Modelling and testing corroding reinforced concrete structures. The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion.

The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction of both active steel reinforcement corrosion and the time to concrete cracking in a chloride environment. It then plans to develop a non-destructive method, combining ultrasonic waves-based technology and acoustic emission, to detect active steel corrosion before any damage is visible on the structure.Read moreRead less
The characterisation of wastewater distribution patterns for the production of decision support systems for pathogenic risk analysis in water catchments. The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk c ....The characterisation of wastewater distribution patterns for the production of decision support systems for pathogenic risk analysis in water catchments. The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk contamination sources. The diurnal collection of data is expected to show significant variations in the measured parameters associated with time of day, light intensity and temperature. Mapping of the sewage and nutrient loads throughout the year will provide base line data for identifying potential hotspots for targeting system upgrades or improved management programs.Read moreRead less
An experimentally-validated thermo-hydro-mechanical theory for waste containment lining systems. Geosynthetic clay liners are engineering systems that are widely used around the world to protect groundwater from municipal, industrial and mining contaminants. The project will conduct cutting-edge experimental, theoretical and computational research leading to a major improvement in their short-term and long-term performances.
Robust streamflow predictions by improving the identification of hydrological model structure. This project aims to provide Australian environmental agencies, design engineers and policy-makers with robust methods that better utilise observed environmental data and process understanding to produce hydrological models with stronger scientific basis and improved operational predictive ability in gauged and ungauged catchments.
Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.
Optimal scheduling of urban bulk water systems under uncertainty. This project will develop a new optimisation framework for planning and operation of urban bulk water systems that incorporates flexibility to adapt to changing circumstances. Population growth in major Australian cities, coupled with a potentially drying climate, is putting pressure on existing water supply. To avoid the risk of overinvesting and losing future flexibility, water utilities have to develop plans for the future, a t ....Optimal scheduling of urban bulk water systems under uncertainty. This project will develop a new optimisation framework for planning and operation of urban bulk water systems that incorporates flexibility to adapt to changing circumstances. Population growth in major Australian cities, coupled with a potentially drying climate, is putting pressure on existing water supply. To avoid the risk of overinvesting and losing future flexibility, water utilities have to develop plans for the future, a task made difficult by uncertainty about future climate and demand. The framework is intended to explicitly deal with uncertainty about future demand and climate change, to ensure that solutions can cope with plausible but unexpected futures. The project will apply this framework to the bulk water supply for Sydney.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 loca ....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

Summary
Integrated command and control facility for large-scale critical infrastructure management. This is a test bed facility for achieving sustainable operation of Australia's critical infrastructure, particularly at airports. The facility will enable an integrated and coordinated strategy to increase operational resilience while not losing sight of the complex nature and dynamic requirements of critical infrastructure management.
Determination of the condition and strength capacity of in-service timber poles in energy networks. The project addresses an important issue facing power industries and engineering community worldwide, that is, reliable and optimal management of power distribution infrastructures. The outcomes lead to new technologies that not only provide great social-economic benefits but advance knowledge and practice of the research at international level.
