Summary
Modelling and simulation of instabilities in unsaturated soils due to wetting. Ground instabilities due to wetting are a critical issue that will be investigated through this project via the development of risk assessment tools. A rational engineering approach and calculation framework will be developed in order to predict failures and facilitate the design of new safer structures.
Improved Management of Australian Port Infrastructure by Development of Predictive Ageing Simulation. Exposure of built infrastructure to corrosive marine conditions causes deterioration and reduced service life. Asset managers lack predictive models of in-service durability. Using data gathered from Australian ports, life-cycle predictions will be developed, simulating durability and incorporating geographical location, structure type, composition, and levels of maintenance. The modelling has ....Improved Management of Australian Port Infrastructure by Development of Predictive Ageing Simulation. Exposure of built infrastructure to corrosive marine conditions causes deterioration and reduced service life. Asset managers lack predictive models of in-service durability. Using data gathered from Australian ports, life-cycle predictions will be developed, simulating durability and incorporating geographical location, structure type, composition, and levels of maintenance. The modelling has not been undertaken on Australian port assets, whereas international models reflect very different infrastructure and exposures and are based on simpler 2D conditions that do not simulate actual deterioration. The three-dimensional (3D) modelling and graphics will be unique worldwide, providing decision support for construction and maintenance.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
Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient co ....Dynamic Release Mechanisms for Phosphorus in Shallow Ponds and Lakes. Phosphorus release from submerged sediments is controlled by the physical and chemical environment. The mechanisms are well understood where thermal stratification is persistent but the behaviour during transient episodes has not been properly addressed. The aim is to study a dynamic chemical and hydraulic environment and develop a model of phosphorus release under these conditions. Algal blooms, which rely on high nutrient concentrations, pose a significant threat to waterways yet a process-based description of phosphorus release is not yet possible. The outcome will be a verified model of phosphorus release mechanisms suitable for a range of water bodies.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. Other advanta ....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. 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

Internal wave energetics, mixing and transport in lakes. The aim of this project is to increase our understanding of the physical processes controlling water quality in lakes. Water supplies world-wide are under increasing pressure from development, usually resulting in decreasing water quality.

The biology and chemistry in lakes is controlled primarily by physical processes, and so understanding these processes is crucial to managing water quality in lakes and reservoirs. The outcomes of this project will be improved tools for the management of these water resources, as all the research findings will be incorporated into already existing numerical models for lake management.Read moreRead less
