Environmental Water Quality - The Basics
There is growing evidence of major water quality problems throughout Australia. Environmental water quality is affected by a wide range of influences, the impact of which can be considerable. The main causes of poor water quality are pollutant discharges, the disposal of industrial effluent, stormwater runoff, acid sulfate soil runoff and the changes in hydraulics due to dredging works and development.
The maintenance and preservation of high levels of water quality are essential to our environment and the viability of marine and freshwater ecosystems.
BMT WBM's team of experts are renown for their ability to design and develop total water quality plans which meet the demand of our clients and the needs of our environment.
The Breakdown
Understanding the basic processes which occur in a waterbody.
Water quality data are of little value without a detailed understanding of how they arise, and what the functions and variables are that influence them. The accurate interpretation of "raw" water quality is crucial to define what is actually occurring in a water body, and what this may mean in terms of waterway management.
The relationship between water movement, exchange processes, pollutant loadings and resultant water quality levels.
A wide range of factors affect water quality, including the amounts and rates of pollutant input, the patterns of water movement/exchange and internal physical and biological processes within and between waterbodies. It is important to understand the relevance of all such processes to be able to gain a whole of system appreciation of water quality issues. The experience and knowledge of our engineers and scientists is invaluable in enabling the understanding of the key processes in an area and what management actions can be taken to affect them.
Simulating water quality processes - on a catchment basis, or a receiving water basis.
In nearly all investigative studies, some form of predictive capability is required. This capability can be used to improve the understanding of processes in an area that may be under investigation, and also to determine in a quantitative manner what the impacts of various management measures and options are. State of the art mathematical models of catchment and instream water quality processes, continuing experience in their application are accurate assessments.
Developing and assessment management techniques to ensure the protection of water quality levels.
Most water quality investigations and modelling exercises are intended to result in the development of some form of management and/or water quality improvement measures. We consider that our close links with Australian and overseas research institutions are an import consideration when developing pollutant management techniques and evaluating management options.
Integrated Engineering, Planning and Ecological Considerations
Development of drainage systems including pipe networks, overland flowpaths, structures and retention basins, ensuring that all waterway layouts and designs are ecologically sensitive. The development of drainage plans which adopt multi-use roles in waterway corridors including the consideration of floodwater conveyance, water quality/pollutant export control, environmental protection, public open space provision and regional transport linkages.
