Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transpor ....Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transport processes in marsh soils, will lead to (1) better understanding of the marsh's response to anthropogenic stress; and (2) improvement of strategies and methods for marsh wetland preservation and restoration.Read moreRead less
Ocean response to tropical cyclone forcing on the Australian North West Shelf. Tropical cyclones are a major hazard for the offshore oil and gas industry. This project will develop the ability to predict the ocean response to tropical cyclones, leading to a paradigm shift in the way industry designs and operates both present and future offshore projects.
Tidal generation of internal waves and currents. The North West Shelf (NWS) is a region of great significance to Australia, due mainly to the presence of the multi-billion dollar oil and gas industry, but also for fishing and national defense issues. This project will combine laboratory, numerical and field studies to quantify the production of internal waves on the NWS. The results will aid engineering design of offshore pipeline and structures, for both current production facilities and for fu ....Tidal generation of internal waves and currents.

This project will combine laboratory, numerical and field studies to quantify the production of internal waves on the NWS. The results will aid engineering design of offshore pipeline and structures, for both current production facilities and for future developments in deeper waters. The project will also provide quantitative knowledge and predictive behavior of the marine environment, allowing the development of earth and marine resources in a sustainable and informed way to protect the marine-based biodiversity.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 p ....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
Transient coastal upwelling along Western Australia: The dynamics of the Ningaloo Current system. This project will lead to significant advances in our understanding of the Ningaloo Current system that dominates the regional circulation surrounding Ningaloo Marine Park, part of the National Representative System of Marine Protected Areas. The numerical model and field measurements will, for the first time, elucidate which physical factors drive the Ningaloo Current and the resulting spatial and ....Transient coastal upwelling along Western Australia: The dynamics of the Ningaloo Current system. This project will lead to significant advances in our understanding of the Ningaloo Current system that dominates the regional circulation surrounding Ningaloo Marine Park, part of the National Representative System of Marine Protected Areas. The numerical model and field measurements will, for the first time, elucidate which physical factors drive the Ningaloo Current and the resulting spatial and temporal variability of upwelling. This will ultimately provide insight into how various ecological processes are linked to hydrodynamics (e.g., nutrient delivery, bleaching) and help assess how susceptible the reef ecosystem may be to changes to physical forcing resulting from climate change.Read moreRead less

This will ultimately provide insight into other similar systems with complex coastal topography, such as the Great Barrier Reef, and provide the frame work to understand the various physical processes that drive the marine ecology of the region.Read moreRead less
Physical processes in complex coastal reef environments: the dynamics of wave- and tide-dominated systems. Coastal reefs are ubiquitous features of Australia's coastline, yet the dynamics controlling water motion on reefs still remain poorly understood. This project will significantly advance our understanding of coastal processes within reef environments, thus improving predictions of the impacts of extreme storms and climate change on our coasts.
Wave dynamics in topographically-complex coastal reef systems. Both tropical coral and temperate rocky reefs are abundant features of Australia's coastline, yet their hydrodynamics (waves, currents and water levels) are poorly understood relative to other coastal environments such as beaches. This project will elucidate the complex hydrodynamic processes when waves interact with the steep-slopes and large bottom roughness of reefs, by establishing an international research program combining labo ....Wave dynamics in topographically-complex coastal reef systems.
