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
Sustainable planting of trees in suburban environments on shrinkable clays. Sustainable planting of trees in suburban environments on shrinkable clays. This project aims to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments. Trees are vital to urban environmental sustainability, but local government, house-owners, engineers and the building industry are concerned about building damage and settlement from tree root ....Sustainable planting of trees in suburban environments on shrinkable clays. Sustainable planting of trees in suburban environments on shrinkable clays. This project aims to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments. Trees are vital to urban environmental sustainability, but local government, house-owners, engineers and the building industry are concerned about building damage and settlement from tree root drying. If tree water needs and patterns of moisture extraction were predictable, house footings could be designed reliably. This research will provide such understanding through field experiments on suburban sites with trees, investigating damaged structures and numerical modelling. An anticipated outcome of this research is to develop a rational and reliable model to reduce the risk of damage to structures and increase tree plantings in suburban environments. Guidelines for both footing designers and local government.Read moreRead less
Cost-effective integrated engineering and "community partnerships" solution to a latent water policy issue: private dam management and flood safety. Project aims to further develop an engineering model for cost-effective innovative flood safety design/review for private dams in Southeastern Australia and integrate this with community impact assessment. Together, this is a "community partnerships" solution to a significant water policy vacuum on private dam safety and flood policy. Expected outco ....Cost-effective integrated engineering and "community partnerships" solution to a latent water policy issue: private dam management and flood safety. Project aims to further develop an engineering model for cost-effective innovative flood safety design/review for private dams in Southeastern Australia and integrate this with community impact assessment. Together, this is a "community partnerships" solution to a significant water policy vacuum on private dam safety and flood policy. Expected outcomes: improved risk transparency for dam owners and State Government, minimising costs of failures, ie. loss of life, damage to public and private infrastructure and environment; giving owners an affordable and effective design/review procedure to better manage their dams, providing data on community responses and water law reform proposals consonant with international best-practice.Read moreRead less
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.
