Advanced Nanocomposites for Enhanced Containment of Hyper-Saline Leachate. This research project seeks to apply nanotechnology approaches to develop tailored materials that are green and cost-effective, which minimise groundwater contamination by hyper-saline industrial leachates and process waters. Australian industries will benefit from lower costs associated with storage, processing and reclamation of process waters, as well as from reduced environmental fines levied by the Environmental Prot ....Advanced Nanocomposites for Enhanced Containment of Hyper-Saline Leachate. This research project seeks to apply nanotechnology approaches to develop tailored materials that are green and cost-effective, which minimise groundwater contamination by hyper-saline industrial leachates and process waters. Australian industries will benefit from lower costs associated with storage, processing and reclamation of process waters, as well as from reduced environmental fines levied by the Environmental Protection Agency due to significantly reduced barrier failure and groundwater contaminations. Australian businesses involved in manufacture, design and construction of environmental barrier systems will have access to new materials and improved technology.Read moreRead less
Computer simulation and field application of tidal buffering and sub-surface alkaline barrier techniques to enhance acid sulphate soils management. In low-lying coastal areas, groundwater drawdown due to deep flood mitigation drains and prolonged droughts has exacerbated sub-surface pyrite oxidation, forming sulphuric acid. The distribution of acid following rainfall affects soil-water quality. The pressures of urban development in the Shoalhaven floodplain (civil infrastructure, agriculture, aq ....Computer simulation and field application of tidal buffering and sub-surface alkaline barrier techniques to enhance acid sulphate soils management. In low-lying coastal areas, groundwater drawdown due to deep flood mitigation drains and prolonged droughts has exacerbated sub-surface pyrite oxidation, forming sulphuric acid. The distribution of acid following rainfall affects soil-water quality. The pressures of urban development in the Shoalhaven floodplain (civil infrastructure, agriculture, aquaculture and recreational industries) necessitate the accurate prediction of acid migration. Therefore, the key challenge will be the development of comprehensive numerical models, which include complex estuarine hydrogeology and tidal dynamics, supported by field monitoring. Using these models, the novel concepts of 2-way floodgates that promote tidal flushing and the effectiveness of sub-surface alkaline barriers can be tested in the Shoalhaven, and subsequently applied globally.Read moreRead less
