dredging programs and comparison of the effects on water quality of varied operational and engineering options in drinking water reservoirs.
A range of modelling tools are utilised including the RMA suite of models, which WRL has actively contributed to the development for over 12 years. WRL has a bank of high speed Linux workstations on which all modelling is undertaken.
