Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This in ....Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This investigation is part of a genuine international effort that will develop new procedures to ameliorate water-repellent soils. New and improved mathematical models and decision support tools will also be developed to improve water-repellent land management, reduce environmental risk and minimise agriculture production loss.Read moreRead less
Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such ....Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such lakes and assess the possibility of using mining lakes as valued water resources in these regions. The primary outcome of the research will be improved management of the lakes for optimal long term water quality.Read moreRead less
Optimising biodegradation and removal of organic and inorganic pollutants in wastewater using constructed wetlands. The urgency of water recycling is dictated by drying climate and rapid expansion of population in Australia.

This project will research and develop a full-scale effluent reuse wetland to manage acid sulfate soils, regenerate wetlands and sequester atmospheric carbon. Many rural communities worldwide are affected by acid sulfate soils, unsustainable effluent disposal and wetland degradation, and the Greenhouse Effect threatens all coastal areas worldwide. This project is located at Byron Bay, a coastal and predominantly rural electorate in northern NSW that is strongly affected by this combination of environmental stresses, causing serious degradation of water quality culminating in regular fish kills. The technology developed from this project will be readily transferable to other rural coastal communities worldwide.Read moreRead less
PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. ....PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. Extensive 1D and 2D laboratory experimental programmes will be carried out. Models of unit processes that occur in infiltration systems will be defined/developed and built into a physically based model of an infiltration system. This model could be used for reliable design of stormwater drainage and harvesting systems, bringing major benefits to the people of drier and more populated areas of Australia.Read moreRead less

This research project will aim to prove the concept that emissions models capable of modelling changes in driver behaviour can be obtained from data that has been used as part of the vehicles emission certification process. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of operation. These models will then be able to describe the changes in emission characteristics under different vehicle operating modes modes for a range of vehicle types.Read moreRead less

As public interest on environmental conservation increases, tougher regulations on vehicle emission and fuel consumption will be implemented causing likely further restrictions on fuel consumption while operating the air conditioning system. Currently air conditioning and engine systems are controlled by two separate programs and lack effective communication between each other. This research aims to gain better understanding of the quantitative effects of car air-conditioning systems on fuel consumption and various air pollutant emissions, and develop an integrated simulation tool that links the air conditioning, engine fuel consumption and emission to assist the achievement of optimum vehicle energy and emission management.Read moreRead less
