Summary
Mobile weather radar system for advanced environmental monitoring and modelling. High spatial and temporal resolution weather radar data on wind and precipitation will translate to significant environmental model advances. Australian researchers will undertake model validation studies on precipitation, dust storm, and flood prediction under a wider range of environmental conditions and in greater detail than currently possible.
Reducing flood loss - A data-assimilation framework for improving forecasting capability in sparsely gauged regions. Floods are the biggest and severest natural disaster we face year after year. Furthermore, there has been little improvement in our capability to prevent flood damage over past decades. This research proposes a paradigm shift in the way flood forecasting, warning and evacuation proceeds, using 21st century technologies for collecting and incorporating flood related data into exist ....Reducing flood loss - A data-assimilation framework for improving forecasting capability in sparsely gauged regions. Floods are the biggest and severest natural disaster we face year after year. Furthermore, there has been little improvement in our capability to prevent flood damage over past decades. This research proposes a paradigm shift in the way flood forecasting, warning and evacuation proceeds, using 21st century technologies for collecting and incorporating flood related data into existing modelling platforms. It is argued that assimilating real-time satellite soil moisture data into flood models can increase accuracy manifold, even if the images are uncertain. The understanding gained in course of the proposed project has the potential to significantly reduce the damage caused year after year, especially in the data poor regions of the world.Read moreRead less
Reconstructing Australia’s fire history from cave stalagmites. Fire represents a major natural hazard, and its impact on Australian communities and ecosystems is increasing. Representing a world first, this project aims to calibrate the paleofire signal from stalagmites in shallow caves, and to construct annually resolved stalagmite records of paleofire frequency and intensity for the last millennia. The project aims to use stalagmites from south west Australia to determine the relationship betw ....Reconstructing Australia’s fire history from cave stalagmites. Fire represents a major natural hazard, and its impact on Australian communities and ecosystems is increasing. Representing a world first, this project aims to calibrate the paleofire signal from stalagmites in shallow caves, and to construct annually resolved stalagmite records of paleofire frequency and intensity for the last millennia. The project aims to use stalagmites from south west Australia to determine the relationship between fire and climate and assess the robustness of stalagmite hydroclimate proxies in fire-prone regions. This project expects to establish a new research field for speleothem science, enhancing capacity for the Australian Quaternary and speleothem research communities, as well as benefits to land managers.Read moreRead less
Biomagnification of the biotoxin BMAA in the environment. Using unique models and technics, the project aims to demonstrate that long-term exposure to the blue green algae toxin β-N-methylamino-l-alanine (BMAA) leads to uptake, accumulation and toxicity within the central nervous system. The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood. Algal blooms cost the Australian community more than $250 million each year and represent a major health issue fo ....Biomagnification of the biotoxin BMAA in the environment. Using unique models and technics, the project aims to demonstrate that long-term exposure to the blue green algae toxin β-N-methylamino-l-alanine (BMAA) leads to uptake, accumulation and toxicity within the central nervous system. The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood. Algal blooms cost the Australian community more than $250 million each year and represent a major health issue for human and fauna. This project aims to be the first to fully characterise BMAA mechanisms of contamination and neurotoxicity and to highlight the major environmental risk of exposure of human to BMAA. It also aims to develop new and unique detection and quantification tools for BMAA.Read moreRead less
A spatial extremes framework for predicting subdaily rainfall intensity. Climate change is causing extreme rainfall intensity to increase globally. The greatest increases occur for short-duration storms lasting up to several hours, bringing a heightened risk of flash-floods that are often extremely hazardous due to their rapid onset. The project aims to develop a new spatial extreme value framework to predict extreme rainfall patterns, using insights on future changes to rainfall triggering mech ....A spatial extremes framework for predicting subdaily rainfall intensity. Climate change is causing extreme rainfall intensity to increase globally. The greatest increases occur for short-duration storms lasting up to several hours, bringing a heightened risk of flash-floods that are often extremely hazardous due to their rapid onset. The project aims to develop a new spatial extreme value framework to predict extreme rainfall patterns, using insights on future changes to rainfall triggering mechanisms (e.g. convective, frontal or orographic). The research aims to provide projections in the form of intensity-frequency-duration curves, areal reduction factors and antecedent rainfall depths. Engineers are expected to use this information to design infrastructure and urban planning policies to adapt to future flood risk.Read moreRead less
Assessing future drought risk for water resources system management. The project aims to develop a new method for understanding drought drivers in eastern Australia and how well these are portrayed by climate models. The intended outcome of the project is to provide a framework for evaluating climate models on their representation of drought drivers and then use this information to develop improved downscaling schemes. Traditional downscaling approaches do not capture changes in variability in r ....Assessing future drought risk for water resources system management. The project aims to develop a new method for understanding drought drivers in eastern Australia and how well these are portrayed by climate models. The intended outcome of the project is to provide a framework for evaluating climate models on their representation of drought drivers and then use this information to develop improved downscaling schemes. Traditional downscaling approaches do not capture changes in variability in rainfall and evaporation at interannual and interdecadal timescales. This project aims to address this problem by providing a comprehensive drought downscaling framework which will provide inputs to water sharing plans that can be used to assess the future risks of droughts in catchments across New South Wales.Read moreRead less

Probabilistic graphical models for detecting outbreaks. This project will create a novel class of probabilistic graphical model algorithms for learning and inference in problems involving unfrequent events such as anomaly detection. The outcome will be a methodology for seamlessly integrating space-time correlated data that will enable the early prediction of outbreaks in a principled statistical manner.
Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve ....Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve vegetation quality. It will investigate where corridors of recovery are, where to prioritise rehabilitation and the cost:benefit of working with recovery. This will benefit public policy, improve flood and drought risk analysis, and change decision-making and rehabilitation practice - essentially future proofing our rivers.Read moreRead less
