The 2021-22 floods in Eastern Australia revealed the vulnerability of rivers to climate extremes. To prepare for a future with more intense floods, we must integrate nature-based flood mitigation strategies into river management. This project aims to address the potential of using Natural Flood Management (NFM) as a 21st Century flood mitigation solution. NFM uses natural processes to slow floods, reduce erosion, and minimise flood risk. Collaborating with NSW government partners the project expects to deliver scientific evidence for NFM and solutions for implementation in river rehabilitation, planning and community capacity building. The results will impact society's ability to adapt, reduce economic costs, and benefit the environment.Read moreRead less
Multi-scale ensemble modelling of coastal systems in a changing climate. This project aims to incorporate sandy shoreline adaptation by developing a time-varying framework for model ensemble averaging. This will significantly advance our ability to predict shoreline change over a range of management timescales from days to decades along high-value coastlines. This project expects to generate new knowledge in Coastal Engineering using new methods to train models and deliver unprecedented new shor ....Multi-scale ensemble modelling of coastal systems in a changing climate. This project aims to incorporate sandy shoreline adaptation by developing a time-varying framework for model ensemble averaging. This will significantly advance our ability to predict shoreline change over a range of management timescales from days to decades along high-value coastlines. This project expects to generate new knowledge in Coastal Engineering using new methods to train models and deliver unprecedented new shoreline data. The expected outcomes are enhanced capacity to predict shoreline change over a range of timescales and a better understanding of how sandy coastlines adapt to future climate variability. This should provide significant benefits by enabling a better assessment of coastal hazards along our high-value coastline.Read moreRead less
Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this p ....Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this project will ascertain the resilience of coastal wetlands to the cumulative impacts of fire and sea-level rise. Expected outcomes of this project include new, spatially-explicit fire management tools which will aid the sustainable, long-term management of coastal wetlands in a changing climate.Read moreRead less
Earth's Dynamic Topography Through Space and Time. A key component of Earth’s topography remains enigmatic. This so-called dynamic topography is transient, varying in response to convection within Earth’s mantle. This project aims to use a data-driven computational approach to: (i) reconstruct the evolution of dynamic topography over the recent geological history of our planet (Cenozoic Era, 0-66 million years ago); and (ii) uncover the mechanisms controlling its spatial and temporal evolution. ....Earth's Dynamic Topography Through Space and Time.

This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work. The project expects to provide a well-dated sequence for Kimberley rock art based on replication of results, confirmation across different methods, and a large interdisciplinary data set. The project will allow rigorous analysis of the relationship between dating results and rock art styles that has not previously been possible, and give new insights into Australia’s deep indigenous heritage. This will have a significant impact for future efforts in rock art conservation, and lay a foundation for cultural tourism, with important benefits for the local economy and health of regional indigenous communities.Read moreRead less
Palaeoclimatic and environmental significance of major Late Quaternary drainage contributions and disruptions in the Lake Eyre basin. This study will advance our knowledge of the most remarkable floods ever known to have occurred in Australia. They were associated with a vast aquatic ecosystem in what today is the barren northern end of the Flinders Ranges, a region of desert dunes and salt lakes.

This study will advance our knowledge of the most remarkable floods ever known to have occurred in Australia. They were associated with a vast aquatic ecosystem in what today is the barren northern end of the Flinders Ranges, a region of desert dunes and salt lakes. Remarkably, such wet conditions appear to have coincided with episodes of megafaunal extinction and with the human occupation of Australia. The results will provide valuable information with which to better understand the the main global drivers of episodes of profound wetness and dryness in Australian climate. Read moreRead less
How green were our deserts? Evidence for Late Quaternary climate change and the source of water in the Lake Eyre basin. This project addresses the National Research Priority of Environmentally Sustainable Australia by examining evidence for what has controlled climate change and variable runoff in the vast Lake Eyre basin.

Evidence for Late Quaternary climate change and the source of water in the Lake Eyre basin. This project addresses the National Research Priority of Environmentally Sustainable Australia by examining evidence for what has controlled climate change and variable runoff in the vast Lake Eyre basin. It will provide evidence for why Australia, presently the world's driest inhabited continent, has as recently as medieval times supported large lakes holding many cubic kilometres of fresh water adjacent to the now-barren Flinders Ranges. It will show if this water had a tropical or temperate source, fundamental information for understanding Australia's past climate, and allow predictions of future climate to be based on firm evidence.Read moreRead less

Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits. It exploits the radiation-induced thermally (TL) and optically stimulated luminescence (OSL) emissions from minerals exposed to sunlight before burial. Recent technical developments have made feasible OSL dating of small samples (e.g., individual sand grains) and sediments deposited during the past 0.5-1 million years. We request funds for a Risø TL/OSL system with single-grain attachment to resolve the timing of sea-level, climate and landscape changes, and the chronology of human evolution and dispersal, in Australia and Southeast Asia.Read moreRead less
