Coding Error Isolation in Computerised Simulation Models with Application to Wastewater Treatment Systems. Simulation code verification through program testing and debugging is crucially important, but is tedious and often difficult. A novel approach will be studied in this project. The approach involves detecting coding errors through back-to-back testing using two independently implemented versions of a given mathematical model, and isolating the coding errors through systematically analysing ....Coding Error Isolation in Computerised Simulation Models with Application to Wastewater Treatment Systems. Simulation code verification through program testing and debugging is crucially important, but is tedious and often difficult. A novel approach will be studied in this project. The approach involves detecting coding errors through back-to-back testing using two independently implemented versions of a given mathematical model, and isolating the coding errors through systematically analysing the test error signal generated (the difference between the outputs of the two models). This is possible because one of the two versions is implemented in such a way that the test error carries an easily identifiable feature. This project could revolutionize the area of model verification.Read moreRead less

Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas.

Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a year in Australia alone. This project is a major joint effort by the Australian water industry and world-leading scientists to generate advanced knowledge and develop effective technologies for optimal odour and corrosion management in sewers, delivering large social, environmental and economic benefits.Read moreRead less

Assessing Oceanic and Tidal Forecast Data For Search and Rescue Purposes. Locating people lost and adrift at sea requires costly resources (aircraft, ships and rescuers) and accurate planning. Rescuers also require estimates of where currents will take them. Australian marine Search and Rescue (SAR) planning uses infrequent (typically once a week) satellite measurements of ocean currents to estimate drift patterns of people at sea. Recently developed ocean forecast models will potentially help ....Assessing Oceanic and Tidal Forecast Data For Search and Rescue Purposes. Locating people lost and adrift at sea requires costly resources (aircraft, ships and rescuers) and accurate planning. Rescuers also require estimates of where currents will take them. Australian marine Search and Rescue (SAR) planning uses infrequent (typically once a week) satellite measurements of ocean currents to estimate drift patterns of people at sea. Recently developed ocean forecast models will potentially help forecast currents between the satellite observations, but are unproven for SAR use at this time and do not include tidal influences. This research project will develop measures of reliability and accuracy of using Ocean Forecasts that include tide forecasts for improving SAR planning outcomes in Australian waters.Read moreRead less

Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer ....Optimum aeration strategies for shallow tidally flushed lakes. Shallow tidally flushed lakes frequently suffer from water quality problems which include catastrophic fish kills. Frequently these events are related to the response of a highly modified system to a natural event. One event is the change from a saline to a fresh environment with seasonal freshwater inflow, in which case the salt tolerant algal species dies. The balance between photosynthesis, sediment uptake, surface oxygen transfer and flushing is lost, with the result that the lake quickly becomes anoxic, resulting in fish kills. This project examines some aeration solutions to this problem.Read moreRead less
