Predictive capability for particle capture in aquatic ecosystems. This project investigates the fundamental fluid mechanics of particle capture, whereby suspended particles contact and adhere to a solid structure. This process is examined in productive and biodiverse ecosystems (such as coral reefs and seagrass meadows) whose health, productivity and propagation are directly controlled by particle capture. Existing formulations for particle capture are valid only under highly idealised condition ....Predictive capability for particle capture in aquatic ecosystems. This project investigates the fundamental fluid mechanics of particle capture, whereby suspended particles contact and adhere to a solid structure. This process is examined in productive and biodiverse ecosystems (such as coral reefs and seagrass meadows) whose health, productivity and propagation are directly controlled by particle capture. Existing formulations for particle capture are valid only under highly idealised conditions that are grossly unrepresentative of the complexity of ecosystem flows. The goal of this project is to use a coupled computational-experimental campaign to develop predictive capability for particle capture in ecosystems, where the flow can be turbulent and/or wave-dominated and the biological structures complex.Read moreRead less
A new framework for flow and mixing at the sediment-water interface. Ensuring the sustainability of Australia's freshwater resources is vital to the nation. This project addresses a fundamental, and as yet unanswered, question in our efforts to maintain the quality of our freshwater systems: "How important are the sediments?"
Redefining sediment transport predictions in benthic ecosystems. This project aims to understand and predict the mobilisation of sediment, and the rates and modes of sediment transport. Sediment dynamics control the health and productivity of some of the world’s most valuable marine ecosystems, including seagrass meadows and coral reefs. However, the theory and predictive models needed to quantitatively understand sediment transport over the large bottom roughness in these ecosystems has proven ....Redefining sediment transport predictions in benthic ecosystems. This project aims to understand and predict the mobilisation of sediment, and the rates and modes of sediment transport. Sediment dynamics control the health and productivity of some of the world’s most valuable marine ecosystems, including seagrass meadows and coral reefs. However, the theory and predictive models needed to quantitatively understand sediment transport over the large bottom roughness in these ecosystems has proven elusive. This project will integrate comprehensive laboratory and field programmes to develop predictive models of these sediment dynamics, which should help better understand, manage and protect these critical ecosystems and their services.Read moreRead less
