Assessing future drought risk for water resources system management. The project aims to develop a new method for understanding drought drivers in eastern Australia and how well these are portrayed by climate models. The intended outcome of the project is to provide a framework for evaluating climate models on their representation of drought drivers and then use this information to develop improved downscaling schemes. Traditional downscaling approaches do not capture changes in variability in r ....Assessing future drought risk for water resources system management. The project aims to develop a new method for understanding drought drivers in eastern Australia and how well these are portrayed by climate models. The intended outcome of the project is to provide a framework for evaluating climate models on their representation of drought drivers and then use this information to develop improved downscaling schemes. Traditional downscaling approaches do not capture changes in variability in rainfall and evaporation at interannual and interdecadal timescales. This project aims to address this problem by providing a comprehensive drought downscaling framework which will provide inputs to water sharing plans that can be used to assess the future risks of droughts in catchments across New South Wales.Read moreRead less

Summary
Virtual reality for planning of green urban water infrastructure. This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify.

This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify. Using emerging virtual reality technology, participatory planning and operational models, this project intends to improve WSUD modelling science through integrated modelling. The anticipated outcome is more holistic and economically efficient planning of WSUD layouts in future cities. This is expected to address growing concerns about adequately managing these systems and ensure that they deliver intended environmental protection, liveability and public health benefits.Read moreRead less
Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries. Old quarries are increasingly used for the construction of landfills. The engineering challenge in constructing such landfills includes developing an appropriate lining system for the often steep sided quarry walls. The use of GCLs as part of the lining system can be a viable and a cost effective solution. However, this solution suffers from the lack of meaningful data on ....Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries. Old quarries are increasingly used for the construction of landfills. The engineering challenge in constructing such landfills includes developing an appropriate lining system for the often steep sided quarry walls. The use of GCLs as part of the lining system can be a viable and a cost effective solution. However, this solution suffers from the lack of meaningful data on their hydraulic durability in this particular situation. This proposal presents an original approach to investigate this durability under operating conditions typically encountered in steep sided quarries. This work is expected to provide benefits to waste containment efforts at national and international level.Read moreRead less
Settlement of municipal solid waste. The mechanisms governing municipal solid waste settlement are many and complex. There is a clear need to adopt a methodology to forecast the landfilling space based on high quality full scale data where composition, method of placement, compactive effort employed during placement of the waste, thickness of daily cover, stage filling and local moisture content are all recorded. This is the only sound scientific way forward to develop a predictive model that ....Settlement of municipal solid waste.

There is a clear need to adopt a methodology to forecast the landfilling space based on high quality full scale data where composition, method of placement, compactive effort employed during placement of the waste, thickness of daily cover, stage filling and local moisture content are all recorded. This is the only sound scientific way forward to develop a predictive model that links settlement to these parameters. This project will contribute to developing such a methodology for the benefit of the Australian waste containment industry.Read moreRead less
Development of a new technique to improve very soft soils using geogrid wrapped stone columns. Many large Australian infrastructure projects will be developed in regions with inherently poor soil conditions. Port developments, for instance, are by their nature located in river estuaries which are characterised by deep deposits of soft alluvial soils. Many highway projects also traverse low-lying ground or coastal regions with soft soil conditions. This project will develop a novel technique to ....Development of a new technique to improve very soft soils using geogrid wrapped stone columns. Many large Australian infrastructure projects will be developed in regions with inherently poor soil conditions. Port developments, for instance, are by their nature located in river estuaries which are characterised by deep deposits of soft alluvial soils. Many highway projects also traverse low-lying ground or coastal regions with soft soil conditions. This project will develop a novel technique to improve the engineering characteristics of very soft soils (shear strength lower than 15 kPa) by using geogrid wrapped stone columns. The effectiveness of this technique will be investigated in both small scale laboratory tests and field trials.Read moreRead less
The Development of a Model for Confined Water Sensitive Urban Design (WSUD) Stormwater Filtration/Infiltration Systems for Australian Conditions.

There is an increasing strain on scarce Australian water supplies and this requires effective water cycle management and protection of water resources as a whole. The proposed research aims to develop a model for the effective management of stormwater runoff through the investigation of confined filtration and infiltration devices in four separate locations. These confined systems will minimise the impacts of pollutant concentrations on native soils and groundwater. A model will be developed to predict required native soil permeabilities and residence times for adequate tertiary treatment in a variety of Australian conditions for non-potable reuse of runoff and/or groundwater recharge.Read moreRead less
Permeable Pavements with Concrete Surface Layers- Experimental and Theoretical Basis for Analysis and Design. Permeable pavements constitute unique and effective means to address important environmental issues and support green, sustainable growth. By capturing stormwater and allowing it to seep into the ground, porous pavements are instrumental in recharging groundwater, reducing stormwater runoff and preventing pollutants from entering the Australian river systems and sea-shores.

Permeable pavements constitute unique and effective means to address important environmental issues and support green, sustainable growth. By capturing stormwater and allowing it to seep into the ground, porous pavements are instrumental in recharging groundwater, reducing stormwater runoff and preventing pollutants from entering the Australian river systems and sea-shores. Other advantages for Australian communities that are associated with the construction of permeable pavement arise from their properties such as acoustic and thermal insulation due to the high void content of the material. Thus, permeable pavements improve on the living conditions in urban areas by reducing noise levels and preventing urban heat island effects.Read moreRead less
Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on repo ....Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on reported methane emission levels and there is need to undertake a range of activities to reduce emissions from waste management activities. This project will address specifically the above issue by providing a new method of analysis to predict gas leakage rate and allow engineers to propose solutions to mitigate gas escapes.
